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.

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).

• 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.

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).

BCM50 Expansion unit and media bay modules

In addition to a main unit, the BCM50 system can have up to two BCM50 expansion units. An expansion unit connects to the main unit and provides additional functionality. For expansion unit port locations and descriptions, see the figure

BCM50 expansion unit connections on page 42 and the table BCM50 expansion unit ports, connectors, and descriptions on page 42.

The BCM50 expansion unit accommodates one media bay module (MBM) that connects additional telephony equipment to the BCM50 system. The MBMs connect with external devices to implement various types of voice trunks and stations. For a list of trunk and station MBMs that

can be used with your BCM50 system, see the table Trunk MBMs on page 45 and the table

Station

MBMs on page 47. For a complete list of MBMs with links to additional information, see also the

table Media bay modules on page 59.

The LAN port on the expansion unit is connected to the internal Ethernet switch on the main unit.

You can use the expansion unit LAN port to connect an additional device to the LAN.

Note: When you plug an expansion unit into the correct port on the main unit, the

LEDs on the expansion unit port light, while the LEDs on the main unit port turn off.



Note: When generating your keycode, you must select the feature for the expansion ports you require. If your keycode contains the feature for one expansion port only, the expansion port on the left (port 2) is active.

Media bay modules

The media bay modules (MBM) connect with external devices to implement various types of voice trunks and extensions. You can install one MBM in an expansion unit and you can connect up to two expansion units to the BCM50 system.

Note: To determine which media bay modules and which types of trunk lines are

available in your location, see Interface availability on page 245.

The back of the MBM has a single connector that provides signaling channels, media channels, and power to the MBM. This connector plugs into the MBM backplane in the expansion unit.

Some MBMs also have a cooling fan that operates using the MBM power source. The figure

Note: See Market profile attributes on page 245 for supported regions.

Digital trunk media bay module

The digital trunk media bay module (DTM) connects to a standard digital PSTN T1 or E1 carrier:

• On North American BCM50 systems, the DTM connects a T1 (24 channel) or PRI (23 channel) circuit to the BCM50. This PRI interface supports the NI-2 and MCDN protocol variants.

• On International BCM50 systems, the DTM connects a 30 channel PRI, DASS2, or DPNSS circuit to the BCM50. This PRI interface supports the ETSI Euro, ETSI QSIG, and MCDN protocol variants.

The front bezel of the DTM has an RJ-48C connector that connects the DTM to the service provider connection point. The faceplate also has a set of monitor jacks you can use to monitor the span.

Six additional LEDs are on the front of the DTM. For information about these additional LEDs,

see DTM LEDs on page 68.

The figure DTM faceplate on page 46 shows the DTM module interfaces.

Monitor jacks RJ-48C digital telephone line connector

Basic rate interface media bay module

The basic rate interface media bay module (BRIM) connects a maximum of four BRI ISDN loops to the BCM50 system. The BRIM recognizes only the T-interface used in European networks. To use the BRIM with the U-interface, typical in North American networks, you require an external

NT1 box to convert the U-interface to a T-interface.

Each BRI ISDN loop you connect adds two telephone lines to the BCM50 system. Therefore, each

BRIM adds a maximum of eight lines to the BCM50 system through the four RJ-48C jacks on the faceplate. The LEDs beside each RJ-48C jack are on when the ISDN line is active. The figure

BRIM faceplate on page 46 shows the BRIM faceplate LEDs and connections.

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.



• 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 50 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.

Wiring field card on page 54

Rack-mount shelf

To rack-mount a 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 52.

Figure 18 Rack-mount shelf installed in equipment rack

NN40170-305


Patch panel

The 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 53.

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 a 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 53.

Figure 20 Wall-mount bracket



Power supply mounting bracket and enclosure

There are two 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

BCM50. See the figure Wiring field card on page 54.

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.

Power supply

The power supply is an external device that connects to the BCM50 units. See the figure BCM50 power supply on page 55. You must have one power supply for each unit in your BCM50 system.

Figure 22 BCM50 power supply

To BCM50 unit

Power supply cord

Power supply cable (NA shown)

To wall outlet

A BCM50 power supply is included with each main unit and expansion unit.

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) 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 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 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 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.

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 57.

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

NN40170-305

Cooling fan

The main units have one cooling fan. The expansion unit has two cooling fans. See the figure

Cooling fan on page 57.

Figure 24 Cooling fan fan connector

The cooling fan mounts in the back of the 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

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 209):

• 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 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 BCM50 system uses the page relay to control the external paging amplifier.

• 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 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 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.

NN40170-305


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 BCM50 system to the Internet Service Provider (ISP).

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