Optional Modem Data Port Modules 
(MDPMs)7.10 Digital 
keysets equipped with PC Data Port
Modules may be equipped with optional Modem Data
Port Modules (part no. 550.3015). The MDPM contains
a four-conductor modular jack that can be used to con-
nect a data device (such as a personal computer with a
direct-connect modem) or a single-line set to the 
keyset.
7.11The data device can be used by the associated
keyset to communicate with remote data equipment
over voice channels being used for CO or intercom calls.
The data device’s modem must be externally Powered
(or capable of operating on 20mA of loop current) and
have an 
RJll CO trunk interface.
7.12The data device can be activated by the asso-
ciated keyset or by an autodial modem. (For more
details and an explanation of transferring the data con-
nection, refer to page 4-101 in 
FEXWES). The data
device is disconnected whenever one of the following
occurs: the modem attached to the 
keyset disconnects
from the call, the called modem disconnects from the
call, or the data connection is transferred to the 
keyset’s
primary voice path and the call is disconnected.
7.13Install the Modem Data Port Module and attach
the data device as outlined below. For diagrams of theinstallation, see Figure 3-41 on page 3-69 and see Fig-
ure 3-42 below.

keyset line cord is unplugged
from its modular jack on the back of the keyset.
Plug the free end of the 
PCDPM-to-MDPM in-terface cable into connector 
Jl on the Modem
Data Port Module. (The other end of the cablewas previously attached to the PC’ Data Port
Module; see page 3-66.)
Insert the modem line cord (which would nor-
mally be connected to a CO jack) into the modu-
lar jack 
(52) on the Modem Data Port Module.Plug the AC transformer cable into the power
connector (Pl) on the Modem Data Port Module.
NOTE: MDPMs always require their own sepa-
rate AC transformers. For a diagram of 
ACtrans-
former requirements, refer to Figure 2-2 on page2-24.
Plug the main AC transformer unit into an avail-
able AC power source. DO 
NOT use the outlet
for the equipment cabinet.
Reconnect the 
keyset line cord.

IIWMLTATION
7.14Before installing the IMX 24/12&line analog
keysets, unpack each one and check for damage. If itemsare damaged or missing, contact Customer Support.
Each keyset should have the following:Baseplate
Extra key caps
One six-foot, three-pair line cord
One handset
One four-conductor coiled handset cord
Slide-out directory cardLiquid Crystal Display (LCD) Installation
7.15 
All AIM keysets (24line, 12-line, and &line)come equipped with 
LCDs. Standard 24-line and
12-line keysets can be converted to display keysets by
installing an LCD Kit as follows (see REPLACEMENT
PARTS for the part number):
(1)
(2)
(3)
(4Unpack the LCD Kit. There should be a clear
plasticdisplaywindow, anLCDunit, a foam pad,a ribbon cable, and two small Phillips-head
screws.Remove the 
keyset baseplate by removing the
retaining screw, pressing on the bottom edge of
the baseplate to release the tab, and pulling the
plate off.
Remove the line cord and handset cord 
from the
keyset. Then remove the four screws on the bot-
tom of the 
keyset.
Carefully open the 
keyset to expose the back of
the keyboard that has the LCD 
connector. (Refer
to Figure 3-43 on page 3-72.) To fully open the
keyset, the microphone and hookswitch wires(and Data Port Module wires, 
if attached) need to
be disconnected from the keyboard.
Remove the cover 
from the display opening inthetophousingofthekeysetbyreleasingthetabs
from the inside of the housing and pushing out
the cover.
From the 
front of the keyset, insert one end of the
clear plastic window in the display opening, with
the painted side of the black edging facing the in-
side of the 
keyset. Then slightly bend the win-
dow, insert the other end into the opening, and
ease the window into place.
Remove the covering 
from the LCD and install
as follows:
a.
b.
C.
d.Insert one end of the ribbon cable into the
black connector on the LCD unit. Ensure thatthe metal strips on the ribbon cable make
contact with the metal tabs in the black con-
nector.
With the LCD facing up, insert the other end
of the ribbon cable into the black connector
on the back of the keyboard. (Refer to Figure
3-43.)
Place the foam pad over the plastic windowso that the opening in the pad matches the
window.
Position the LCD on the plastic window so
that the screw holes in the LCD unit and inthe 
keyset housing are aligned. Check that
the foam padding does not show through the
window. Install the screws to hold the LCD in
place.
Reassemble the 
keyset. (Before closing the two
halves of the 
keyset, remember to reconnect the
hookswitch and microphone control wires. Also,if installed, reconnect the Data Port Module
wires.)

24/12/S-Line Keyset Installation
7.16Iustall all IMX analog keysets as follows:
(1)Before mounting the modular jack assembly and
connecting the 
keyset, measure the voltage on
the 
RED terminal of the modular jack assembly
with respect to the 
GREEN terminal. (I’he “com-mon” probe of the voltmeter is placed on the
GRBBN terminal.) It must measure +3OVDC
(f2.0VDC). If -30VDC is measured, check the
cabling for a reversed pair.CAUTION
If the power pair (W/BL, BL/W) is reversed, in-
stalling a keyset will open the fuse (or associated
thermistor) on the KSC or KSC-D. If the card has a
fuse, this affects operation of all 
keysets, DWBLFUnits, and Attendant Computer Consoles con-
nected to that card.
(2)Mount the modular jack assembly on the wall.
(3)Remove the 
keyset baseplate by removing the
retaining screw, pressing on the bottom edge
(1Zline and 24line keysets) or the top edge
(&line keysets) of the baseplate to release the
tab, and pulling the plate off.
(4)For b-line IMX AIM keysets that aw being in-
stalled 
two to a circuit: On the back of the keyset(see Figure 344 on page 
3-76), first place the
baud rate selection jumper strap (J9) in the 2400
position (over the left two pins). Then place the
circuit selection switch 
(Sl) in the appropriate A
(bottom) or B (top) position, depending on howthe 
keyset’s circuit will be designated in data-
base programming. (See also page 2-23 for spe-
cial line cord requirements.)NOTE: When 
8line IMX AIM keysets are in-
stalled two to a circuit, the circuit number is sep
arated into two parts (A and B) in database
programming (e.g., circuit 4.6Aand 4.6B). Also,
“B” circuit 8-line 
IMX AIM keysets do not haveextension numbers until assigned one in data-
base programming. If the switch selection does
not match the programming selection, the 
key-
set, when installed, will display CONFLICTING
s;aTCH SETTING and all of the LEDs
.
For 8-line IMX ALU keysets that anz being in-
stalled one to a 
circuit: On the back of the keyset
(see Figure 3-44 on page 
3-76), first place the
baud rate selection jumper strap 
(J9) in the 1200
position (over the right two pins). Then place thecircuit selection switch 
(Sl) in the A (bottom)
position.
(5)Attach the coiled handset cord to the handset and
to the handset jack on the right side of the 
bottom
of the keyset. Place the handset on hook.
(6)Plug one end of the line cord into the 
wall-
mounted modular jack assembly. Plug the other
end into the jack near the upper-left comer on the
bottom of the 
keyset.
NOTE: To aid in installation and troubleshoot-ing, display 
keysets show their station circuit
number, extension number, and assigned user
name for five seconds when power is turned on
and the line cord is first plugged in. This display
also appears after a system reset, and whenever
the line cord is removed and replaced while pow-
er is on. The station identification displays for
five seconds, then the 
keyset changes to the ap
propriate display, depending on its current status.
(7)Perform the 
keyset self-test:All non-AI’ 
Keysets:
a.While pressing the asterisk (*) and pound (#)

keyset line cord.
b.Release the keys. The

c.Lift and replace the handset to test the hook-
switch. The LED-equipped keys light and the

e.Press keys in the following order. A progress
tone is heard and the

ly if the key is functioning properly. If the sig-
nals are not heard, the key was either pressed
out of order or is faulty. Return the 
keyset for
repair if any key is faulty.
