73D2248A/2348A
MNP5, V.42bis Datacom
Modem Device Set
April 2000
DESCRIPTION
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.
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.
