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.
