Ferrite Core Installation
A ferrite core is provided in the packaging of the System DECT Base Station. When properly installed, the
ferrite core reduces Electro-Magnetic Interference from the Base Station. The Ferrite core should be installed
on each cable that is connected to the WTIB as close to the WTIB connector as possible. Using RJ45
terminate CAT3 cable, wrap the Ferrite core as shown in Figure 4.4.5.4-1.

WTIB Wiring
Each Base Station port on the WTIB is terminated to an RJ45 connector wired as shown in the pin-out chart
below. Separate wiring is required for the TX and RX pairs. Power is delivered from the WTIB to the Base
Station over the simplex circuit formed by the TX and RX pairs.
Refer to the pin-out charts and Figure 4.4.5.5-1 below and Figure 4.4.5.4-1,
Plug RJ45 terminated cable with the Ferrite core into the appropriate WTIB connector.
Wire each WTIB RJ45 TX and RX pair to the System DECT Base Station termination point using
CAT3 or better wiring. The maximum total wire length is 600M/1.9Kft of 22 AWG.
Tag or number wiring for maintenance.
NOTE
A shorter cable length between the WTIB and System DECT Base Stations will decrease the possibility of
data degradation.
For best operation, all wiring from the WTIB to the Base Stations should use unshielded twisted pair wiring (at
least Cat 3) of a consistent gauge and kept at the shortest length possible.
