Zoom®/PC Card™ 56K FaxModem
About the Dualmode Zoom/PC Card 56K

The Dualmode Zoom/PC Card 56K Model 2975 for PC and 56K Model 2876 for Macintosh® can download data from compatible sites at up to 56,000 bps for fast internet and LAN access and provides up to 33,600 bps uncompressed data transmission over conventional phone lines, using the V.34 protocol.

The Zoom/PC Card 56K FaxModem also provides 14,000 bps send/receive fax.

Both models of the Zoom/PC Card 56K FaxModem come bundled with fax and data software and the PC version is also bundled with a memory saving enabler.

The Dualmode Zoom/PC Card 56K FaxModem is a state-of-the-art high-speed V.90 data/fax modem that can be used with a notebook, palmtop, PDA, or any computer with a compatible PCMCIA slot. It's at home in the office and on the road. Its small size, slim cord, rugged connector design, built-in DAA, and battery-conserving circuitry make the PC Card 56K the perfect traveling companion.

The Dualmode PC Card 56K can receive data from compatible sites at speeds up to 56,000 bps, and at higher speeds with compression.1 It incorporates both the V.90 ITU 56K Standard and K56flex™, the most widely supported non-ITU 56K technology, to achieve download speeds nearly twice as fast as any conventional analog modem. That means fast access to the Internet, World Wide Web, and local area networks (LANs) over standard phone lines. The Dualmode PC Card 56K automatically connects in ITU V.90 mode, K56flex mode, 33.6 Kbps, or any other ITU International or Bell standard speed to achieve the fastest, most reliable connection possible.

The Dualmode PC Card 56K has Class 1 14.4 Kbps send/receive fax capabilities for convenient printer-quality faxing to any faxmodem or fax machine. You can even "broadcast" your faxes to multiple recipients, schedule fax transmission, or forward them to another number.

It also includes V.80 capability for compatibility with H.324 Standard point-to-point videotelephony over regular phone lines and also supports H.323 Internet applications including video conferencing.

The Dualmode Zoom/PC Card 56K FaxModem permits software downloads to flash memory for all modem code, even DSP code. This protects your investment and permits fast, easy upgrades.

Bundled software for DOS, and Windows® includes fax and data software plus a memory-saving enabler.

Installing the Dualmode Zoom/PC Card 56K is fast and easy.2 Just plug it into a standard PCMCIA Type II, III, or Toshiba 16mm slot, and then attach to a telephone jack by means of the slim cord. A reprogrammable Digital Signal Processor (DSP) and flash memory make downloading updates for all modem code, including DSP and Controller code fast and easy.

The Dualmode Zoom/PC Card 56K features ZoomGuard™ lightning and surge protection, which provides much better protection than provided by ordinary metal oxide varistors (MOVs).

Sleep mode capability conserves power when the Dualmode Zoom/PC Card 56K is running on a computer's battery. When the faxmodem is in sleep mode, it "wakes up" when it senses activity, such as a modem command or an incoming call.

The Dualmode Zoom/PC Card 56K FaxModem is made in the USA by Zoom Telephonics, Inc., an industry leader in telecommunications since 1977.
