1. INTRODUCTION 
1.1 Inter-Tel’s GMX-48 System is a unique elec- 
tronic key telephone system that is designed to meet 
the needs of growing businesses. The compact, modu- 
lar design makes the system easy to install, service, 
and expand. The programmable features provide 
over 120 user-friendly applications to meet each cus- 
tomer’s needs. 
.: 
1.2 The main processing unit of the GMX-48 Sys- 
tem, called the KSU Control Board (KCB), is used to 
install C.O. lines, keysets, and DSS/BLF Units. For 
increased capacity, as inany as five modules can be 
attached to the KCB. All five can be Expansion Mod- 
ules (EXPs) for installing additional C.O. lines, key- 
sets, and DSS/BLF Units. Or, up to two of the five 
can be Accessory Port Modules (APMs) for installing 
single-line devices (such as single-line sets, playback 
devices, voice mail units, facsimile machines, etc.). 
For a drawing showing some of the equipment that 
can be connected to the system, see Figure 2-l on 
page 2-20 in SPECIFICATIONS. 
1.3 The maximum number of stations and C.O. 
lines available depends on the number and type of 
modules installed. For complete information on sys- 
tem capacities and a system configuration chart, refer 
to page 2-2 in SPECIFICATIONS. 
1.4 Highlights of the GMX-48 System’s design in- 
clude: 
Advanced microprocessor technology. 
Flexible programming to customize many system 
and station features. 
Modular, easily replaceable hardware with add-on 
capabilities for optional features. 
Capacity for 
up to: 
NOTE: In many circumstances, the following 
maximum capacities will never be reached be- 
cause there will be a combination of modules in- 
stalled. 
- 24 Central Office (C.O.) Lines (Loop start 
lines installed in increments of four, depend- 
ing on the number of EXPs installed.) 
- 48 Stations (Combinations of keysets, DSS/ 
BLF Units, and single-line devices in six- or 
eight-station increments, depending on the 
number of EXPs and APMs installed. EXPs 
can have up to eight keysets and DSYBLF 
Units connected, while APMs can have up to 
six single-line devices connected. Keysets can 
be any combination of 24-line standard key- 
sets, 24-line display keysets, and 1Zline [non- 
display] keysets.)

INTER-TEL PRACTICES 
GMX-48 INSTALLATION & MAINTENANCE 
NOTE: 
At least one 24-line display keyset 
should be installed to program selected system 
data, receive system alarm messages, act as the 
attendant for unsupervised C.O. recalls, etc. 
- 5 Direct Station Selection/Busy Lamp Field 
(DSS/BLF) Units (Keysets and DSS/BLF 
Units use separate keyset circuits. For each 
DSWBLF Unit installed, one less keyset may 
be installed. 
If desired, all five DSS/BLF Units 
may be connected to the KCB or the same 
EXI?) 
1.5 The GMX-48 System is available in three soft- 
ware “packages” - one KF-rated and two MF-rated. 
The KF-rated system permits only one line to be 
accessed per line key, and there can be only one auto 
line and only one line in each of the line groups. The 
MF-rated systems permits one-key access to multiple 
outgoing lines. The three software packages are listed 
below. 
0 KF-rated Basic package (part no. 827.6007): 
- The Basic software package has all of the fea- 
tures described in this manual 
except single- 
line device capability (APMs cannot be used), 
direct inward system access (DISA), auto- 
mated attendant, intercom/C.O. directory, au- 
tomatic route selection (ARS), system activity 
report (SAR), and voice mail/computer hunt 
groups. 
l MF-rated Intermediate package (part no. 
827.6006): 
- The 
Intermediate software package has all of 
the features described in this manual 
except 
playback device capability, direct inward sys- 
tem access (DISA), automated attendant, au- 
tomatic route selection (ARS), system activity 
report (SAR), and voice mail/computer hunt 
groups. 
l MF-rated Advanced package (part no. 827.6005): 
- The Advanced 
software package has all of the 
features described in this manual. 
2. HARDWARE SUMMARY 
2.1 The SPECIFICATIONS section of this manual 
explains environmental requirements of the system, 
describes the hardware, and gives pre-installation in- 
formation. The hardware descriptions include: Key 
Service Unit (KSU), power supply, station instru- 
ments, and additional equipment needed for the op- 
tional features. 
3. 
INSTALLATION AND 
MAINTENANCE SUMMARY 
3.1 The modular design and self-diagnostic capabil- 
ities of the system facilitate installation and repair 
with minimal down-time. Strict quality control stan- 
dards for manufacturing and thorough field testing 
provide the system with the reliability demanded by 
today’s high-technology market. 
3.2 The INSTALLATION section contains instruc- 
tions for assembling the main distribution -frame 
(MDF) and for installing the KSU Control Board 
(KCB), power supply, Expansion Modules (EXPs), 
Accessory Port Modules (APMs), station instru- 
ments, and optional hardware. 
3.3 After the system is installed, the flexible soft- 
ware allows the database to be customized to meet 
the customer’s needs. A programming terminal is 
used to perform this task. The PROGRAMMING 
section describes the procedures for initializing and 
programming the system features. 
3.4 The TROUBLESHOOTING section gives in- 
structions for correcting system problems and replac- 
ing defective parts. A list of part numbers and a 
recommended inventory of spare parts are located in 
the REPLACEMENT PARTS section.
