Configure the branch office zone on the main office.
a. Configure the branch office zone ESA dialing information in LD
117.
Description
Defines the ESA parameters for the branch office zone, where:
• Zone = Zone number for the branch office.
• ESA Route # = Virtual Trunk route to SRG.
• AC = Access Code to add to dialed digits. If no AC is required, enter
AC0 in place of AC1 or AC2.
• ESA Prefix = Digit string added to start of ESDN. This is a unique
prefix in the NRS. Nortel recommends that users use 0 + ESN location
code of the branch office node. An example for location code 725
would be: 0725.
• ESA Locator = Direct Inward Dial telephone number sent as part of
ANI for use by the PSAP to locate the source of the call.
b. Enable the branch office zone ESA in LD 117.
ENL ZBR <Zone> ESA
Configure the ESA Special Number at the main office.
Configure the ESA Special Number in the NRS. Using NRS,
configure the ESA Special Number defined for the branch office
zone. See IP Peer Networking Installation and Commissioning
(NN43001-313).
Nortel recommends that customers use "0" + the ESN Location code
+ 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.
Do the following:
a. In LD 86, configure Emergency Service Access Digit
Manipulation for AC + ESDN dialing to allow recognition of the
ESDN even if AC1 or AC2 is used.
