Lamp audit and keep-alive function

553-3001-368 Standard 1.00
Internet Telephone maintenance and diagnostics
The Lamp Audit function provides a continuous source of heartbeat messages
to ensure the Internet Telephone is powered and the IP connection is working.
Since there is a reliable UDP connection from the system core through to the
Internet Telephone, any failure of the Internet Telephone, the Voice Gateway
Media Card or the IP connection is detected.
You can run Network Signaling diagnostics as part of the midnight routines
with LD 30.
When the TPS detects the Internet Telephone has been disconnected, the IT
Line card logs the event and sends an UNREGISTER message to the Call
Server for that Internet Telephone.
When the Call Server detects a loss of connection with the Voice Gateway
Media Card, the system logs a message and UNREGISTERS all of the
Internet Telephones and gateway channels associated with that card.
