PSTN fallback

Public Switched Telephone Network (PSTN) fallback is available on the Internet
trunk application software, which periodically pings the remote destinations that
the software calls. When the far end returns a poor response time to the ping,
Avaya MultiVantage Software's ARS or AAR network routing patterns bypass
those ports and direct the call to another port, typically on a PSTN trunk.
When the remote destinations show acceptable response times to subsequent
pings, the corresponding ports are returned to "idle," where they are available for
service.
Cabinet configuration
Because of overheating, do not place the TN802 circuit pack directly above or
below another MAPD circuit pack.
UPS protection
Because Windows NT is more vulnerable to damage from a power interruption
than the Avaya Definity Server, uninterrupted power supply (UPS) protection is
strongly recommended for systems using the TN802 circuit pack.
