60 Dialing Plan configuration
For example, if ZDP = 101, it is possible to provision multiple
Numbering Plan Entries (101, 1011, and so on) to route calls based
on the ZDP value or the ZDP value plus some of the dialed digits.
Unlike on the Call Server, if the ZDP plus additional digits are
used to identify routing it is not necessary to provision all of the
combinations. For example, if calls with digit strings starting with
1011 are to be routed differently from those starting with 101x
(where x is a digit other than 1), then only 101 and 1011 need to be
provisioned as numbering plan entries on the NRS.

Procedure 5
Configuring the branch office
Step Action
1 Configure the Route List Index at the branch office.
After the call arrives at the branch office, a route must be provisioned
to handle the call. In order to be able to select a trunk to route calls,
a Route List Index (RLI) must be configured in the Route List Block
(RLB). The RLI uses the route number for PSTN trunk to route calls
to the PSTN. A Digit Manipulation Index (DMI) can be associated
with the RLI to allow manipulation of the digits to be outpulsed. For
this application, the DMI is used to remove the ZDP digits that were
inserted in the dialed digits at the main office. The DMI is also used
to convert the call type back correctly according to the incoming
SPN pattern.
a. Configure the DMI in LD 86 with the DGT feature.
LD 86 Configure Digit Manipulation Index at the branch office
Prompt Response Description
REQ NEW Add new data.
CUST xx Customer number as defined in LD 15
FEAT DGT Digit manipulation data block
DMI 1-999 Digit Manipulation Index numbers
The maximum number of Digit Manipulation tables is defined by
prompt MXDM in LD 86.
DEL (0)-19 Number of leading digits to be deleted.
This would normally be configured to remove the unique
non-dialable number that identifies the branch office, configured
in the ZDP property of the branch office zone in LD 117 at the
main office (step 2).
