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:

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

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
================
Main Features:
* ITU-T V.34 28,800bps to 2,400bps
* ZyXEL 19,200bps mode

* Microphone/Speaker voice interface
* Versatile telephony functions
* Universal data dump
* 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>

no need for U interface (NT1) *and* more that I can't quote off my head.
<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).

Subject: Q.14 What are additional methods to contact ZyXEL USA technical
support?
--------------------------------------------------------------------------------
[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.

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.
