1. GENERAL
The ADTRAN 3192 HDSL4 Transceiver Unit for the
Central Office (3192 H4TU-C) is used to deploy an
HDSL4 T1 circuit using 4-wire metallic facilities. The
unit occupies one slot in a 3192 chassis.
trates the 3192 H4TU-C (P/N 1223404L2).
Revision History
This is the first release of this document. Future
revisions will be explained in this paragraph.
Description
The DS1 or DSX-1 input signal is supplied from the
network. The HDSL4 signals are provided to the local
loop. The 3192 H4TU-C works in conjunction with the
H4TU-R and up to two H4Rs to provide a DS1 service
on the local loop.
