semblies at the station locations.
Mount the MDF backboard and assemble the ter-
minal blocks on the backboard. If any 
Tl spans
are to be installed, terminate them on eight-con-
ductor modular jack assemblies at the MDF.NOTE: The 
Tl span is typically connected to
the standard 
R&X.! modular jack provided on
the Tl Card. However, in certain situations (e.g.,when using an external CSU equipped with a
DB15 connector), it may be more convenient to
use the card’s optional DB15 connector instead.

PRE-INSTALLATION CHECKLIST
3.1To make installation easier, use the checklist on
the following pages when preparing to install the sys-tem. (Hardware specifications are included in the
SPEClFICAI’IONS section.)
A. ESX4BLISHSIlI’k3LE
EI’MRONMENTAL CONDITIONS FORTHE SYSTEM
- Locate the equipment cabinet within 5 feet (1.5 me-ters) of an isolated, dedicated, 
105-125VAC,
57-63H2, 15A, single-phase commercial power
source.
NOTE: This 
musf be an isolated, dedicated AC cir-
cuit for proper operation. All three wires (power,
neutral, and ground) must be run separately 
from the
outlet to the breaker panel without being bonded to
any other wire or circuit. DO 
NOT plug any other
equipment into this outlet. To maintain the protec-
tion provided by the isolated, dedicated circuit, the
length of the AC power cord limits the distance be-
tween the power supply and the outlet; DO 
NOTuse
an extension cord. Also, to protect the system fromAC voltage surges, a surge/spike protector is
supplied with the system (refer to page 2-9 for speci-
fications).
From UL 1459, apnxakct safety specification govttming
telephone equipment:
- Never install telephone wiring during a lightning
storm.
Page 3-3
- Select the equipment cabinet location to minimize
cable run length. Station instruments connected tothe system must not exceed the limits (using
24AWG wire) listed in the table on page 3-29. The
ohm values are loop measurements; feet 
(meter)val-
ues are the maximum one-way measurements from
the equipment cabinet.
- Never install telephone jacks in wet locations unless
the jack is specifically designed for wet locations.
- Never touch uninsulated telephone wires or termi-
nals unless the telephone line has been disconnected
at the network interface.
- Use caution when installing or modifying telephonelines.
- Do not expose the equipment cabinet location to di-rect sunlight, high humidity, heat, dust, or strong
magnetic fields (such as those generated by heavy
motors and large copy machines).
B.ASSEMBLE THE NECESSARY TOOLS
AND SUPPLIES
- The MDF requires a 4 x 8-foot (1.2 x 2.4meter),
x-inch plywood backboard. This should provide
sufficient room for all blocks and peripheral equip
ment.
- Industry-standard,
three-pair(six-conductor)twisted cable to run 
from the MDF to all station
instruments, including: 
keysets, analog DSS/BLF
Units, Attendant Computer Consoles, 
ESLSs, SLIs,
single-line 
DTMF sets, and playback devices. (For
exceptions, see the NOTE on page 3-6.)
- For cooling purposes, provide ample air space
around the equipment cabinet assembly (minimum
one foot on all sides). Other than the programming
PC, do not place or store items on top of the equip
ment cabinet.
- Six-conductor modular jack assemblies for all sta-
tion instruments. (For exceptions, see the NOTE on
page 3-6.)
- The SMDR/SMDA output device(s) must not have
cables longer than 50 feet (15 meters).
- A high-impedance digital multimeter to check the
power supply and ensure correct wiring of the modu-
lar jack assemblies. Multimeter accuracy must be
H.5% or better.
- Locate the equipment in a climate-controlled room
with the following environmental conditions:- Standard terminal blocks (66Ml-50 type) and bridg-
ing clips for constructing the MDF.

NOTE: It is recommended that the maximum oper-
ating temperature (as stated above) 
never be exceed-ed. Therefore, when installing the equipment
cabinet and station instruments, allow a sufficient
margin for error in case of air conditioning failure,
routine maintenance, plant shutdown, etc. 
As a gen-
eral rule, if conditions are suitable for office person-nel, they are also suitable for all equipment and
station instrument operation. A properly controlled
environment will help to extend the operating life of
the equipment.

Ifauy ‘II spans are to be installed: Depending on
the type of 
Tl terminationused by the telephone compa-
ny (telco) and how close it is to the MDF, the following
tools and supplies are also needed.
NOTE: The 
Tl span is typically connected to the stan-dard 
RJ48C modular jack provided on the Tl Card.
However, in certain situations (e.g., when using an ex-
ternal CSU equipped with a DB15 connector), it may be
more convenient to use the card’s optional DB15 con-
nector instead. Refer to page 3-20 for more information.For Tl spans terminated on 
RJ4SC jacks near the
MDF:
- Four-pair, non-reversing, mod-to-mod line cords
(one for each Tl span installed).For Tl spans terminated on 
RJ48C jacks away fromthe MDF (see 
Figure 3-9 on page 3-18):
- Eight-conductor modular jack assemblies (two for
each 
Tl span installed).
- Four-pair, non-reversing, mod-to-mod line cords
(two for each Tl span installed).
- Tl cable -enough to extend from each telco RJ48C
jack to the MDF (see page 
2-20 for cable specifica-
tions).For Tl spans terminated on an 
RI-type block (see
Figure 3-11 on page 3-19):
- Eight-conductor modular jack assemblies (one for
each 
Tl span installed).
- Four-pair, non-reversing, mod-to-mod line cords
(one for each Tl span installed).

nation to the MDF (see page 
2-u) for cable specifi-
cations).C.
PLAN STATION LOCATIONS AND TYPES
OF STATION INSTRUMENTSNOTE: For information on the GX and GMX station
instruments, refer to appendixes A and B in the back of
this manual.
- Prepare a cable identification plan using station cir-cuit numbers; do not use extension numbers (see
page 3-6 for details).
- Keysets: The IMX 256 System has the capacity for
up to 256 
keysets if using the new digital keysets or
8-line IMX AIM keysets, which can be installed two
to a circuit. The GMX-256 System has the capacity
for up to 128 
keysets. Refer to SPECIFICAI’IONS,
starting on page 2-21, for a listing of the available
keyset models and for more information on maxi-
mum station capacities. Excluding nondisplay only
models, all standard 
keysets can be converted to dis-play 
keysets by installing optional Liquid Crystal
Display (LCD) Units (see REPLACEMENTPARTS
for part number).
NOTE: The equipment cabinet has 16 slots for sta-
tion and trunk cards. 
The acmal number of stations
and 
trunks available depena3 on the number and
type of 
cam& station hsmmentts,and power supply
modides installed
- DSWBLF Units: Up to 50 keyset circuits can be
equipped with 
DSS/BLF Units. Digital units are
powered by their own AC transformers and do not
require a 
DKSC circuit that is separate from the key-
set’s circuit. Each analog unit requires one 
KSC or
KSC-D circuit and its own cabling. As many as four
analog units can be installed on a single 
XSC.
- Attendant Computer Consoles: If desired, up to
128 Attendant Computer Consoles can be installed
on the system. The consoles are connected to KSC or
KSC-D circuits.

S’IXI’ION CABLING
4.1Floor plans should be developed to aid in proper
station cabling in a star (home run) configuration from
the equipment cabinet. The cables are run from the sta-
tion locations to the station blocks at the MDF. Refer to
page 2-4 for cabling requirements.
4.2Both ends of each cable should be labeled with the
station’s circuit 
number (hardware address). The circuitnumber 
(X.Y) designates the card’s position in the
equipment cabinet (X = 1-16) and the circuit positionon
the card 
(Y = 1-16 for DKSCS, Y = l-8 for KSCs, KSC-
lh, and IDES, Y = 1-16 for SLCs). For example, circuitnumber 4.6 identifies the sixth circuit on the card in-
stalled in slot number four.NOTE: When IMX 
8-line dual-circuit keysets are in-
stalled two to a circuit, the circuit number is separated
into two parts (A and B) in database programming (e.g.,
circuit 
4.6A and 4.6B).43
When the system is first powered up, the default
configuration is used to assign extensionnumbers to the
station circuits. 
On IMX 256 Systems, card slots l-4 are
considered 
KSCs or RSC-Ds, slots 5-6 are DKSCs, slots7-8 are unassigned, slots 9-12 are 
SLCs, and slots
13-16 are LGCs. On GMX-256 Systems, card slots l-8
are considered 
KSCs or KSC-Ds, slots 9-12 are SLCs,
and slots 13-16 are 
LGCs. Changes to the default con-
figuration can be made through database programming.
Refer toPROGRAMMING,page 5-170, for more in-
formation.
4.4The system assigns extension number 100 to sta-
tion circuit 1.1, extension number 101 to station circuit
1.2, and so on to match the initial configuration. Circuit
1.1 is equipped as the primary attendant’s 
keyset when
the system is in the default 
configuration. Through data-
base programming the circuits can be assigned differ-
ent extension numbers and/or be changed to four-digit
extension numbers. Refer to 
PROGRAMMING, page
5-58, for more information.
NOTE: “B” circuit 
8-line IMXAlh4 keysets do not have
extension 
numbers until assigned one in database pro-
gramminp.
4.5Each analog 
DSS/BLF Unit requires a KSC or
RX-D circuit and cabling that is separate from the key-
set’s circuit and cabling. If50 
keyset circuits are used for
analog 
DSS/BLF Units, 50 fewer analog keysets and/orAttendant Computer Consoles can be installed. Up to
four units can be installed on a single Reyset Card.A. 
RUNNINGCABLE
NOTE: It is recommended that three-pair twisted cable
and six-conductor modular jacks be used for all station
connections. This allows the various types of station in-
struments to be easily interchanged, if necessary. How-ever, digital 
keysets, ESLSs, SLIs, single-line IYIMF
sets, and playback devices can be installed using 
one-
pair twisted cable and four-conductor modular jacks. (Ifthree-pair cable is used for wiring digital 
keysets,
single-line sets, and playback devices as recommended,
extra terminal blocks and the use of 
crossconnect wir-
ing techniques are required.)4.6 From the MDF location, run industry standard,
three-pair (six-conductor) twisted (24AWG, level-l or
better) cable to 
keysets, analog DSS/BLF Units, Atten-
dant Computer Consoles, single-line sets, and playback
devices. Follow these guidelines:
Install proper type cable for the application accord-
ing to the National Electrical Code and local build-ing 
txnks.
Avoid cable runs parallel to fluorescent light fixtures
or AC lines not in conduit. If these obstacles are un-
avoidable, run the cables across them at right angles.
Do not run station cables inside electrical conduit al-
ready occupied by AC power cable. (To do so is a
violation of the National Electrical Code.)
Do not run cables near equipment with electric mo-
tors or through strong magnetic fields, such as thosegenerated by large copy machines, arc welding
equipment, heavy motors, etc.Do not place station cables where they can be
stepped on or where they can be rolled over by office
furniture.
Ifusingmulti-pair (e.g., 
25-pair) cablerunstomulti-ple station locations, do not include AC-ringing
single-line sets, AC-ringing auxiliary equipment, or
trunks in a cable being used for analog 
keysets, At-tendant Computer Consoles, or analog 
DSS/BLF
Units. Stations using analog 
keyset circuits should
be routed in separate multi-pair cable runs.
Do not exceed the loop limit measurements (using
24AWG wire) for the station cable lengths as out-
lined in the table on page 3-29. The ohm values are
loop measurements; feet (meter) values are the max-
imum one-way measurements from the equipment
cabinet.
