I recently did a job that involved splicing some 25 pair inside cables in a big plant. Conduits were in place and cables were run. Most splice boxes only had one cable in and one going out. A couple had a third smaller cable.

It's been quite a long time since I worked outside, but I remembered my training and used colored tie wraps to mark the direction the cables were going.

Anyone else remember this? Do you ever see it used anywhere?

We always used tags. I believe splicers used the colored ty-raps to separate the binders, etc in large pair count cables.

That's what they did up here anyway.

That's all I've ever used them for was separating the binders, never direction and I was a Bell System splicer for several years.

We used tags. If they were in a metal box (conduit) we used to write on the inside of the box with sharpies listing what came from where and was going to what.

The colored ties were actually used in outdoor pedestals in a buried plant. Since you could only see the few feet of cable in the ped before it went underground, we put colored ties to indicate which way they came from. Perhaps not quite the same as conduits inside a building, but sometimes the conduits go into the ceiling and you can't see which way they're going. At the least, you should mark the cable that feeds the splice box.

Here's the colors and directions, as I learned it with GTE:

Blue Towards the CO. Dial tone feeds in from this cable.
Orange North
Green East
Brown South
Slate West

You're also correct that we used colored ties to separate binder groups in cables, too.

In inside work, such as for 1A2 systems, we used tags. If you wanted to ensure job security, you wrote the following on the tags:

"This cable goes to the other end."

Generally, for inside work, you number or letter the cables, and make a diagram that is left, with all good intentions, somewhere safe, where subsequently, some jack-hole will lose it or throw it away. If you plan to keep working there, keep a copy for yourself.

In splicing, you wrote the cable number and pair count on the tags, and tied them to the cable choke just inside the splice case. Sometimes in a complex splice, where it wasn't obvious what cable went where, you put a tag that said "IN" or "FROM CO" and tags that said "OUT (to destination)"

I never used colored cable ties for anything other than binder identification, as the other old guys have said. In fact, we seldom used colored ties, using pigtails of wire of the proper colors instead, because plastic ties disintegrate over the years from exposure to the elements.

using pigtails of wire of the proper colors instead...

Yup, done that many times too.

Love it Arthur. Got to do it up here, especially for the uni-lingual French Bell techs.

I have found many hilarious tags over the years left by previous installers/repairmen.

Two of my favorites were

"I know where the other end of this cable is.....Do You?" :confused:
