April 2000
Maintenance Objects
3-1154TSC-ADM (Administered Temporary Signaling Connections)
3
ADMTSC maintenance provides a strategy to verify that a far-end can respond to
an ISDN-PRI USER INFORMATION TSC heartbeat message, thereby indicating
that user to user signaling is functioning. In addition, maintenance can retrieve
the status of the ADMTSC’s connection state.
Since ADMTSCs are administered on a per signaling group basis, the health of
an ADMTSC also depends on the state of the D-channel or D-channel pair
administered per signaling group. Refer to ISDN-SGR (ISDN-PRI Signaling
Group) Maintenance documentation for details on ISDN-PRI NFAS and
D-channel Backup maintenance. The two administration commands for
ADMTSCs are as follows:
■ add signaling group #
■ change signaling group #
The two maintenance commands for ADMTSCs are as follows:
■ test tsc-administered signaling group #[/tsc index]
■ status tsc-administered signaling group #/tsc index

Notes:
a. There is no Test to Clear Value for error types 3840-3967. The error types
provide the following additional data that may prove useful when tracking
down problems.
This error indicates that a TSC Heartbeat Inquiry Test was run on an Active
far-end Administered TSC from the switch. Upon receiving the heartbeat
message, the network communicated to the switch that the call reference
value is not currently in use on the ISDN interface. As a result, the error
was logged. Check the signaling group status of the D-channel or
D-channel pair via the
status signaling-group <group>
command for the
Administered TSC. Check the status of the Administered TSC via the
status tsc-administered
command. Also check the administration of the
Administered TSC on the switch.
This error may only be affecting service for some DCS customers. Upon
receipt of this error condition, the switch tears down and re-establishes the
ADMTSC within 20 minutes.
b. The port field in the error log contains the signaling group number for
TSC-ADM errors.
