7 Test ESDN using a main office telephone to confirm that main office
calls go out the main office trunks.
If OSDN is used, the ESA route number must be blank to make test
calls without using any trunk resources. It the route number has
been configured, remove it by entering "x" at the prompt.

Procedure 38
Configuring the Branch Office
Step Action
You can use Element Manager or the Command Line Interface for this
procedure. Refer to IP Peer Networking Installation and Commissioning
(NN43001-313) .
1 Configure an emergency trunk (CAMA or PRI).
2 Configure the Virtual Trunk.
Before a call can come in on the Virtual Trunk, the Virtual Trunk
must be configured.
3 Configure ESN.
A Special Number (SPN) is configured at the Branch Office. The
SPN contains the digits sent to the NRS to route the emergency call
from the main office to the Branch Office.
The SPN must use:
• A Route List Index (RLI) with local termination
• A Digit Manipulation Index (DMI)
The system deletes the routing digits, leaving only the
Emergency Services DN (ESDN).
When an SPN is configured, ESA determines that the call is from a
trunk and forwards the correct ANI data as it tandems the call.
4 Configure ESA.
ESA configuration enables:
• telephones to connect to the MG 1000B Call Server (digital
devices, analog devices, attendant consoles) and to dial the
ESDN
• the Virtual Trunk (and any other trunks) to tandem a call to ESA
