							The 6 Port CO Module must be installed in the last available Expansion Buss 
Connector on the CPU Module. That is, if a 6 Port CO Module is installed on JP3 a 
3X8 Expansion Module will not function if installed on JP4. 
So, if a 3X8 Expansion Module is added after a 6 Port CO Module was previously 
added, the 6 Port CO Module must be removed Tom JP3, the new 3X8 Module 
installed to JP3 and the 6 Port CO Module reinstalled onto JP4. f‘

the CPU Module. 
11. Use one of the screws removed in step 5 to secure the Standard MOH/BGM Module in place. 
12. Replace KSU cover and secure with cover screws. 
13. Restore KSU power. 
6.5 Grounding Requirements 
The KSU must be properly grounded. The power cord third-wire ground is sufficient for this KSU. DO 
NOT use a three-wire to two-wire adapter when connecting AC power as the AC cord third-wire ground is 
the only KSU ground source. Test the AC receptacle for proper wiring and presence of ground. 
NOTE: According to UL 1459, “the attachment-plug receptacle in the vicinity of the product or system are 
all to be of a grounding type, and the grounding conductors serving these receptacles are to be connected 
to earth ,ggozmd at the service equipment. ”

							6.6 Voltage Surge/Spike Protection 
To reduce the effects of AC voltage surges and spikes that may cause system malfunctions, false logic, 
and/or damage to the electronic components, it is recommended that a surge/spike protector be installed. 
Check the manufacturer’s specifications to ensure that the device meets the following requirementsi 
0 
Clamp voltage transients at 300 volts within 5 nanoseconds when exposed to wave-forms as described 
; 
in the ANSI/IEEE Standard C62.4 1- 1980 (IEEE 587). 
l Reduce RFVEMI noise by at least 20dB at frequencies between 5kHz and 30MI-l~. 
6.7 230VAC Operation 
When installing the KSU in a location that will use a 230VAC power source it is necessary to strap the AC 
power transformer for 230VAC operation. The transformer is equipped with three primary winding tap 
leads colored Red, Brown and Black. The Black and Brown leads are used for 117VAC operation. (This is 
the factory wired configuration.) The Black and Red leads are used for 230VAC operation. 
Use the steps below to make the 230 volt AC field strap adjustment: 
1. 
3 
-. 
3. 
4. 
5. 
6. 
7. Make sure that the KSU power switch is turned off and that the KSU power cord is not connected to 
any AC power receptacle. 
Since the KSU is shipped configured for 117VAC operation, locate the Brown power transformer lead 
and cut it mid-way between the power transformer and the KSU power switch. 
Tape (or otherwise insulate) and store the brown lead extending from the power transformer. 
Strip approximately 10 mm (half-inch) of insulation f?om the end of the remaining portion of the 
Brown lead (going toward KSU power switch). 
Locate the factory insulated Red transformer lead and cut the insulated tip off. 
Strip approximately 10 mm (half-inch) of insulation from the end of the remaining portion of the Red 
lead. 
Using an appropriate splice connector (wire-nut, etc. in conformance to local electrical code), join the 
Red and Brown leads and insulate. 
6.8 Connecting CO Lines 
6.8.1 CO lines connections for the 3X8 Standard and 3X8 Expansion Module(s): 
1. The CO line connections (as well as station connections) are made to the 3X8 Standard Module and 
Expansion Module(s) via the 25 pair connector located along the bottom edge of the installed module. . 
(Refer to the illustrations in the table for cable pair designations.) i.. 
7 -. Once the 25 pair cable is terminated on an industry standard 66M1-50 block. cross-connect (jumper .. 
wire) should be used to extend the CO line pair from the terminal block to the Telco Demarcation

							block. Plan to use at least one pair of bridging clips for kach CO line connected so that service of any 
one specific CO line is simplified. 
6.8.2 CO lines connections for the 6 Port CO Module. 
1. CO line interface to the 6 Port CO Module is made through two RJ25 type modular connectors on the 
6 Port CO Module located along the bottom edge of the installed moduIe: CO line ports l-3 of the 6 
Port CO Module are connected through RJ25 connector “CO I-3” (positioned toward the left/center of 
the installed module) and ports 4-6 of the 6 Port CO Module are connected through RJ25 connector 
“CO 4-6” (positioned toward the right/center of the installed module). 
3 
I. The 6 Port CO Module is shipped with two 3-pair line cords and two 3-pair terminal blocks for 
connection on the MDF. Once terminated the individual pairs of the 3-pair terminal blocks are 
extended to the Telco Demarcation block. Plan to use at least on pair of bridging clips for each CO line 
connected so that service of any one specific CO line is simplified.

a. It is the installers responsibility to assure that CO line connections are made in such a way that proper 
CO Hunting will sequence f?om the first CO line button to the last, in order on key telephones. 
If incoming CO lines Hunt@om a main telephone number and are also used for 
outgoing (both-wq CO line) service, always prioritize the incoming line order so 
that the last choice incoming trunks appear on the higher number CO line 
positions. This is because the system automatically selects idle trunks for outgoing 
calls, by searching@om CO line 
12, to CO line I I, and so on to CO line I. This 
technique may avoid a “head-on ” or “Glare ” condition where a user trying to 
place an outgoing call inadvertently answers a ringing line. 
b. Typically the Telco service provider provides lightning protection at tfie’ premise at the service 
entrance. However, if there is no lightning protection or the installation involves customer owned cable 
linking buildings together such that this equipment is installed at a remote site with outside plant wiring 
connected directly to any port of the system; the installation must include lightning protection. Install

							gas discharge tubes with silicon avalanche suppressers to ground on each CO line and any port 
extended from the KSU over outside plant wiring. This must be done external to the system. 
C. Test each CO Line at the MDF for dial tone, correct ringing sequence, Telco number assignment and 
polarity. 
Note: The System CO Line inter$ace circuits are polarity guarded and will properly DTMF 
signal on an)r DTMF capable CO line. 
d. Once the system is powered up, the following CO Line interface/signaling characteristics. must be 
verified in System/Trunks Data Base Programming: 
. 
CO Line Group programming 
. 
DTMF ON Tone Duration 
. 
CO or PBX CO line 
. 
Flash Time (Call Waiting, Centrex, PBX)

6.9 Station Cabling 
Floor plans should be developed to aid in proper station cabling in a star (home run) configuration from the 
KSU. The cables are run horn the station locations to the STN block at the MDF. Refer to KSU Station 
Cable Dia_m. 
Both ends of each cable should be labeled with the station’s circuit number. The circuit number designates 
the station port position in the KSU. 
When the system is initialized, the intercom numbers are assigned in order h-om port 1 (intercom number 
10) to port 24 (intercom number 33). 
6.9.1 Running Cable 
NOTE: It is recommended that three-pair cable andfour-conductor (minimum) modular jacks be usedfor 
all station connections. 
From the MDF location, run unshielded. three-pair (six-conductor) twisted cable to all key telephone 
locations and DTMF single-line telephone locations. Follow these guidelines: 
. 
Install proper type cable for the application according to the National Electrical Code and local 
building codes. 
. 
Avoid cable runs parallel to fluorescent light fixtures or AC lines not in conduit. If these obstacles are 
unavoidable. run the cables across them at right angles. 
. 
Do not run station cables inside electrical conduit already occupied by AC-wiring. (To do so is a 
violation of the National Electrical Code.) 
140 Installation & Maintenance Manual Revision 3 July 6: 1997  
						

							. Do not run station cables near equipment with electric motors or through strong magnetic fields, such 
as those generated 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. 
. If using multi-pair (25-pair) cable runs to multiple station locations do not include AC ringing 
single-line sets, AC-ringing auxiliary equipment, or CO lines in a cable being used for key telephones. 
Key telephones should always he isolated in separate dedicated cable runs. 
. 
Do not exceed the measurements for the station cable lengths (using 26AWG wire) listed in the Loop 
Limit chart. The ohm values are loop measurements; feet (meter) values are the maximum one-wav 
distances from the KSU. (See “Station Loop Resistance Test”). 
6.9.2 Terminating The Cables at Station Locations: 
Terminate key telephones and DTMF single-line telephone cables on four-conductor modular jack 
assemblies at each station location.(4 conductors provide 2 pair wired to the telephone. Although only one 
pair is required for key telephone operation, the second pair is wired through to the ADP jack for a variety 
of applications at the desktop.) (For exceptions to this, refer to the NOTE under “Running Cable” above.) 
I Blue/White 
1 Red

Do not mount the modular jack assemblies on the wall at this time; they will be wall mounted later when 
the station instruments are installed. 
1. Since the digital station equipment is not polarity sensitive reversing the digital telephone pair has 
no affect on operation. 
3 
-. The Station Interface circuits are current limited and are not fused. 
6.9.3 Station Loop Resistance Test: 
Perform the loop resistance test for each station cable individually. 
1. No equipment can be connected to the cable pair to be tested. If a jumper &ire is already in place it 
must be removed for this test (or unplug the Amphenol type connector from the associated 3X8 
Module). Be sure that the station instrument is not connected to the modular jack assembly. 
3 
-. Place a short across the RED and GREEN wires on the modular jack assembly at the station end.

							:- 
3. 
At the MDF, measure the resistance across the WHIT%/BLUE and BLUE/WHITE wires of the cable 
under test. The reading should not exceed the limits (for twisted pair, unshielded 26 AWG cable) listed 
in the table below (ohm values are the loop measurements; feet/meter values are the maximum 
one-way measurements from the KSU). 
Analog Adapter (from KSU to SLT) 
Note: the 2-Port SLT adapter may be 
Installed anywhere inbetween. 180 ohms 650 ft. (195 m) 
NOTE: Excessive and/or improperly made connections increase the resistance of a cable, which reduces 
the allowable cable run length. 
4. Remove the short after the test is complete. 
5. Repeat this test for each station cable. 
6. Reconnect the station cable jump wires (or plug in the 3X8 Module connector). 
7. Plug in the instruments.

configuration is used for High Profile Desk Mounting. 
142 Installation & Maintenance Manual Revision 2 July 6. 1997  
						

							“V. 
Remove the components f?om the carton and determine which mounting components are required. Most 
telephones will be installed using both mounting wedges (small & large) for the High Profile Mounted 
position. Reference the illustration at left 
and 
1. attach the Base Mount wedges. 
The small wedge is always used for 
the various telephone mounting 
positions. 
2. The small wedge has locking tabs at 
one end and hooks at the other end 
used in a hinging fashion to attach 
the small wedge to the telephone. 
When the telephone is to be wall mounted: 
1. Remove the two small screws that secure the small and large wedges together. 
3  a. Store the larger wedge for possible use later. (The large wedge is not used 
when wall mounting the key telephone.) 
3. Then position the smaller wedge as in the illustration at the right for wall 
mounting. Once in position, the smaller wedge and key telephone bottom 
housing provide for standard 630 type wall mount wail jacks. 
When the key telephone is to be desk mounted in the Low Profile position: 
1. Remove the two small screws that secure the small and large wedges together. 
2. Store the larger wedge for possible use later. (The large wedge is not used 
when mounting the key telephone in the Low Profile position.) 
3. Position the smaller wedge as illustrated below. 
Note when using this mounting position it is important that the line cord be 
channeled through the slots in the telephone bottom housing such that the smaller 
place when in position. wedge locks them in
