Introduction
The PT7A6632 HDLC controller operates at layer 2
(data link protocol level) of the Open Systems Inter-
connection (OSI) reference model. It supports HDLC
and ISDN implementations.
The PT7A6632 processes data transmitting and re-
ceiving on a T1 or E1 communication link. It con-
nects between the T1/E1 serial bus and an external
memory shared with CPU(s), multiplexing /
demultiplexing up to 32 fully-duplex high-speed data
channels.
It provides additional functions that support X.30 and
X.31 rate adaptation and fully flexible hyperchannels.
