ISDN Test Call Test (#258)
This nondestructive test performs a far-end loop-around test over an ATM-BCH
trunk if:
■
The trunk is IN-SERVICE, MAINTENANCE/NEAR-END, or
OUT-OF-SERVICE/NEAR-END.
■
No calls are active on the trunk.
■
The system uses country protocol 1 (including US), or the far end has
loop-around capability.
The test sets up a call to a far-end switch over the ATM-BCH trunk. Then the
digital port on a TN711D Maintenance/Test circuit pack sends a bit pattern to the
far end and back. If the received pattern matches that sent, the test passes. If
there are differences, it fails.
Synchronous Test Calls
You can initiate a synchronous outgoing test call (including a test call for
ISDN-PRI trunks) with these commands:
■
test trunk grp#/mbr# long [repeat#]
■
test board UUCSS long [repeat#]
■
test port UUCSSpp long [repeat#]
Table 8-74.
