3. Installing 3 x 8 Modules 
Figure 3-4: DHS-E CPU Board
The DHS-E  comes with two pre-installed 3 x 8 modules. Each additional 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 3 x 8 module.
The 6-Port CO Module CANNOT be used in the DHS-E system.

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 Table 3-12). 
The 3 x 8 module is installed to expand system capacity and is housed in the KSU in 
stacking fashion over the initial two 3 x 8 modules. Four additional 3 x 8 modules 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, and the KSU cover is removed.
2. Connect grounded wrist strap to a suitable earth ground.
3. Locate the screws used to secure the 3 x 8 module.
4. Remove one of the module-securing screws only (so the existing board stays in place, 
and retain the screw for later use).
5. Insert one of the stand-off posts into the screw position where the screw from Step 5 
was removed.
6. Tighten securely by hand, then finish tightening with 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.
7. Repeat Steps 4 through 6, until all module screws are replaced with stand-off posts.
8. 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.
9. Once mounted, carefully insert the bus ribbon cable into the next available bus 
connector on the CPU board.
10. Connect the amphenol-ended cable to the connector on the 3 x 8 module.
11. Secure the cable in place with a clamp or cable tie.
12. Replace KSU cover and secure with cover screws, and restore KSU power when all 
wiring is complete. Or continue with the installation process.
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).

5. Terminating Connections
3 x 8 Module(s)
1. The CO line connections (as well as station connections) are made to the 3 x 8 Module 
via the male 25-pair connector located along the edge of the installed module (refer 
to Table 3-12
).
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. Plan to use at least one pair of bridging clips for 
each CO line connected so that service of any one specific CO line is simplified.

Conditions
†It is the installer’s responsibility to assure that CO line connections are made in such a 
way that proper CO Hunting will sequence from the first CO line button to the last, in 
order on key telephones.
†Typically, the Telco service provider provides lightning protection on the premises at 
the service entrance.
†Test each CO Line at the MDF for dial tone, correct ringing sequence, Telco number 
assignment and polarity.
6. 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 from the station locations to the STN 
block at the MDF. 
Both ends of each cable should be labeled with the stations 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 from Port-1 
(intercom number 10) to Port-24 (intercom number 33) as each Module is installed (refer 
to Table 3-12).
Running Cable
From the MDF location, run unshielded, 3-pair (6-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.
†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 
If incoming CO lines Hunt from a main telephone number and are also used for outgoing 
(both-way 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 from CO line 18, to CO line 
17, and so on to CO line 1. This technique may avoid a head-on or Glare condition where a 
user trying to place an outgoing call inadvertently answers a ringing line.
Use shielded cable if RF1/EF1 is expected. 
						

							DHS-E Installation3-25
used for key telephones. Key telephones should always be isolated in separate 
dedicated cable runs.
†Do not exceed the measurements for the station cable lengths (using 26AWG wire) 
listed in Ta b l e  3 - 6. The ohm values are loop measurements; feet (meter) values are the 
maximum one-way distances from the KSU.
Terminating Cables at Station Locations
At each station location terminate station cables on 4-conductor modular jack 
assemblies. 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 Table 3-13.
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.
7. Key Telephones Installation 
Key telephones may be mounted with three different orientations: Low Profile Desk 
Mount, High Profile Desk Mount or Wall Mounted. Packaged inside each key telephone 
carton are the following components:
†Key telephone
†Key telephone handset
†7-ft. line cord
†4-in. line cord (for wall mounting)
†12-ft. handset cord
†Small base-wedge mount assembly
†Large base-wedge mount assembly
It is recommended that a minimum of 3-pair cable and a minimum of 4-conductor modular 
jacks be used for all station connections.

Cable Conductor Jack Wire Color Designation
White/Blue Green Telephone voice and 
data XT lead
Blue/White Red Telephone voice and 
data XR lead
White/Orange Black ADP Jack Tip lead
Orange/White Yellow ADP Jack Ring lead
Since the digital station equipment is not polarity sensitive, reversing the digital telephone 
pair has no affect on operation. The Station Interface circuits are current limited and are 
not fused. 
						

							3-26DHS-E Installation
Remove the components from the carton and determine which mounting components 
are required. Most telephones are installed with both mounting wedges. 
High Profile Mount 
For the High Profile Mounted position, reference the illustration below and attach the 
Base Mount wedges.
Figure 3-6: High Profile Mount
1. 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.
Wall Mount 
When the telephone is to be Wall Mounted:
Figure 3-7: Wall Mount
The two wedge mount assemblies (large and small) are affixed at the factory. This 
configuration is used for High Profile Desk Mounting. 
						

							DHS-E Installation3-27
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 wall 
mounting the key telephone).
3. 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 wall jacks.
Low Profile Mount 
When the key telephone is to be desk mounted in the Low Profile position:
Figure 3-8: Low Profile Mount
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.
When using the Low Profile mounting position, it is important that the line cord be 
channeled through the slots in the telephone bottom housing, such that the smaller 
wedge locks them in place when in position.
Key Telephone Modular Jacks 
Each key telephone has two modular jack connectors on the underside of the instrument. 
Both are located in a recessed connector cavity. When the telephone is held so that the 
rubber anti-skid feet are downward (no mounting wedge installed), the modular jacks 
face one another in the cavity. The modular jack at the left side of the cavity is the ADP 
connector and may be connected to an analog device at the desktop. The ADP jack is only 
active when connected for operation at the MDF. The modular jack at the right side of the 
cavity is the KSU jack and should be connected to the wall jack and station cabling for 
connection to the system KSU (refer to Figure 3-9). 
						

							3-28DHS-E Installation
Figure 3-9: Key Telephone Modular Jack Locations
†ADP Jack - When wired at the MDF, the second pair of the telephone line cord/cable 
will activate this jack for any analog device function. This jack and wiring are 
completely independent of the key telephone operation and may be used for system 
resources. This is not FCC listed.
†KSU Jack - Connect the station cable line cord here. Two pair are provided. The first 
pair is all that is required for telephone voice and data. The second pair is looped to 
the ADP jack for use of analog devices at the desktop.

9. Press Clear to exit the Programming Mode.
 9. SMDR/SMDA (Output Device)
The output device or the Station Message Detail Recording (SMDR) must meet the 
requirements and match the RS232C pin-out described below.
To connect an output device to the KSU:
1. Match the baud rates on the output device and the system. 
2. Turn ON the AC power to both the device and the system before connecting the 
RS232C cable to Port-2 on the KSU. This prevents any electrical surges from being 
transmitted by the interface.
3. Carefully connect the RS232C DB-9 male end of the interface cable from the device to 
the SMDR RS232C DB-9 female connector located at the bottom edge toward the left 
of the Option Module.
The SMDR serial port output is one way to the printer or other Call Accounting device.
DSS Owner:
bksp              next                  chg
The RS232C cable connecting the SMDR device to the KSU must not exceed 50 feet (15 
meters) in length. 
The KSU end is considered DCE and the printer, or other Call Accounting Device is DTE.
