/diy/ - Do It Yourself

>>1559858
Every combination isnt necessary, the resistance from one pair to another is usually okay, or at least not part of this testing.

I work for the phone company and they explicitly sold or trashed all of these pair tagging units 15 years ago so they would be less competitive with the cable and cellphone companies.

It would make my work so much easier I wonder how cheaply I could diy it. This is like 2000$ used, 5000$ new

Its main purpose is to make identifying pairs very quick. You clip on in the splice with another unit and it communicates back what pair, 1-100 you clipped on so then you can put it on the right connector.
