Battery Backup Wiring Installation
The system can be equipped to operate from external batteries if local AC power fails. The
backup batteries are connected to the strip connector on the front of the PSU as shown:
Figure 3-32: Battery Back-Up Wiring
The external batteries must provide 24 Volts DC. This is generally accomplished by
connecting two 12-volt batteries per Cabinet in a series arrangement. Operation on batteries
is controlled by...

RS-232C Wiring on MPB and SIU
The MPB1 contains one and the MPB2 contains two standard RS-232C interfaces (SMC1 is
port 1 on MPB1 and MPB2; UART is port 5 on MPB2 only). The SIU on the MISB contains two
standard RS-232C interfaces (port 3 and port 4). The RS-232C is connected by a 9-pin
connector.

MISB Wiring
The MISB has connections for 2 music sources, 2 external page zones and 4 relay contact
controls. The MISB connections are made by the 25-pair connector. The wiring connections
for the 25-pair cable are identified inTable 3-4 on page 3-20.

Station Wiring
Station interface boards (DTIB24, ETIB, SLIB12) includes a 25-pair connector for station wiring
to the ports on the board. The following provides details on the interconnection of each type
of station interface board and the station jack.
Digital Keyset and Terminal Wiring
Wiring from the DTIB to station jack requires one-pair wire. Digitized voice, signaling, and
power are sent over this pair....

Electronic Keyset and Terminal Wiring
Wiring from the ETIB to station jack requires two pairs of wire. The first pair provides the
audio or voice path, the second is for signaling or data path. The DATA pair is polarity
sensitive. Reversal does not harm the keyset or system, but the port does not function
properly when reversed. Power is delivered by applying DC voltage to the center tap of the
coupling transformers of each of the 2 pairs.

Power Failure Transfer Unit Wiring
The Power Failure Transfer Unit (PFTU) is wired from the 25-pair connector to the MDF, cross
connected to the CO Line inputs from the telephone company, to the CO Line inputs of the
system, and to Power Failure SLTs. The basic connections are shown inFigure 3-40and the
connector configuration is given inTa b l e 3 - 1 9. Note that the SLT may also be connected to a
