| Circuit maps within H.323 systems |
 |
This Recommendation specifies a mechanism that allows a PSTN - H.323 Gateway to report circuit service and usage status to a Gatekeeper using the circuit status map parameter. Individual PSTN circuits on the Gateway may be taken out-of-service by a provisioning command from service personnel or when an ISUP out-of-service or blocking message is received from the adjacent PSTN switch. In this case, the Gateway will be able to report the current circuit status to the Gatekeeper so that it may select only from available circuits for outgoing calls through that Gateway. |
