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 and 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.
Post-splicing Procedure
The post-splice procedure involves the following steps:
1
Starting at the cable-stub butt of the CO cable stub, wrap the pairs on one side of the screen with
3
/
4
-inch,
self-bonding rubber tape. Overlap the tape by one-half its width, as shown in
.
2
Repeat
, wrapping the pairs on the other side of the screen of the CO cable stub in the same way.
3
Starting at the cable-stub butt, wrap the pairs on one side of the screen with 2-inch, pressure sensitive,
aluminum tape. Overlay the tape by one-half its width and form the tape in place. Aluminum tape provides
electrical isolation from outside EMI sources. For these applications, dress out the splice per local practices.
4
Repeat
, wrapping the pairs on the other side of the screen in the same way.
5
Starting at the cable-stub butt of the field cable stub, wrap the pairs on one side of the screen with two layers
of
3
/
4
-inch (1.9 cm) vinyl tape. Overlap the tape by one-half its width.
6
Repeat
, wrapping the pairs on the other side of the field cable stub screen in the same way.
Maintain cable pair integrity on the HDSL and T1/G.703 sides.
If you are using blocking capacitors, signaling and dialing capability on the order wire pair will
be directional. When splicing the order wire pair, take care to maintain the direction of signaling
your application requires.
Aluminum tape may present a potential shorting hazard when splicing paper pulp insulated
cables.
The screen divider is an insulated floating divider that isolates Group 1 (blue thread sides 1 and
2 IN) from Group 2 (orange thread sides 1 and 2 OUT). Do not ground the divider or connect it
to the screen divider of the main cable. This may result in poor performance. The aluminum tape
used to wrap the input and output pairs provides the necessary isolation.
