The Application Enablement Services (AESVCS) Link Heartbeat Test sends a TCP tunnel connection heartbeat message to the far end AESVCS Server. If the AESVCS Server fails to return a response to the heartbeat message, the test fails. An AESVCS Link that fails a Heartbeat test is subsequently deleted from the AESVCS Session.

This test is run for AESV-LNK (AE Services Link) and AESV-SES (AE Services Session).
