4.2 Pull Cable
Pull the cable from the MCU location (usually in the telephone equipment room) to the
Base Station locations designated on the floor plans.
If the cabling exits the building, consult the telephone system manual, the
NEC, and local codes for instructions on providing lightning and other over-
current protection.
When cabling an external Base Station or a Base Station with wiring that
exits the building, protect all Base Station wiring with the Quick Clip Fuse
(Illinois Tool Works, Linx Division, SCP-2X2) before bridging with other
Base Station power leads.
Run all cable before attaching the RJ-45 connectors to the Base Stations. Label both the
demarcation block end and the Base Station end of each wire with the Base Station
number using a wire tie marker or other form of marker.
! !
Remove bridge taps, multiples, or "Y" connections to the Base Station wires;
these will cause data transmission errors.
The area above some suspended ceilings is used as an environmental air
plenum. The National Electric Code requires that wire installed in plenums
be rated for plenum installation.
4.3 Terminate Cable at Base Station Locations
After running the wire to the Base Station location, terminate the wire using an RJ-45
modular crimp-on plug. Connect the data pair to pins 1 and 2 and the power pair to pins
7 and 8.
If the connection uses more than two pair, refer to the table on the following page.
! ! To avoid damage to the connectors or crimps, be sure to run the wire to the
Base Station before connecting the RJ-45 connectors.
