I have a customer that has a 50 pair cable coming in from the street. A contractor accidently cut the cable. There are only three lines in use on the cable.
I thought that I coud identify the live trunks with my toner.
When I stripped back the insulation I found that the pairs were not twisted and the color code is completly different from anything I have seen.
My question is, is there an easy way to identify the live lines without stripping back each wire and going through the process of elimination?
That would take forever. Maybe some kind of tester like what electricians use for line voltage, the tester beeps when it senses voltage.
