Chapter 1 - Introduction and Description

1.3.31432 Series Features

Your MT1432BL modem is designed according to the international CCITT V.32bis specification for data signalling rates as high as 14.4K bps in full-duplex mode.

The major application for the MT1432BL is in 4-wire leased line networks (replacing traditional V.29/ 9600 bps & V.33/14,400 bps modems) with the addition of dialback-up capability. With this capability, the dial-up feature saves any down time if the leased line fails. Since the MT1432BL operates according to CCITT V.32bis modulation, it can operate full-duplex over two wires, so that the dial back-up mode performs the same throughput as the leased line.

The MT1432BL is AT command set compatible and incorporates a number of capabilities beyond the basics of V.32bis operation. Other capabilities include CCITT V.25bis synchronous dialing, compatibility with CCITT V.42 error correction and V.42bis data compression in which data communication speeds approach 57,600 bps (depending on the file content and the receiving modem’s capability) and the data sent will be 100% error free.

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.
