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)

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 an Avaya BCM50 system.
To indicate features specific to a particular variation of main unit, that variation of main
unit is clearly identified (for example, BCM50ba).

The Avaya 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.

Analog station media bay modules

The analog station media bay modules (ASM8, ASM8+, and GASM) can connect to a maximum
of eight analog telecommunication devices. These devices are standard analog telephones,
cordless telephones, fax machines, answering machines, or modems. The maximum speed for a
modem connection is 28.8 Kb/s.

In addition to ASM8 features, the ASM8+ and GASM offer the following features:

• Visual Message Waiting Indicator (VMWI): LED indicates to the end user that a message is
waiting.

• Caller ID: provides the name, phone number, and other information about the caller to the end
user at the start of the call.

• Firmware downloading capability: The core can upgrade the ASM8+ and GASM firmware at
customer sites.

Installation and Maintenance Guide

44 Chapter 2 Introducing the Avaya BCM50 hardware

• Enhanced ringing capability: ASM8+ and GASM provide a ringing voltage of 2 REN/65 V
rms per port.

• The GASM8 is designated as an on-premise station (ONS) port. This device provides
telecommunications ringing voltages and can be configured to provide voltage message
waiting indicator (VMWI) voltage levels. Installation of this device and all connections to this
device must be performed by qualified telecommunications service personnel who are aware
of the hazards associated with telecommunications wiring and are aware of the local
regulations for treatment of telecommunications wiring for ONS deployment.

• Disconnect supervision (Open Switch Interval (OSI) as per EIA/TIA 464): indicates to the
attached device, in an established communication, that the connected device releases the call.

Disconnect supervision note: When disconnect happens from the Central Office
(CO), the ASM8+ provides an open switch interval (OSI) to the off-hook station of
850 milliseconds (ms) (TIA/EIA 464 section 5.4.10.2.4, minimum is 600 ms) as a
disconnect signal. If the station remains on-hook after the disconnect signal, the
ASM8+ disconnects the station equipment from the network without returning a
tone (TIA/EIA 464 section 5.4.10.2.5[1]). After the station equipment goes
on-hook, the ASM8+ station interface is restored to on-hook (idle).

You must ensure the device, application, or interface card connected to an ASM8+
station interface conforms to these on-hook and off-hook conditions.

The ASM8, ASM8+, and GASM each has one RJ-21 connector on the faceplate. The figure

GASM faceplate LEDs and connectors on page 44 shows the GASM.

Figure 17 GASM faceplate LEDs and connectors

The ringer equivalency number (REN) (per port) for ASM8 is 1; the REN for ASM8+ and GASM
is 2.

Note: The termination of the analog interface can consist of any combination of devices,
subject only to the requirement that the sum of the RENs of all the devices does not exceed
the REN of the interface to which the device is connected.

Stutter Tone/
Reverse polarity/
Voltage MWI
(PBX: 90 V)

N/A

To rack-mount a Avaya BCM50 unit (main unit or expansion unit), you need a rack-mount shelf.
The rack-mount shelf mounts in a standard 19-inch equipment rack. The BCM50 unit then clips
into the tabs on the rack-mount shelf. These tabs prevent the unit from sliding or falling off the
shelf.

If the BCM50 system includes additional units, you can clip another unit to a second set of tabs on
the rack-mount shelf. You can clip additional units to tabs on the top of the other units. See the
figure Rack-mount shelf installed in equipment rack on page 46.

Figure 18 Rack-mount shelf installed in equipment rack

NN40170-305

Patch panel

The Avaya BCM50 patch panel simplifies the connections of lines and extensions to the main unit.
The BCM50 patch panel installs into the rack-mount shelf in a standard equipment rack and
connects to the RJ-21 telephony connector with a user-supplied RJ-21 cable. See the figure Patch

panel connectors on page 47.

Note: The four analog lines on the patch panel are only available with the standard main
units. The four analog lines are not available with the BRI series (b-series) main units.

Wall-mount bracket

To wall-mount an Avaya BCM50 unit (main unit or expansion unit), you need a wall-mount
bracket. The wall-mount bracket is attached to the wall, and the unit is connected to the
wall-mount bracket. If the BCM50 system includes additional units, you need a wall-mount
bracket for each unit.

Each wall-mount bracket includes a cable-management tray that you use to store and organize the
cables connected to the BCM50 units. See the figure Wall-mount bracket on page 48.

Installation and Maintenance Guide

48 Chapter 2 Introducing the Avaya BCM50 hardware

Figure 20 Wall-mount bracket

Power supply mounting bracket and enclosure

There are two Avaya BCM50 power supply mounting options that enable you to install your
power supply units next to your BCM50 system and keep the power cables neatly organized:

• Power supply mounting enclosure — accommodates up to three power supplies in a case that
is similar in size and shape to a BCM50 unit. You can install the power supply mounting
enclosure in the same way as BCM50 unit (in a rack, on a wall, or on a desktop).

• Single power supply mounting bracket — accommodates a single power supply for
wall-mount applications.

Wiring field card

The wiring field card (WFC) simplifies the connections of lines and extensions to the main unit.
The WFC installs into the cable-management tray of the wall-mount bracket and connects to the
RJ-21 telephony connector through a 50-pin header.

The WFC contains 12 eight-pin modular jacks for digital stations, 4 eight-pin modular jacks for
analog trunks, and 4 eight-pin modular jacks for analog stations. The eight-pin modular jacks
accept RJ-45 or RJ-11 modular plugs.

A terminal block is available to connect auxiliary equipment. A 50-pin header connects to the
Avaya BCM50. See the figure Wiring field card on page 49.

NN40170-305

Note: The four analog lines on the WFC are only available with the standard main units.
The four analog lines are not available with the BRI series (b-series) main units.

In addition, international (non-North American) users require a power supply adapter cord for
each main unit and expansion unit.

Power supply adapter cord (international users)

The power supply adapter cord is for international (non-North American) Avaya BCM50 users.
The cord connects to the power supply on one end and to the (C-14) BCM50 power bar on the
other end.

You require one power supply adapter cord for each power supply you want to connect to the
power bar.

Uninterruptable power supply

An uninterruptable power supply (UPS) is an optional device that maintains continuous operation
during a power interruption or failure. The UPS provides power source monitoring and battery
backup activation so that critical BCM50 functionality is maintained.

During a power failure, the UPS provides sufficient time to either correct the problem or activate a
contingency plan to sustain services. The UPS performs a graceful shutdown of the Avaya BCM50
two minutes before the UPS battery power is drained.

The BCM50 supports American Power Conversion (APC) UPS devices that use a USB control
interface. The APC UPSs include the APC UPS-Smart family (for example, UPS-Smart 750 and
UPS-Smart 1000) and UPS-Back family (for example, UPS-Back 500 ES and UPS-Back 350 ES).
You can use the UPS control software to configure various operational settings.

Note: For the UPS to function correctly, you must connect it before you power up
the Avaya BCM50 system. If you connect a UPS to a running system, the UPS
does not function.

The USB port on the UPS uses a different communication speed than the USB port on the BCM50
system. Due to this difference, you must use an industry-standard USB hub (USB 1.1-compatible)
to connect the UPS data connection to the BCM50 system. The USB hub not only provides
additional USB ports, it converts the data communication speed so the UPS and BCM50 system
can communicate properly.

On Avaya BCM50 systems with more than one unit, you must connect the power supplies for all
the units must to a single UPS.

The interaction between the UPS and the BCM50 occurs in three stages:

1 Configuration—This stage sends configuration information to the UPS device and requires

minimal user interaction.

2 Monitoring—This stage is a steady-state, periodic monitoring cycle where the BCM50 reads

the status of the UPS. This stage requires minimal user interaction.

3 Failure condition—This stage initiates an action when a threshold value is surpassed.

NN40170-305

Chapter 2 Introducing the Avaya BCM50 hardware 51

The BCM50 system requires user interaction in the case of a planned system shutdown. You must
manually power down the UPS and the BCM50 main unit when performing a system shutdown.

The UPS feature is supported in all markets (110~120V and 220~240V power standards).

Hard disk

Each main unit contains a single hard disk and a hard disk bracket to install it in the main unit. See
the figure Hard disk and bracket on page 51.

For installation and replacement instructions, see Replacing an internal component on page 195.

The cooling fan mounts in the back of the Avaya BCM50 enclosure.

For information about how to install or replace the cooling fan, see Replacing an internal

component on page 195.

RJ-21 telephony connector

fan connector

Use the RJ-21 telephony connector to connect a 25-pair (RJ-21) cable to the main unit. Then use
these 25 pairs of wires to connect to the following telephony devices (see RJ-21 telephony

connector wiring chart on page 215):

• Four analog lines (standard main units only)
Use these connections for analog trunks from the Public Switched Telephone Network
(PSTN). The four analog lines on the RJ-21 telephony connector are not available on the BRI
series (b-series) main units.

• Four analog telephones
Use these connections for analog telephony devices such as single-line telephones, fax
machines, and modems.

• Auxiliary ringer
Use this connection for an auxiliary ringer (customer supplied). The Avaya BCM50 system
uses the auxiliary ringer to control the cadence of an auxiliary ringer. You must use this output
in a low-current, low-voltage application only. Do not use this output for switching the
auxiliary ringer directly.

• Page output
Use this connection to connect an internally generated voice-paging signal to an external
paging amplifier (customer supplied).

• Page relay
When you use the page output to connect an external paging amplifier, you also use the page
relay. The page relay connects to a floating relay contact pair. The Avaya BCM50 system uses
the page relay to control the external paging amplifier.

NN40170-305

Chapter 2 Introducing the Avaya BCM50 hardware 53

• Music input
Use the Music input to connect an external music source that supplies a signal to held lines
(music on hold) or telephone speakers (background music). The input source can be any
available radio or music source approved for connection to the network. If you use this
connection, do not use the Music input jack on the main unit faceplate.

• Twelve digital telephones
Use these connections for digital telephones. For a list of digital telephones that are compatible
with the Avaya BCM50 system, see the Telephony Device Installation Guide.

Warning: External equipment connected to the auxiliary ringer, page relay, page output,
and music-on-hold interfaces must use safety extra low voltage (SELV).
All four interfaces are SELV and the external equipment connected to these interfaces
must be SELV. If these interfaces are not SELV, you must use external line isolation units
(LIU).

Note: The analog trunk interfaces and analog telephony device interfaces on the RJ-21
telephony connector are compatible with the North American telephony interface
standards only.
If your Avaya BCM50 system is in a country that uses a different telephony standard, you
must use media bay modules for your analog trunks and media bay modules or ATAs for
your analog telephony devices.

Router card

The BCM50e main unit has a router card that uses an Ethernet interface to connect to a WAN edge
device (for example, an external ADSL modem or a cable modem).

The BCM50a main unit has a router card that uses an ADSL interface to connect the Avaya
BCM50 system to the Internet Service Provider (ISP).

For information about replacing the router card, see Replacing an internal component on page 195.

Field-replaceable units

The table Field-replaceable units on page 54 and the table Media bay modules on page 54 provide
a list of field-replaceable units (FRU) and media bay modules (MBM) for the Avaya BCM50
system. Use these tables as references when you need to order, replace, or install hardware
components. The tables provide references to the component descriptions and installation
procedures.

Chapter 4 Determining DHCP server configuration and IP address 65

Chapter 4

Determining DHCP server configuration and IP address

Each main unit has a dynamic host configuration protocol (DHCP) server. This DHCP server

supplies Avaya IP Deskphones and client computers with IP addresses and connection
information.

If the main unit has no integrated router, then you can configure the DHCP server using Business
Element Manager.

If the main unit has an integrated router, then you can activate either the DHCP server on the main
unit or the DHCP server on the integrated router. If you want to use the DHCP server on the main
unit, you must first disable the DHCP server on the integrated router.

For more information about configuring the DHCP server, see the procedure To configure DHCP

server settings on page 139.

The Avaya Business Communications Manager 50 (Avaya BCM50) system can have a main unit
with or without an integrated router:

• Avaya BCM50 and Avaya BCM50b main units (no integrated router) on page 65

• BCM50a, BCM50ba, BCM50e, and BCM50be main units (with integrated router) on page 66

Avaya BCM50 and Avaya BCM50b main units (no integrated router)

By default, the main unit is configured with a dynamic IP address, which means the IP
configuration is received from a DHCP server.

The BCM50 and BCM50b main units can have two DHCP server configurations:

• If an external DHCP server is not present on page 65

• If an external DHCP server is present on page 66

If an external DHCP server is not present

If an external DHCP server is not present, then the main unit uses the following default IP
configuration:

IP address:

Subnet mask:

192.168.1.2

255.255.255.0

Gateway:

192.168.1.1

Installation and Maintenance Guide

66 Chapter 4 Determining DHCP server configuration and IP address

The DHCP server on the main unit supplies IP configuration information for all IP devices (PCs
and IP Deskphones). The DHCP server also supplies specific connection information to the IP
Deskphones.

If an external DHCP server is present

Warning: The DHCP server on the main unit is enabled (IP Deskphones only) by

default. If your network already contains a DHCP server, then disable the DHCP
server on the main unit. For more information about disabling the DHCP server
on the main unit, see the procedure To configure DHCP server settings on page

139.

If an external DHCP is present, then the Avaya BCM50 system uses the IP configuration supplied
by the external DHCP server. In this case, the DHCP server on the main unit supplies only IP
Deskpones with IP configuration information. The DHCP server on the main unit does not supply
any other devices with IP settings. This means that the administrator need not set up the external
DHCP server to supply configuration settings to the IP Deskphones.

The DHCP server on the main unit must configure a range of IP addresses to supply to the
IP Deskphones. The DHCP server uses the top 20 percent of a subnet.

For example, if the external DHCP server supplies the IP address 177.218.21.45 (subnet mask is

255.255.255.0) to the Avaya BCM50, then the BCM50 DHCP server reserves the range

177.218.21.200 to 177.218.21.254.

You can verify and change this default range using Business Element Manager.

The administrator must ensure that this range agrees with the network configuration—the external
DHCP server does not use the range.

BCM50a, BCM50ba, BCM50e, and BCM50be main units (with integrated router)

You can select the DHCP server option to use with the Avaya BCM50 integrated router main
units. You can select to use the integrated router or you can disable the integrated router and use
the DHCP server that is on the main unit. Select the DHCP server option through Business
Element Manager (Configuration > Data Services > DHCP Server > General Settings tab).

If you select the standard DHCP server on the main unit, you must first disable the DHCP server
on the integrated router. You can then configure the DHCP server functionality in the same way as
a non-router version.

If you select the DHCP server on the integrated router you can configure the router using the router
WebGUI tool.

NN40170-305

Chapter 4 Determining DHCP server configuration and IP address 67

By default, the integrated router is selected and you configure the BCM50a, BCM50ba, BCM50e,
and BCM50be main units with a dynamic IP address, meaning that these units request an IP
configuration from a DHCP server. Because the integrated router has a DHCP server, this DHCP
server responds to the request.

By default, the router LAN IP address is 192.168.1.1, and the IP address assigned to the Avaya
BCM50 system is the first IP address in the DHCP pool. If the DHCP pool starts at 192.168.1.190,
then the BCM50 is 192.168.1.190 even though the router is 192.168.1.1. Therefore, the Avaya
BCM50 system receives the IP address 192.168.1.2 (subnet mask is 255.255.255.0) from the
DHCP server on the integrated router.

The DHCP server on the integrated router supplies the information (primary and secondary TPS
server information, VLAN IDs) to the IP Deskphones enabling the phones to connect to the
BCM50. If the IP address of the integrated router changes, then the IP address reserved for the
BCM50 automatically changes. The DHCP server on the integrated router automatically updates
the S1 and S2 IP address.

For more information about configuring a DHCP server for your Avaya BCM50 main unit, see the
procedure To configure DHCP server settings on page 139.

Installing the Avaya BCM50 unit in an equipment rack

You can install an Avaya Business Communications Manager 50 (Avaya BCM50) main unit in a
standard 19-inch equipment rack along with your other networking and telecommunications
equipment.

To rack-mount an Avaya BCM50 unit, you need the optional rack-mount kit (NT9T6325). This kit
provides the parts to mount up to four BCM50 units into a standard 19-inch equipment rack. The
BCM50 unit mounts into the tabs on the rack-mount shelf. These tabs prevent the unit from sliding
around or falling off the shelf. If the BCM50 system includes additional units, you can mount
another unit onto a second set of tabs on the rack-mount shelf. You can mount any additional units
to tabs on the top of the other units.

If you need to better secure a BCM50 unit, use the screws provided (four per unit) to screw the
BCM50 to the rack. This is a “hardened” installation. For a hardened installation, install only two
units per rack—do not stack the units.

You can also use the optional patch panel to simplify the connections to the BCM50 RJ-21
telephony connector.

Installing the Avaya BCM50 unit on the wall

To wall-mount an Avaya BCM50 unit, you need a wall-mount bracket. The wall-mount bracket
attaches to the wall, and the BCM50 unit connects to the wall-mount bracket. If the BCM50
system includes additional units, you need a wall-mount bracket for each unit. Each wall-mount
bracket includes a cable-management tray that you use to store and organize the cables connected
to the BCM50 units. An optional wiring field card simplifies the cable connections for the lines
and extensions.

If desired you can install an optional plywood backboard 2 cm (3/4 in.) thick.

Caution: For acceptable environmental conditions before selecting a location for the
BCM50, see Checking the installation prerequisites on page 73.

Caution: You must mount Avaya BCM50 units side-by-side on the wall. DO NOT
attempt to mount units on top of each other when using the wall-mount option.

Caution: To keep the BCM50 operating at the optimal internal temperature, keep the top,
sides, and rear clear of obstructions and away from the exhaust of other equipment.

Use the following procedures to install the Avaya BCM50 unit on a wall:

• To install the Avaya BCM50 wall-mount bracket on page 83

• To install the Avaya BCM50 unit on the wall-mount bracket on page 84

Chapter 7 Installing the main unit 83

To install the Avaya BCM50 wall-mount bracket

1 Use a pencil to mark the location of the plywood backboard on the wall. Use a ruler and a level

to make sure that the plywood backboard is level.

Note: Avaya recommends the use of a plywood backboard to simplify installing
multiple Avaya BCM50 units. However, due to the compact size and light weight of
the BCM50 units, a backboard is not required.

If you do not use a backboard, use the appropriate wall anchors or ensure the screws
are in a stud.

2 Mount the plywood backboard securely to the wall.

3 Place the wall-mount bracket on the backboard and mark the location of the center

keyhole-shaped screw hole on the plywood backboard. See the figure Wall-mount bracket on
page 83.
