Cable Connections
3.4.2 CO Side Polyethylene Insulated Cable (PIC) Connection
³ To connect the CO side cable using the PIC stub
1. Slide the nut of the 3/4” strain relief supplied up the cable from the free end of
the stub.
2. From the inside of the shelf, pass the free end of the cable through the bottom
left-hand side.
3. Plug the male connectors into female receptacles TB1 and TB2, mounted in
the bottom left-hand corner of the shelf. For a diagram of the CO side terminal
blocks, refer to Figure 7 on page 36.
4. Take the remainder of the strain relief (the gland nut, chuck, neoprene
bushing, and body), and slide it onto 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 PIC stub and the incoming CO cable can now be
made according to the color coding of the CO cable.
For a listing of the color codes, refer to Table 2 on page 18.
For a view of CO side motherboard interconnections, refer to Figure 8 on page 37.
The PIC stub must be spliced to the incoming CO cable using a high-dielectric
splice case. All interconnections should be completely isolated from anything that
is, or could eventually become, referenced to Station ground.

Q
The shield of the CO cable must not be connected to Station ground.
The wires themselves should be tightly bundled together inside the
shelf using tie wraps, as shown for the PIC cable in instruction sheet
241-010008-001 Rev 2. This is to minimize the chance of a broken wire
touching an adjacent plug-in card.
