Installation of Station Wiring And Associated
Hardware
Installing Station Cables
The station labels shown in Figure 4-1 must be installed on each end of
a 25-pair station cable. The labels are provided with the 201A cabIe/jack
station labels (Figure 3-42). The labels must match the labels that were
previously installed at the cross-connect field. For example, if the cable
plugs into a 110-type terminal block/66-type connecting block connector
with jacks labeled 1 through 6, the cable label must be numbered 1
through 6 (see Note).
Note: If cable/jack station labels are not available, the information
can be written on the cable connector with a felt-tipped pen.

Figure 4-1. 25-Pair Station Cable Labels
Install the station cables between the equipment room cross-connect
field and the site, satellite, or adapter locations. If 25-pair cables are run
from the equipment room to the satellite location, A25B (for 66-type
connecting blocks) or A25D (for 110-type terminal blocks) cables are
used. If multiple 25-pair staggered finger station cables (male to male)
are to be run from the equipment room to the satellite location, B25A
