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 the PSU. The PSU provides charging current to the batteries during normal
AC power operation at a maximum of about 1 amp. After connecting the batteries for
backup, ensure that you turn the BATT.SWITCH (located on the faceplate of the PSU) to the
ON position so that when AC power fails the batteries will automatically provide power.
During battery operation, the PSU discontinues battery operation if the AC power is
reapplied or the battery voltage is too low to maintain proper system operation. If a low-
battery cut-off occurs and a new battery must be installed, turn the BATT. SWITCH to the OFF
position, replace the battery, then turn the BATT.SWITCH to the ON position.
The length of time the system operates on the batteries is dependent on several elements
including: battery charge state, condition of the batteries, capacity of the batteries, and the
size of the system (number of station ports).
The following chart gives the approximate backup time for several system sizes and different
battery capacities in ampere-hours.

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.

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
SLIBasshowninthefigure.

Wall Mounting the Electronic Key Telephone
All connections to the Electronic Key Telephone are fully modular. To wall mount the
Electronic Key Telephone, it is necessary to have one Wall Mount Kit and one standard-type
jack assembly designed for normal wall hanging applications.
1. Unplug the line cord from the phone. This line cord is not be required and should be
retained as a maintenance replacement item.
2. Lift the plastic number retainer upward and expose the screw underneath. Remove the
screw and the handset tab. Replace it with the handset tab from the Wall Mount Kit.
3. Be careful to position the tab so that the protrusion faces the hookswitch. This allows the
handset to remain secure when the telephone is on the wall. Replace the screw and snap
the number retainer into place.
4. Substitute the short modular cord from the Wall Mount Assembly into the modular
connector vacated by the line cord.
5. Align the wall mount baseplate with holes on the bottom of the telephone. Snap in place.
6. Now match the two key hole slots on the baseplate with the lugs on the 630-A type jack.
Align the modular connector and slide telephone into place. Refer toFigure 3-41.

Wall Mounting the Digital Key Telephone
To wall mount the Digital Key Telephone, it is necessary to use the Wall Mount bracket and
one standard-type jack assembly designed for normal wall hanging applications. Refer to
Figure 3-41andFigure 3-42.
1. Remove the handset from the cradle and locate the plastic retainer in the bottom of the
hook-switch well area. Push the plastic retainer slowly upward until it is free. Locate the
tab on the plastic retainer and make sure the tab is toward you, then place it back into its
holder. Slide the plastic retainer all the way down into its channel. Part of the retainer
remains above its holder to hold the handset secure for the wall mount configuration.
2. Turn the telephone over and unplug the line cord. If the line cord is not plugged into the
wall jack assembly, re-route the line cord through the access channel on the top of the
telephone. If the line cord is plugged into the wall jack assembly, run the line cord
through the hole provided and plug into the connector on the back of the telephone.
3. Line up the hooks on the top and bottom of the wall mount bracket so they can engage
with the slots cut into the bottom of the telephone base. Insert the bottom hooks first.
Slide the mounting bracket slowly downwards until the top tabs slide into the top slots
and snap in place.

4. Match the two key hole slots on the base plate with the lugs on the 630-A type jack. Align
the modular connector and slide the telephone into place.
5. Place the handset onto the retainer. The telephone is now ready for use. Refer to
Figure 3-42for location of mounting information.
