5.4.5.5 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.
Referring to the pin-out charts and Figure 5.4.5.5-1 below and Figure 5.4.5.4-1,
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
1. A shorter cable length between the WTIB and System DECT Base Stations will
decrease the possibility of data degradation.
2. 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.
