Programming Operations Guide
Programming the PRI routing table
The dialing plan must be thoroughly planned out in advance before programming the information
into the Business Communications Manager system.
To program the routing table:
1
Click on the keys beside Services , Telephony Services , Call Routing , Routes .
2 Click on the route number record you want to use.
3
Beside External #: , type a dialout number (up to 24 digits).
If you are creating a route for a VoIP trunk, leave this field blank.
4
Under Use pool, select a PRI line pool.
The PRI pool(s) that are displayed depend on how you allocate PRI lines into pools in the
Trunk/Line Data section of line programming. It is possible to have only pool PRI-A, or only
pool PRI-B, or only pool PRI-C, etc., even if there are three DTMs configured as PRI in the
system.
5 Choose a service type or DN type, refer to the table below:
• Service type: displays for PRI lines with protocol set to NI-2, DMS100, DMS250, 4ESS.
Service ID:None appears where the service requires an ID.
• DN type: displays for PRI lines with protocol set to SL-1 (MCDN, ETSI Euro).
The following table lists the service/DN type choices available for PRI lines:
Enbloc dialing
Enbloc dialing allows the system to determine where a call should be routed on a PRI line. By not
dialing out until all digits are entered, the system looks at the entire code and can tell whether the
call should be routed through public lines, to another system on a network through private lines, or
to the local system.
Public and Private DN lengths and destination codes are used by the system to determine routing.
Any prefixes that need to be added on the dialed number, can be included in these settings.
