--------------------------------------------------------------------------------
What is the ZyXEL FAQ?
--------------------------------------------------------------------------------
The ZyXEL FAQ is a source of information about ZyXEL modems. It contains a
list of Frequently Asked Questions (and answers) that are most commonly asked
by people.
Since the FAQ is too large to be a single file, it is broken into five (5)
logical parts. Below is the name, and purpose of each part:
ZyXEL FAQ-Introduction
This part serves as the introduction to the rest of the FAQ.
ZyXEL FAQ-Frequently Asked Questions
Common questions of a less technical nature are answered.
ZyXEL FAQ-Technical Frequently Asked Questions
Containing questions of a more technical nature, this section is
organized into various subsections
. ROMs, & ROM images
. modem certifications, country codes, & power supplies
. data modem questions
. fax modem questions
. voice questions
. other questions
ZyXEL FAQ-Information Sources and ISDN
This section serves as a pointer to other resources of ZyXEL modem
and ZyXEL-modem related information. FTP sites, mail servers, mailing
lists, and CELP references are listed. Information about V.34, ISDN,
and the new modems is found here.
ZyXEL FAQ-Product Information
Various software products on different platforms are listed. ZyXEL
modem vendors are also listed.
--------------------------------------------------------------------------------
Where to get the ZyXEL FAQ
--------------------------------------------------------------------------------
The ZyXEL modem FAQ (Frequently Asked Questions) list can be obtained in a
variety of ways:
Internet:
1) Anonymous FTP to rtfm.mit.edu and get the file in
/pub/usenet/news.answers/modems/ZyXEL/FAQ/part[1-5]
2) Randy McCaskill (rmccask@comm-data.com) has made the complete ZyXEL FAQ
available to the World Wide Web (WWW) users at
http://www.comm-data.com/zyxel/
2) The complete FAQ is also posted in the comp.dcom.modems, comp.dcom.fax,
comp.answers, and news.answers newsgroups.
3) E-mail Robert Wong (rwong@direct.ca) and request a copy to be e-mailed
to you. The FAQ is about 178 kbytes (uncompressed) or 105 kbytes
(compressed and uuencoded) in size. To save on transmission costs,
the FAQ is usually sent as a compressed/uuencoded message.
UUCP recipients should ensure that sufficient hard disk space exists on
both UUCP host machines, and the final recipient. Also, UUCP recipients
should be aware that the sheer size of the FAQ might violate some
transmission/hard disk/etc. quotas that might be imposed by the UUCP
administrator.
4) E-mail Robert Wong (rwong@direct.ca) and request to be put on the FAQ
distribution list. You will automatically receive the FAQ in compressed,
uuencoded format (faq.Z.uue) when it is posted. Please ensure that you
have the ability to receive a 105+ kbyte e-mail message and you can
uudecode/uncompress the FAQ.
Fidonet:
1) Jussi Torhonen (jussi.torhonen@kone.com), 2:220/405 [FidoNet] reposts the
FAQ from a BBS in Finland. It is posted to the "ZyXEL modems" echo
conference. All you have to do is to collect all the pieces of the FAQ
(31+ parts) and you have the complete file.
2) Frog Hollow BBS (604) 469-0264 (1:153/290) has the FAQ in a file area.
a) File REQuests (FREQs) are possible from this BBS at anytime except ZMH.
Use the magic name of ZYXELFAQ. OR:
b) Download the file after you have signed onto the BBS.
ZyXELnet:
1) The FAQ is emailled to Kolja Waschk (kawk@Yo.COM). He then zips the file
and sends the file to Mirko Mucko, who hatches it immediately into
the ZyXELnet "ZYXTEXT" file area.
--------------------------------------------------------------------------------
How to send a submission
--------------------------------------------------------------------------------
All submissions are gratefully welcomed.
Contributions may be slightly paraphrased in order to clarify and/or better
establish the context of the submission. Any misunderstanding due to this
paraphrasing in entirely due to the Keeper of the FAQ.
Below is a list of possible submission methods in order of most preferable to
least preferable:
1) Internet e-mail to Robert Wong (rwong@direct.ca).
All e-mail submissions received via the Internet will be acknowledged by a
reply. Some acknowledgements may take a while, depending on the complexity
of the submission.
2) FidoNet e-mail to Robert Wong Jr. (1:153/290)
This BBS is called Frog Hollow BBS and is in Port Moody, BC, CANADA.
3) Regular postal mail to Robert Wong Jr., 1921 East 61st Avenue, Vancouver,
B.C., CANADA, V5P 2K2.
4) Voice at (604) 322-6918 (H).
There should either be a live person at this number, or a functional
answering machine. Ask for Robert Jr.
5) Any other method not listed above. Yelling across a busy street may be
acceptable. Carrier pigeon however, is not an acceptable method. :-)
--------------------------------------------------------------------------------
The format of a submission
--------------------------------------------------------------------------------
Submission of information should hopefully be in a readable form of English.
:-) It should also be understood by a non-programmer (me!).
Upon request, your company affilitation will be included. Thus every
time your e-mail address is mentioned, your company affilitation will also
be mentioned. (eg. Joe NeXT (jn@JoePizza.com) [Pizza Products Inc.])
For the submission of product info, the format shown below would be much
appreciated:
ProductName v.version number, software type
Short description of product. 3-5 lines.
Address of company
Postal Code
Time time zone
Voice: (xxx)yyy-zzzz
Fax: (xxx)yyy-zzzz
BBS: (xxx)yyy-zzzz
E-mail: Joe NeXT (jn@JoePizza.com)
Cost: $ and currency type
Basically, the Keeper of the ZyXEL FAQ is lazy! A submission of product info,
and/or modem vendor info would ideally be a matter of cut'n paste into the
FAQ.
***begin soapbox/comments/questions/requests/hot news/misc***
This is my first crack at doing a FAQ. Please be patient. Any errors,
either in technical content or English usage (Gasp!) are entirely mine.
Please e-mail me any corrections.
The new Elite models are now shipping! The upgrade prices have dropped,
and now there is the new Omni 28.8 models!
There has been a some changes to the FAQ as a result of the new modems.
Some entries have been added/changed/deleted/etc. Hopefully there are
no numbering mistakes, or references to non-existant questions. Eventually
each question will have an entry that says "Applicable for XXXX model".
Please note my new e-mail address rwong@direct.ca The old address,
wrob@unixg.ubc.ca will still be valid for a few months.
Many thanks to all the submitters and ZyXEL USA for supporting this FAQ.
A special hello is given to Jussi Torhonen in Scandinavia. He was kind
enough (and persevering enough) to repost the FAQ to Fidonet in more than
30+ pieces.

Subject: Q.1 What is the proper pronunciation of "ZyXEL"?
--------------------------------------------------------------------------------
The proper pronunciation of "ZyXEL" is apparently "Zai-sell". Note the "Zai"
rhymes with "buy".
--------------------------------------------------------------------------------
Subject: Q.2 What is a "ZyXEL"?
--------------------------------------------------------------------------------
ZyXEL is the name of a modem manufacturer. Thus a "ZyXEL" is a brand of
modem. They manufacture a series of fast, feature-packed faxmodems that
operate on multiple platforms. The following chart will serve to quickly
explain the product line:
Model Type Display Data Speed

Notes: 1) The U-1496, aka the U-1496S is no longer manufactured.
2) Aside from nomenclature, the U-1496 is *exactly* the same as the
U-1496S; the U-1496+ is *exactly* the same as the U-1496S+.
3) U-1496S/S+ models with ROMs v6.00 ROMs or newer can have a
display screen that shows the lights that are on the E but not
the S. Each "light" is depicted with a rectangular box and a
corresponding short label.
4) Rackmount modems require in addition, a RS-1600 Rack Mount System
and Network Management Software (NMS).
5) All modems now ship with 14.4 ZyCellular capability.
For further information about ZyXEL modems, contact your local authorized
reseller, or mail server (c.f. I.2).
--------------------------------------------------------------------------------
Subject: Q.3 What are the new modems called?
--------------------------------------------------------------------------------
The new modems are called the the Omni 288 series, Elite 2864 series
and the Supreme 2864 series. The Omni series are the "value-priced line",
non-ISDN upgradeable line. The Elite models will have LEDs for display and
the Supreme models will have a LCD for display. Currently, that is the only
difference between the Elite and Supreme models.
Model Names:
Omni 288S LED display, V.34, serial port only
Omni 288P LED display, V.34, parallel port w/slow aux. serial port
Elite 2864 21 LED display, V.34, 2 wire dialup/leased line, ISDN
upgradeable
Elite 2864L 21 LED display, V.34, 2/4 wire leased line, ISDN
upgradeable
Elite 2864I (S/T) 21 LED display, V.34, ISDN capable (S/T interface)
Elite 2864I (U) 21 LED display, V.34, ISDN capable (U interface)
Supreme 2864L 20*2 LCD/10 LED display, 2/4 wire leased line, V.34,
ISDN upgradeable
Supreme 2864I 20*2 LCD/10 LED display, V.34, ISDN equipped
--------------------------------------------------------------------------------
Subject: Q.4 What distinguishes ZyXELs from other modems?
--------------------------------------------------------------------------------
***** WARNING: Market-speak, Sales pitch *****
ZyXEL makes good, fast, and reliable modems. Instead of using generic
chipsets to produce modems, ZyXEL uses Texas Instrument Digital Signal
Processors (DSPs) in their modems. This design allows new features and
bug fixes to be implemented in a simple manner.
It has a whole plethora of features:
. ZyX 16.8, ZyX 19.2 kbps(on Plus models) data transmission speeds
. V.32 (9.6 kbps), V.32bis (14.4 kbps) data transmission speeds
. V.17 (14.4 kbps) fax transmission speeds
. Automatic speed fall-back and fall-forward
. V.42bis data compression
. sending and receiving fascimiles
. voice recording and playback
. CallerID support
. Distinctive Ring and Extended Distinctive Ring support
. Remote configuration
. Call-back security
. etc, etc, etc.
***** End Warning *****
Reality: ZyXEL makes a very good modem. Bugs are fixed in a prompt manner.
Features are also added in a regular basis.
There are some deficiencies in the product.
. The documentation is too technical at times, as well it has some
English errors. Currently it is being re-written in the form of
both a user and a technical reference manual. The new manual will
hopefully solve this shortcoming.
. Bugs! (At least they are acknowledged!)
--------------------------------------------------------------------------------
Subject: Q.5 What features will be in the next generation ZyXEL modems?
--------------------------------------------------------------------------------
The new ZyXEL modems are not intended to be just a ZyXEL with a faster
protocol. They are intended to be a new GENERATION of ZyXEL modems. As
such, they will have some additional features. There seem to be two at
least two new models -- a V.34 model and a ISDN upgrade for the V.34
models. Currently, the feature set of the new modems appear to be:
1] ZyXEL V.34 Modem

* ISDN Upgradable (option for Elite series)
2] ZyXEL ISDN Modem - A Seamless Transfer from PSTN to ISDN
========================================================
The ZyXEL ISDN Modem sets new standards in performance and usability
for ISDN applications. This universal communication platform supports
the most highly integrated services over ISDN lines without
sacrificing connectivity to today's more prevalent analog lines. It
is backward compatible with PSTN and includes most of the fine
features found in other ZyXEL fax/modems including V.34. The modem
works with most existing communication software using existing ZyXEL
AT commands. It also fully supports the current standard ISDN
application interface, COMMON-ISDN-API versions 1.1a and 2.0. You can
run all of today's commercially available ISDN applications.
Upgrading to the ZyXEL ISDN Modem maintains your link to the analog
world and prepares you for the digital world of tomorrow - today.
The modem firmware handles both D and B Channels protocols. For
D-Channel, it supports EDSS1, 1TR6 and NI1/NI2; for B-Channel, X.75
SLP, V.120, V.110, and Bundle(128Kbps). Better yet, the modem is
ready for new developments. It has a 8 Mbit flash EPROM that allows
you to conveniently download and program the modem with new
protocols using a PC.
A special compression engine supports V.42bis compression on the
B-Channel at full speed over ISDN lines. Applied with X.75, V.120, or
the Bundle protocols, this translates to up to a half-megabits per
second transfer rate. (That's almost 4-Megabytes per minute!)
The ISDN Modem has a full feature A/B adapter (analog port) that
recognizes standard DTMF tones and generates a standard ring signal
to the connected device. It also generates metering pulses (16KHz for
Germany and 12KHz for Switzerland) according to the Charging
Information it receives. If you want, you can use one B-Channel for
voice communications while sending data over the ISDN through the
other.
The key features of the ZyXEL ISDN Modem are:
* Full compatibility with both ISDN and PSTN
* Two application program interfaces:
. ZyXEL ISDN AT Commands
. CAPI 1.1a and 2.0
* Supports AT&T 5ESS, NT DMS100 D-Channel protocols (N. American models)
* Supports 1TR6 and EDSS1 D-Channel protocols (European models)
* Supports X.75, V.110, V.120 and Bundle(128Kbps) B-Channel protocols
* Easy upgrade path using flash EPROM memory
* V.42bis data compression using the X.75,V.120 and Bundle B-Channel
protocols.
* High speed serial/parallel DTE interface
* Full-feature A/B adapter
* Digitized voice capability
* Asych to sych PPP support
* Data encryption via DES
* Embedded protocol analyser with color(ANSI) display
* Supports NetWare CAPI Manager
* 8-MB DRAM for on-board fax receiving (optional)
Release of the rackmount versions will follow after the standalone versions.

Subject: Q.6 What is the availability of V.34 ZyXEL modems?
--------------------------------------------------------------------------------
The Elite 2686 models and the Omni 288 models are now shipping.
The Supreme models are scheduled for release in 06/96. No word is available
concerning the pricing for the Supreme models.
No word
is available concerning the pricing and availability of the, internal,
rackmount, or models.
However, an internal model
(for IBM computers) may be planned. The internal model (if produced) would
ship after the release of the Supreme models.
A portable model is not currently planned.
--------------------------------------------------------------------------------
Subject: Q.7 What is the difference between the Omni and Elite series?
--------------------------------------------------------------------------------
Essentially the Omni has most the features (voice, fax, modem, etc..) of the
Elite series. However, there are some important differences. The Omnis:
1) are not ISDN capable/upgradeable
2) are available in *EITHER* serial or parallel versions. The serial versions
do not have a parallel port. Parallel versions have the parallel port as
well as a slow auxiliary serial port (max DTE speed 38.4 kbps). The aux
serial port is for management/initial configuration.
4) do NOT have the 8MB DRAM capability
5) have 4Mbit Flash EEPROMS rather than 8Mbit
6) are physically/cosmetically different
--------------------------------------------------------------------------------
Subject: Q.8 What are the advantages of buying an Elite?
--------------------------------------------------------------------------------
<begin sales pitch>
Because you can have
ISDN *and*
V.34 *and*
fax (both G3 and the analog stuff) *and*

<end sales pitch>
--------------------------------------------------------------------------------
Subject: Q.9 What options are available for the Elite series?
--------------------------------------------------------------------------------
When customers buy the the Elite 2864 series modem, they can buy additional
options for the modem. These options can be:
1) the analog module for V.34 connections on analog/POTS lines.
2) the leased line module for 4 wire leased line connections.
3) the ISDN module for ISDN connections.
--------------------------------------------------------------------------------
Subject: Q.10 What is the difference between the "Plus" and the regular
models?
--------------------------------------------------------------------------------
Paraphrased and modified from the page 1-1 of the ZyXEL User's Manual
(Revision 2.1). [page 1-1 in the on-line version]:
The U-1496 "Plus" models have a faster processor and more memory. This
allows the "Plus" models to have:
. faster speeds ZyXEL specific 19.2 kpbs (between two "Plus" modems)
. external "Plus" models support a 76.8kbps DTE rate (recent external
non-"Plus" modems apparently also support the higher 76.8kbps DTE rate)
The basic feature, function, and operation of the "Plus" versions are the
same as the normal non-"Plus" versions.
Brent Mosbrook (brentm@zyxel.com) [ZyXEL USA] explains that in the future,
the Plus models will have 2 Mbit ROMs to allow room for "future enhancements".
--------------------------------------------------------------------------------
Subject: Q.11 What features does the U-1496S+ (aka U-1496+) offer?
--------------------------------------------------------------------------------
The U-1496S+ (aka U-1496+) is ZyXEL's flagship modem. It is an external modem
with a display consisting of six (6) LED lights and a two (2) line by twenty
(20) character backlit LCD display.
In addition to the usual features found in U-1496 "Plus" models (ZyXEL-
specific 19.2 kbps speed and 76.8kbps DTE rate) the U-1496S+ has the
following features:
. two (2) or four (4) wire leased line capability
. V.33, V.29, V.27ter protocols
. dial backup capability (calls backup phone number when leased line is
unavailable.)
. on-line conditioning monitoring [LCD display shows link option (eg.,
V.32bis), line speed, error control, data compression, line type (eg.,
dial-up), data format (eg., asynchronous), instant transmission throughput,
signal to noise ratio, receiving signal level, phase jitter in received
signal, frequency offset, retrains granted, retrains requested, round trip
echo delay and carrier loss counts.]
. capability to view the above parameters and the capability to change modem
settings via four (4) arrow keys on the front panel.
--------------------------------------------------------------------------------
Subject: Q.12 How fast do ZyXELs communicate with other ZyXELs and other
modems?
--------------------------------------------------------------------------------
Between two ZyXELs:
ZyXEL modems will communicate with each other at the highest speed that is
common to both modems. This means that the "Plus" (U-1496 B+/E+/S+) and
rackmount models will communicate with each other at the ZyXEL-specific speed
of 19.2 kbps. Non-"Plus" models communicate with each other and with "Plus"/
rackmounts at the ZyXEL-specific speed of 16.8 kbps. Note that both the
19.2 and the 16.8 kbps speeds are full duplex protocols.
The ZyCellular option is available on ALL ZyXEL modems, and is now capable
of 14.4 connects using the ZyXEL-specific CELL 14.4 protocol. Again, both
modems must have the ZyCellular option in order to use the CELL 14.4 protocol.
Between a ZyXEL and a non-ZyXEL modem:
The fastest speed that ZyXEL modems will communicate with non-ZyXEL modems
is at 14.4 kbps (V.32bis).
The fastest speed that ZyXEL modems will communicate with V.32terbo modems is
at 14.4 kbps (V.32bis). V.32terbo modems do run at 19.2 kpbs. The modulation
scheme of V.32terbo modems are separate and distinctly different from the
ZyXEL 19.2 kbps implementation. Thus V.32terbo modems are *NOT* compatible
with ZyXEL modems at either the ZyXEL-specific speeds of 16.8 kbps or 19.2
kbps. (Brent Mosbrook (brentm@zyxel.com) of ZyXEL USA explained that a
different bit mapping scheme was used in each modem.)
The fastest speed that ZyXEL modems will communicate with USR HST/VHST modems
is at 2400 baud. ZyXELs will communicate with a USR Dual Standard (DS) modem
at 14.4 kbps (V.32bis).
The fastest speed that ZyXEL modems will communicate with V.FC (V.Fast Class)
modems is at 14.4 kbps (V.32bis).

[This was originally posted by Brent Mosbrook (brentm@zyxel.com) of ZyXEL
USA technical support. It was slightly modified by me (rwong@direct.ca).]
The following information summarizes the various methods of accessing ZyXEL
technical support.
BBS We operate a 4-node BBS, 24 hrs a day. This provides ZyXEL
users access to the latest rom binaries, Zfax updates,
configuration guidelines, and software setup instructions.
In addition, sysop pricing and order forms are available.
You can reach the BBS by dialing 714-693-0762
Internet The site called zyxel.com has been established. Please use the
following email addresses:
sales@zyxel.com For information regarding pricing,
availability, literature, upgrades, and sysop
deals.
tech@zyxel.com For installation problems, configuration
questions, and general technical information.
bug-report@zyxel.com For submission of bug reports (currently used
for BETA versions of Zfax 3.0x).
The comp.dcom.modems and comp.dcom.fax newsgroups are also
monitored, and posts/replies to the newsgroups will be made when
appropriate.
An anonymous FTP site has also been established at ftp.zyxel.com
(aka ftp.sdsc.edu). ZyXEL related files are in the
/pub/other/zyxel directory. The latest official roms and software
here will be posted to this site. However, the FTP is not intended
to replace the BBS, which has a much wider array of available files.
Fidonet We maintain a node on the network, which is linked to our
BBS. You can reach us at: 1:103/725 (1:202/701.101

--------------------------------------------------------------------------------
Subject: Q.15 What are the prices for upgrading a ZyXEL?
--------------------------------------------------------------------------------
Firmware upgrades are available for free via anonymous FTP to sites
carrying ZyXEL ROM images. U1496 users, however still need to provide their
own EPROMs, EPROM burners, EPROM erasers, etc.
ZyXEL USA is offering to upgrade U-1496E models to U-1496E+ models for
US$150 (plus shipping). Upgrading your U-1496E to a U-1496E+ by this
method will ensure that your warranty remains valid.
There are reports that a U-1496E can be upgraded by users to a U-1496E+
for substantially less. This "do-it-yourself" method seems to work.
It would also void your warranty.
ZyXEL is now shipping the new Elite 2864 and the Omni 288 modems. The
offer from ZyXEL USA to upgrade to the new Elite and Omni modems expired
on September 30, 1995. Contact your local dealer for more info.
The new Supreme series is currently in beta testing and *not* shipping.
The ETA for the Supreme series is 06/96. When the Supreme models
are shipping, U-1496S/S+ users will be offered an upgrade.
--------------------------------------------------------------------------------
Subject: Q.16 Why don't dealers sell the V.34 upgrades?
--------------------------------------------------------------------------------
Brent Mosbrook (brentm@zyxel.com) [ZyXEL USA] writes:
I don't think any of the dealers would want to offer the upgrade, since there
would be a 0% margin in it for them.. they would lose money.
--------------------------------------------------------------------------------
Subject: Q.17 What is the warranty on a ZyXEL?
--------------------------------------------------------------------------------
All ZyXELs come with a two year parts and labour warranty. ZyXEL USA has
decided to extend the warranty an extra three years. Thus a ZyXEL USA
modem has a five year parts and labour warranty.
This warranty allows the user to install and change the ROMs on the modem.
Other hardware modifications such as the upgrading of the ROM socket,
the installation of a capacitor for Caller-ID, and other modifications
that ZyXEL USA performs MAY keep the warranty intact. The basic
philosophy regarding user-modifications seems to be that as long as
the modification is PROPERLY performed, the warranty will be honoured.
(Burn marks, large holes, etc., would likely void the warranty.)
Specific questions regarding hardware modifications and the effects to
the warranty should be e-mailed directly to ZyXEL USA.

Subject: T. Technical Frequently Asked Questions
================================================================================
Subject: T.1 What is the latest official ROM release(s)?
--------------------------------------------------------------------------------
1.04 For Elite 2864 model
1.09 For Elite 2864I model
6.15 For U-1496 modems with 1-Mbit EPROMs
5.05c For really old non-U-1496plus models
with 1-Mbit and 512-Kbit EPROMs
6.23 For U-1496P (portable) model
The ROM release previous to the 6.15 was version 6.14. The latest quick
reference card and the release notes for the latest ROMs can be obtained
via anonymous FTP from the Taiwan or USA FTP sites.
When a new official ROM revision is released, it is available for *ALL* ZyXEL
modems. Thus when the 6.14 ROMs were released for the U-1494E modems, it
was also available for the E+/B/B+/S/S+ modems (and other ZyXEL models).
Beta ROMs have been known to ship in modems supplied by ZyXEL USA, so you
may have a newer version than those listed here.
--------------------------------------------------------------------------------
Subject: T.1A How does one determine the ROM revision?
--------------------------------------------------------------------------------
For all ZyXEL modems: Type "ATI" in a terminal program. If the response is
"1496", then type "ATI1" in the terminal program. (Alternatively,
U-1496/U-1496S or U-1496+/U-1496S+ models can display the ROM revision via
the product information screen.)
Paul Platt (pep@cypress.com) writes:
There is an easier way to get the firmware revision if you have an S or
S+ model ZyXEL. Select the diagnostic display screen. Move all the way
right. The firmware revision will show on the display. Note that you
cannot always trust the corner arrow markers. They sometimes indicate
that there is no "next screen" when a "next screen" actually exists.
At some point, the response should have something like "U1496E V 6.13 M".
The "V 6.13" indicates the ROM revision number (i.e. Version 6.13)
The "M" character at the end indicates 1Mbit ROMs.
The "K" character at the end indicates 512kbit ROMs.
The "P" character at the end indicates that the modem is a "Plus" modem.
--------------------------------------------------------------------------------
Subject: T.1B What does one do if one does not have have the latest ROMs?
--------------------------------------------------------------------------------
The most convenient way to get the latest ROMS is to buy them. OCOMP, The
Questor Project, ZyXEL USA (US$35), and others sell EPROMS with the latest
EPROM release (cf P.9 or T.1.C).
Another way to get the latest ROMS is to "make" a set. First, obtain two
EPROMs (cf T.1C). Then, FTP the latest ROM image from a FTP site. (A
complete ROM image consists of a pair of files. There is a pair of files for
each of the E/E+/B/B+/S/S+ models.) Next, erase the EPROMs with an EPROM
eraser (UV-light), verify the EPROM has been completely erased, and then use
an EPROM burner to burn in the latest ROMs (cf T.1.D).
Incorrectly programmed EPROMS will not work. The modem will compare the
checksum of the chips with the checksum reported i the ATI1 command. If
they are different, the modem will not function.
Hint: Having two sets of ROMs around is a GREAT idea. Keep the old set that
was in the modem, and install the latest ROMs. If a bug is found in the new
ROMs, the old set can be re-installed. If the new ROMs are OK, then the old
set can be erased, and reused to burn in the next ROM release.
--------------------------------------------------------------------------------
Subject: T.1C Where does one obtain EPROMs to update modem ROMs?
--------------------------------------------------------------------------------
Almost any major electronics supplier should be able to get the needed parts.
You'll also need access to an (E)PROM burner capable of burning 1-Mbit EPROMs.
Shop around for your EPROMs, as prices can vary drastically. ZyXEL does sell
EPROMs for use in its modems.
You need **TWO** EPROMs for a complete set of ROMs.
***BUY TWO EPROM CHIPS***
NOTE: Radio Shack doesn't count as a major electronics dealer.
Part number to get:
27C010 1-Mbit EPROM
27C512 512-Kbit EPROM (really old non-plus's)
Speed (of EPROMs) to get:
|------------------------------------------|
| non-plus models | plus models |
|----------------------------------------------------------|
| 512 kbit | 150 ns or faster | 100 ns required |
|----------------------------------------------------------|
| 1 Mbit | 150 ns or faster, | 100 ns required |
| | 120 ns recommended | |

John Weidman (dk139@cleveland.Freenet.Edu) has bought the 100ns EPROMs (part
number TMS27C010A-10JL) from Newark Electronics (1-800-367-3573 in the US and
Canada).
Ackers Mattias (d2matac@dtek.chalmers.se) has used "ST M27C1001" Signetics
Thomson (??) 100nS EPROMs and they work fine with his E+ modem.
Andrew Jackson (jackson@stc.nato.int) has also used SGS-Thomson 27C1001 EPROMs.
They work. In his experience, (but not confirmed) these devices apparently do
not require the external links from Vcc to pin 1. They cost about NLG 18 each
(about $9US) around September 1993.
David Bowerman (1:153/290) [Fidonet] has used the Macronix 27C1000 and
AMD AM27C010 parts as well with no problems being reported. You do have
to be careful though since the part numbers for that size of EPROMs are a
regular dog's breakfast. One company's 27C010 is another's 27C1000 and
yet another's 27C1001 -- double check the cross references and make sure
that the chip doesn't need the Vpp pin to be tied to Vcc (+5V) during
normal operation. The ZyXEL modems don't even have a pin in the socket
at that pin (1) -- a workaround is to solder a 22K resistor from pin 1
to pin 32. This allows the pin to be pulled high but doesn't allow
enough current to flow during programming to cause problems -- at least
the programmer I'm using doesn't seem to mind.
Note for the inexperienced:
Using faster ROMs will not make your modem go faster. The speeds
recommended are those found to provide good reliability and
operation and getting faster ones will not provide any further
speed enhancement.
Note for the lazy:
Robert McKeever (mckeeveb@sfu.ca) has purchased a large quantity
of 27C010's and would be willing to sell some at a reasonable price

Subject: T.1Ci Will Toshiba EPROMs work?
--------------------------------------------------------------------------------
Dave Platt (dplatt@ntg.com) mentioned that although the Toshiba EPROMs are
compatible with the EPROMs used in the ZyXEL in _most_ ways, and would work
properly in _most_ circuits. Toshiba EPROMs are not 100% pin-compatible and
won't work in the modem without a small hardware modification.
To modify the Toshiba EPROMs to work in ZyXEL modems, Peter Nitezki
(Nitezki@NiDat.sub.org) wrote:
The behaviour of Toshiba EPROMs is well known. They differ from Texas
chips slightly, but the way ZyXEL uses them it's crucial. Toshiba chips
(and many other) require Vpp to be at Vcc during normal operation. But
ZyXEL leaves this pin open (no connector in the socket) as Texas chips
don't need this. The solution is to solder a bridge from Vpp to Vcc pin,
that has to be removed every time you want to program the chip.
(IMPORTANT!!! Leaving the bridge in could damage the programmer circuit!)

Subject: T.1D What format are the ROM images?
--------------------------------------------------------------------------------
Doug Kushner (71024.1643@CompuServe.COM) writes:
ZyXEL EPROM images are in a binary format. However, if using a programming
setup that supports multiple flavors of "binary", such as Data I/O's Promlink

Soenke Behrens (behrenss@Informatik.TU-Muenchen.DE) and Brent Mosbrook
(brentm@zyxel.com) [ZyXEL USA] explain that the ROMs are in binary format.
They also mention that on most burners, you just load the file, identify it
as a binary file, and specify the starting address of 0.
David Bowerman (1:153/290) [Fidonet] mentions: Verify the EPROM against the

Alan Brown (alan@papaioea.manawatu.gen.nz) writes:
If an eprom fails verification, it should be placed under a standard

--------------------------------------------------------------------------------
Subject: T.1E What does one do with the latest ROMs?
--------------------------------------------------------------------------------
Do an "AT &V" and an "AT &Z?" in the terminal program. This will show
the current active configuration settings on your modem. Print out this
display. The information will prove to be handy should something go wrong, or
should you decide to perform a hardware reset.
Install them! Instructions are listed on page 15-16 and 15-17 of the ZyXEL
User's Manual (Revision 2.1). [page 15-7 and 15-8 in the on-line version]
Ensure that each ROM is inserted in the corresponding labelled socket.
Jussi Torhonen (jussi.torhonen@kone.com) talked to the local distributor who
suggested that a hardware reset is advisable at this point. The hardware
reset procedure is listed on page 15-15 and 15-16 of the ZyXEL User's Manual
(Revision 2.1). [page 15-7 in the on-line version] The reset allows setup
of the memory area reserved for new extended S-registers.
The hardware reset will restore the factory default settings (but not the
country code settings). To terminate the continuous analog loop test (the
final phase of the hardware reset) momentarily depress the DATA/VOICE button
on E/E+ models or use the front panel on S/S+ models.
Barney Campbell (bkc@maths.grace.cri.nz) notes that because the modem's
default is set to a DTE speed of 38.4kbps unless the terminal is pre-set to
that speed, the hardware test result will appear as garbage on the screen,
because normally the DTE speed is detected by receiving an AT. However
a test result is still "available" from the LEDs (U1496E/E+).
To restore the modem to the settings before the hardware reset, re-input the
results of the "AT &V" command.
Barney Campbell (bkc@maths.grace.cri.nz) notes that the stored phone numbers
in the modem are also deleted in the hardware reset. To restore the modem to
the settings before the hardware reset, re-input the results of the "AT &Z?"
command.
--------------------------------------------------------------------------------
Subject: T.2 In which countries are ZyXEL modems certified to operate?
--------------------------------------------------------------------------------
Every country has telecommunication laws that prohibit the connection of
unapproved telecommunication devices, including modems to the phone line.
Approval by a country's telecommunications regulatory agency may entail
hardware/firmware modifications to the modem in order to comply with
telecommunication laws. This could include modifications for radio-frequency
interference, pulse dial make/break ratios, redial capabilities, etc.
The words "approved for use in country XYZ" mean that the modem *ITSELF* has
been modified to comply with the telecommunication laws of that country.
This means that an American FCC approved modem imported to Germany would not
be a legal telecommunications device in Germany. The actual modem was
FCC approved to work in the USA, but not BZT approved to work in Germany.
No one can prevent the above scenario from occurring in any country.
Possession of an unapproved device is usually not illegal. Attachment of the
device, however, usually is illegal. It may result in confiscation of the
device and/or financial penalties. [Non-approved ZyXELs have apparently been
confiscated before in Germany. You are now cognicent of the albeit slim risks.
Don't say that you were not warned.]
[Rob MacKinnon (robmack@bsc.no) adds that is is illegal to import unapproved
telecommunications devices into Norway. Apparently the customs authorities
will send the unapproved device back to the originator if it is found in
the mail. If you happen to own an unapproved device, the state acting on
behalf of Norske Telecom has the right to enter your house and confiscate
the device because it is illegal to own one in Norway, not just use one.]
[Tor Rune Skoglund (torrunes@idt.unit.no) adds:
It is in fact illegal to IMPORT, SELL and USE non-certified modems here
[in Norway]. Usually, the customs just skim through the invoice to see if there
any word thats looks like "modem", and then they will refuse to deliver it.]
Aside from the possible legal problems due to using an unapproved device, there
are also some practical problems. Each ZyXEL modem operating its approved
country has certain hardware modifications. These allow the modem to function
better in the telecommunications environment for which it was approved. For
example: German ZyXELs have a filter that eliminates the German cost-counting
impulses. Polish ZyXELs have a reduced ring detector sensitivity that
prevents voltage spikes from accidentally activating the modem.
Should problems be encountered using an unapproved/uncertified ZyXEL modem,
finding help may be difficult. The local vendor/distributor would be
reluctant to help, as the product was not purchased from them. The original
vendor/distributor might be difficult to reach. ZyXEL Inc. itself may not
be too forthcoming, as product support costs are shifted to the parent
company AND it encourages distributors to export product into another
distributor's market (distributor turf-wars).
Thus a ZyXEL modem operating in the country (for which it was approved) will
work better than than an unapproved/uncertified ZyXEL modem. (Of course,
your milage may vary.)
Below is a list of countries in which ZyXEL modems have been approved for use.
This list is *NOT* complete, nor exhaustive. If your country is not listed in
this section, your modem may be approved for use in your country. This list is
by no means definitive.
Australia, AUSTEL approved
Austria, OePTV (Oesterreichische Post- und Telegraphenverwaltung)
Klaus J. Rusch (k.rusch@ieee.org) writes:
OePTV has approved the 1496E(+) ZyXEL modems, suffixed with the letter
'A' for Austria, for use as data modems. Fax and voice capabilities,
as well as fax/data detection, are available yet not approved in the
Austria models. The modems come with 3 meter TDO cables, ZFAX software
and 220 V 50 Hz power supplies.
Similar to Germany's 1496EG(+), the 1496EA(+) must establish a connection
within twelve tries. Failure to do so causes the modem to block, and
require a manual reset (power off/on). Any request to connect (ATD)
is answered with 'STOP !'. Note: Setting the country code to 233
has the same effect with the 1496E+ model.
Czech Republic, Czech Telecom

Germany, (BZT)
Eelco H. Essenberg (essenber@dutiws.twi.tudelft.nl) writes:
I just read the september issue of the German computer magazine c't.
It appears ZyXEL has obtained BZT certification for a model called
"U-1496EG Plus". This basically is the E+ with a metal housing.
Pulses for pulse-dialing are no longer generated by a relays, but
electronically. A filter eliminates the german cost-counting impulses.
Automated redialing has been changed (suppressed) according to german
telecom rules.
[Minimum time between 1st and 2nd try: 5secs;
" " " 2nd " 3rd try: 60secs;
No more than 12 tries to the same number if no answering tone is
received;
After 12 failed tries, a minimum waiting time of 1 hour before attempting
the same number.]
Sufficient changes have been made so that this beast will only accept ROM
updates specially designed for it: no chance of reversing the redial disability
this way :-(. Also, the second RJ11 jack, the one in which you connect your
phone, has been removed. Worst: while the normal E+ costs around DM900, this
thing is expected to cost close to DM1400.
In Germany one can buy the 1496EG+, the telecom-certified version of the 1496E+
which has some diffences to the original 1496E:
*The case is metallic
*There is a mechanism implemented which delays and stops redialing after
several unsuccessful dials.
*ROM-Updates are allowed, but only with certified releases.
*Impulse-dialing is _much_ more silent
*It's much more expensive (around 1350.- DM)

In New Zealand, a "Telepermit" is issued to the *importer*. If another importer
decides to start carrying an item, even if it's factory modified for NZ, it must
be resubmitted by the new importer.
On the flipside, "Telepermits" are cheap - NZ$2000 (~US$1050) and include all
laboratory test costs.
Poland, Ministry of Communications
U-1496E, Polish homologation certificate no. 421/93
U-1496S+, Polish homologation certificate no. 513/93
ZyXEL is probably the only, reasonably priced modem capable of coping with
the mediocre Polish telephone lines. That comes with a price, however.
ZyXEL modems sold in Poland are a bit different than FCC version, and of
course more expensive.
Changes:
1) Reduced sensitivity of ringer detector, so no accidental spikes in
telephone lines will activate the modem.
2) Higher input impedance, as required by the telecommunications regulations.
3) Considerably higher DTMF level (than in the FCC model).
While the third modification is relatively easy to implement, through the
replacement of the ROM(s), the other two require significant hardware
change. Scientific [a Polish dealer of ZyXEL and Zoom modems] is authorized
by ZyXEL to make such changes, including ROMs replacement as well.

Subject: T.3 What are known country codes?
--------------------------------------------------------------------------------
Country codes customize ZyXEL modems to work better in a particular country.
A ZyXEL modem operating in the country for which it was approved for use,
should leave its country code unchanged.
Austria: 233
Australia: 244
Belgium: 248
Czech Republic: 246
Denmark: 252
Finland: 240
Germany: 237
Greece: 247

Poland: 231
Singapore: 241
Slovakia: 228
South Africa: 254
Sweden: 250
Switzerland: 251
United Kingdom: 249
ZyXEL USA does not confirm nor deny the existence of country codes. Thus
they can not confirm if any entry in the above list is correct. [Note that
ZyXEL would get into big trouble with the local telecommunications authority
if people suddenly started to import large numbers of non-approved modems into
the country.]
If you know of any other country codes, please mail them to Robert Wong
(rwong@direct.ca) for inclusion in a future version of this FAQ.
--------------------------------------------------------------------------------
Subject: T.3A How does one change a country code?
--------------------------------------------------------------------------------
To get the current country code (North America = 255), type:
AT#H
Write down this country code, in case the new country code does not work
properly.
Follow these steps to change the line interface to match those
used/required for operation in various countries. Type:
ATS38.1=1
AT#G123 where 123 is the country code desired.
AT&W to save these settings
Probably best to power-cycle the modem at this point.
Again, a ZyXEL modem operating in the country for which it was approved for
use, should leave its country code unchanged. Changing the country code in
a ZyXEL (for use in that specific country) SHOULD theoretically improve its
operation. There have been reports to the contrary. If problems occur from
using a new country code, reverting to the previous country code might be
advised.
--------------------------------------------------------------------------------
Subject: T.4 What kind of power supply is used?
--------------------------------------------------------------------------------
ZyXEL uses a transformer that is a 120V AC, 60Hz, 23.4W model that outputs
20VAC, 900mA with a center tap.
The transformer should ideally have output between 50 Hz and 60 Hz.
+-----+
AC --> | o o | <-- AC
\ o /
---
^
+-- Center tap
Michael Chua Boon Wei (chuabw@singnet.com.sg) has a power supply that is a
240V AC, 50 Hz, 27.5W model that outputs 21V AC, 900 mA. It has the same
pinout as above.
Michael Kuhl (mkuhl@newbridge.com) and Robert Wong (rwong@direct.ca) has a
slightly different power supply that is a 120V AC, 60 Hz, 12.5W model that
outputs 9V AC, 1000mA. It is also described as a Class 2 Transformer,
Part No. 30-111-011496, Model No. A48091000 transformer. Also, the pinout is
slightly different.
+-----+
AC --> | o o | <-- No connection
\ o /
---
^
+-- AC
Alan Brown (alan@papaioea.manawatu.gen.nz) has a power supply (non-ZyXEL)
that is a 230V AC, 50 Hz model that outputs 14V AC. The shape of the
connector is a cylindrical 2.5mm coaxial power socket seen on many other
pieces of electronic equipment.
ZyXEL modems seem to accept many different voltages ranging from 9 to 20V AC.
The output voltage for the transformers may be as low as 5V AC. Also, the
power supply may or may not be center tapped. Also, in countries with
220V AC, the local suppliers supply a locally manufactured power supply.
To avoid any potential problems, use only the power supply that came with the
modem. ZyXEL does sell power supplies for owners should they move to another
country or lose the factory power supply.
Please e-mail Robert Wong (rwong@direct.ca) if you have a different power
supply.
--------------------------------------------------------------------------------
Subject: T.5 Are ZyXEL modems Hayes-compatible?
--------------------------------------------------------------------------------
Yes, ZyXEL modems are Hayes-compatible. ZyXELs use the same basic AT command
set used in the 2400 baud Hayes Smartmodems.
ZyXELs have an enlarged and enhanced AT command set in addition to the basic AT
commands common to the 2400 baud Hayes Smartmodems. These additional commands
deal with higher baud rates, fax settings, voice settings, and other features
that were not present in the original AT command set of 2400 baud Hayes
Smartmodems.
--------------------------------------------------------------------------------
Subject: T.6 How do ZyXEL modems deal with escape sequences?
--------------------------------------------------------------------------------
Byte Magazine, V18, N8, July 1993, pg 184 has a good background article about
escape sequences. The information below is a less technical explanation of
escape sequences.
An escape sequence switches a modem from transmission mode to command mode.
Sometimes, an AT command needs to be issued to the modem when it is on-line
and connected with another modem. Since the modem is on-line, typing an AT
command would send the AT command down the connection to the other modem.
Thus the local modem never receives and acts on the AT command. An escape
sequence is needed to bring the local modem into command mode (without dropping
the connection to the other modem).
One escape sequence is to drop the DTR (Data Terminal Ready) signal on one of
the wires in the serial cable. This is a reliable escape sequence. Some
hardware platforms do not have a wire for the DTR signal and therefore cannot
perform this escape sequence. Another type of escape sequence is needed.
An alternate escape sequence is a pause, followed by three escape characters,
and then another pause. This escape sequence then puts the modem into command
mode, allowing entry of AT commands. (The pauses prevent the modem from
mistaking escape characters in the data stream for "true" escape characters
in an escape sequence.)
Hayes has a patent on the pause, escape characters, and pause technique.
Other modem manufacturers are required to pay royalties to Hayes for use of
its patent. Some modem makers are not using the Hayes patent or any other
method of distinguishing real escape characters. This causes factory
configured modems from these modem manufacturers to inadvertently go into
command mode when the Hayes test file is transmitted.
Taken from Byte Magazine, V18, N8, July 1993, pg 184 without permission:
"Zyxel [sic] has its own algorithm, for which it claims compatibility with
existing code. Since the Zyxel [sic] algorithm is proprietary, we can't
comment on its strength or weakness. However, it caused no problem in our
testing."
Taken from BoardWatch Magazine, V6, N9, November 1992 without permission:
"To illustrate the technical elegance of this [ZyXEL] modem, recall our article
on the Hayes brouhaha over their fixed guard time escape sequence under the
Heatherington 302 patent. Hayes has licensed numerous modem manufacturers to
use this escape sequence. A few have not licensed it and often, their modems
will escape to command mode while transmitting files containing +++ escape
sequences. Hayes caused something of a furor in July by releasing a text
file that if transmitted by many modems that don't use the guard time escape
sequence technique, would abort the transfer and improperly escape to command
mode. Multitech's modems fail the test rather awkwardly. The ZyXEL modem
does NOT license the Hayes escape sequence. According to Gordon Yang, they
use a proprietary variable sampling algorithm that does the job at least as
well. We tried the ZyXEL on the Hayes test file - and sure enough, it worked
like a champ. ZyXEL appears to have engineered a way around the escape
sequence controversy. Yang indicates that they could conceivably publish the
algorithm. If they did, this would take some serious steam out of the Hayes
licensing program."
--------------------------------------------------------------------------------
Subject: T.7 What is the chip set / data pump used in the modems?
--------------------------------------------------------------------------------
ZyXEL models do *NOT* use the Rockwell chipset. ZyXEL uses their own code,
which runs on a Motorola 68000 processor and two Texas Instruments Digital
Signal Processors (DSP). The DSPs used are the same type seen in US Robotics
modems.
Barney Campbell (bkc@tahi.isor.vuw.ac.nz) asks:
"What is the data pump on the ZyXEL modem?
PC magazine 1993 June 29,Vol 12, No 12 p 272 reports that the U-1496S+ uses a
Texas Instruments data pump and that the U-1496E uses a ZyXEL data pump. Is
this correct?
If different data pumps are used in each model, then the S+ might be
OPERATIONALLY different from the E models. Namely, they might perform
differently."
Brent Mosbrook (brentm@zyxel.com) [ZyXEL USA] replied stating that the Texas
Instruments and ZyXEL data pumps behave identically. The DSPs were re-done to
eliminate the daughterboard on some models. The models without the
daughterboard have DSPs which say ZyXEL, while the daughterboard equiped units
say TI. Again, there is no real difference and they behave identically.
--------------------------------------------------------------------------------
Subject: T.7A What is the advantage of this design?
--------------------------------------------------------------------------------
Again, ZyXEL modems do not use a chipset. The main advantage to not using a
chipset is upgradability. New features and bugfixes can be easily "installed"
into the modem.
Kolja Waschk (kawk@Yo.COM) adds:
"Anyone who has an EPROM-burner might download the newest firmware from a ftp
server or public mailbox (many sites available) and put it in his modem. Just
remember, the ZyXEL's haven't been "voice capable" some months ago, but now
they are - without any hardware changes."
Brent Mosbrook (brentm@zyxel.com) [ZyXEL USA] also writes (with a great deal
of marketing-speak):
"The ability to independently design hardware/features is probably
the #1 advantage. We have been able to add many new features
to the basic modem through rom upgrades. (CID, Distinctive ring,
Voice, EDR, etc.)
Also, as shown in the past (E --> E+ upgrade), the modem can be
upgraded by modules. The key components of the modem (CPU, DSP,
ROMS) can be updated/replaced individually. This allows greater
flexibility in adding new hardware capability to existing products.
As stated here in the past by others, a modem vendor who can design
the product from the ground up generally has a higher caliber
engineering dept. They can respond quickly to bug reports, and
have a better understanding of what makes the product tick.
A chipset based vendor is completely dependent upon their source
for most bug fixes, and there is no guarantee that the modem
vendor is capable of implementing the chipset as designed
(even with written instructions from the manufacturer. :))
Bottom line: there is no guarantee that a DSP based modem is any
better than a chipset based modem... The proof is in the end-result.
Take a look at the reviews, and comments of current users to evaluate
a modem.. These should be part of your selection criteria, in addition
to the DSP/Chipset used."
--------------------------------------------------------------------------------
Subject: T.8 What is the meaning of the T401 and T402 timeouts seen in an
"AT I2"?
--------------------------------------------------------------------------------
On page 15-13 of the ZyXEL User's Manual (Revision 2.1), [page 15-6 in the
on-line version] it says that the T401 and T402 timeouts "are normally zero".
Often these values are not zero.
T401 and T402 are the name for two timers that are used in MNP 4 and V.42
connections. The values for both timers are set during the initial handshake.
The T401 is the acknowledgement delay timer that monitors the amount of time
between the sending of a data block and the receiving of an acknowledgement.
The T402 is an inactivity timer which monitors the time between data blocks
sent to the receiver.
The terms "T401 Timeout" and "T402 Timeout" refer to the number of timeouts
in the T401 and the T402 timers, respectively. (A timeout is a "timer
expiration" and is the result of an action not being performed in a given
allotted time.)
Brent Mosbrook (brentm@zyxel.com) [ZyXEL USA] writes:
The "T401 Timeout" indicates the number of resent blocks, due to not
receiving an acknowledgement in the allotted time. The T401 timeout is
just one of the reasons for blocks being resent, so T401 timeouts will not
necessarily be equal to the BLOCKS RESENT value in a link status report.
The "T402 Timeout" indicates the number of frames sent due to inactivity.
These are sent to keep the link active, and assures the other modem that
the connection is still there. This number steadily increases, especially
during a relatively "light" interactive dialup session.

Subject: T.9 What is the selective reject in V.42?
--------------------------------------------------------------------------------
Selective reject is an optional feature of the V.42 error correction protocol.
The v6.10 ROMs were the first ZyXEL ROMs that implemented selective reject.
Brent Mosbrook (brentm@zyxel.com) [ZyXEL USA] writes:
Selective reject is an optional feature of V.42 which allows you to get
higher throughput on noisy lines. The modem sends out blocks, and the
remote side acknowledges after an agreed upon number of blocks (window
size). If one of these blocks is bad, then the modem will only send the
bad one over again, rather than all the blocks (as is the case of other
modems).
The selective reject feature only works when both modems implement it. Thus a
ZyXEL with 6.10 ROMs will not use selective reject connected to a ZyXEL with
6.01 ROMs. When in use, the initial connect string will look somewhat like
"CONNECT 57600/ARQ/V42b/SREJ" (the exact string varies depending on the
AT X[0-7] setting).
Chris Gray (cgra@btma74.nohost.nodomain) explains that selective reject is
an optional part of the LAPM protocol used by V.42 modems. A SREJ frame
requests retransmission of one information frame, having the sequence number
which is cited in the SREJ frame; after this transmission resumes _from
where we left off_. Contrast with ``ordinary'' REJ, which requests
retransmission of _all_ information frames, starting with the one with the
specified sequence number. SREJ is more efficient when just one frame has
got munged.

Subject: T.10 What is the "Capture modem manufacturer information" feature?
--------------------------------------------------------------------------------
ZyXEL modems will capture the name of the remote modem when bit 1 of
S-register 13 is enabled (AT S13.1=1). This information is obtained
during the V.42 handshake sequence. Since the information is an OPTIONAL
feature, it will only work when the remote modem has also implemented this
feature. Some, but not all manufacturers have implemented this feature.
When this information is captured, it is then shown via the ATI2 command,
in the "Last Speed/Protocol" field. The following is an incomplete list
of possible modem manufacturer information:
Information Remote modem type
ZyXEL ZyXEL modem
Flash ZyXEL modem

Subject: T.11 What settings are required to attain the fastest data
connection?
--------------------------------------------------------------------------------
To obtain the fastest data connection for a ZyXEL, a number of steps should be
taken:
a) Lock the serial port speed to the fastest/highest speed supported by the
host computer.
b) Turn off "auto-baud detect", "dial speed-matching", or any similar parameter.
c) Turn on hardware flow control by enabling RTS/CTS flow control in the
communications program.
d) Turn off software flow control by disabling XON/XOFF flow control in the
communications program.
e) Turn off DSR/DTR hardware flow control, as this is used for null modem
connections. (Recommended if the communications program supports this
feature.)
f) External modem owners must use a modem cable that is wired for hardware
flow control.
Notes: 1) Again, the modem cable MUST be wired correctly. Apparently, some
modem cables, even from the factory, are not wired properly for
hardware flow control.
Alan Brown (alan@papaioea.manawatu.gen.nz) adds:
I find that it's generally a good idea to switch the modem to CCITT
DSR (AT &S1), even though no programs I use support this for flow
control.
In CCITT mode, DSR comes up before the CONNECT message (actually as
soon as a link standard is established, even though error correction
may still need to be negotiated), and goes down after NO CARRIER

Subject: T.12 Will V.32terbo be implemented?
---------------------------------------------------------------------------------
ZyXEL USA's response:
V.32terbo is not a CCITT (ITU-TSS) standard, and does not perform as well as
19.2ZYX. We will have to see a greater popularity of V.32terbo to support it.
--------------------------------------------------------------------------------
Subject: T.13 Why Aren't the Elite models upgradeable to V.34+?
--------------------------------------------------------------------------------
No, the Elite models are *NOT* upgradeable to V.34+. V.34+ isn't an
international ITU-TSS standard. Currently, it is a modified version of the
V.34 standard.
Most Elite users would probably like to be able to upgrade their Elite to V.34+
via a simple flash ROM upgrade. Unfortunately, it isn't possible.
Some Elite users are upset about non-V.34+ upgradeability. Please keep a couple
of points in mind:
a) ZyXEL never advertised that the Elite was V.34+ upgradeable. They said that
the Elite was built to take advantage of the new generation of "modem"
technology. i.e. The Elite could be upgraded to faster speeds. ZyXEL meant
upgrading to ISDN, rather than upgrading to V.34+.
[Editor's Note: Unfortunately, many people (myself included) interpreted the
word "upgradeability" the way we want to interpret the it. We read what we
wanted to read and we saw what we wanted to see. Sad, but true. ZyXEL never
promised something (V.34+ upgradeabiltiy) and didn't deliver it.]
b) Since, V.34+ is not a true internationally approved standard, it may be
yet another flash-in-the-pan. ZyXEL did not support V.32turbo, or V.FC. Both
of these were non ITU-TSS approved standards. Users screamed at that time.
Both V.32terbo and V.FC protocols support became non-issues as they were
superceded by the ITU-TSS approved V.34 protocol. Hopefully, V.34+ will die
a quick death.
ZyXEL USA's response:
"ZyXEL Elite Owners
At a time when our competitors were beginning to introduce their V.34
products, ZyXEL was already planning to take our users beyond V.34 into the
unexplored frontiers of ISDN. ZyXEL has always been on the forefront of
technology - and it is not a title we intend to relinquish anytime soon.
Recent inquiries from Elite modem users have brought to our attention some
concerns regarding the 33.6 Kbps speeds available now with some of our
competitors' products. We feel it necessary to inform our users that we do
not have plans to upgrade the Elite Series to 33.6Kbps (V.34+). 33.6K speed
relies heavily on the bandwidth of the telephone carrier which might be hard
to find in the real world phone line.
The Elite 2864 has been designed from the onset as a transitional product
from V.34 to ISDN. We have chosen, in this product, to focus on ISDN because
digital technology is where the modem market is headed. The Elite 2864 was
designed specifically for users who could potentially take advantage of what
ISDN has to offer, but who needed V.34 speeds now.
We have concentrated our hardware development on offering better ISDN
capabilities. As a result we are proud to be able to offer features like
V.42bis Data Compression over ISDN and Channel Bundling - two features which
ZyXEL was one of the first to introduce. Additional enhanced features of the
Elite 2864 set ZyXEL apart - product features like the flexibility provided
by Serial and Parallel ports, the standalone fax feature with direct printing,
DES encryption, Kernel Recovery Mode and larger firmware and DRAM storage space.
We are also planning to support additional popular standards like multi-link
point-to-point(MP) protocol and new Internet communication protocols.
Competition has yet to offer these features in a single device.
As a result of development hurdles, our entry into the V.34 market has taken
longer than expected. But we are moving full speed ahead to improve product
performance and reliability to make up for the lost time. We are confident
that the finished Elite 2864 will be a product to meet all your expectations.
Our mission always has been and always will be to take you to the cutting edge
of technology - not to make quick sales on overnight trends which are here
today and gone tomorrow. As always, we appreciate your continued support of
ZyXEL and your valued feedback. Should you have any concerns about your Elite
2864 modem or have additional questions, please contact us directly at

Subject: T.14 Why Can't the Elite models always connect at 28.8kpbs?
--------------------------------------------------------------------------------
Byte Magazine, V20, N11, pg 40 has an article titled "Telecommunications:
Phone Lines Stymie V.34 Modems. That spiffy new V.34 modem may feel like
a station wagon instead of a turbocharged racer. Here's why." It mentions
that V.34 modems are supposed to communicate at 28.8 kbits/s, however most
people will not get more than 26.4 kbits/s except under prime conditions.
Apparently, equipment used to reduce static, interoffice phone systems,
digital speech compression, etc. reduces the top speed of V.34 modems.
The article makes a couple of negative remarks about early USR Sportsters,
and Rockwell chipset modems. It also mentions that consistent fast data
connections are achieved via ISDN.
Overall, this article is quite informative about the barriers to 28.8 kbits/s
data transmission.
Robert Wong (rwong@direct.ca) writes:
"There was some debate in the comp.dcom.modems newgroup about the connection
speed of the ZyXEL Elite modems. The consensus seemed to be that the ZyXEL
had slower initial connection speeds when compared with the USR modems. Some
posters vehemently stated that the ZyXEL was substandard.
Personally, I have had my ZyXEL Elite for about 1.5 weeks. I have had a grand
total of 64 connections.
3 (4.7%) of the connections were at 28.8
46 (72%) of the connections were at 26.4
15 (23.4%) of the connections were at 23.4
From my very limited experience, I don't often get 28.8 connections. About
70-75% of the time, I get 26.4 connections and about 25-30% of the time, I
get 23.4 connections. Note these are merely *initial* connection speeds.
I have not looked at connection speeds over time. They may have gone up,
stayed the same, or gone down during my connect sessions. I haven't checked,
thus I don't know the answer.
The current v1.04 ROMs are pretty stable. Hopefully in future ROM releases,
ZyXEL can work on increasing and maintaining the initial connect speeds.
ZyXEL has has a pretty good track record for improving their modems. They be
able to address this and other concerns with succeeding ROM releases."
--------------------------------------------------------------------------------
Subject: T.14 Will V.34 fallback speeds be implemented?
--------------------------------------------------------------------------------
The V.34 specification currently calls for fallback speeds of 16.8
and 19.2 kbps. Some people have thus inquired about the possibility of
implementing the 16.8 and 19.2 fallback speeds (in the the current ZyXEL modem
line).
ZyXEL USA's response:
The specifications for V.34 call for a multiple carrier frequency during a
connection ie. multiple baud rates. ZyXELs currently can only do a fixed
baud rate during a connection.
If the specifications are modified to not use shifting baud rates, then it
may be possible.
If the specifications remain unchanged, ZyXEL *MAY* implement V.34 fallback
speeds. If and only if ZyXEL decides to implement the fall back speeds, the
work would BEGIN only *AFTER* the new modems ship.

Subject: T.15 How does one patch GNU NetFax to work properly?
--------------------------------------------------------------------------------
Receiving:
Receiving works flawlessly, PROVIDED that you convince Netfax to send
0x12 instead of 0x11 to the Zyxel when starting to receive a new page.
Apparently the standard changed this over two years ago, and most other
modems still also accept 0x11 as a compatibility kludge.
Sending:
The key to sending multiple pages is to throw out AT+FDT=a,b,c,d and
replace it with AT+FDT, and to set the desired parameters in a
AT+FDCC=a,b,c,d,e,f,g,h message sent when starting up.

Brent Mosbrook (brentm@zyxel.com) [ZyXEL USA] acknowledged the bug and
"we are testing the fix right now, and will release it in approximately a

The problem has apparently been fixed in the v6.11 ROMs. Problems were only

--------------------------------------------------------------------------------
Subject: T.17 Once a fax is received, what does one do?
--------------------------------------------------------------------------------
A fax is received by the ZyXEL modem and fax software. The fax (usually) is
stored as a file on the hard disk in some sort of image format (TIFF, PCX,
etc.). This file is called a "fax image".
The fax software or some other software program can be used to open and
print the fax image.
To put the contents of the fax into a word processor, there are two options:
a) The fax image could just be imported as an image into the document. This
is not a good solution, as the contents of the fax cannot be edited and
the image itself may not be too clear.
b) A better alternative is to use a software package that has an Optical
Character Recognition (OCR) capability. [OCR may be built into the fax
software, or it may be a separate software package. Retrieve the fax file
into the OCR software and use the OCR software to convert the fax IMAGE
into an ASCII file.] Import this new ASCII file into the word processor.
In this manner, the fax image was OCR'ed and is now in a clearer, editable
format on the word processor.
Alan Brown (alan@papaioea.manawatu.gen.nz) adds:
For some reason the PCX images generated by ZFAX 2.xx are not readable by
some graphics packages. DISPLAY, Graphics Workshop (all dos versions) and
VPIC (all versions) definitely refuse to display/edit ZyXEL PCX files.
The author of DISPLAY is apparently looking at the problem.

Subject: T.18 How does enabling callback security affect the reception of

Subject: T.19 What is the easiest way to record voice?
--------------------------------------------------------------------------------
One method of recording voice on a ZyXEL modem is from another phone line.
This method is useful if two phone lines are present.
Another method of recording voice on a ZyXEL modem is to speak into the
*earpiece* of a telephone handset, which is attached to the line connector of
the modem. This technique is may not be too effective.
ZyXEL is now shipping a hardware device/box which will make voice recording
with a ZyXEL much more effective. The modem plugs into the box, and the
phone line is plugged into the box. A switch on the box allows recording
directly from the phone. This box has the amplifiers built in to record
from an un-powered phone. No plug-switching necessary. The ZyVoice box is
now shipping and sells for US$30.00.
Paul Dowling (dowling@fcs260c.ncifcrf.gov) writes:
"I was skeptical to say the least that this solution [the hardware box]
would work. Well, it works MUCH better. I've only played with it for a
few minutes, but there is a definite improvement in the quality. It's
still not as good as I'd like, and there is still a slight whining noise
in the background, but this seems to really have worked.
The switch box includes a power converter and 2 RJ-11 wires. There is a button
next to the dial-up line connection that allows you to select between voice and
normal. The other side has jacks to connect to the phone and wall lines on the
modem and to your telephone. The box is about 3 1/2" x 2 1/2". I don't like
the idea of having an external box and I hope in the future they will build it
into the board, but for now, I'm very pleased with it."

"Horrible is not an objective description [of voice quality]. If you realize

voice quality that compares to that of a radio receiver tuned to a strong
channel, then you will find the voice quality 'horrible'.
Basically, the voice quality (especially ADPCM3) is very good and completely
acceptable for telephone use. As far as the caller is concerned, he won't
know the difference between the ZyXEL's outgoing message voice quality and
that of an answering machine. This is assuming ADPCM3. ADPCM2 and CELP are
significantly deteriorated versions of ADPCM3."

"Rockwell chipsets do higher quality voice replay. This may be due to the fact
that they use a slightly more complicated ADPCM enconding or due to the fact,
that - in addition to ZyXEL modems - Rockwell chipsets are capable of
encoding the signal using 4 bits per sample. However, the RW chipsets do the
sampling at 7200 Hz, the ZyXELs do it at 9600 Hz; that make me believe that
the quality difference depends mostly on the coding algorithm (and tables)
used. On ZyXEL modems, it's nearly impossible to record voice without any
digitally generated background noise; on those Rockwell equipped modems
which I have seen (heard), it IS possible."
--------------------------------------------------------------------------------
Subject: T.20B When will better quality speech at higher encoding rates be
available?
--------------------------------------------------------------------------------
4-bit ADPCM was introduced in 07-05-1994, with v6.13 of the ZyXEL ROMs. The
increased number of bits improves the voice quality noticeably.
Brent Mosbrook (brentm@zyxel.com) [ZyXEL USA] adds:
"Currently, the sample rate is 9600 samples/second. 3-bit ADPCM requires
the DTE speed to be 38.4K."
The new 4-bit ADPCM requires a 57,600 DTE speed.
Question Q.10 mentions that there will be a faster DTE rate in the next
generation of modems. This raises the possibility that even higher
encoding rates may arise in the future.

Subject: T.21 Can a voice call be detected by the modem?
--------------------------------------------------------------------------------
The modem itself cannot distinguish between an incoming fax/data/voice call.
With software, it is possible to discriminate between a fax/data/voice call.
Kolja Waschk (kawk@Yo.COM) [writer of the ZuTSR and ZUtil] writes:
"The modem itself cannot discriminate between a fax/data/voice call. Voice
calls do not differ from normal data calls (assuming most calling modems do
not send a calling tone).
However, the modem can be told to answer in Voice Mode, and then "listen"
what's on the line. It can detect several possibilities, ie. "fax calling
tone heard", "modem calling tone heard" (since firmware 6.11), "DTMF tone
Nr.x heard", and, while in record mode, "caller keeps silent" or "caller
made some noise and then turned silent". It's the software on the computer
that should react differently on these reports and switch the modem into
data/fax mode respectively. Two programs are known to do more : VoiceConnect
and the (not yet released) new ZUtil do real-time signal analysis on the
incoming voice data and can detect - in addition to the above mentioned
events - the presence of "human voice".
The most used method to distinguish between data and voice calls is the
following (flow controlled by the software on the computer)
1. answer the line
2. replay play a spoken greeting message, provoking voice callers to speak
(a small "Hello?" does the job)
3. listen
4. switch to data/fax mode if a calling tone has been received
5. switch to data/fax mode if the caller keeps saying nothing [The call is not
conclusively proven to be a data call, but it is reasonably assume to be a
data call. Ed.]
6a. handle the voice call if "voice" (only with VC or ZUtil) has been
detected or simply the caller does not remain silent and does not
sent calling tones.
6b. handle the voice call if the caller requests it by sending a DTMF
tone, otherwise switch to data/fax mode
As you might see, the spoken greeting message is quite required to provoke a
reaction of voice callers. Because there is no space yet in the modem's RAM
preserved for storing a greeting message, the above method cannot be
automated and done by the modem stand-alone.
This makes it impossible for communications software - which has not been
designed to do so - to distinguish between data and voice calls. (Anyway, for
software like a FidoNet mailer that uses the FOSSIL serial driver, a tricky
TSR utility exists to do the job - ask me, the author ;-)"

cancellation filter in the DTMF detection software in the Elite series.
This filter requires a short probe to determine the channel parameters; it
takes place only once before the first sound is to be played over a phone
connection - thus the "noise".
The result is a very reliable DTMF detection - my modem detects tones
generated by the cheapest DTMF transmitters even while playing music.
(There should be some S-register bit to disable this, but you'll have to
look this up yourself, as it is not in my pre-release manual).
In voice mode, one of the two DSPs is used solely for DTMF detection!"

To enable Caller ID detection by the ZyXEL, type in "ATS40.2=1" in a terminal
program. This procedure was paraphrased from pages 12-5 and 12-6 of the ZyXEL
User's Manual (Revision 2.1). [pages 12-3 and 12-4 in the on-line version]
It should enable Caller ID detection.
Should the above procedure be unsuccessful, then a hardware modification might
be necessary. (c.f. T.26A)

Subject: T.27A What exactly is the hardware modification needed for CID/CND
and EDR?
--------------------------------------------------------------------------------
Brent Mosbrook (brentm@zyxel.com) [ZyXEL USA] writes:
"All new ZyXEL modems have a hardware modification performed at the factory.
A capacitor has been added to filter the Caller ID data.
Current owners can have their modems upgraded by sending the modem back to
ZyXEL, and we will install this capacitor for them. This might not be
necessary, and is only recommended for people who live in an area with CND,
and cannot get it to work.
Any ZyXEL owner can call us and we will help them determine if they have the
capacitor installed."
Brent Mosbrook (brentm@zyxel.com) [ZyXEL USA] writes:
EDR on non-US modems:
It has come to our attention that EDR (included with 6.11a roms) does not work
on modems bought outside the US or Canada. North American modems have a
capacitor installed which is used to filter CID, and other tones received
prior to the modem going off-hook. ZyXEL will not be referencing EDR
capability on any "international" modems sold.
Customers who wish to install this capacitor may do so at their own risk
(local telco regulations may restrict performing this modification).
Due to these possible restrictions, ZyXEL will not be offering a factory
upgrade, but will help customers in identifying 1) whether or not they
currently have the capacitor installed. 2) where the capacitor should be
located.
NOTE: DOING THIS MODIFICATION WILL VOID YOUR WARRANTY, AND MAY VOID THE
LOCAL PTT APPROVAL.
A .033 uF capacitor needs to be installed parallel to resistor R4
(100K ohms), which is located in different places according to the model,
and revision level of your modem. A diagram showing the lastest revision
levels is included to show the general area where R4 can be found. R4 is
generally located near the relays (large yellow, brown or black boxes).
The color code for R4 is brown-black-yellow-gold.(some locally approved
models may have other values. Generally it is between 75K and 150K ohms.)
The capacitor should be non-electrolytic, and rated at 100V or higher.
(these are the latest rev. levels.. older models may differ significantly)

Subject: T.27B What software modifications are needed?
--------------------------------------------------------------------------------
If Caller ID detection is STILL not functional after the hardware modification,
a possible though rarely used solution is to set the timing of certain
registers.
Robert McKeever (mckeeveb@sfu.ca) writes:
Way back in September, ZyXEL released a note (now disappeared off my drives)
which described the use of the S45 and S46 registers to set timing.
They (wrongly) assumed that the ringing on the GTD-5 exchanges was exactly
1.75s, following by 50ms silence, then data; for DMS-100 as a 2s - 3.5s ring
interval, followed by 500ms of silence.
The CallerID length depends on the amount of data the exchange transmits
as its message.
**********************------++++++++++++++++++

Ring Silence CallerID Data
I quote from their message:
<< It is difficult for the modem to receive CallerID signals for both exchanges
without configurable parameters. Two new parameters are implemented for this
purpose, S45 and S46. They are called "guard time" and "silence interval",
respectively.
The silence interval is the consecutive silence that the modem should detect
after ring on before CallerID signal to be processed. Distinctive ringing may
be combined with CallerID, and therefore a guard time is needed for the modem
to inhibit the silence detection.
Registers S45 and S46 are in units of 20ms. Default setttings should be in
the range of S45=100, S46=28 for DMS-100 (Bell, Northern), and possibly
S45=87 and S46=3 for GTD-5 switches. >>
The place this argument falls down, is on the GTD-5 switch, where they
use "flash ringing". Flash ringing starts at any point in the ring cycle,
which means you can get anywhere from 0.1s up to 2.0s of ringing current
before the 50ms silent period followed by data from the central office switch.
In any event, you now have the parameters for the critical registers
for CallerID, for whatever good it may do you.
--------------------------------------------------------------------------------
Subject: T.27C What else do if CID/CND and EDR still doesn't work?
--------------------------------------------------------------------------------
Contact ZyXEL USA with the following information:
1. Make/Model of telco switch serving you.
examples:
AT&T 5ESS
AT&T 1AESS
Northern Telecom DMS-100/200
GTE GTD-5
2. Ring cadence, as measured by AT#B3
(this measures the ON/OFF times for incoming rings)
3. Rom revision level? c.f. T.1.A
4. Is there a capacitor on the R4 resistor? c.f. T.26A
Based on the answers to the above questions, ZyXEL can recommend values
for the registers. ALL of the questions need to be answered to provide
a reasonable response.
--------------------------------------------------------------------------------
Subject: T.28 What changes are needed for overseas calling?
--------------------------------------------------------------------------------
Anees S. Munshi (asm@eecg.toronto.edu) asks:
"While making overseas calls to specfic countries, the current ZyXEL modems
mistake the ringing tone for a busy signal and hangup. While this can be
defeated by setting mode X3 or X1, it is nice to have busy tone detection
on, and disable it only for specific phone numbers."
Try ONE of the changes below to prevent the problem of false busy signals:
. disable busy detection completely with AT X2. This is not a very
good solution, as ALL busy signals are then ignored.
. set Australian short-short ring detection on with S44.7=1. This may
work for the country being called.
. append a ;O (a capital "O") to the end of the phone number.
e.g. ATDT 1234567;O Immediately after dialing the phone number, the
modem goes into command mode and then it goes into an on-line state.

Subject: T.29 What modifications are needed to S/S+ models to get the eye
pattern option?
--------------------------------------------------------------------------------
This modification enables the 3 pins next to the power connector for
the connection of an oscilliscope to view an eye pattern for line diagnostics.
Lars J Poulsen (lars@login.dkuug.dk) wrote:
"The eye pattern is a graphical tool for displaying certain internal
parameters from the digital signal recovery in a V.32(bis) modem.
A table of intermediate results is fed into a pair of digital-to-analog

oscilloscope in X/Y mode. This displays a characteristic pattern of dots
when the modem is trained."
Note: these 2 chips are CMOS devices and are static sensitive. Use
suitable caution.

Paul Cantrell (paul@bosserv.bos.locus.com) called ZyXEL USA to modify his
S/S+ modem to display the eye pattern. Apparently ZyXEL USA no longer does
the modifications any more. The demand for this service was requested so
infrequently that they don't have the traces on the new boards.

Subject: I.5 ZyXEL's CELP compression mode for voice
--------------------------------------------------------------------------------
CELP compression is currently available only on Plus model modems. The
implementation of CELP in the ZyXEL plus model modems is proprietary. As
such, ZyXEL has not published any information regarding the manual decoding/
encoding using this method. ZyXEL also will not confirm nor deny any
sources of information that will will further elucidate the CELP decoding/
encoding algorithms.
A listing of all the US Federal Standard 1016 sources is available by
sending e-mail to Robert Wong (rwong@direct.ca).
The numerous pages of USFS descriptions do not help in decoding ZyXEL's CELP.
They may help to understand what ZyXEL's CELP C code basically does. The
USFS 1016 descriptions are nice to learn about what CELP *could* do ;-)
For further understanding of CELP, it needs a real mathematician and deeper
knowledge of voice processing theories.)
--------------------------------------------------------------------------------
Subject: I.6 What is V.34, and what speeds are supported?
--------------------------------------------------------------------------------
V.34 is a ITU-T (International Telecommunication Union - Telecommunication
standards group) recommendation for 28.8 kbps asynchronous data communication.
V.34 supports 28.8 kbps as the fastest speed. V.34 will also support fallback
speeds (in 2400 bps decrements) down to 2400 bps. Thus V.34 will run at 28.8K,
26.4K, 24K, 21.6K, 19.2K, 16.8K, 14.4K, 12.2K, 9600, 7200, 4800, 2400 bps.
--------------------------------------------------------------------------------
Subject: I.7 What are the advantages to V.34?
--------------------------------------------------------------------------------
Speed! V.34 is a *standard*, ITU-T protocol that specifies a transmission
speed of up to 28.8 kbps. The previous standard speed was V.32bis,
transmitting at 14.4 kbps.
Lawrence Kirby (fred@genesis.demon.co.uk) writes:
In theory, V.34 could support 14.4 kpbs on lines that V.32bis could not and
where V.32bis would have to drop down to lower speeds. In practice this is
a quality of implementation issue which may not be present in current products.
--------------------------------------------------------------------------------
Subject: I.8 How good is V.34?
--------------------------------------------------------------------------------
an171@FreeNet.Carleton.CA (Anthony Hill) writes"
Well first of all if you're getting a 14.4 connection between two
v.34 connections, the chances of you ever getting a 14.4 connection
between two v.32bis connections are next to nill since v.34 is so much
better at handling poor lines (I get 28.8/28.8 or 28.8/26.4 connects most
of teh time on what are fairly average lines for North America). Also
v.34 is asymetrical, meaning you can have the protocol talking faster in
one direction then in the other direction, so you might end up with a
14.4/16.8 connections where as with v.32bis you'd only have a 14.4
connection (well actualy you'd rpobably have a 7200 or 9600 connection, if
any at all). Basicaly v.34 is better then any other ITU-T protocol in
pretty much every way. Of course a v.34 modem connecting to a v.32bis
modem will provide no advantage over a v.32bis modem connecting to another
v.32bis modem as modems must can only use the highest common protocol.
--------------------------------------------------------------------------------
Subject: I.9 What is the difference between a good V.34 modem and one made
by Joe?
--------------------------------------------------------------------------------
V.34 has a collection of implementation options which will affect the
eventual performance of the modem. Some options to look for in a product
are asymmetrical transmission, auxiliary channel, lower speed baud rates,
nonlinear encoding, precoding, trellis states, etc. Good quality modems
will have implemented more of the V.34 options. [Hopefully they would have
also done a *GOOD* job in the implementation.]
Data Communicatons magazine, Nov 1994, pg 99-108 is a good reference to these
options and their impact on interoperativity and performance.
Two good V.34 modems are more likely outperform two Joe Average modems. The
enhanced performance will be noticeable on lousy lines, and may be noticeable
on good lines.
This also means that a good V.34 modem connecting with the "Joe" modem will
not notice any performance benefits.
--------------------------------------------------------------------------------
Subject: I.10 What will happen to the old models?
--------------------------------------------------------------------------------
They will still be sold.
Kolja Waschk (kawk@Yo.COM) writes:
ZyXEL said they'd implement whatever [subset of V.34] is possible on the

Subject: I.11 Will ZyXEL implement a subset of V.34 on the 1496 series?
--------------------------------------------------------------------------------
Kolja Waschk (kawk@Yo.COM) writes:
As far as I know, it is IMPOSSIBLE to handle any v.34 'subset' with the U1496
hardware. v.34 needs more processing power even for the lower speeds than
other 19k2 methods like ZyXEL's own 19k2 and v32.terbo; more than the U1496
series offer. Correct me if I'm wrong.
--------------------------------------------------------------------------------
Subject: I.12 What is ZyXEL's upgrade plans for the 1496RN+ modems?
--------------------------------------------------------------------------------
That will depend upon whether or not the new board can fit (physically)
into the existing chassis. Officially, there has not been a decision as
far as upgrade path for the rack mounts. The LED model will come out
first, then the LCD, and then rack.
--------------------------------------------------------------------------------
Subject: I.13 Why can not the new V.34 modems do faxing at 28.8 kpbs?
--------------------------------------------------------------------------------
Currently there is no ITU-T standard for faxing at 28.8 kbps. When this
standard exists, ZyXEL will implement faxing at 28.8 kbps.
--------------------------------------------------------------------------------
Subject: I.14 What are flash ROMs and how will they work?
--------------------------------------------------------------------------------
The current U-1496 generation of ZyXEL modems update ROM versions via a ROM
*replacement*. This involves opening the modem, removing the ROM chips, and
inserting the new chips.
The new ZyXEL modems will have flash ROMs to facilitate ROM updates. Users
will get a new copy of the ROM images, and run a program in DOS or in MacOS.
The new ROM images are sent to the modem, and the new images are "flashed"/
written to the flash ROM chips. This method of ROM updates should be much
easier to perform.
brentm@zyxel.com (Brent Mosbrook) writes:
The [flash] chips are rated at 100,000 flashes..
--------------------------------------------------------------------------------
Subject: I.15 How will the parallel port on the modems work?
--------------------------------------------------------------------------------
The new ZyXEL Elite modems have a parallel printer port on them. An Elite can
be hooked up directly to a HP Deskjet/LaserJet/PCL-based printer. The Elite
will then send all incoming faxes to the printer. In effect, the printer will
become an incoming-only plain paper fax machine. The computer is thus bypassed,
thereby removing the usual requirement for the computer to be turned on (to
receive faxes).
When the optional 2/4/8 Mb of RAM is installed, incoming faxes can be stored
in the modem itself. The stored faxes can then be sent to the PC for futher
processing.
The modem will work on HP LaserJets and other PCL-based printers. Postscript
printers are not *currently* supported (stay tuned!).
--------------------------------------------------------------------------------
Subject: I.16 What is the benefit of the using the parallel port?

Subject: I.17 Can the second port be used for other purposes?
--------------------------------------------------------------------------------
Only one port can be used on the new modems. Users *cannot* use the
other port for diagnostic, statistic, or call progress reporting purposes.
--------------------------------------------------------------------------------
Subject: I.18 Why is there not an ethernet interface on the modem?
--------------------------------------------------------------------------------
Brent Mosbrook (brentm@zyxel.com) [ZyXEL USA] writes:
We're looking into providing an ethernet interface. I don't have details
as to which product, nor when it will be available though. As soon as
concrete info is available, I'll post.
--------------------------------------------------------------------------------
Subject: I.19 What is ISDN?
--------------------------------------------------------------------------------
Modems (MOdulators and DEModulators) take data from the computer and
modulates the data into sounds for transmission over the phone line. The
modem on the receiving computer demodulates the sounds into data, which is
then send to the connected computer.
The modulation and demodulation process is inefficient. A better way to
transmit the data is to avoid the mod/demodulation process. Use digital
lines, and send the data digitally -- essentially, this is the purpose of
ISDN.
ISDN (Integrated Services Digital Network) is an additional *paid* service
from the telephone company. It is a high bandwidth technology that allows
users to send large amounts of information in short amounts of time. While
V.34 can send data at 28.8 kbps, ISDN can send data at 128 kpbs.
Basic Rate Service (BRS) ISDN, or 2B+D is composed of two 64 kbit/s digital
channels and one 16 kbit/s control channel.
--------------------------------------------------------------------------------
Subject: I.20 What is required for an ISDN hookup?
--------------------------------------------------------------------------------
Buy a ZyXEL modem that is ISDN equipped, or buy the ISDN upgrade module for
the new ZyXEL modem. Get an ISDN line wired to premises. Subscribe to BRI
ISDN. Buy a a NT1 adapter (U interface). Plug the modem into the NT1 adapter
and plug the NT1 into the ISDN connection. The ZyXEL modem (technically no
longer a MODulator/DEModulator) is now connected via ISDN.
--------------------------------------------------------------------------------
Subject: I.21 Why doesn't ZyXEL include the NT1?
--------------------------------------------------------------------------------
Not all countries implement ISDN the same way. Some are given the NT1 by
the telco.
--------------------------------------------------------------------------------
Subject: I.22 What are the benefits of ISDN?
--------------------------------------------------------------------------------
Speed and flexibility.

Nobody has yet talked about the speed of ISDN. It's ideal for remote

ISDN allows the following connection possibilities:
1. 1B - ISDN (64k)
2. 2B - ISDN (128k)
3. 1B - ISDN (64k)
1B - External Analog device (phone, fax, modem)

5. 1B - V.34 over ISDN (to a remote analog device) up to V.34 speeds

In scenario 5, users can use one B channel to maintain an ISDN connection.
SIMULTANEOUSLY, users can either talk/fax/modem/voicemail on the other B
channel. <Editor's note: "Awesome eh!">
--------------------------------------------------------------------------------
Subject: I.23 Can normal analog phone calls be made after the ISDN upgrade?
--------------------------------------------------------------------------------
Yes.
Brent Mosbrook (brentm@zyxel.com) [ZyXEL USA] writes:
"If you have the ISDN module, you can still do V.34 links. The ISDN
module allows you to simulate an analog line, so you can still connect to
any other V.34 modem that has a POTS line.
IF you want to plug the ISDN-interface equipped modem into a real POTS
line, then you would have to open the modem, remove the ISDN module, and
replace it with the analog module. This is probably only an issue for
folks who take their modems with them on trips and such.. The whole point
of the ISDN module is to give you the flexibility to connect to EITHER
type of remote device."
--------------------------------------------------------------------------------
Subject: I.24 What kind of call processing does ZyXEL support?
--------------------------------------------------------------------------------
Computer telephony can be defined as computers and telephones working together.
The computer will control perform the "call control/processing" tasks such as
dialling, answering, transferring, and conferencing of the phone line.
Currently, there are more than a few "standards" for call processing. These
standards include the AT&T/Novell Telephone Services Application Programming
Interface (TSAPI), the Microsoft/Intel Telephony Application Programming
Interface (TAPI), the Macintosh Telephony Architecture (MTA), etc. A
true "standard" will emerge in due time.
[Ed.: Hopefully this new FAQ entry is factually correct.]
Brent Mosbrook (brentm@zyxel.com) [ZyXEL USA] writes:
We haven't announced support for TSAPI (Novell) yet, but as the article
mentioned, we will be supporting TAPI (Microsoft).
--------------------------------------------------------------------------------
Subject: I.25 Is the Euro-ISDN the same as the American-ISDN "modem"?
--------------------------------------------------------------------------------
There are hardware differences between the two "modems". Thus an ISDN "modem"
purchased in the Americas will not be Euro-ISDN compatible.
