Chapter 1 - Introduction and Description

1.3.1MT2834BA/BL Series Features

Your MT2834BA/BL modem meets the proposed Enhanced V.34 ITU standard for data signalling rates as high as 33.6/31.2K bps in full duplex mode. Enhanced V.34 is an extension of V.32/V.32bis/ V34 standards, and supports and is compatible with those features, including EIA extended Automode; adaptive line probing; automatic symbol rate and carrier frequency during start-up; and retrain and rate renegotiation (in 2400 bps increments).

The major application for the MT2834BL is in 4-wire leased line networks with the addition of dial backup capability. With this capability, the dial-up feature saves any down time if the leased line fails. Since the MT2834BL operates according to ITU V.34 modulation, it can operate full-duplex over two wires, so that the dial backup mode performs the same throughput as the leased line.

The MT2834BA/BL features ITU V.25bis standard for synchronous dialing, ITU V.42 error correction and V.42bis data compression, providing 100% error-free data transmission. V.42 error correction incorporates MNP( Classes 3 and 4, and LAP-M. You may select V.42bis data compression for 4-1 throughput, or MNP Class 5 for 2-1 throughput.)

1.4Fax Features

Your modem meets the ITU V.17 standard for sending and receiving faxes. When linked to a compatible fax machine or modem, it can transmit faxes at 14,4 K bps. It also meets the ITU’s Group 3 Designation for sending and receiving faxes at 9600 bps; and Group 2 Designation for sending and receiving faxes at 4800 bps. The modem is also downward-compatible with modems to speeds as low as 300 bps, so it can send and receive faxes with any fax machine in the world.
