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....

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...

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.

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.

At each station location terminate station cables on 4-conductor modular jack 
assemblies. Although only one pair is required for...

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.

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.

†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...
