ISDN Test Call Test (#258)
This non-destructive test performs a far- end looparound test over an ATM-BCH
trunk if
■the trunk is IN-SERVICE, MAINTENANCE/NEAR-E ND, or
OUT-OF- SERVICE/NEA R-END
■no calls are active on the trunk
■the system uses country protoc ol 1 (including US) or the far-end has
looparound cap ability
The test sets up a call to a far-end switc h over the ATM-BCH trunk. Then the
digital port on a TN711D Maintenanc e/Test circuit pack sends a bit p attern to the
far-end and bac k. If the received pattern ma tches that sent, the test passes. If
there are differences, it fails.
Synchronous Test Calls
You can initiate a synchronous outgoing test c all (including a test c all for
ISDN-PRI trunks) with these commands:
■test trunk
grp#/mbr#
long [repeat #]
■test board
UUCSS
long [repeat #]
■test port
UUCSSpp
long [repeat #]

1. See the ‘‘ATM-INTF (TN2305/6)’’ maintenance object.
1004 ABORT B-channel in use.
1. See if a call is active. Run status trunk
grp#/mbr#
command.
2. If the service state is In-Service/Idle, retry the test.
1005 ABORT Bad configuration (for example, no Maintenance/Test circuit p ack)
1. Make sure that the Maintenance/Test Circuit Pack is inserted.
