MNP5, V.42bis Datacom

Modem Device Set

April 2000

DESCRIPTION

FEATURES

The 73D2248A/2348A Device Sets consists of two

CMOS integrated circuits which provide the data

pump and protocol functions required to implement a

high performance 2400 bit/s modem with error

control and data compression. The 73D2248A basic

modem function is provided by the 73K224L modem

chip and is compatible with CCITT V.21, V.22,

V.22bis and Bell 103 and 212A protocols. The error

control functions are provided by modular software

running in the 73M2910 controller. Modules are

available for MNP4, and V.42. Compression

software modules can be added to the controller;

MNP5 and V.42bis are available. Provisions for

customization of the command set are provided,

forming the basis for an international modem.

Combines modem and protocol controller

Supports 0 - 300, 1200 and 2400 bit/s with both

sync and async modes

Modular software design allows customization

Modem protocols:

Bell 103 (73K224L), 212A

CCITT V.21, V.22, V.22bis, V.23 (73K324L)

Error control/compression protocols Available:

MNP4, MNP5, CCITT V.42, V.42bis

Supports non-volatile memory to store user

configurations and phone numbers

The 73D2348 differs from the 73D2248A in that it

uses the 73K324L instead of the 73K224L for the

data pump. The 73K324L replaces the Bell 103, 300

bps (bit/s) FSK mode of operation, with the CCITT

V.23, 1200 bps (bit/s) FSK mode. The software is

also modified to support V.23. The two products are

otherwise identical.
