are concerned with twenty-five pairs of wires in the splice. These
pairs of wires come from the central office on one of the fifteen hundred
pair cables and leave on the other fifteen hundred and the six hundred
pair cable. The engineer is asking us to trim off the twenty-five
pairs leaving on the fifteen hundred pair cable going to the field side
of the splice.
I have opened the lead sleeve. The lead was 3/8" to 1/2" thick. The
splice was wrapped in the original muslin and here I have cut it open to
expose the wirework. It's a twist and sleeve splice.
The splicer stripped each wire of its' insulation. He then placed
a cotton sleeve over a wire and then twisted each of the wires together
to make the connection. He then folded the connection over and slipped
the sleeve over the exposed conductor to insulate it. I don't know
the process but they would also soak paraffin into the splice. I
don't know why they did that. Maybe it acted as glue to keep the
sleeves from slipping.
is a twisted pair connection. A & C are three conductors of three
pairs twisted together. B & D are what is left of the pair I
have cut off. And what remains is the fifteen hundred and the six
hundred pairs connected. E is a cable pair.
have a photo of my trainee seated to illustrate the size of this manhole.
By the time you get Larry, the tool bucket, junk bag, two seat boxes, supplies
and my big ass in there, there isn't much room. The manhole is so
narrow and someone built a splice in front of a couple of cables that there
isn't much space to swing a hammer without bumping your elbow. What you
don't see is the ladder we used to get down there. We had to push
it up and place it on top of a splice case to get some workspace.

the wasn't room in front of the splice.
