PSTN fallback feature
The Public Switched Telephone Network (PSTN) fallback feature 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, DEFINITY’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, the TN802 circuit pack should not be placed 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.
