Test the System

This section provides tests to:

These tests verify the Time Division Multiplexing (TDM) cables, terminators, and the Inter-Cabinet Cables (ICC). If a FAIL Result code is seen or other problems are indicated, check these cables. If problems persist, refer to the relevant DEFINITY Maintenance documentation.

See LED Indicators for information regarding the LED status indicators for the different circuit packs.


Note: Circuit pack positions are usually given by cabinet, carrier, and slot. They may also be given by port. The term "cabinet" refers either to a stack of Single-Carrier Cabinets or to a Multi-Carrier Cabinet making up one port network. A port network is defined as a group of cabinets connected together with one TDM bus.
