2.6 Attach KSU Cables
The 616 requires one 24-pair connectorized cable
(available from Sprint North Supply) for terminating
the 3 CO lines and 8 extensions.
To connect the cable, follow these steps:
1) Attach the amphenol-type connector on one end
of the cable to the connector on the 616 KSU.
2) Strip the opposite end of the cable, exposing a
sufficient amount of wiring for connection to
the terminal block.
3) Follow the color code illustrated in Figure 3-4
to connect the cable to the terminal block.
2.7 Station Cabling
Protegé® stations require a star (home run) configu-
ration from the KSU. Develop a floor plan before
running cable to avoid problems such as overlooking
or duplicating cable runs. Label both ends of each
cable for easy identification.
Protegé stations require 24 AWG twisted-pair
cabling. Each station uses one twisted pair. At least
two-pair twisted cable is recommended for all sta-
tions. The additional pair may be used to replace a
bad wire pair. Each station cable should be dedicated
to one telephone instrument. Sharing one cable
between two instruments is not recommended.
2.8 Running Station Cable
From the MDF, run standard 24 AWG two-pair
twisted cable (4 conductor) to each station position.
Follow these guidelines:
1) Install proper type cable for the application
according to the National Electrical Code and
local building codes.
2) 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.
3) Do not run station cables inside electrical conduit
already occupied by AC power cable. (To do so is
a violation of the National Electrical Code).
4) Do not run 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.
5) Do not place station cables where they can be
stepped on or where they can be rolled over by
office furniture.
6) Avoid using multi-pair (e.g. 25-pair) cable runs to
multiple station locations. If multi-pair "feeder"
cables are used, do not include AC-ringing sin-
gle-line sets, AC-ringing auxiliary equipment, or
CO lines in a cable used for digital keysets.
7) Do not exceed the loop limit measurement
(using 24 AWG wire) for the station cable-
lengths as outlined in Table 3-3.
