Introducing the BCM50 hardware

The Business Communications Manager 50 Release 3.0 (BCM50 3.0) provides private network

and telephony management capability to small- and medium-sized businesses.

The BCM50 system:

• integrates voice and data capabilities, IP Telephony gateway functions, and data-routing

features into a single telephony system

• provides telephony applications for use in a business environment

• provides a DHCP enhancement feature for the main units with integrated router

Main units

The primary hardware component in the BCM50 system is the main unit. The six BCM50 main

units are divided into two series: standard and basic rate interface (BRI). The BRI (or b) series

main units include BRI ports that replace the four analog lines (on the RJ-21 telephony connector)

on the standard series.

• Standard series

— BCM50 main unit (with Telephony only)

The BCM50 main unit provides call processing and simple data networking functions. It

provides connections for 12 digital telephones, 4 (PSTN) lines, 4 analog station ports, and

4 connections for auxiliary equipment (auxiliary ringer, page relay, page output, and music

source). The BCM50 main unit has no router, but it has 4 LAN ports: one is the OAM port

for technicians, and the other three are for basic LAN connectivity. See the figure BCM50

main unit ports and connectors on page 39.

Note: The generic term “main unit,” used throughout this document, refers to any of the

six main units (BCM50, BCM50a, BCM50e, BCM50b, BCM50ba, and BCM50be)

available for a BCM50 system.

To indicate features specific to a particular variation of main unit, that variation of main

unit is clearly identified (for example, BCM50ba).
