to completion.
Splicing Procedure
Certain applications involve splicing the cables on the HRE-506. The following section describes splicing
procedures and wire list information.
1 Splice the cable stub to the main cable using the wire identification information in Table 3 on page 31 .
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, as shown in
Figure 16 .

When the air temperature is low, warm the cable pairs to aid in removing grease by cleaning the
stub in a heated enclosure or by using a heat gun to apply warm air to the pairs. Avoid applying
excessive heat, which could deform the insulation on the pairs.
Maintenance personnel sometimes cross-splice defective pairs between units. These pairs are
referred to as wandering pairs and may cause problems.
