10. BATTERY BACK-UP EQUIPMENT 
10.1 The GLX-Plus System can be equipped with op- 
tional system battery back-up using an uninterruptable 
power supply or a standby power supply. (Refer to page 
2-12 for specifications.) 
10.2 To install an uninterruptable power supply (UPS) 
or standby power supply (SPS) unit, follow these steps: 
(1) Turn the KSU AC power switch (PWR) to the 
OFF position and unplug the AC power cord. 
(2) Plug the UPS/SPS unit into the KSU AC outlet. 
(3) Plug the surge/spike protector into the UPS/SPS 
unit. 
(4) Plug the KSU AC power cord into the surge/ 
spike protector. 
(5) Turn the KSU and UPS/SPS unit power switches 
to the ON positions. 
11. POST-INSTALLATION CHECKLIST 
11.1 To ensure that the system has been installed prop- 
erly, review the installation outline on page 3-2. Then 
review the items in the following list as a final check. 
- 
KSU location, station locations, and cable runs meet 
environmental requirements and cable lengths are 
within loop limits. - 
Bridging clips are installed where required on all 
MDF blocks. 
- 
Gas discharge tubes with silicon avalanche suppres- 
sors are installed on the CO lines for lightning pro- 
tection. Also, if extra protection is desired, the cable 
between the telephone company RJ-type block and 
the gas discharge tubes is at least 75 feet long. 
- 
The KSU is attached to an approved earth ground. 
- 
The system power supply is plugged into an isolated, 
dedicated AC outlet, and no other equipment has 
been plugged into the same outlet. An extension 
cord was not used. A voltage surge/spike protector is 
installed to reduce the effects of AC voltage surges 
and spikes that can cause system malfunctions, false 
logic, and/or damage to the electronic components. 
- 
Amphenol-type connectors, modular jack connec- 
tors, and station instrument line cords are all con- 
nected securely. All keyset and single-line stations 
are working properly. 
- 
All optional equipment is properly installed and 
working correctly (for example, radio is tuned to a 
station, etc). 
- 
CO dial tone is present and calls can be placed and 
received using all CO lines.

1. INTRODUCTION 
1.1 The GLX-Plus System has many easy-to-use 
features. This section describes the features and 
provides detailed instructions on their use. Refer to the 
user guides for simplified instructions on using station 
features. 
2. FEATURE KEYS AND CODES 
2.1 Keysets have feature keys that allow one-key 
access to the station features. 
2.2 At keyset stations, most of the station features are 
selected using the feature keys. Other features require 
the user to enter a feature code. The feature codes that 
are used at keyset stations to enable and disable station 
features include the following: 
0 Call Forward If No Answer/Busy . . . #Cl1 
l Call Forward Unconditional . . . . . . . #02 
0 Do-Not-Disturb . . . . . . . . . . . . . . . . . #03 
0 Headset . . . . . . . . . . . . . . . . . . . . . . . . ##04 
l Background Music . . . . . . . . . . . . . . . #06 
(Executive and GLX-Plus keysets have a feature key 
for background music.) 
2.3 There are three additional feature codes: 
l Executive and GLX-Plus keysets can use the Priva- 
cy Enable feature code (SPCL 8) 0 Executive keysets, and GLX-Plus keysets that are 
equipped with Data Port Modules, can use the Loud 
Ringing Adapter (LRA) feature code (#05) to enable 
and disable the LRA. 
0 GLX-Plus keysets can have customized date/time 
displays using the Date/Time Display feature code 
(SPCL 4) and a series of programming routines 
2.4 One station can be designated as the SMDR device 
station. That station uses special codes to generate 
SMDR reports and database programming reports. The 
SMDR station and its codes are explained on page 4-35. 
2.5 Single-line stations use the following feature 
codes:

3. CO LINE FEATURES 
3.1 This section explains the CO line functions and 
programmable features. 
NOTE REGARDING CO LINE SECURITY 
While this system is designed to be reasonably secure 
against CO line misuse by outside callers, there is no im- 
plied warranty that it is invulnerable to unauthorized in- 
trusions and toll fraud. If the central off& does not 
provide supervision, and disconnect the call when one 
party hangs up, it is possible for a caller to remain con- 
nected to a CO line circuit. If this hrppens, and the caller 
begins dialing, the call could be placed through the 
GLX-Plus System and would then be billed to the sys- 
tem’s owner. The system cannot check this type of call 
for toll restriction. This problem could arise when a call 
is connected to a station, when a call is in an unsuper- 
vised conference calls. 
The GLX-Plus System does not have loop current detec- 
tion capabilities. Therefore, disconnect supervision or 
any drop in loop current will not cause the GLX-Plus to 
drop the CO line connection. The GLX-Plus user must 
hang up when completing a call. If a call has been for- 
warded to the public network, the Forward To The Pub- 
lic Network timer will limit the duration of the call and 
disconnect the line when the timer expires. If an answer- 
ing machine is connected to an APM, it may be neces- 
sary to set a maximum record time. 
A. DUAL-TONE MULTI-FREQUENCY 
(DTMF’) OR DIAL-PULSE SIGNALING 
3.2 The system can be installed with either DTMF or 
dial-pulse lines. Dial-pulse lines must be specially des- 
ignated in database programming, because all lines are 
designated as DTMF when the system is initialized. 
3.3 When using dial-pulse signaling, DTMF tones are 
not transmitted over the CO line when the keypad keys 
are pressed. To use DTMF tones while on a dial-pulse 
line, the user can temporarily convert the keyset to 
DTMF signaling by pressing the asterisk (*) key at any 
time after the pulse-dialed digits have been sent over the 
CO line. (If the user switches to DTMF while the pulse- 
dialed digits are being sent, the system will wait until the 
last pulse-dialed digit has been sent before switching 
and sending the first DTMF digit.) This application is 
useful when the user must dial out on a dial-pulse line and then communicate with a computer or other device 
that recognizes DTMF tones. 
3.4 As the user dials a telephone number manually or 
uses speed dial or redial on a dial-pulse line, the system 
stores the digits in a buffer for conversion to dial-pulse 
signals. The user then hears the digits being sent out as 
the system dials the number. The speed at which the sys- 
tem sends the digits is determined by the Pulse-Dial 
Speed and Pulse-Dial Interdigit timers. These timers are 
programmable and can be adjusted to meet the speciti- 
cations of the central office. 
B. FLEXIBLE INCOMING RING 
ASSIGNMENT (ALTERNATE POINT 
ANSWERING) 
3.5 When the system is initialized, only the atten- 
dant’s station (intercom number 10) rings for incoming 
calls on the CO lines. However, the associated line key 
flashes on all keysets and any keyset user may answer an 
incoming call by pressing flashing line key. Single-line 
set users can use the call pick-up (reverse transfer) fea- 
ture to pick up ringing calls (see page 4-24). Using sta- 
tion feature programming, CO lines can be programmed 
to ring in on any or all stations. CO lines can ring in at 
any station, without ringing in at the attendant’s station. 
C. FLEXIBLE NIGHT RINGING 
ARRANGEMENT (NIGHT RING MODE) 
3.6 CO lines that ring in at the attendant’s station can 
be programmed to ring in at one or more alternate sta- 
tions when the system is placed in night ring mode. Re- 
fer to page 5-12 in PROGRAMMING for more 
information. CO lines that are not programmed to ring in 
at the attendant’s station are not affected by night ring 
mode and continue to ring in as programmed. Attendant 
recalls continue to ring at the attendant’s station when 
the system is in night ring mode. 
D. CO LINE RESTRICTION AND STATION 
TOLL R.ESTRICTION 
3.7 As a means of restricting outgoing calls, stations 
can be prevented from having access to one or more CO 
lines for placing calls. This is performed during station 
feature programming. Users attempting to place a call 
using a restricted CO line hear a busy signal; however, 
they can answer incoming calls, calls on system hold, or 
recalls on the restricted CO lines. 
Page 4-4

GLX-PLUS INSTALLATION & MAINTENANCE FEATURES 
Issue 2, June 1993 
3.8 As a means of controlling costs, the system can be 
programmed to restrict specific stations from being used 
to dial toll calls. The toll restrictions and exceptions in- 
clude: 
0 Basic Toll Restrictions 
l Allow System Speed-Dial Numbers to Bypass Toll 
Restriction 
0 Exclude CO Line(s) from Toll Restriction 
Basic Toll Restrictions 
3.9 There are three system programming options 
available that are used with station option 6 (toll restrict) 
to cause the system to analyze and/or count the digits 
dialed at the station. 
System option 1 prevents a station user from placing 
a call when the number dialed has “0” or “1” as the 
first digit. If the first digit is a “0” or “l”, the call is 
dropped immediately. System option 1 is enabled 
during initialization. System speed-dial numbers are 
not toll restricted when system option 4 is enabled. 
System option 2 prevents a station user from placing 
a call when the number dialed begins with a “0” or 
“l”, or when the number exceeds eight digits. If the 
first digit is a “0” or a “l”, the call is dropped im- 
mediately; if the call exceeds eight digits, it is 
dropped when the ninth digit is dialed. The eight- 
digit limit is in effect throughout the call. If a ninth 
digit is dialed while the call is in progress, the call is 
dropped. System speed-dial numbers are not toll re- 
stricted when system option 4 is enabled. 
System option 3 is identical to option 2 except that a 
station user may dial directory assistance (1411, 
1-555-xXxX, xXx-555-xXxX, or l-XXX- 
555-XXXX), emergency (1911), and toll-free (l- 
800-XXX-xXxX or 800-XXX-xXxX) numbers. 
3.10 If more than one of the above options are en- 
abled, the system only checks the lowest-numbered op- 
tion. If a restriction is found, the call is dropped even if 
there are other options remaining. Selecting no options 
during programming disables the toll restriction feature. 
Allow System Speed-Dial Numbers to Bypass Toll 
Restriction 
3.11 System option 4 permits system speed-dial num- 
. 
bers to bypass the toll restrictions enabled by option 1,2, 
or 3. (However, any digits dialed after the speed-dialed 
number ore checked for toll restriction.) Because this 
option is an exception to the other options, it is never 
used by itself. Exclude CO Line(s) from Toll Restriction 
3.12 The system can be programmed to allow access 
to one or more CO lines for placing calls that would 
otherwise be denied by system option 1,2, or 3. The un- 
restricted CO line can be a local line, WATS line, PX 
line, PBX line, etc. 
4. PROTECTION AGAINST POWER 
FAILURE 
A. DATABASE BATTERY BACK-UP 
4.1 The Main Control PCB contains a lithium battery 
that protects the programmed database, system and sta- 
tion speed-dial numbers, redial memory, and call for- 
ward requests in the event of a power failure. Headsets, 
do-not-disturb, background music, and the data device 
interface are returned to default status (disabled) if a 
power failure occurs. The battery can protect the data- 
base for 10 years ofnormal system operation, or until the 
accumulated system downtime exceeds one year. 
B. POWER FAILURE BACK-UP 
4.2 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 us- 
ing a customer-provided uninterruptable Power supply 
(UPS) unit or a standby power supply (SPS) unit. Refer 
to page 2-12 for details. 
C. GLX-PLUS KEYSET BATI-ERY BACK-UP 
4.3 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. If the keyset is un- 
plugged or loses power, the date and time display 
defaults to “OO:OO MON JAN 01” and must be repro- 
grammed. 
4.4 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. 
4.5 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 bat- 
tery back-up using a battery connection kit (828.1239) 
and a customer-provided 9V battery. Refer to page 3-30 
for installation instructions.

5. STATION INSTRUMENTS 
5.1 To allow system flexibility and cost efficiency, a 
variety 
of station instruments can be used on the GLX- 
Plus System. They are: 
l Standard Keyseta 
l Executive Keysets 
l GLX-Plus Keysets - display and non-display 
l Industry-standard, AC-ringing, single-line, dual- 
tone multi-frequency (DTMF) sets 
A. KEYSETS 
5.2 The Executive and GLX-Plus keysets differ from 
the Standard Keyset in that they have additional feature 
keys and Direct Station Selection/Busy Lamp Field 
(DSS/BLF) keys. E xecutive keysets have a jack for con- 
necting a data device or loud ringing adapter; GLX-Plus 
keyset can be equipped with an optional Data Port Mod- 
ule for that purpose. GLX-Plus Display Keysets also can 
have an optional one-line, 16-character liquid crystal 
display. 
5.3 The GLX-Plus keyset is a special type of keyset 
that contains an audio-integrated module which allows 
the user to adjust volume levels independently for 
pages, calls, ring tones, etc. Throughout the manual, 
whenever the word “keyset” is used, it includes GLX- 
Plus keysets (unless stated otherwise). 
Handsfree Speakerphone 
5.4 Every keyset has an integrated speakerphone that 
allows handsfree operation on outside calls and hands- 
free answering of intercom calls. The speakerphone is 
automatically activated by incoming intercom calls or 
when a line key is pressed while the keyset is on hook. 
The ON/OFF key is used to transfer the voice path be- 
tween the handset and the speakerphone and to hang up 
from handsfree calls. 
5.5 There are two keyset programming options that 
can affect the speakerphone. Keyset option 2 disables 
the handsfree feature on incoming intercom calls. Key- 
set option 4 disables the feature that automatically acti- 
vates the speakerphone when a line key is pressed. With 
either option enabled, the ON/OFFkey is used to control 
the speakerphone. 
5.6 All keyset stations allow the user to dial while on 
hook. In addition, the keyset speaker may provide back- 
ground music (if an external music source is installed) 
and is used to receive pages. Line Keys 
5.7 The six CO line keys provide direct access to the 
CO lines. Each line key is equipped with an LED that 
indicates the status of the CO line (in use, holding, recal- 
ling, etc.). 
Feature Keys 
5.8 The keys found on all keysets are described below:

Direct Station Selection/Busy Lamp Field 
(DWBLF) Keys 
5.11 The Executive and GLX-Plus keysets have 12 
DSS/BLF keys that provide one-key intercom access to 
each of the 12 stations. The LEDs under the DSS/BLF 
keys create a busy lamp field and flash at different rates 
to indicate the status of each station. Each flash rate has 
a distinct meaning, as described below. Flash rates are 
given in interruptions per minute (IPM) or seconds on/ 
Off. 
FLASH RATE INDICATION 
STEADY The station is busy. 
(constantly lit) 
LOCK-OUT The station is in lock-out (off hook 
FLASH with no activity) or unplugged. 
(0.5 sec. on/ When a station is causing lockout 
3.5 sec. off) flash, press the associated DSS/ 
BLF key on any Executive or 
GLX-Plus keyset. Canceling DSS/ 
BLF lockout flash on one keyset 
cancels the DSS/BLF flash on all 
Executive and GLX-Plus keysets. 
Also, placing the handset on hook 
at the locked-out station will cancel 
the flash.

(60 IPM) The station is in call forward mode. 
Automatic Line/Intercom Call Access 
5.12 This keyset option (Programmed through the 
keyset features program) allows the user to answer any 
outside or intercom call that is ringing in to the station by 
simply lifting the handset. Intercom calls that would 
normally be received handsGee still automatically acti- 
vate the speakerphone, even if the keyset is ringing. 
NOTE: Initializing the database disables this feature. 
5.13 If more than one call is ringing at a time, they are 
picked up in the following order: 
l Private intercom calls 
0 Direct ring-in 
Page 4-8 
l Transferred calls 
0 Recalls 
0 Busy line callbacks (queues) 
5.14 If more than one call of the same type is ringing, 
the lowest-numbered line is chosen first. 
5.15 Camped-on calls cannot be answered by simply 
lifting the handset or pressing the ON/OFF key. 
Selectable Ring Tone (GLX-Plus and upgraded 
Executive and Standard keysets only) 
NOTE: If the ring pitch does not change when using this 
procedure on an Executive or Standard keyset, it is an 
older version keyset that has not been upgraded and does 
not support this feature. 
5.16 The pitch of ring signals can be changed on key- 
sets to create distinctive ringing. If stations are placed 
close together, changing the pitch makes each station’s 
ring easier to recognize. The ring pitch is changed by 
pressing keys on the keypad. 
5.17 When the system is initialized, all keysets are set 
to the highest frequency (8OOHz). 
5.18 
TO CHANGE RING PlTCHATANE.YECUm!E OR GLX- 
PLUS KFYSET SiXlTON: 
NOTE: The KSU PRG EN switch must be in the OFF 
position. 
(1) 
(2) While on hook, dial #07. 
Dial the two-digit code (00-15) for the desired 
ring pitch. The display shows RING TONE: XX. 
The keyset will ring at the selected pitch for 1.5 
seconds to confirm the entry. 
NOTE: On GLX-Plus keysets, ring tone selec- 
tion 15 is for silence. You will not hear a ring 
tone, but you will receive the confirmation tone 
after performing step 4. When the station re-
