Main Office Configuration for Survivable Remote Gateway 50

Configuration Guide

After configuring the specialized route for calls that have been routed
to the branch office by the NRS, the route must be associated with
the ESN Special Number.

The branch office receives the manipulated number as an incoming
call, indicating that the ZDP value added at the main office is at the
beginning of the number. The branch office ESN configuration must
ensure that the extra digits (the ZDP value) are deleted by using a
proper DMI. The call then terminates at the PSTN connection.

Note: The DMI configured in LD 86 in step 1 on

page 187

is used to

remove the digits that were inserted in the dialed number at the main
office.

For example, assume ZDP at the main office = 101, Customer
number = 0, and the RLI for the PSTN trunk = 18.
