Description: The TTC Centest 650-S is a centralized test system that remotely tests DS3, DS1, DS0, and DDS circuits accessed from a digital cross connect system (DCS) or other network element. With the ability to test services and facilities throughout the entire network from the network control center, the Centest 650-S offers the ability to lower maintenance costs, improve responsiveness to customers, and enable more efficient network troubleshooting.
The DTU module provides maximum testing flexibility by using a programmable DSP-based design. Configurable for DS1 facility access digroup (FAD) and fractional T1 (FT1) testing from a 3/1 or 1/0 DCS, the DTU module also provides DS0 test access digroup (TAD) testing from a 1/0 DCS, including voice frequency (VF) and DDS. Using a test port on an Alcatel 1630 or DSC DEX CS 1/0 DCS, the DTU module nonconcurrently performs single, dual, or universal FAD testing on a DCS with a test port, reducing the need for two DTU modules. And with optional DS0 drop and insert software, the DTU module will perform all DS0 testing from a 3/1 DCS. As your mix of services changes over time, the DTU module adapts to meet your specific needs, maximizing your investment in Centest equipment.
The DTU module and the Centest 650-S platform enables you to monitor and maintain existing services and facilities as well as verify the quality of new VF, DDS, FT1, and DS1 circuit installations. When the DTU module is coupled with the DS3 capabilities of the Centest 650-S, the combination is your complete central office test solution.
