Keyset Installation 
7.3 Ensure that the station loop resistance test has 
been performed before installing the keysets. 
7.4 Install all keysets as follows: 
(1) 
(2) Before mounting the modular jack assembly and 
connecting the keyset, measure the voltage on 
the BLACK (+28) terminal of the modular jack 
assembly with respect to the YELLOW (GND) 
terminal. (The “common” probe of the voltmeter 
is placed on the YELLOW terminal.) It must 
measure +2SVDC (f6.0VDC). If -28VDC is 
measured, check the cabling for a reversed pair. 
Check that there is no voltage across the other 
pair (on the GREEN and RED terminals). If there 
is voltage, trace the wires back to the KSU and 
correct the problem. 
CAUTION 
Incorrect voltage polarity will result in an inop- 
erative keyset.

the KSU AC power switch (PWR) to the OFF 
position to avoid shorting components while 
mounting the modular jack assemblies in the 
next step. 
Mount the modular jack assembly on the wall. 
Plug one end of the coiled handset cord into the 
jack on the left side of the keyset. Plug the other 
end into the handset. Place the handset on hook. 
(On GLX-Plus Keysets, you will first need to re- 
move the baseplate to expose the control board.) 
Plug one end of the keyset line cord into the mod- 
ular jack assembly. Plug the other end into the 
keyset jack labeled KSU. 
After all keysets are installed, turn the KSU AC 
power switch’(PWR) to the ON position. 
If installing a GLX-Plus Keyset, perform the 
self-test:

Optional Data Port Module For GLX-Plus Keysets 
7.9 GLX-Plus Keysets may be equipped with optional 
Data Port Modules (part number 828.1094). The Data 
Port Module contains a four-conductor modular jack 
that can be used to connect either a data device (such as a 
personal computer with a direct-connect modem) or an 
LRA and an external signaling device (such as a loud 
bell, horn, flashing light, etc.) to the keyset. 
7.10 Install the Data Port Module as outlined below. 
For a diagram, see Figure 3-17 on page 3-28.

(7) 
(8) 
Remove the keyset baseplate. 
Unplug the line cord fr&m its modular jack. 
Remove the lo-pin shorting plug located on the 
keyset control board. 
Save the shorting plug by taping it to the inside of 
the baseplate. The plug must be replaced if the 
Data Port Module is later removed. 
Align the Data Port Module over the three posts 
protruding from the inside of the baseplate and 
insert the screws (do not over tighten). 
Plug the Data Port Module cable into the pins on 
the keyset control board (where the shorting plug 
was previously located). Make sure the cable 
connector is securely seated. 
Place jumper straps SPl, SP2, SP3, and SP4 on 
the Data Port Module in the appropriate posi- 
tions. Depending on how the Data Port Module 
will be used, refer to one of the two possible set- 
tings outlined in Figure 3-17. 
If connecting a modem-equippeddata device, re- 
fer to paragraphs 7.11 through 7.13. If connecting a 
loud ringing adapter and an ex- 
ternal signaling akvice, 
refer to paragraphs 7.14 
through 7.16. 
7.11 To connect a modem-equipped data device: 
The optional Data Port Module on GLX-Plus Keysets 
and the ancillary jack (labeled DmA) on Executive 
Keysets can be used to connect a data device (such as a 
personal computer) equipped with a direct-connection 
modem to a keyset. The data device can be used with the 
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. 
7.12 The keyset is used to dial an outside or intercom 
number; the keyset user then presses the DATA key to 
connect the CO line or intercom channel to the data de- 
vice. While the data device is connected to a CO line or 
intercom channel, the keyset user cannot place or re- 
ceive calls. (For details on using the data connection, re- 
fer to page 4-10 in FEAXURES). 
7.13 
(1) 
(2) 
(3) 
Install the data device as follows: 
Insert the modem line cord (which would nor- 
mally be connected to a CO jack) into the modu- 
lar jack on the Data Port Module (or into the 
DATA jack on Executive Keysets). 
Ensure that the jumper straps on the Data Port 
Module are set to the proper data device posi- 
tions. Refer to Figure 3-17. 
Plug the keyset line cord into the keyset’s modu- 
lar jack and reattach the baseplate.

7.14 To connect a Loud Ringing Adapter (LRA): 
The optional Data Port Module on GLX-Plus Keysets 
and the ancillary jack (labeled DATA) on Executive 
Keysets can be used to connect external signaling equip- 
ment such as loud bells, horns, flashing lights, etc. to a 
keyset. This application is useful in areas where the nor- 
mal ring tone of the keyset cannot be heard, such as 
warehouses and loading docks. The signaling device 
follows the normal ringing patterns of the keyset. 
NOTE: Since handsfree intercom calls may be difficult 
to hear in noisy areas, keysets with LRAs installed 
should be programmed for ring intercom first so that 
users are alerted to incoming intercom calls by continu- 
ous ringing. (See FEAPURES, page 4-16.) 
7.15 An electromechanical LRA device is placed be- 
tween the keyset and the external signaling equipment 
to provide the necessary interface relay. Refer to page 
2-10 for LRA device specifications and recommenda- 
tions. A diagram of a typical set-up is shown in Figure 
3-18 
below. 
7.16 Install the LRA as follows: 
(1) Using 24AWG wire, connect the LRA device in- 
put (coil circuit) to the RED and GREEN wires 
on a modular jack assembly. Some devices re- (2) 
(3) 
(4) 
(5) 
(6) quire that polarity be observed between the LRA 
input and the modular jack. 
NOTE: In order for the LRA device to operate 
properly, the maximum resistance from the mod- 
ular jack to the LRA should be kept under 100 
OlUIlS. 
Attach a mod-to-mod line cord to the modular 
jack assembly and to the modular- jack on the 
Data Port Module (or DAPA jack on Executive 
Keysets). 
Ensure that the jumper straps on the Data Port 
Module are set in the proper LRA positions. Re- 
fer to Figure 3-17 on the previous page. 
Connect the LRA device output (contacts) to the 
signaling device according to the manufacturer’s 
instructions. Use the appropriate gauge wire for 
handling the current/voltage rating of the signal- 
ing device. 
Plug the keyset line cord into the modular jack on 
the back of the keyset and reattach the baseplate. 
While on hook, enter the LRAfeature code (#OS) 
to enable the LRA. (The display shows: LRA 
TOGGLED and the DAPA key is lit.) See page 
4-11 for additional information.

(e.g., relay) SIGNAL DEVICE 
(e.g., bell) 
NOTE: Each time the keyset rings, the Data Port Module provides 20-26mAof loop current to the LRA. This 
causes the LRA contacts to close and activates the signaling device. The LRA is not affected by the ring tone 
or the ringer volume of the keyset. The LRA must be capable of operating on 20mA current (approximately 
2OVDG).

B. SINGLE-LINE SET INSTALLATION 
7.18 Up to two industry-standard, AC-ringing, DTMF 
single-line sets may be connected to the KSU if the op- 
tional Accessory Port Module is installed. 
7.19 To install a single-line set: 
(1) Before connecting a single-line set to the system, 
measure the voltage on the RED terminal of the 
modular jack assembly with respect to the 
GREEN terminal. (The common probe of the 
voltmeter is placed on the GREEN terminal.) It 
must measure between -22VDC and -36VDC. If 
a positive voltage is measured, check the cabling 
for a reversed pair. 
(2) Mount the modular jack assembly on the wall. 
(3) Plug one end of the line cord into the modular 
jack assembly and plug the other end into the 
jack on the single-line set. 
8. EXTERNAL PAGING EQUIPMENT 
INSTALLATION 
8.1 A jack on the right side of the KSU is the output for 
the optional external paging equipment. Refer to Figure 
3-20 on the next page. Install the external paging equip- 
ment as follows: 
(1) 
(2) 
(3) 
(4) 
(5) 
(6) 
(7) Cut a length of shielded speaker cable (or coaxial 
cable) to run from the paging amplifier to the 
KSU. 
Attach a x-inch mini-phone plug to one end of 
the cable. 
Connect the other end of the cable to the ampliti- 
er high-impedance input according the manufac- 
turer’s instructions. 
Insert the plug into the KSU jack labeled E- 
PAGE. 
Connect the speaker(s) to the amplifier, using 
speaker cable. 
Plug in the amplifier’s AC power cord. DO NOT 
use the outlet for the KSU. 
Set the amplifier volume control to the lowest 
setting and turn on the amplifier. (8) From a keyset, make a page by lifting the handset 
and pressing the E-PAGE key. Adjust the ampli- 
fier to the desired level while placing the page. 
9. EXTERNAL MUSIC SOURCE 
INSTALLATION 
9.1 Ajack on the right side of the KSU is the input for 
the optional external music source (radio, tape player, 
etc.). Refer to Figure 3-20 on the next page. 
NOTE: In some circumstances, there may be broadcast 
restrictions associated with the music. Check with the 
music’s original distributor and/or the radio station for 
copyright and broadcast restrictions concerning back- 
ground music and music-on-hold. 
9.2 If using a radio as a music source, place it 5 to 10 
feet away from the KSU to avoid RF1 generated by the 
KSU. If the radio is placed more than 10 feet away from 
the KSU, use twisted-pair cable. For better reception, a 
radio with an external antenna is recommended. 
(1) 
(2) 
(3) 
(4) 
(5) 
(6) Attach the RCA-type phono plug to one end of a 
5 to IO-foot (1.5 to 3.0-meter) length of coaxial 
cable. 
EITFIER, connect the other end of the cable to 
the speaker output terminals of the music source. 
OR, if the music source has an earphone jack, at- 
tach an s-inch mini phone plug (or other speci- 
fied connector) to the other end of the cable, and 
plug it into the earphone jack on the music 
source. 
NOTE: If the earphone jack is “padded” so that 
the optimal volume level cannot be reached, the 
EITHER procedure may be more effective. 
Insert the phono plug into the KSU jack labeled 
MUSIC. 
Plug in the AC power cord for the music source. 
DO NOT use the outlet for the KSU. 
Turn on the AC power to the music source. 
From a keyset, select a CO line and dial the tele- 
phone number of one of the other lines to call 
back into the system. Put the call on hold to hear 
the music. Adjust the volume on the music 
source to the desired level. The optimum input 
level is l.OVRMS (OdB).
