2Plan the gatewayrouting prefixes. At least one prefix is needed per
Branch Office, although any branch offices that havea prefix forESA
"911" calls does not necessarily require another. (These prefixes will
be SPN - Special Number - entries if you are using ESA 911. In the
example these are LOC codes because network 911 is not being
used.) In our example the Branch Office prefixes are 741 (Branch
Office B) and 742 (Branch Office A).
3Provision 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
which provides service for the Branch Office using the LOC.In our
example the NRS is provisioned with 841 (for main office B) and 842
(for main office A).
4Provision the NRS to send all calls to a LOC with a gateway routing
prefix to the Branch Office directly. Using the gatewayrouting prefix
and the Typeof Number as used (LOC or SPN), the entries can be
differentiated from the normal LOCs easily.
In our example the NRS is provisioned with 741-841 at Branch Office
B and 742-842 for Branch Office A.
5Provision the main office with the DGT table DMIs to insert the
prefixes and set the Typeof Number correctly. Create RLB RLI
entries to use these DMIs for the VTRK route(s). One RLI per Branch
Office will be the minimum requirement. Note that calls from remote
systems will typically have the HLOC prefix, so this is defined here
