NOTE:
Avaya Communication Manager does not raise an alarm until the Link Loss Delay timer
expires. If the link to the original gateway is restored before this timer expires, then no
alarm is raised.
If the Link Loss Delay Timer expires but the gateway successfully connects with an LSP,
Avaya Communication Manager generates a warning alarm anyway, even though the
H.248 link is up.

• Administering the server timer
• Administering the Media Gateway
• Administering the gateway timers and Transition Point
