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
to provision the network.
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 on
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 on
