4.1 
The system capacity for stations is as follows: 
Total Station Instruments 12 Keysets 1-12 
Single-Line Sets o-2 
B. KEYSETS 
4.2 The following keyset models are available: 
l Standard Keyset 
l Executive Keyset 
l GLX-Plus Keyset (display and non-display) 
NOTE: The GLX-Plus Keyset is supported only on 
KSUs equipped with the current 827.4012 software. 
4.3 For illustrations of the keysets (showing feature 
keys, CO line keys, and DSS/BLF keys), refer to the 
drawings beginning on page 2-14. 
4.4 The Standard and Executive Keyset dimensions 
are: 
Height 3.5 in. (8.9 cm.) 
Width 7.5 in. (19.0 cm.) 
Depth 9.0 in. (22.9 cm.) 
Weight 2.5 lb. (1.1 kg.) 
4.5 The GLX-Plus Keyset dimensions are: 
Height 3.8 in. (9.7 cm.) 
Width 7.0 in. (17.8 cm.) 
Length 9.5 in. (24.1 cm.) 
Weight 2.5 lb. (1.1 kg.) 
4.6 All keysets have the following design features: 
1Zkey pushbutton keypad 
Feature keys (6 on Standard Keysets, 12 on Execu- 
tive Keysets, and 12 on GLX-Plus Keysets) 
Integrated (built-in) speakerphone 
Ring and voice volume controls 
Slide-out directory card 
Reversible baseplate for wall mounting 
Hearing aid-compatible (HAC) handset 
NOTE: GLX-Plus Keysets and handsets have been de- 
signed using “electret” microphone circuitry, rather 
than the “dynamic” microphone circuitry used on Stan- 
dard and Executive Keysets. Both types of keysets can 
be used together on the GLX-Plus System. However, if a dynamic handset is attached to an electret keyset, the 
handset transmit levels will be noticeably lower. If an 
electret handset is attached to a dynamic keyset, the 
handset will not transmit. 
4.7 Besides the features listed after paragraph 4.6, 
Executive Keysets and GLX-Plus Keysets have the fol- 
lowing additional features: 
l 12 Direct Station Selection/Busy Lamp Field (DSS/ 
BLF) keys with light-emitting diode (LED) indica- 
tors 
0 Can be equipped with 
either a data device (such as a 
personal computer equipped with a modem) or a 
loud ringing adapter (LRA) and an external signal- 
ling device (such as a loud bell, horn, flashing light, 
etc.) 
l Can be equipped with an SMDR Adapter and output 
device for generating various system reports 
l VOL UP and VOL DN keys allow the user to indi- 
vidually control speakerphone, handset, and ring 
tone volume levels (GLX-Plus Keysets only) 
l Self-test feature for testing keyset functions (GLX- 
Plus Keysets only) 
4.8 The DSS/BLF keys on the Executive and GLX- 
Plus Keysets provide one-key access to any station. The 
lamps under the DSS/BLF keys create the busy lamp 
field, which indicates the status of each keyset (idle, 
busy, call recalling from hold, forwarding calls, in 
do-not-disturb, in lock-out) by different flash rates. 
Integrated Speakerphone 
4.9 A built-in, integrated speakerphone is standard in 
all keysets. It allows users to place and receive outside 
calls and intercom calls without lifting the handset. 
Once a call is connected, the keyset user may speak 
handsfree over the speakerphone or lift the handset to 
speak privately. When using the handset, the user may 
switch to the speakerphone by pressing the ON/OFF key 
and replacing the handset. If enabled, pages and/or 
background music may be broadcast over the speaker 
when the phone is not being used. 
Optional Liquid Crystal Display (LCD) 
4.10 
Each GLX-Plus Display Keyset has a liquid crys- 
tal display (LCD) with one 16-character line. The dis- 
play helps the user to process calls more efficiently. 
There are display messages for date and time, numbers 
dialed, incoming calls, station and system status, system 
alarms, and programming. These displays are indicated 
throughout the FEAI’URES section of the manual. 
GLX-Plus Non-Display Keysets can be converted to 
display sets by installing an optional LCD Unit (Part  
						

							SPECIFICATIONS 
Issue 2. June 1993 INTER-TEL PRACTICES 
GLX-PLUS INSTALLATION & MAINTENANCE 
number 828.1188). Other keyset models cannot be 
equipped with displays. 
Optional Headsets 
4.11 A headset may be attached to any keyset by un- 
plugging the handset from the handset jack on the base 
of the keyset, plugging the headset into the handset jack, 
and entering a feature code to enable the headset. The 
ON/OFF key, which is used to turn the headset on and 
off, is lit when placing and receiving calls and unlit 
when the headset is not in use. The Standard and Execu- 
tive Keysets are compatible with industry-standard, 
four-conductor, modular headsets that have dynamic 
microphones, or carbon-microphorit headsets that are 
connected to the keyset through an externally powered 
jackset (which makes the headset dynamic-compat- 
ible). The GLX-Plus Keyset is compatible with indus- 
try-standard, four-conductor, modular headsets that 
have electret microphones. Refer to page 3-25 for in- 
stallation instructions. 
Optional Handset Amplifiers 
4.12 Although all keyseta are equipped with hearing 
aid-compatible (HAC) handsets, hard-of-hearing users 
may wish to have an adjustable amplifier installed. An 
amplifier may also be useful when the keyset is located 
in a noisy areas where users need to increase the receiver 
volume. The typical handset amplifier is an external de- 
vice that plugs into the keyset (where the handset is nor- 
mally connected); the handset is then plugged into the 
amplifier. Receiver voice volume is controlled by tum- 
ing a thumbwheel (or similar control) located on the am- 
plifier. Such amplifiers are generally equipped with a 
transformer that requires a 11OVAC outlet. Refer to page 
3-25 for installation instructions. 
NOTE: Due to its unique volume control circuitry, the 
GLX-Plus Keyset does not require a handset amplifier. 
4.13 Inter-Tel recommends the Walker Universal Am- 
plified Handsets (standard model W6-UNI-K or noise- 
cancelling model W6-UNI-K-NC). These amplifiers, 
which are compatible with carbon, dynamic, and elec- 
tret microphones, are available from: Walker Bquip- 
ment Corporation, PO. Box M, Highway 151 South, 
Ringgold, Georgia 30736, (800) 426-3738 or (404) 
9352600. When ordering, specify the color: ivory, 
black, or pearl. 
Optional Data Device or LRA for Executive and 
GLX-Plus Keysets 
4.14 The Executive Keyset has a four-conductormod- 
ular jack that can be used to connect eirhr a data device 
(such as a personal computer equipped with a modem) 
or a loud ringing adapter (LRA) and an external signal- ing device (such as a loud bell, horn, flashing light, etc.) 
to the keyset. 
4.15 GLX-Plus keyseta may be equipped with option- 
al Data Port Modules (part number 828.1094). The mod- 
ule contains a four-conductor, RI11 modular jack that 
can be used to connect either a data device (such as a 
personal computer equipped with a modem) or a loud 
ringing adapter (LRA) and an external signaling device 
(such as a loud bell, horn, flashing light, etc.) to the key- 
set. The Data Port Module is a source for 20-26mA of 
loop current. Refer to page 3-27 for instructions on in- 
stalling the optional Data Port Module. 
4.16 Specifications for modem-equipped data de- 
vice: The data device must have a direct-connection 
modem. The modem must be externally powered (or ca- 
pable of operating on 20mA of loop current) and have an 
RI11 CO interface. 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. 
Refer to pages 3-27 and 4-10 for installation and opera- 
tion instructions. 
4.17 Specifications for loud ringing adapter 
(IRA): An external LRA may be connected to provide a 
relay for controlling external signaling devices. The 
LRAis connected to the keyset (or its attached Data Port 
Module), and the external signaling device is connected 
to the LRA. Refer to page 3-29 for installation instruc- 
tions. Each time the keyset rings, the keyset (or Data 
Port Module) provides 20-26mA of loop current to the 
LRA. This causes the LRA contacts to close and acti- 
vates the signaling device. The LRA is not affected by 
the ring tone or the ringer volume of the keyset. 
4.18 The LRA device must meet the following char- 
acteristics. 
0 Relay coil nominal draw of 20mA 
0 Relay coil resistance of 100-400 ohms 
0 Minimum voltage of 17VDC 
0 Maximum voltage of 36VDC 
0 Contact rating of 120VRMS minimum 
4.19 Some types of signalling devices generate a cur- 
rent/voltage rating that could damage the LRA. The fol- 
lowing Wheelock products have been found to work 
properly with the GLX-Plus System. 
l Wheelock DCI-24-24 is an adapter that is used with 
Wheelock signaling devices. 
l Wheelock CRT-D-37 is a dry contact relay that is 
used with other manufacturer’s signaling devices. 
4.20 The LRA output of the Data Port Module is con- 
nected to the dry contact input on the Wheelock unit. 
Wheelock products can be ordered from a local supply

house, or call Wheelock directly at (201) 222-6880. In- 
stallation and operation instructions are included with 
each device. 
Optional GLX-Plus Keyset Battery Rack-Up 
4.21 Each GLX-Plus Keyset is equipped with its own 
internal clock. On display keysets, the clock can be set 
to show the current date and time (see page 4-34 for 
more information). If the keyset is unplugged or loses 
power, the date and time display defaults to 
“00 : 00 
MON JAN 0 1” and must be reprogrammed. 
4.22 In addition, each GLX-Plus Keyset also has VOL 
UP and VOL DN keys that allow the user to individually 
control and save speakerphone, handset, and ring tone 
volume levels. If the keyset is unplugged or loses power, 
the all saved volume levels return to the default settings. 
4.23 To preserve the date and time display and the vol- 
ume control settings during a power interruption, each GLX-Plus keyset may be equipped with optional battery 
back-up using a battery connection kit (828.1239) and a 
customer-provided 9V battery. The battery, when fresh, 
should save the date, time, and volume settings for 
approximately seven hours of accumulated down time. 
(See page 3-30 for battery installation instructions.) 
C. SINGLE-LINE SETS 
4.24 Up to two industry-standard, AC-ringing, single- 
line DTMF sets may be installed on a GLX-Plus System 
that is equipped with an optional APM. 
NOTE: The APM is supported only on KSUs equipped 
with the current 827.4012 software. 
4.25 Single-line set users access some station features 
simply by lifting the handset and entering a feature 
code. Other features are accessed using a combination 
of a hookflash and a feature code. Refer to the FEA- 
TURES section of this manual for details.

5. OPTIONAL SYSTEM EQUIPMENT 
A. SYSTEM BAlTERY BACK-UP 
5.1 To provide back-up power in the event of an AC 
power failure or brownout condition, the GLX-Plus Sys- 
tem power supply can have optional battery back-up 
using a customer-provided uninterruptable power sup- 
ply (UPS) unit or a standby power supply (SPS) unit. 
5.2 The UPS or SPS unit, which is connected between 
the AC outlet and the KSU’s AC power cord, must have 
the following characteristics: 
Sine wave output 
Transfer time of less than 25 milliseconds (a unit 
with a slower switching time may result in calls be- 
ing dropped when back-up power is switched on) 
Output rating of 50 Watts 
Low voltage cutoff circuit of 1OSVAC (minimum) 
Batteries can be internal or external 
NOTE: Even if the power supply unit has the specifica- 
tions listed above, it cannot be guaranteed that it will 
work properly with the Inter-Tel GLX-Plus System. 
Contact Customer Support for a listing of approved 
UPS/SPS power supplies and installation instructions. 
B. REPEATER APPLICATION FOR 
AMPLIFIED CO LINES 
5.3 Under most circumstances, the voice volume lev- 
els on outside calls are quite acceptable. However, dur- 
ing conferences involving multiple outside parties, 
some reduction in voice volume may be noticed because 
the GLX-Plus System is a passive design system and 
does not amplify conferencing. To increase the voice 
volume levels, Inter-Tel recommends the use of one of 
the following “repeater” products: the Tellabs 7201 
2-Wire Switched Gain Repeater or the R-TEC UMlOOO 
L3 Switched Gain Repeater. Both products provide 
from O-15 decibels of voice volume gain and allow 
regulation of the gain in each direction when simultane- 
ous voice transmission occurs. The switching sensitivity 
on both units is adjustable. For more information, refer 
to the manufacturer’s specifications provided with each 
product. 
NOTE: Installing the repeater product on a CO line will 
increase the voice volume levels of all calls using that 
line. For this reason, it may be desirable to install the 
product on one CO line and then use that line mainly for 
establishing outside conferences. 
5.4 Both products are installed at the MDF between 
the telephone company RJ14 jacks or RJ21X block and 
the KSU. When ordering a repeater unit, consult with 
the supplier for ordering the proper mounting shelf and power supply for the unit. The table below outlines the 
connections necessary for proper installation with the 
GLX-Plus System.

5.5 Additional information on operating and adjusting 
the repeater unit is included with the product. 
C. DOORBOX 
5.6 For a doorbox application, Inter-Tel recommends 
the Valcom V-2901 Universal Door Answering Unit. 
This unit, along with the Valcom V-1070A Door Plate 
Speaker, is hooked up to a CO circuit on the GLX-Plus 
System. When a person presses a button on the door 
plate speaker, the unit generates ringing on the CO line. 
By answering the ringing line, a system user can talk 
with the person at the door. If the door is equipped with 
an electric strike plate, the system user may allow access 
by dialing a code or pressing an external button. To call 
the Valcom doorbox, the system user goes off hook and 
presses the line key assigned to the unit (or dials the 
appropriate CO line access code). 
5.7 In database programming, make sure that the de- 
sired keyseta have access to the CO line assigned to the 
Valcom unit. Also, assign CO line ring-in to the 
keyset that will be answering calls from the Valcom 
unit. 
5.8 The Valcom door answering unit and talkback 
speaker can be ordered from a local supply house. In- 
stallation and operation instructions are included with 
the unit. 
D. ANSWERING MACHINE OR VOICE MAIL 
5.9 If desired, an optional answering machine or voice 
mail unit can be connected to an available single-line 
circuit on the GLX-Plus APM. Depending on the spe- 
cific capabilities of the unit, calls can easily be placed, 
transferred, or forwarded to the answering machine or 
voice mail unit. 
5.10 For additional information and for specific voice 
mail unit recommendations, contact Customer Support. 
NOTE: The GLX-Plus System does not have loop cur- 
rent detection capabilities. Therefore, disconnect super- 
vision or any drop in loop current will not cause the 
GLX-Plus to drop the CO line connection. If an answer-  
						

							INTER-TEL PRACTICES 
GLX-PLUS INSTALLATION & MAINTENANCE SPECIFICATIONS 
Issue 2, June 1993 
ing machine is connected to the APM, it may be neces- 
sary to set a maximum record time. 
E. FAXMACEKINE 
5.11 A facsimile (FAX) machine allows the transmis- 
sion of a picture, drawing, or document over a standard 
phone line to be reproduced by another machine at the 
receiving end. This can be an efficient, cost-effective 
communication tool. 
5.12 Standard installation procedures for FAX ma- 
chines involve connecting the machine to a dedicated 
line for sending and receiving documents. With a GLX- 
Plus System, the FAX facilities-are integrated with the 
telephone system. Some of the special capabilities that a 
GLX-Plus System can add to a FAX installation include 
the following: 
Incoming FAX calls can be forwarded directly to a 
FAX machine and/or they can be answered by a sta- 
tion user and transferred to the FAX machine. This 
allows FAX calls to come in on any line; there is no 
need for a dedicated line. 
The optional SMDR feature can help track outgoing 
FAX calls for billing purposes. 
The GLX-Plus System is compatible with standard 
FAX machines; there are no special requirements. 
5.13 A FAX machine can be installed on any unused 
APM single-line circuit, and can be assigned outgoing lines. For more information, refer to pages 4-12 and 
5-14. 
F. STATION MESSAGE DETAIL 
RECORDING (SMDR) ADAPTER AND 
OUTPUT DEVICE 
5.14 If desired, an optional SMDRAdapter and output 
device (printer, terminal, etc.) can be connected to one 
Executive or one GLX-Plus Keyset. The device allows 
the programmer to print a variety of useful SMDR, pro- 
gramming, and system reports. 
NOTE: If used on an Executive Keyset, the SMDR 
Adapter is connected to the DATA jack on the back of 
the keyset. If used on a GLX-Plus Keyset, the SMDR 
Adapter is connected to the three-pin header labeled J8 
on the keyset’s control board. 
5.15 The SMDR Adapter (model no. GSA232) is 
available from Integrated Design Services (IDS), 5737 
W. Ivanhoe Street, Chandler AZ, 85226-1823, phone/ 
FAX (602) 961-4448. 
5.16 Since the SMDR reports are 80 characters wide, 
the output device connected to the SMDR Adapter must 
be able to print reports with a width of 80 characters. 
Also, the device must be placed within 50 feet (15 
meters) of the KSU. Additional information on instal- 
ling, programming, and operating the SMDR Adapter is 
included with the product.
