Survivability Test - Nortel 1000 Branch of?ce Installation And Commissioning Manual

276 MG 1000B telephones

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 reregisters 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 or TM 3.01. 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, if the
MOTN is not configured through the LD configuration, the default value is
displayed as shown in Figure 14. The default with CS 1000 Release 5.0 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 either 2 or
4-fields TN format) and then press the Select softkey.

Entry of Main Office TN
Validation of MOTN input from Branch User Config is limited to preliminary
range checks. The input string is converted to a packed TN and the MOTN
and MOTN type are set as either small or large system.
