BCM50 main unit

The BCM50 Main Unit (with telephony only) 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 four LAN ports: one is
the OAM port for technicians, and three are for basic LAN connectivity.

A Main Unit contains the following field-replaceable units:

• one programmed hard disk

• one cooling fan

• one router card (BCM50a, BCM50e, BCM50ba and BCM50be only)

Additional BCM50 hardware

The BCM50 expansion unit is a compact unit that accommodates the Media Bay Modules (MBM)
used by other BCM platforms. The BCM50 main unit can support a maximum of two expansion
units. For more information, see “BCM50 expansion unit and media bay modules” on page 18.

The wall-mount bracket is an inexpensive bracket for mounting the BCM50 or expansion unit to a
wall; for more information, see “Mounting kits” on page 19. An optional wiring card, which
provides RJ-45 connectors for all main unit trunk and station interfaces, is also available for use
with the wall-mount bracket.

The rack-mount shelf is an inexpensive shelf for mounting a maximum of
four BCM50 systems into a standard 19-inch rack. For more information, see “Mounting kits” on

page 19. An optional patch field that provides RJ-45 connectors for all main unit trunk and station

interfaces is also available.

BCM50e and BCM50a: BCM systems with integrated routers

BCM50 is available with an optional integrated ADSL or Ethernet router. These units suit the
needs of small businesses and small enterprise branch offices that require external data
networking, such as Internet access or VPN-based networking to other offices.

Two variations of the BCM50 have an integrated router, depending on th e WAN interface you
require: the BCM50e (Ethernet WAN) and, BCM50a (ADSL WAN). Both routers have the
following data features:

• secure Internet access

• multisite VoIP trunking using secure VPN tunnels

• wide-area VoIP applications with remote user support

• remote IP management and support using VPN clients

Common features and capabilities

BCM50a and BCM50e share the same functionality, which focuses on secure Internet access and
VoIP.

System Overview

14 Chapter 2 System Overview

BCM50e and BCM50a have three additional Ethernet LAN ports for a total of six LAN ports for
local premises use. All Ethernet ports are 10/100 Mb/s automatic sensing and support automatic
polarity. Therefore, you require no crossover cable to connect data hardware to the unit. An
additional port is provided for WAN access for, either Ethernet or ADSL.

The following features make BCM50a and BCM50e attractive for small sites that want to become
Internet-capable and multisite enterprises with many small sites. Until now, these sites could not
be part of the corporate WAN because of the high cost of traditional WAN connectivity and
managed service.

BCM50e

The BCM50e in Figure 3 provides call-processing and data-routing features and is suitable for
networks that require data-routing capability using an integrated Ethernet router. The WAN
interface port provides 10/100 Ethernet with automatic sensing and automatic polarity. If you have
existing or alternative WAN access technology, you can still benefit from the VoIP features of the
BCM50.

BCM50b, BCM50ba, and BCM50be: BCM systems with integrated BRIs

The BCM50 system provides private network and telephony-management capability to small and
medium businesses the EMEA and APAC markets. The BCM50 integrates voice and data
capabilities, IP telephony gateway functions, and data-routing features into a single telephony
system. The BCM50 is a compact system that you use to create and provide telephony applications
for use in a business environment.

Common features and capabilities

• BRI Compact Daughter Card (CDC)— Performance conforms to ITU I.430, ETSI ETS

300012, ANSI T1.605, and safety standards and lightening protection

• Additional CDC connector, for a total of two CDC slots

• Xilinx FPGA - XC3S400-4FT256C

• Integrated eight-port 10/100 Ethernet switch to support future eDSP CDC (upgraded from

five-port)

• 2.5 in. hard drive and new bracket

• Optimized position of fan cable, SATA cable, and hard-drive connector

• POL Current Limiting

• Introduce BRI and improve pack performance, and customer feature set.

• Memory parity

• Upgrade DSP and microprocessor

• GASI support

BCM50b

The BCM50b Main Unit provides functionality similar to the BCM50 main unit. The difference is
that the BCM50b main unit has two integrated BRI ports that replace the four analog lines on the
RJ-21 telephony connector.

BCM50ba

The BCM50ba Main Unit provides similar functionality to the BCM50a main unit. The difference
is that the BCM50ba main unit has two integrated BRI ports that replace the four analog lines on
the RJ-21 telephony connector.

BCM50be

The BCM50be Main Unit provides similar functionality to the BCM50e main unit. The difference
is that the BCM50be main unit has two integrated BRI ports that replace the four analog lines on
the RJ-21 telephony connector.

BCM50 expansion unit and media bay modules

You can expand BCM50 trunk and station capacity by connecting up to two external BCM50
expansion units. Expansion ports on the BCM50 are enabled through keycodes.

The expansion unit fits easily with the BCM50 and is easy to integrate and install using the
wall-mount and rack-mount accessories. The expansion unit connects to the BCM50 using an
RJ-45 CAT5 cable and uses its own external power supply, both of which are provided with the
expansion unit.

Each expansion unit can support one Media Bay Module (MBM) and, the same modules currently
supported in the BCM products. BCM50 supports the following Media Bay Modules:

• 4x16 Combo (4 analog trunks, 16 digital stations) — North America only

• 8x16 combo (8 analog trunks, 16 digital stations)

• ADID4 and ADID8 modules — North America only

• ASM8+ (8-port analog station interface) — North America only

• CTM4 (4-port CLID trunk module) — North America only

• CTM8 (8-port CLID trunk module) — North America only

• DTM (digital trunk module)

• BRI (ISDN Basic Rate trunk module)

• DSM16+ (16-port digital station module)

• DSM32+ (32-port digital station module)

• GATM4 (4-port global analog trunk module)

• GATM8 (8-port global analog trunk module)

• GASM8 (8-port global analog station module)
