2. Overview
The V.92 Dialup 2-Wire or 4-Wire Leased-Line Data/Fax Modem supports two- or four-wire leased lines. Since
leased-line operation uses two client modems connected to each other, the maximum leased-line data rate is
33.6 kbps.
The modem offers interactive automatic dialing. You can store four command lines or telephone numbers of
up to 30 characters each in the modem’s nonvolatile memory. The modem pulse- or tone-dials, and recognizes
dial tones and busy signals for reliable call-progress detection. It can also detect AT&T®calling-card tones. It is
FCC-registered for connection to telephone networks without notification to the telephone company.
The modem’s front panel includes a liquid crystal display (LCD) and four buttons, which together can be used
to either display the current connection status of the modem or to configure the modem. The modem also can
be configured through standard AT commands; these appear in the AT Commands Reference Guide that’s
included on the system CD that accompanies your system.
Additional features include:
• Complies with major international standards to ensure compatibility with other modems.
• Uses DTMF and tone detection to distinguish data and fax calls when used with software that supports these
features.
• Supports serial port speeds to 230.4 kbps with compatible serial ports.
• Supports automatic fallback to slower speeds in noisy line conditions, and fall-forward to faster speeds as
conditions improve.
• Supports both synchronous and asynchronous data transfer.
• Supports callback security and remote configuration.
• Supports AS/400®applications.
• Automatically disables compression when transferring already-compressed files.
• Can autodial, redial, pulse (rotary), and touchtone dial.
• Detects dial tones and busy signals for reliable call-progress detection.
• Supports plug-and-play (PnP) operation.
• Can be flash upgraded.
• Supports V.17, Class 1, Class 2 (V.92), and Group 3 fax standards, allowing it to communicate with other fax
modems as well as fax machines.
