Signaling Port LAN Loop-Back Test (#939)
This test is destructive.
This test verifies the connectivity of an ISDN-PRI signaling port (D channel)
across the packet bus, also known as the LAN bus. It will execute only if the port
is out of service. Failure of this test indicates a fault associated with the port
hardware on the circuit pack.
