Procedure 39
Configuring the Branch Office zone
Step
Action
1
Configure the Branch Office zone on the Branch Office.
In the Branch Office, only the zone number and bandwidth/codec
selection is configured.
Use the same zone number between the Branch Office and main
office. The main office configuration (
,
) provides the Branch Office zone
characteristics (local time, local dialing, and ESA).
2
Configure the ESN SPN.
The Branch Office must recognize the incoming digits on the Virtual
Trunk and remove all but the ESDN. The call is routed to a local
termination. ESA recognizes the call as an emergency call and
selects the correct route. Refer to
"Dialing plan configuration" (page
—End—
Configuring the NRS
The NRS must be configured for the ESA Special Number (SPN). The
NRS uses the ESA SPN to route the emergency call from the main office
to the Branch Office.
Nortel recommends that a consistent pattern be followed for all ESA calls.
For example, use "0" + ESN Location code of the Branch Office node + the
ESDN. An example for location code 725 would be: 0725911. The zero is
recommended to prevent a collision in the ESN data with the HLOC entry.
For more information, refer to IP Peer Networking Installation and
Commissioning (NN43001-313) .
Testing the number
Use
Procedure 40 "Testing ESDN using an MG 1000B Telephone" (page
to test the ESDN number from any telephone in the Branch Office.
