3 x 8 Module
The 3 x 8 module requires one 25-pair amphenol type (male) ended station cable to 
extend the interface ports to the MDF. The station cable is plugged into the female 
amphenol connector at the base (orientation assumes a properly mounted KSU) of the 
3x8 module.
It is very important that the KSU be correctly mounted to allow proper 
power supply heat dissipation.
System power should be OFF before plugging in the station cable or while working on the 
station punch-down block. (Although each port is over-current protected, unnecessary 
shorting should be avoided).

Figure 2-12: DHS Components
The cable is then routed out of the KSU through an opening at the lower left of the KSU 
housing. A cable restraint clamp is provided and may be used to secure cables exiting the 
KSU. The 25-pair cable is then terminated on a punch-down terminal block on the MDF. 
Refer to Figure 2-19: Wiring Designations for 3 x 8 Modules. 
The 3 x 8 module is installed to expand system capacity and is housed in the KSU in 
stacking fashion over the initial 3 x 8 module. Three 3 x 8 modules maximum can be 
installed in the KSU. The 3 x 8 module is shipped with four stand-off mounting posts. 
Follow these steps when installing a 3 x 8 module:
1. Be sure that KSU power is turned OFF.
2. Remove the KSU cover.
3. Connect grounded wrist strap to a suitable earth ground.
4. Locate the screws used to secure the 3 x 8 module or 6-Port CO Module.
The 6-Port CO Module must be installed in the last available expansion bus connector on 
the CPU Module. That is, if a 6-Port CO Module is installed on (JP3) a 3 x 8 module will not 
function if installed on (JP4). So, if a 3 x 8 module is added after a 6-Port CO Module was 
previously added, the 6-Port CO Module must be removed from (JP3), the new 3 x 8 module 
installed to (JP3) and the 6-Port CO Module reinstalled onto (JP4).

and retain the screw for later use.
6. Insert one of the stand-off posts into the screw position where the screw from Step 5 
was removed.
7. Tighten securely by hand, then snug tight using a small hand tool. It is very important 
not to over-tighten any screw or stand-off post as damage to the board may occur.
8. Repeat Steps 5 through 7, until all module screws are replaced with stand-off posts.
9. Position the new 3 x 8 module over the stand-off posts installed and use the screws 
removed in the previous steps to secure it in place on the stand-off posts.
10. Once mounted, carefully insert the bus ribbon cable into the next available bus 
connector on the CPU board.
11. Connect the amphenol-ended cable to the connector on the 3 x 8 module.
12. Secure cable in place with a clamp or cable tie.
13. Replace KSU cover and secure with cover screws, and restore KSU power when all 
wiring is complete. Or continue with the installation process.

6-Port CO Module
The 6-Port CO Module is installed to increase system capacity of CO lines. The 6-Port CO 
Module is shipped with two 6-conductor cords, two surface-mount modular jacks and 
four stand-off posts. Regardless of how many 3 x 8 modules are installed, only one 6-Port 
CO Module may be installed. The 6-Port CO Module must be the last module installed. For 
example, if a 6-Port CO Module is first installed as the first Expansion Module (JP3), and a 
3 x 8 module is then installed, the 6-Port CO Module must be moved to the last expansion 
position (JP4). 
Figure 2-14: 6-Port CO Module
Follow these steps when installing the 6-Port CO Module: 
1. Be sure that KSU power is turned OFF, and the KSU cover is removed.
2. Connect grounded wrist strap to a suitable earth ground.
3. Locate the screws that secure the 3 x 8 module already in place, and remove one of 
the module securing screws only so the existing board stays in place. Retain the 
removed screw.
4. Insert one of the supplied stand-off posts into the screw position where the screw 
from Step 3 was removed.
5. Tighten securely by hand, finish tightening using a small hand tool. It is very 
important not to over-tighten any screw or stand-off post as damage to the board 
may occur.
6. Repeat Steps 3 through 5 until all module screws are replaced with stand-off posts.
7. Position the 6-Port CO Module over the stand-off posts installed and use the screws 
removed in that process to secure it in place on the stand-off posts.
8. Once mounted, carefully insert the bus ribbon cable into the next available 
expansion bus connector on the CPU Module. When the Option Module is installed, it 
is necessary to remove the Option Module screws and lift the Option Module away 
from the CPU Module for clear access to the CPU module bus connectors (JP3 and 
JP4).

Option Module
The Option Module provides advanced call processing features like External Call Forward, 
Automatic Busy Redial, etc. (Generally, features that require enhanced call monitoring via 
Tone Detectors and DTMF receivers). The Option Module is equipped with two DTMF 
receivers and two Tone Detectors. In addition, the Option Module provides two music 
source inputs (one that replaces the Standard MOH/BGM Module), one External Page 
Zone port and one Loud Bell Control contact.
Follow these steps when installing the Option Module:
1. Be sure that KSU power is turned OFF, and cover is removed.
2. Connect grounded wrist strap to a suitable earth ground.
3. Locate the Standard MOH/BGM Module already in place. Notice that there is one 
screw that secures the Standard MOH/BGM Module to the CPU Module.
4. Remove the MOH/BGM Module screw and MOH/BGM Module. Then remove the 
short stand-off post used to mount the Standard MOH/BGM Module. Retain these 
pieces in the event that the Option Module is to be eliminated and standard MOH/
BGM operation is again desired.
5. Install one of the stand-off posts supplied with the Option Module into the position 
previously occupied by the short stand-off post. Use Step 8 as a guide for tightening 
the stand-off post. Locate the remaining three screws used to secure the CPU 
Module.
6. Remove one of the module securing screws at a time, so that the CPU Module stays in 
place, and retain the removed screw.
7. Insert one of the Option Module stand-off posts into the screw position where the 
screw from Step 6 was removed.
8. Tighten securely by hand, then snug tight using a small hand tool. It is very important 
not to over-tighten any screw or stand-off post as damage to the module may occur.
9. Repeat Steps 6 through 8 until all module screws are replaced with stand-off posts.
10. Position the Option Module over the stand-off posts installed such that the ribbon 
cable and connector are oriented at the top right of the module (Assuming correct 
KSU installation).
11. Locate the Option Module connector located on the CPU Module labeled “JP1” and 
carefully attach the Option Module ribbon cable to JP1 assuring that all connector 
pins are properly aligned.
12. Use the screws retained in Step 6 to secure the Option Module to the stand-off posts 
installed.
13. Replace KSU cover and secure with cover screws.
14. Restore KSU power when all wiring is complete, or continue with the 
installationprocess.
It is very important that all pins make contact to the connector and that no pins become 
bent in this process

6. Terminating Connections
3 x 8 Module(s)
1. The CO line connections (as well as station connections) are made to the 3 x 8 
Standard Module and Expansion Module(s) via the 25-pair connector located along 
the bottom edge of the installed module. Refer to Figure 2-19: Wiring Designations for 
3 x 8 Modules.
2. 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.  
						

							DHS Installation2-37
Figure 2-19: Wiring Designations for 3 x 8 Modules 
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 
module. CO line ports (1-3) of the 6-Port CO Module are connected through RJ25 
connector CO 1-3 (positioned toward the left/center of the installed module) and CO 
line 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).
2. 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.
