Main Office Configuration for Survivable Remote Gateway 50
Configuration Guide
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 which
provides service for the branch office using the LOC. See step 3 on
.
4
Provision the NRS to send all calls to a LOC with a gateway routing
prefix to the branch office directly. Using the gateway routing prefix and
the Type of Number of SPN, the entries can be differentiated from the
normal LOCs easily. See step 4 on
.
5
Provision the main office with the DGT table DMIs to insert the prefixes
and set the Type of 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. See step 5 on
.
6
Provision the main office with CDP DSCs (mapped by the RLI into
Location Codes) sufficient to uniquely identify all of its branch offices
(using extended location codes, if required); use the RLI index defined
for each branch office as the RLI value of the LOC definition. This is the
route to the branch office. See step 6 on
7
Provision the main office and branch office with a home location code
(HLOC) or multiple codes to terminate all calls that should terminate on
this system. See step 7 on
8
Provision the main office to send all other LOCs to the IP network
without prefixes. These are going to a remote main office. See step 8 on
.
9
Provision the branch office with a terminating RLI with a DMI to delete
the LOC prefixes. See step 9 on
.
