4.2.2 Terminate Wire to Base Stations
For ease of maintenance, the Base Station wiring should conform to one of several
standardized premises distribution systems. The following section describes the common
wiring standards for premises distribution systems using 4-pair wire and 8-conductor
modular (RJ45) connectors. We recommend EIA 568B, also known as WECO or AT&T
258A wiring standard.
The following wiring standards are NOT recommended:
USOC: the data signals do not reside on the same wire pair
356A: the Base Station power pair is open
10 BASE-T: in its most basic form, the Base Station power pair is open
A Link 150 to Base Station connection using the recommended standard should be wired
as shown in the following table.

The pins on an 8-pin modular plug viewed with the latching bar at the bottom
(see illustration) are numbered from 1 at the left to 8 at the right. When using
jacks, wire both ends using the same standard. Use straight-through patch
cables on each end.
