BCM 4.0 Networking Configuration Guide

Chapter 2

System telephony networking overview

The system supports both public and private networking for telephony traffic.

• The public network is created by PSTN trunk connections from a Central Office terminating

on a telephone system such as the BCM.

• A private network is created when the system is connected through dedicated PSTN lines or

VoIP trunks to other systems. This system may take several forms. At the simplest level, your

system may be behind a private PBX, which connects directly to the Central Office. A more

complicated system may be a node in a network of systems of various types, where calls not

only terminate at the system, but calls may need to be passed through the system to other

nodes unconnected to the originating node.

Refer to the following topics:

• “Basic system configurations”

• “Private network parameters” on page 45

Basic system configurations

In the most basic application, your system can provide support for system telephones to make and

receive calls over public network (PSTN) lines.

Two basic system telephony configurations

The following provides a broad overview of the telephony setup for a PBX and a DID system.

PBX system

This setup is for a larger offices which have fewer CO lines than there are telephones. In this case

the lines are pooled, and the line pool access is assigned to all DNs. There may also be a

designated attendant with a telephone that has all lines individually assigned.
