PLICING
Splicing consists of connecting the wire pairs of the HRE-506 cable stub to the main cable located in the splice
case, as shown in
below. The following sections contain step-by-step procedures for:
•
Preparing the stubs for splicing into the main cable, see
“Pre-Splicing Procedure” on page 35
.
•
Splicing the stubs into the main cable, see
“Splicing Procedure” on page 36
•
Dressing and taping the final splice in the splice case, see
“Post-Splicing Procedure” on page 37
.

Cable Stub Construction
While performing these three splicing procedures, maintain cable pair integrity when splicing stub pairs into the
main cable. The T1 lines must have correct cable connection. However, the HDSL units will compensates, if cable
pairs are reversed, but may provide false indications when trouble occurs. Follow normal procedures, as required.
Pre-Splicing Procedure
Perform the following steps to pre-splice the enclosure cable stub:
1
Strip a sufficient length of outer jacket, aluminum shield, and mylar sheath from the cable stub.
2
Strip the main cable, as required, by the cable manufacturer.
3
Install shield bonding connectors in accordance with standard practices.
4
To avoid split pairs, tie or band the ends of the Group 1 and Group 2 pairs. Cut off pair ends and the cable
butt to aid in the removal of grease.
5
Separate pairs between the tied ends and the cable butt to aid in the removal of grease.
Ground the HRE-506 enclosure before splicing the cable stubs into the main cable. The
grounding method discussed in
or an accepted local grounding
method must be in effect at all times to safeguard personnel.
The HRE-506 comes with a screened cable stub that is precut and capped.
The cable butt is considered to be the end of the cable stub most distant from the enclosure.
