4.3.5 H2TU-C
The Total Access 3000/3010 H2TU-C is a high-density Central Office transceiver unit
that works with a remote unit (H2TU-R) and an optional H2R to establish T1 (1.544
Mbps) data rates over a single pair copper loop. The unit is designed to operate in the
Total Access 3000/3010 chassis, which accommodates 28/22 HDSL2 circuits in a 6-
inch tall space. See Figure 14.
Figure 14. H2TU-C Faceplates
The H2TU-C functions as the master in a master/slave relationship with the H2TU-R
and H2R. The user configures the Total Access 3000/3010 H2TU-C HDSL2 circuit
parameters in software. These parameters are then automatically communicated to the
H2TU-R. The Total Access 3000/3010 H2TU-C provides comprehensive user-friendly
Operation, Administration, Maintenance and Provisioning (OAM&P) circuit
information for the entire HDSL2 circuit.
