Survivability Test - Avaya 1000 Installation And Commissioning Manual

MG 1000B telephones
register at the main office, it returns to the Branch Office (displaying "Server
Unreachable"). The terminal keeps repeating the pattern.
Consequence: The IP Phone does not successfully provide call service.
Diagnosis: When this behavior is observed, check whether a ping succeeds from the IP
Phone's subnet to the main office TPS subnet.
Caution:
After all IP Phones are installed, perform a datadump (using LD 43 EDD or through NRS
Manager) on the MG 1000B CP PM. Refer to Avaya Communication Server 1000E:
Installation and Configuration (NN43041-310) for more information.
7. Execute the EDD command in LD 43.

Survivability test

This section pertains to IP Phones installed at a Branch Office.
When LAN/WAN connectivity is lost, the IP Phones reboot and are registered at the MG 1000B Call
Server. When LAN/WAN connectivity is reestablished, each telephone re-registers at the main
office.
After the MG 1000B IP Phones are installed and configured, test the IP Phones for survivability. This
is highly recommended when installing the BUID and MOTN through overlays. In these cases, the
IP Phones are automatically redirected to the main office without the opportunity to test for Local
Mode functionality.
When the Main Office TN is prompted during Branch User Config, and the MOTN is not configured
through the LD configuration, then the default value is displayed as shown in the following figure.
The default is the Branch Office TN in Large System format. The user may press the Select softkey
to accept the default or enter a new Main Office TN (in 4-fields TN format) and then press the Select
softkey.
