BCM 4.0 Networking Configuration Guide

Guidelines for creating a private dialing plan with DPNSS

Use the following guidelines when creating a private dialing plan with DPNSS.

• When creating HLCs for the nodes in your system, avoid numbering conflicts between

network nodes and internal DNs, Hunt group DNs.

• Program a Private Access Code into your destination routing tables to avoid conflicts with

your internal HLC and dest code dialing plan. For example, if a dialout HLC is 848, but this

number already exists in the BCM system for an extension, the routing tables should add a

Private Access Code to the dest code. If the code is programmed as 6, the dest code becomes

6848. 6848 uses a route to dial out 848 using the DPNSS line pool, allowing the call to be

placed.

Note that a Private Access Code is required only for specific DPNSS features such as

Diversion, Route Optimization, and Redirection.

Customizing the DPNSS routing service

You can customize the routing service using the following restrictions:

• Direct Inward Access (DIA) lines allow incoming calls on private circuits to be directed to

telephones without going through the normal call reception. Each DIA line is assigned to one

or more extensions and is given a distinct Private Received number. When someone on another

system on the network dials the Private Received number on a DPNSS line, the BCM system

checks all received digits, compares the digits to an internal table and routes the call to the

appropriate DIA line. All extensions programmed to have access to that DIA line will then

alert for the incoming call.

• Dialing restrictions can be added to lines in line pools. Filters can restrict the use of the line to

specific area codes.

• You can use host system signaling codes ( “External call codes” in the BCM 4.0 Device

Configuration Guide (N0060600)) as part of the dial out for a route. Routing can also be used

as an alternate method for a direct-dial digit. For example, create a destination code 0 and

program the number of the internal or external destination as the dial out. Digit absorption

should be set to 1. Because overflow routing directs calls using alternate line pools, a call may

be affected by different line restrictions when it is handled by overflow routing
