InstallationSYSTEM 
WIRING
System cabling may be routed concealed or visible as the installation
loc,ation requires.Good engineering practices must be observed andall applicable building codes must be adhered to.
Tables 
2-l through
2-5 and Figures 2-2 through 2-6 illustrate the system wiring.AC Power Connection
To apply AC power to the power supply,connect the AC power cord to
the electrical outlet which supplies the dedicated 117VAC 
@ 15 AMP
electrical power.
CAUTIONS:
.Employ a dedicated lI7VAC 15 AMP circuit,with a third-wire ground,
supplied to a standard electrical outlet (NEMA 
5-15R) for the AC
power connection.
.A plug-in powerline surge protector should be installed between
the power cord and the AC outlet.
.Do not connect the AC power cord until the installation has been
checked per the SYSTEM CHECKOUT instructions 
given.at the end
of this chapter.
Cable Clips
Each cabinet-mounted 50-pin male connector 
Is equipped with a
retaining clip.This clip is designed to secure the mated connection
once it is made.The clip does this by snapping into a slot on the
cable-mounted connector when it is pressed together with the 
cabinet-
mounted connector.This retaining clip must be pulled back slightly
to un-snap it before the connectors can be separated.
Line Connections
The common equipment interface connectionfor the outside lines is a
50-pin,male connector.A 25-pair cable,properly terminated, must be
connected from the common equipment connectorto the demarcation point
connector (typically a 
66M-xx connector).
CAUTION: To help insure that external overvoltage surges do not damage
the system,verify that gas discharge tubes or similar protection
devices are installed, and properly grounded,on all connected outside
lines.
Station Connections
The system supports the operation of the following stations:.
Executech II Multiline Telephone . LCD Speakerphone
.Single-line Keyset.Reused 3/8 Line Keyset
.32-Button Adjunct Feature Module . 40-Key DSS/BLF Console
.TO-Key DSS/BLF Console

							IMI 66-060
Installation
Connections between the common equipment and the stations are
typically via type 
66M-xx connector blocks which are cable.connected
to the common equipment SO-pin male connector.
The maximum distance
allowed from the common equipment to the station when using 
#24 gauge,
twisted-pair cable is:
. 1500 feet for multlllne 
keysets
. 3000 feet for single-line 
keysets
If spare conductors exist in the cables that are run between the
common equipment 
66M-XX connector block and the station jacks, it is a
good practice to connect them to earth ground.
Doing 
this may help
prevent them from inducing radio frequency and/or AC interference into
the system.
CAUTION: The polarity between the individual wires 
in a particular
voice or data pair 
is not critical; however, do not connect the voice
circuits to the data circuits.
IMPORTANT NOTE:
Station ports are programmed for the type of equipment
that is to be connected to them.Since an Executech II multiline
telephone 
1s required for Class Of Service Programming, this type of
equipment. must be installed at station port 10 and/or 11 for
programming purposes.
DSS/BLP Console Connections
A large number of consoles can be installed with a system by employing
all unused companion station ports and eight dedicated console ports.
.Model K2264 -forty (40) consoles
. Model K2296 
=fifty-six (56) consoles
The eight dedicated console ports are as follows:
 CONSOLE PORTSTATION PORT
CONSOLE PORT 1 STATION PORT 1
10aand10b1042aand42b142
llaandllb1143aand43b143
NOTE:In order to support a fully equipped system, two 70-key consoles
or one 70-key console and one 
40-key console are required for each
attendant.
Executive Consoles
The 32-Button Adjunct Feature Module can also be installed as a
companion to any station in the system.As such,it is connected into
the port that 
is data-paired with the companion station.
NOTE: Port pairing for the system is discussed Chapter 4.
Two different wiring methods can be employed.
1.As illustrated in Figure 2-2a,both the station and the data-paired
console can be connected separately to the 
station connector block.

							IMI 66-060
Installation2. As illustrated in Figure 
2-2b,common wiring for both the console
and the companion station can be employed to effect a wire-savings.When employed,
the following conditions must be considered.
. If common wiring is employed for the entire distance between the
station and the KSU,the maximum wire length using 824 AWG, 
twisted-
pair wire is limited to 1000 feet as opposed to the normal 1500 feet
limitation for station-wiring 
iHowever,if only 10 feet or less of
common wiring is employed between the station and a wall jack, the
normal 1500 feet limitation applies.
. Theauxiliary jack of the data-paired station cannot be used for
any custom-wired purpose.
Power Failure Station Connections
The system provides four tip and ring pairs connected to lines 1, 2,
3, and 4 as emergency,power failure circuits.These power failure
pairs are located as detailed on Table 2-4 and Figure 2-5.A power
failure pair is only active during a commercial AC power failure. An
industry standard,single-line telephone,such as a Comdial model
2500-xx,can be connected to a power failure pair and used to provide
communications capability until the AC power to the system is
restored.
Station Auxiliary Jack Connections
For those stations equipped with an auxiliary jack, pins 3 and 4 (tip
and ring leads) of this jack are connected to pins 1 and 6 of the
station line jack.A 6-conductor station line cord is used, and the
third pair is designated as the auxiliary-pair.
Refer to Figure 2-6 for an illustration of a typical auxiliary-pair
wiring connection,and note the following wiring considerations:
Wire a type 
62582-6 modular jack to be used as the station wall
- jack.
.Connect 3-pair cable between the station wall jack and an auxiliary
66M-xx connector block.
.Connect the voice-pair and data-pair from the auxiliary connector
block to the station connector block.
.Connect the auxiliary-pair from the auxiliary connector block to the
desired termination.
.Connect an appropriate line cord between the auxiliary jack and the
auxiliary source equipment.

Installation
A-Lead Control Device Connections
The common equipment can detect an A-lead (A and Al) control signal
when it is applied to lines 
13 - 16.An A-lead control device can be
bridge-connected to these lines via terminal clips on the J-4 station
connector block.Refer to Table 2-4 and Figure 2-5 for connection
details.
Data- Device Connections
When a serial data printer is used for SMDR and COS printout, or a
video display terminal (VDT) is used to perform class of service
programming,
connect the data device to terminal clips on the J-4
station connector block.
The distance between the device and the common equipment can be up to
500 feet in a quiet electrical environment.
Shielded cable may be
required at some sites for long 
runs.For longer distances, a limited
distance modem must be used to relay the data communications between
the common equipment and the data device.Refer to Table 2-4 for
connection details.
When preparing a cable for connection to a data device, refer to the
manufacturers manual for the equipment being interfaced, and make the
following wiring connections:
.Wire the common equipment RD line (data from printer to common
equipment) to the device TD (transmit data) output pin.
.Wire the common equipment TD (data to device from common equipment)
pin to the device RD (receive data) pin.
.Wire the common equipment SG (signal ground) pin to the device SG
(signal ground) pin.
.Wire the common equipment CTS (clear-to-send status from device to
common equipment) pin to the device RTS (request-to-send) output
pin.
NOTE:
The common equipment requires a positive voltage, with respect
to signal ground,in order to send data.
. If required,wire the common equipment RTS (request-to-send status
signal from the common equipment to the device) pin to the device
DSR (data-set-ready) input pin.
. If required,wire the common equipment PG (protective ground)
line(s) to the device protective ground pin(s). 
						

							IMI 66-060
InstallationData Format
Configure the data device to match the following data format and to
receive data at the baud rate that is set by COS programming.
. 7-bit data with no parity - fixed
. Baud rate of 1200 baud (default) -
can be changed through class of
service programming.
System Grounding
Executech common equipment has internal secondary surge protection 
on
all line ports.In order for this protection to be effective, the
common equipment cabinet and the power supply MUST be connected to a
reliable earth ground such as a metal cold water pipe or a building
frame ground.The grounding wire must be of 610 or 
f12 insulated,
solid copper and separate from the three-wire AC line cord.
A ground
stud is located on the common equipment cabinet and the power supply
cabinet for this purpose.
Conron Audible and Auxiliary Station Interface
Two sets of relay closure dry-contact points are available at the J-l
and J-2 station connector blocks.
. One set (J-l connections) provides a dry-contact closure whenever
any of the TELCO/PBX lines,connected to the common equipment, 
rir
.The other set (J-2 connections) provides a dry-contact closure
whenever system station 17 rings.
These contact closures track the ringing pattern in both cases.
The
contacts are closed during the ringing period and are open durin‘g the
silent period.
A typical connection is illustrated in Figure 
2-3.Refer to the
paragraph headed Area Paging Interface for a discussion for using
these terminals in this alternate paging function.
CAUTION: Do not exceed a 1 amp at 24 volts 
(.5 amp at 48 volts) load
on these control terminals.If the load requirements exceed this
limit,connect the load through an external slave relay.DO NOT
CONNECT THESE CONTROL TERMINALS DIRECTLY TO THE 
117VAC LINE.Area Paging Interface 
- Station PA Port
A station port can be configured by class of service programming to be
a PA port.As a PA port,it can be used to couple a station voicepath to an external device (see Chapter 3 for 
programming details)*
.The audio input of an external paging amplifier can be connected tothe audio pair of the station port as illustrated 
in Figure 2-4.
.The audio input connection mustbe isolated with a 600 ohm to 600

ohm audio matching transformer.Terminate the audio input of the
paging amplifier with a 620 ohm (nominal value) resistor.
. If station port 39 is programmed as a PA port,
the Common Audible
contact points are automatically reconfigured as PA enable
terminals.The contact closure now occurs when PA station 39 is
dialed.The normal common audible function, as discussed
previously,
is disabled as long as station 39 is a PA station.
. If station port 41 is programmed as a PA port, the Auxiliary Station
Interface (station 17 audible) contact points are automatically
reconfigured as PA enable terminals.The contact closure now occurs
when PA station 41 is dialed.The normal auxiliary station
interface function,as discussed previously,is disabled as long as
station 41 is a PA station.Area Paging Interface 
- Line Port
A line port can be configured by class of service programming to be an
AUXILIARY port.As an AUXILIARY port,it can be used to couple a
station voice path to an external device.This is done from any
station with that line presence pressing the proper line key to select
the AUXILIARY port.DTMF tones or dial pulses can be dialed through
the AUXILIARY port as needed.
.The audio input of an external paging amplifier can be connected to
the tip and ring leads of the line port.
.The audio input connection must be isolated with a 600 ohm to 600
ohm audio matching transformer.Terminate the audio input of the
paging amplifier with a 620 ohm (nominal value) resistor.
A DTMF tone select,zone-paging amplifier can be employed if desired.
If used,the zone-select code must be dialed after the AUXILIARY port
line select key is pressed.

Bybrid/Key System Configuration
The system can be configured to-operate as either a hybrid system or
as a key system.
. The common equipment is shipped from the factory as a key system
(KF).
. Configuration is by way of a wire strap placed between clip
terminals 27 and 28 of station connector block J-4.To convert to a
hybrid (MF) system, add the strap.
The KF and MF designations are equipment type categories as 
stipulated
in FCC rules and regulations, Part 68,and appear as part of the FCC
Registration Number on the equipment label.The appropriate
registration number must be reported to the telephone company at the
time of connection along with other FCC mandated information. (Refer
to Installer/User Information Regarding FCC Rules and Regulations
found in Chapter 1 of this manual.)
The hybrid configuration enables a PBX feature which may incur a
higher monthly tariff to the telephone company.This feature allows
dial access to (automatic selection of) outgoing lines.The specific
Executech feature that is enabled by the hybrid configuration is:
.Line Group (Including Dial Access)Music Interface
If music is to be part of the system,connect a KX registered music
source to the common equipment input jack (phono jack) provided for
this 
purpose-The impedance of this input is approximately 500 ohms.
Level adjustment of the music source may be necessary.This may be
done during system checkout.Cassette Tape Recorder Interface
A customer provided, audio cassette,tape recorder can be connected to
the music interface jack.Class of service programming can be both
stored and loaded via the recorder through this interface.
This
action is controlled from station 10 or 11 as detailed in Chapter 3,
System Programming.
