Analog Tie Trunk Back-to-Back Testing
The TN760B circuit pack can be configured for back-to-back testing (also known
as connectivity testing) by making translation and cross-connect changes. This
testing configuration allows for the connection of Tie Trunks back-to-back in the
same switch to verify the operation of Tie Trunk ports. The tests can be
performed in either the E & M or simplex modes.
E & M Mode Test Procedure
The procedures to perform the Analog Tie Trunk port test in the E & M mode are
as follows:
1. At the administration terminal, enter list configuration trunks command
to determine which ports are assigned on the Tie Trunk circuit pack.
2. Enter display dialplan command to determine the Trunk Access Code
(TAC) format.
3. Enter display port xx command for all ports defined in Step 1. This action
displays the trunk groups to which the ports belong (that is, of which the
ports are members).
NOTE:
See the ‘‘Handling Control Circuit Packs’’ section in this chapter for
details on how to remove and replace port circuit packs.
4. Insert the circuit pack back into the slot.
