Figure 36
Call flow for Scenario 1 - call to remote Branch Office (destination side)

1. Main office B determines that LOC 444 is to a local Branch Office with

prefix 225. The system transmits 225-444-3456 to the NRS. The NRS
checks its provisioning, and determines that this call goes to Branch
Office B1.

2. The main office sends the call to 225-444-3456 to the Branch Office.

The Branch Office deletes the prefix, discovers the call is to its HLOC,
deletes the HLOC, and rings set 3456.

Summary of provisioning procedures for Tandem Bandwidth
Management

Use

Procedure 3 "Provisioning Tandem Bandwidth Management" (page

106)

to provision the network.

Step

Action

1

Enter the main office Gateway endpoint identifier in the Tandem
Endpoint field for each Branch Office gateway configured on the
NRS. This provides tandeming for outbound calls from a Branch
Office through its main office. See

step 1

.

2

Plan the gateway routing prefixes, if not already done. At least one
prefix is needed per Branch Office, although any branch offices
that have a prefix for ESA "911" calls does not necessarily require
another. (These prefixes will be SPN - Special Number - entries.)
See

step 2

.

3

Provision the NRS to send all calls to a LOC without a gateway
routing prefix to the main office of that LOC, or to the main office
