This test checks the circuitry involved in the data path of a peer-to-peer IP layer connection. It is only run for those signaling groups that have an administered far-end IP address. If the H.323 or SIP signaling group does not have an administered far-end IP address, the test will abort.
The test determines the local PROCR through which the signaling originates, and the far-end terminating IP address. It then requests the local PROCR to execute a PING on the far-end address. If the PING is successful, the test passes. If the ping is not successful, the test fails.
Note:
Multiple failures of this test will cause this signaling group’s associated H.323 or SIP B-channels to be taken out of service (OOSFE). This will allow incoming calls to be made when the far-end comes up before the near end has detected it. The signaling group will be left in service, but in the far end bypass state.
If the PING is successful, the test looks at the PING round-trip delay. If a round-trip delay of greater than 4 seconds is reported, a separate error is logged. Excessive round-trip delays within the signaling group will not take the signaling group out of service.
The standard PING command can be executed using the PROCR board’s address and far-end IP address from the signaling group screen to see the actual round-trip delay.
This test runs on H323-SGR (H.323 Signaling Group) and SIP-SGRP (SIP Signaling Group).
