Hard-wire bridging
Analog type hard-wire bridging is not allowed for any DCP endpoints. Hard-wire bridging provides no
way of combining the digital output of two bridged DCP sets. Also, a bridged endpoint causes
degradation of the DCP signal.
CAUTION:
Bridging or paralleling these endpoints can cause electrical damage to the consoles or
cause the circuit pack to remove power from the consoles.
Dual wiring of 2-wire and 4-wire endpoints
Do not simultaneously wire a 2-wire and 4-wire endpoint to the same equipment location in an MDF. The
Avaya configurations use separate circuit packs to interface 2- and 4-wire endpoints.
Installing the attendant console
1
Install the attendant console and connect the modular cord to the information outlet.
2
Install labels per the attendant console form and the Display Module form assignments.
3
Install a digital line circuit pack in the assigned slot (if an additional circuit pack is required).
4
Administer the forms listed in “Attendant Console” in Administrator’s Guide for Avaya
Installing the 26B1 Selector Console
1
Connect the supplied 3-foot (1 meter) D8AC cable to the modular jack on the bottom of the 26B1
Selector Console.
2
Route the cable to the attendant console and connect to the DXS/BLF jack.
3
Attach labels according to the Attendant Console form.
4
Administer the console using Administrator’s Guide for Avaya Communication Manager.
Connecting external alarm indicators and
auxiliary power
Alarms can be generated on adjunct equipment, sent to the media server, and recorded and reported as
“external alarms.” A typical major alarm input is from an uninterruptible power supply (UPS).
The media gateway provides a relay contact that can operate a customer-provided alarm, such as a light
or bell. The circuitry and power source are customer-provided. The alarm device must not exceed a rating
of more than 100 volts at 0.75 amperes.
1
Connect 1 major and 1 minor alarm input pair to the trunk/auxiliary field from the AUX
connector. See
Table 21, Alarm Inputs at AUX Connector,
on page 210. Alarms can be generated
on adjunct equipment, sent to the Avaya media gateway, and recorded and reported as "external
alarms." The adjunct equipment must provide an isolated contact closure across the alarm leads
provided by the Avaya media gateway. The contact must be rated at a minimum of 60 VDC with a
current carrying capacity of 5 mA minimum.
2
Connect an external alarm output through pins 48 and 23 of the AUX connector. See
Table 22,
Alarm Output at AUX Connector,
on page 210.
