Communications Software

You will need data communications (datacomm), fax communications
software and, for the MultiModemZDX, an appropriate application software
package to access the Personal Voice-Mail features of the
MultiModemZDXV. The MultiModemZDX is also compatible with
datacomm and fax programs you may already own.
Product Features
General features include:
• Compliance with major ITU-T, TIA, and EIA international standards
to ensure compatibility with other modems.
• Distinguishes data, fax, or voice calls using DTMF and tone detection
with software packages supporting these features.
• Caller ID to identify your caller’s phone number (available on U.S.
products).

Data

• Supports the enhanced ITU-T V.34 standard, with data transmission
speeds to 33.6K bps, while also maintaining compatibility with lower-
speed modems.
• Supports asynchronous data rates at 33.6K, 31.2K, 28.8K, 26.4K,
24K, 21.6K, 19.2K, 16.8K, 14.4K, 12K, 9600, 4800, 2400, 1200, and
300 bps.
• Automatic fallback to slower speeds in noisy line conditions, and fall-
forward to faster speeds as conditions improve.
• ITU V.42 LAP-M and MNP Class 3 and 4 error correction.
• ITU V.42bis (4-to-1) and MNP 5 (2-to-1) data compression.
• Automatic disabling of compression when transferring already-
compressed files.
• Autodial, redial, pulse (rotary) and touch-tone dial.
• Dial tone and busy signal detection for reliable call-progress detection.
• Compatibility with the standard AT command set used by most
communication programs.
