4.3.1 HTU-C
The Total Access 3000/3010 HDSL Transceiver Unit - Central Office (HTU-C) is a
central office transceiver unit that works with an HDSL Transceiver Unit-Remote
(HTU-R) and up to two HDSL Range Extenders (HREs) to establish T1 data rates over
the local loop. The unit is designed to operate in the shelf, which can accommodate up
to 28 HDSL circuits. See Figure 10.
The HTU-C functions as the host in a host/client arrangement, with the HTU-R and the
HRE as the clients. All of the HTU-C HDSL circuit parameters are configured in the
software. These parameters are then automatically communicated to the HTU-R upon
synchronization. The HTU-C can operate in MUX configuration (e.g. DS3-fed shelf)
or with direct DSX-1 input from the network.
