Main Office Configuration for Survivable Remote Gateway 50 Configuration Guide
Call between two local branch offices
Figure 38 on page 124 shows the call flow of a call between two local branch
offices.
1, 2, 3 All CDP numbers must be sufficiently long to allow unique
termination of the calls. That is, every main office/branch
office region requires its own LSC to ensure that all numbers
are unique.
1, 2, 3 Prefixes for branch offices for regular calls are required. May
have additional prefixes for E-911 calls, if required, or may
share prefixes.
1 All branch offices are provisioned at the NRS to route all calls
through the main office.
1 Main office sends all CDP calls to destinations that are not its
own branch office to the NRS with unchanged dialled digits.
1 Main office sends all CDP calls to destinations that are its own
branch office to the NRS with a specific gateway prefix in front
of the dialled digits.
1 All branch offices delete the prefix and terminate the calls.
May be to a local set or to a trunk.
2,3 Similar configuration, as above, applies to regions 2 and 3.
