Adjunct Power
Power for several of the adjuncts must be provided locally at the voice terminal or
from a satellite closet through the terminal wiring. The following power supplies
are currently recommended:
nThe 1151A1 Power Unit and the 1151A2 Power Unit with Batter y Holdover
have replaced the MSP-1 (WP92464L1) Power Supply, the KS-22911 L1/2,
329A, and 353A DC power supplies, and the 2012D AC transformer. The
1151A1 and 1151A2 with Battery Holdover can be used to supply local
power to ISDN-T 65xx, 75xx, and 85xx series voice terminals connected to
a DEFINITY Communications System Generic 1, Generic 2, Generic 3, a
DEFINITY ECS, and the DCP 7444 and 8434/8434DX voice terminals
which need auxiliary power for their vacuum fluorescent displays. You will
also need auxiliary power if you are using a 6400 Series telephone or an
8411 voice terminal or if you have a ZE801A or an XM24 expansion
module connected to your voice terminal or telephone. These power units
can also supply auxiliar y power to adjunct equipment such as the S201A,
CS201A, or SoundPoint speakerphones or a 500A1 Headset Adapter
attached to any currently manufactured analog, DCP, or ISDN-T voice
terminal equipped with an Adjunct jack. For more information on the MSP-1
and the newer 1151A1 and 1151A2 power supplies, see the shor t section
with connection diagrams later in this section.
nThe ISDN 1145B1 Bulk Power Unit, 1146B Power Distribution Unit, and the
2.5/5.0 A.H. back-up batteries provide an uninterruptible power source for
ISDN telephones and terminals, NT1s, terminal adjuncts, and other
customer premises equipment. During AC power interruptions, batteries
are automatically switched on to provide continuous power to the load.

The distribution of power to the terminal equipment is provided by the
1146B distribution unit. The 1146B provides 32 standard 110 connections
to the load with overcurrent protection and alarm lights. The 1145B1/1146B
power arrangement is compact (measuring only 6.5 inches deep),
lightweight, plastic enclosed, and designed for easy wall- or rack-mounting.
During normal operation, the power supply/charger provides DC power to
the load via the distribution unit while maintaining the battery in a fully
charged condition. The power system continuously monitors systems
conditions with the status displayed on the front panel of the power supply
and distribution unit.
The following power supplies and transformers are NO LONGER recommended.

One of these power supplies must be used for each voice terminal equipped with
one or more adjuncts. Each of these power supplies (except the 95B1) has a
maximum cable distance of 250 feet (76 m) between the power supply and the
adjunct(s). The maximum cable distance for the 95B1 is 150 feet (45m). Voice
terminal adjuncts and modules are not operational during interruptions of
commercial AC power unless their power supplies are also powered through
standby power of other essential AC power service.
The 329A and 346A power supplies clustered in a satellite closet are normally
mounted on AC power strips. Power to these strips is provided from a dedicated
120 volt AC, 60-Hz, 20-ampere circuit breaker and feeder either directly or
through a 543A telephone power unit. The 543A unit provides an inductive filter to
limit inrush current on the feeder. It comes equipped with an AC power cord which
plugs into the dedicated feeder and provides four receptacles for AC power strips.
The 945 bulk power system is usually rack mounted and is intended to be located
in an equipment room or satellite closet. It is optionally made up of the following
components:
n945-1 bulk power supply unit.
n945-2 batter y reserve unit.
n945-3 system enclosure, equipped with one or two 945-1 and/or a 945-2.
n945-4 single enclosure for 945-1 unit.
Several power supplies and connection schemes are available for providing
auxiliary adjunct power when it is required. Regardless of its source, auxiliary
power is introduced into a pair of spare leads in the individual voice terminal’s line,
at some wiring interface. The auxiliary power is fed into the terminal on the
mounting line cord. From the terminal, power is distributed to the adjunct(s). An
auxiliary power source is usually mounted in a satellite closet or adjacent to the
voice terminal’s wall jack.
The MSP-1 Power Supply
The MSP-1 (WP92464L1) Power Supply can be used to supply local power to
ISDN-T 65xx, 75xx, and 85xx series voice terminals connected to a DEFINITY
Communications System G1, G2, and G3, a DEFINITY ECS, and to the DCP
7444 and 8434/8434DX voice terminals which need auxiliary power for their
vacuum fluorescent displays. The MSP-1 can also supply auxiliary power to
adjunct equipment such as the S201A and CS201A speakerphones or a 500A
Headset Adapter attached to any currently manufactured analog, DCP, or ISDN-T
voice terminal equipped with an Adjunct jack.
!CAUTION:
The MSP-1 Power Supply can be used only with telecommunications
equipment, indoors, in a controlled environment.
