3.4.1 Station Side Cable Connections
³ To install the Station side cable connections:
1. Slide the free end of the Station cable through the nut of one of the 1/2” strain
reliefs provided.
2. Feed the free end of the cable through the upper hole on the upper right-hand
side of the shelf, from the inside to the outside.
3. Plug the male 18-pin connectors into the female receptacles TB1 and TB2.
Then plug the small 2-pin connector P18 into the male connector J18. Pass
the cable of J18 under the cable clamp shown in figure 5 (item 68). J18 is
used to provide a contact closure in case of a failure of the internal power
sources. For a diagram of the Station side terminal block and connector, refer
to Figure 5 on page 33.
4. Take the remainder of the strain relief (gland nut, chuck, neoprene bushing,
and body and slide it up the cable from the free end outside the shelf to the
shelf opening. Secure the cable by holding the nut inside the shelf and
tightening the grip by turning the gland nut.
5. Connections between the Station cable and the site equipment cables can
now be made according to the color coding.
For a listing of the color codes, refer to Table 2 on page 18.
For a view of Station side motherboard interconnections, refer to Figure 6 on
page 34.

or from sagging into the isolation gap between the Station and CO side
motherboards.
