Installing an analog station media bay module

You can connect a a maximum of eight analog telecommunication devices to the analog station media bay modules (ASM8, ASM8+, and GASM). 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] according to EIA/TIA 464)—indicates to the attached device, in an established communication, that the connected device must release the call
19
Note: When disconnect happens from the central office (CO), the ASM8+
provides an 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).
You must ensure that the device, application, or interface card connected to an ASM8+ station interface conform to these on-hook and off-hook conditions.
• 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 two REN/65 V rms per port.
• GASM8—designated as an on-premise station (OPS) port
The ASM8, ASM8+, and GASM each have one RJ-21 connector on the faceplate. Figure 1 on
page 20 shows the GASM faceplate.
Telephony Device Installation Guide
20 Chapter 3 Installing an analog station media bay module
Figure 1 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.
Refer to the following sections for information on installing and configuring an ASM:
• “Installing and configuring a media bay module” on page 20
• “Configuring the media bay module” on page 21
• “Wiring the ASM” on page 22
• “Installing analog devices” on page 22
For more detailed information on installing the BCM50 system and related components, refer to Installation and Maintenance Guide (NN40020-302).

Installing and configuring a media bay module

You can install media bay modules (MBM) in BCM50 main units and expansion units, depending on your system requirements.
The primary tasks to install an MBM are
• selecting an MBM for your system
• assigning DS30 resources
• setting MBM dip switches
• installing an MBM
For more detailed information on installing an MBM, refer to Installation and Maintenance Guide (NN40020-302).

Chapter 3 Installing an analog station media bay module 21

Configuring the media bay module

For information on installing a media bay module (MBM) and setting the dip switches, refer to the Installation and Maintenance Guide (NN40020-302).
To configure the MBM
1 Open Element Manager and connect to your BCM50 system.
2 Click Configuration > Resources > Telephony Resources.
The Telephony Resources panel appears (see Figure 27).
3 In the Modules table, select the location of the MBM that you want to configure.
4 Double-click the Programmed type field to display the drop-down list.
5 Select the type of MBM that you installed in that location.
6 Click Enable.
7 Repeat 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.

Wiring the ASM

An experienced installer can wire the ASM for your system using the wiring chart, for more information refer to the “ASM8, ASM8+, and GASM wiring chart” on page 65.

Installing analog devices

After the ASM is correctly wired, you can connect your analog devices.
Documentation describing how to install your analog devices and how to use their features, is supplied with each piece of equipment.

Installing the analog terminal adapter

This chapter provides installation instructions for the analog terminal adapter 2 (ATA2) or ATA.
The ATA2 connects a standard analog voice device or data communication device to the BCM50 system through a digital station module. Examples of analog voice devices are analog telephones and answering machines. Examples of analog data communication devices are modems and fax machines.
The ATA2 provides on-premise service only (protected plan wiring only).
Refer to the following topics for information on installing an ATA2:
• “Configuration overview” on page 23
• “Installing the ATA2” on page 24
• “Configuring the ATA2” on page 27
23

Configuration overview

The following sections describe environment configurations for connecting analog and data devices to the main unit using an ATA2:
• “Analog devices” on page 23

Analog devices

Figure 3 on page 23 shows an installation overview for connecting an analog device or analog data
device through an ATA2 to the BCM50 main unit.

Installing the ATA2

The following sections provide information on installing the ATA2:
• “Connecting the ATA2” on page 24
• “Mounting the ATA2” on page 25
• “Test insertion loss measurement” on page 25

Connecting the ATA2

After the correct environment has been set up, connect the BCM50 system and the analog device to the ATA2 and then connect the power (see Figure 4).

To connect the ATA2
1 Connect one end of a line cord to the ATA2 terminal jack.
2 Connect the other end of the line cord to your telephone, modem, or fax machine.
3 Connect one end of a second line cord to the ATA2 line jack.
4 Connect the other end of the line cord to an available station port on the BCM50 system.
5 For a 120-V or 230-V system, plug the DIN connector of the power supply cord into the power
supply connector receptacle.

Chapter 4 Installing the analog terminal adapter 25
6 Plug the adapter into a standard ac outlet.
Caution: In North America, the ATA2 must be powered from a Class 2 power source that
is UL- and CSA-approved.
In Europe, the ATA2 must be powered from a Class II power source that is CE-marked.

Mounting the ATA2

After you have correctly connected the ATA2, you can mount the unit on a wall.
To mount the ATA2 on a wall
1 Select a location for the ATA2 near the BCM50 main unit.
Note: If you are using 0.5 mm wire (24 AWG), select a location within
800 m (2600 ft.) of the BCM50 main unit.
2 Allow 12.5 cm (5 in.) clearance for the line jack, terminal jack, and power supply connector.
3 Screw two 4-mm (#8) screws into the wall, 130 mm (5-1/4 in.) away from each other. Leave
6 mm (1/4 in.) of the two screws showing.
4 Align the slots at the back of the ATA2 unit over the screws.
5 Push the unit against the wall.
The line jack, terminal jack, and power supply connector must be at the top of the ATA2 (see
Figure 6).

Test insertion loss measurement

The maximum loss for and ATA2-to-Central Office (CO) configuration must not exceed 10 dB (see Figure 7 on page 26).
Telephony Device Installation Guide
26 Chapter 4 Installing the analog terminal adapter
Figure 7 Insertion loss from the CO to the analog telephone
Longitudinal balance to ground 50 dB
Overload level 3 dB
Measure the total insertion loss between the CO and analog device by using standard dial-up test lines with a transmission test set (for example, Hewlett-Packard 4935A Transmission Test Set).
60 to 4,000 Hz With IEEE 455-1976 test
To measure the insertion loss from the CO to the analog device
1 Establish a connection to the 1 mW, 1 kHz, CO service line with an analog telephone attached
to the ATA2.
2 Ensure that the analog port terminates correctly in 600 ohms:
• Replace the analog telephone with the test set.
• Use RECEIVE/600 OHM/HOLD mode on the test set.
3 Ensure that the test set connects in parallel to the service line before removing the analog
telephone, or the line drops.
4 Remove the single-line telephone.
5 Measure the 1-kHz tone at the far end of the analog port, which is where the analog loop ends
and where the analog device connects.
Note: The tone must be greater than - 10 dB (for example, - 9 dB is acceptable).
