Chapter 6 H.248 Packages—Signaling and Control

H.248 Termination State Control Package

•The tsc/gtd and tsc/ata properties and the tsc/dc event (if subscribed for) are reported to the MGC in Audit responses.

The tsc-suspend Feature

The tsc-suspend feature includes the following functionality:

•Termination association (by context or VLAN) is not relevant to tsc-suspend.

•The trt property may be set to ON only when changing a termination to OutOfService. Modification of trt can cause the following error cases:

–trt set to ON and ServiceState set to InService.

–trt set to ON and ServiceState is not supplied (in which case it defaults to InService).

In each case, the transaction is failed with error 421, “Unknown action or illegal combination of actions.” This policing occurs before any other processing or checking.

•The MG ignores cases where the termination is already OutOfService when trt is set to ON.

•If the recovery timer is running and LocalControl is modified:

–If trt is ON and the recovery timer (rt) is non-zero, the recovery timer will be cancelled and restarted with the new rt value.

–If trt is OFF or rt is zero, the timer is stopped.

•If the MGC manually changes a suspended termination from OutOfService to InService, the recovery timer is stopped. However, if the MGC re-applies OutOfService state to an already suspended termination, this has no effect on the recovery timer and does not cancel recovery.

•The tsc/trt and tsc/rt properties and the tsc/rc event (if subscribed for) are reported to the MGC in Audit responses.

DBE Restrictions

The following is a restriction of DBE support for the tsc package:

•Terminations can be associated by context, but not by VLAN. This means that the VLAN value of the tsc/ata property is not supported. If a request includes the VLAN value, the request is rejected with error 501, “Not Implemented.”

Note See the MultiService Forum Contribution document, Contribution Number: msf2006.117.03 for more information about the tsc package.

Related Commands

The tsc/ttr statistic is reported in the show sbc dbe media-flow-statsand show sbc dbe signaling-flow-statscommand outputs. The tsc/trt property is reported as ON if the termination is OutOfService with the recovery timer running, and OFF otherwise.
