1. GENERAL
The ADTRAN 3192 HDSL4 Transceiver Unit for the
Central Office (H4TU-C) (ADTRAN P/N
1222404L1) is used to deploy an HDSL4 T1 circuit
using 4-wire metallic facilities. See Figure 1. The
unit occupies one slot in a 3192 shelf.
The DS1 or DSX-1 input signal is supplied from the
network. The HDSL4 signals are provided to the
local loop. The ADTRAN 3192 H4TU-C works in
conjunction with the ADTRAN H4TU-R and up to
two H4Rs to provide a DS1 service on the local loop.
