Zoom Telephonics: Zoom V.34I Plus and V.34X Plus FaxModems
The Zoom V.34IPlus and
V.34XPlus FaxModems
The Zoom/FaxModems Model 2805 V.34I Plus
(internal) for PC, Model 2836 V.34X Plus (external)
for PC, and Model 2837 V.34X Plus (external) for
Macintosh provide 28,800 bps uncompressed data
transmission over conventional telephone lines, using
the V.34 protocol and up to 33,600 bps with
enhanced data throughput. The V.34 standard is the
fastest data communications protocol approved by the
ITU, the international standards body for
telecommunications.
The V.34I Plus and V.34X Plus also provide 14,400
bps send/receive fax, and full V.32bis compatibility
for connection to slower modems. They include a
synchronous interface that supports the ITU H.324
videophone technology standard.
Bundled software with PC models includes: DOSfax
and 01 Communicate! data communications for DOS
and Windows® with Macintosh model: STF
STartFaxing and MicroPhone LT.
About the Zoom/FaxModems V.34I Plus and V.34X Plus
The Zoom/FaxModem V.34I Plus internal and V.34X Plus external are full-featured modems that
support both the international V.34 standard for 28,800 bps data transmission and 33,600 bps for
enhanced throughput. They both support Class 1 at speeds up to 14,400 bps. Since these
faxmodems also support the international standards at slower speeds and can automatically adjust
to slower speed modems and faxmodems, they will communicate with virtually any modem or fax
machine in the world. They are ideal for accessing on-line services and the Internet.
The Zoom/FaxModem V.34I Plus and V.34X Plus are designed for high-speed, error-free
communications. The V.34I Plus and V.34X Plus use adaptive line probing and multi-dimensional
trellis coding techniques to achieve very high data throughput and reliable connections. They can
communicate at up to 33,600 bps with uncompressible data. When the data can be compressed

using the built-in V.42bis and MNP compression, even higher speeds can be achieved. They also
support V.42 and MNP automatic error correction, and MNP 10EC for more reliable cellular,
transcontinental, and international communications. Since all these standards are hardware-based,
all connections are automatically negotiated for the fastest speed and the highest possible level of
compression and error correction supported by both modems.
The Zoom/FaxModem V.34I Plus and V.34X Plus also support the V.17 fax standard for fax
speeds up to 14,400 bps when communicating with other V.17 compatible modems and fax
machines, and at 9600 bps for most other fax machines. For many applications you'll find these
products are faster, easier and produce results that are superior in quality to a conventional fax
machine. They make it easy to "broadcast" personalized faxes to groups of people, to schedule fax
deliveries when connection rates are low and to forward a fax with no loss of clarity. The quality of
faxes sent with a Zoom/FaxModem is far better than the quality of those sent using a fax machine.
The Zoom/FaxModems V.34I Plus and V.34X Plus include a synchronous interface that supports
the ITU H.324 videophone technology standard.* They support the complete Hayes command set,
plus all the Microcom commands required for MNP operation. They are protected by ZoomGuard
lightning and surge protection, which includes a SIDACtor® and other advanced components for
much better protection than provided by metal oxide varistors (MOVs).
They are built in the USA by Zoom Telephonics, Inc., a leading supplier of telecommunications
equipment since 1977, and backed by Zoom's outstanding seven-year warranty.
