Emergency Services configuration
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
Configuring the Branch Office zone
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
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.
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.
Avaya 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.
