Installing an analog station media bay module (ASM)
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 kbit/s.
The ASM8 is available in North America only; the ASM8+ and GASM8 are available in North
America, the United Kingdom, Australia, and Poland.
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.
• Disconnect supervision (Open Switch Interval [OSI] as per EIA/TIA 464) — indicates to the
attached device, in an established communication, that the connected device should release the
call (see disconnect supervision note).
• 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 — allows the system to 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.
• Calling line identification (CLID)
• The GASM8 is designated as an ONS (on-premise station) port.
The ASM8, ASM8+, and GASM each have one RJ-21 connector on the faceplate. Figure 26
shows the GASM.
Disconnect supervision note: When disconnect happens from the central office,
the ASM8+ provides an open switch interval (OSI) to the off-hook station of 850
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 to it (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).
It is important to ensure that the device, application, or interface card connected to
an ASM8+ station interface conform to these on-hook and off-hook conditions.

The ringer equivalency number (REN) per port for ASM8 is 1; the REN for ASM8+ and GASM
is 2.
Refer to the following for information on installing and configuring an ASM:
•“Configuring the media bay module” on page 66
•“Wiring the ASM” on page 67
•“Installing analog devices” on page 68
For more detailed information on installing the BCM system and related components, refer to
BCM200/400 4.0 Installation and Maintenance Guide (N0060612).
Configuring the media bay module
For information on installing a media bay module (MBM) and setting the dip switches, refer to the
BCM200/400 4.0 Installation and Maintenance Guide (N0060612).
To configure the MBM
1Open Element Manager and connect to your BCM system.
2Click Configuration > Resources > Telephony Resources.
The Telephony Resources panel appears (see Figure 27).
3In the Modules table, select the location of the MBM that you want to configure.
4Double-click the Programmed type field to display the drop-down list.
5Select the type of MBM that you installed in that location.
6Click Enable.
7Repeat steps 4 to 7 to enable each MBM in your system.
You can set other parameters for the MBMs depending on the type of MBM you installed.
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.
