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
‘‘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.
5. Enter
display trunk xx p
command for each trunk group identified in Step
3. This command displays the specified trunk group on the administration
terminal screen and prints a hard copy on the printer. Save this data for
later use.
6. Remove all members defined by these ports from the trunk group(s) using
the
ch trunk xx
command.
7. Remove the Tie Trunk circuit pack from the carrier slot.
