Splicing Procedure
1 Splice the cable stub to the main cable using the wire identification information in Table 5 on page 27 and
Table 6 on page 28 .
2 Visually inspect each splice for split pairs, opens, and shorts.
3 Connect the CO side of the main cable to the CO side of the cable stub with a straight splice
(see
Figure 13 ).
4 Once the cables are connected, wrap the CO splice with aluminum tape or dress out the splice according to
local procedures.
5 Connect the field side of the cable stub to the field side of the main cable with a straight splice.
Maintenance personnel sometimes cross-splice defective pairs between units. These pairs are
referred to as “wandering pairs” and may cause problems.
