Which tool to choose for tracing SCS?

Question

Telephony

Welcome all.
In general, it is necessary to route five hundred pairs in the ATC cross. It is unrealistic to search for each pair with your hands, because the cross is old, all the pairs in the bundles stuck together. Each bundle contains 1000+ pairs.
I tried to trace pairs with Tempo PE-AT8K and Bites LY-CT025 tracers - a dead number. One yells everywhere, the other, on the contrary, does not see the right pair already 30 centimeters from the generator. Everything is aggravated by the fact that it is impossible to turn off the ATC, as a result, the voltage of 30 ... 60 V hangs on each pair (except for the traced one). So far,
I see three options for solving this problem:
Disappears, because the customer will die rather than allow the automatic telephone exchange to be turned off even at night.
2. Pull the vapors physically out of the bundles. Also disappears, because the complexity is very high, one pair takes an average of an hour. 500 pairs = 2 months of work. And a lot of "dead end" couples.
3. Find a normal tracer that can work under these conditions. By far the most viable option.
Has anyone had experience with tracers in similar conditions?
Yes, NO cable magazine.

Answer 1

It's easier for you to call with a regular multimeter. First, identify normal pairs for the presence of voltage on the cross, and then check for a short circuit.

Answer 2

If you just need tracing, then you can try Tempo CTS 132J.
If you need not tracing each pair, but sorting, then there are other devices. Google: "Identifiers and sorters of cores."
If there is no time to understand, then call the offices that have been specializing in such devices for many years: Svyazkomplekt, All Telecom and others.
