4.3.7 H4TU-C
The Total Access 3000/3010 H4TU-C is a high-density Central Office transceiver unit
that works with a remote unit (H4TU-R) and an optional H4R to establish T1 (1.544
Mbps) data rates over two copper loops. The unit is designed to operate in the Total
Access 3000/3010 chassis, which accommodates 28/22 HDSL4 circuits in a 6-inch tall
space. See Figure 16.
The H4TU-C functions as the master in a master/slave relationship with the H4TU-R
and H4R. The user configures the Total Access 3000/3010 H4TU-C HDSL4 circuit
parameters in software. These parameters are then automatically communicated to the
H4TU-R. The Total Access 3000/3010 H4TU-C provides comprehensive user-friendly
Operation, Administration, Maintenance and Provisioning (OAM&P) circuit
information for the entire HDSL4 circuit.
