Splicing Procedure
Certain applications involve splicing the cables on the HRE-454. The following section describes splicing
procedures and wire list information.
1
Splice the cable stub to the main cable using the diagram in
and the wire identification information
in:
–
Table 8, “HRE-454, HRU-412, and HRU-402 Wire List,” on page 44
–
Table 9, “HRE-454 and ERU-412 List 2 Wire List,” on page 46
–
Table 10, “HRE-454 (HRU-512, HRU-612, and H2TU-R-402) Wire List,” on page 47
–
Table 11, “HRE-454 (HDU-451, HDU-404, and EDU-451) Wire List,” on page 49
–
Table 12, “HRE-454 List 5 and List 6 (HLU-431 and HLU-432) Wire List,” on page 51
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.
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.
6
Once the cables are connected, wrap the field splice with aluminum tape as shown in or dress out the splice
according to local procedures.
7
Repair or correct defective or wandering pairs before closing the splice; otherwise, the color code sequence
of the cable stub in relation to the pair count or the main cable will no longer be valid.
8
Roll back and tape the screen divider from the cable stub.
9
Perform any cable tests required by local practice.
Maintenance personnel sometimes cross-splice defective pairs between units. These pairs are
referred to as wandering pairs and may cause problems.
ADC highly recommends that you maintain cable pair integrity on the HDSL and
T1/G.703 sides.
