Data
• Supports the K56flex
to 56K bps while maintaining compatibility with lower-speed modems.
Note: Under the 56K bps standards, you can asymmetrically download data from
an ISP at speeds up to 56K bps, but upload at speeds only up to 33.6K bps.
• Supports the enhanced ITU-T V.34 standard, with data transmission speeds to
33.6K bps, while maintaining compatibility with lower-speed modems.
• Supports V.90 and K56flex speeds plus 33.6K, 31.2K, 28.8K, 26.4K, 24K, 21.6K,
19.2K, 16.8K, 14.4K, 12K, 9.6K, 7.2K, 4.8K, 2.4K, 1.2K, and 0–300 bps.
• Supports automatic fallback to slower speeds in noisy line conditions, and fall-
forward to faster speeds as conditions improve.
• Supports ITU-T V.42 LAP-M and MNP Class 3 and 4 error correction.
• Supports ITU-T V.42bis (4-to-1) and MNP 5 (2-to-1) data compression.
• Automatically disables compression when transferring already-compressed files.
• Can autodial, redial, pulse (rotary) and touch-tone dial.
• Detects dial tones and busy signals for reliable call-progress detection.
• Compatible with the standard AT command set used by most communication
programs.
• Has MNP10 data throughput enhancement.
• Supports the H.324 protocol (videophone-ready).
• Supports distinctive rings to route voice, data, or fax calls on a single phone line.
• Supports Plug and Play (PnP).
• Can be upgraded by flash programming.
Fax
• Supports V.17, Class 1, Class 2, and Group 3 fax communication standards, allow-
ing it to communicate with other fax modems as well as with fax machines.
• Sends and receives faxes from your computer at 14,400 bps, 9600 bps, 7200 bps,
4800 bps, 2400 bps, or 300 bps.
Voice
• Can record and play back answering machine messages using connected tele-
phone handset.
• Remote/local telephone answering machine (TAM) capabilities include voice
mail control, record and playback, and call screening.
• Supports AT#V voice commands.
• Supports DSVD digital simultaneous voice and data.
