How do you know the cable is damaged? If you have a toner you can hook the generator to the damaged pair and listen along the length of the cable to where the tone changes. It's not as fool-proof as a tester, but much cheaper.
I wanted to post a photo of my network tester but Lemmy gives me a JSON error.
Anyway, the tester is supposed to light up each strand one at a time, but what I get is disco fever.
short between pairs probably. tdr (time domain reflectometer) cable tester should help locate fault. might be pinched somewhere or something else
there are "casts" you can get to repair buried cable. usually used in copper telephone plant, i wouldn't trust it to certify to a gig but you could use it for a backup link or if you play with pots at some point. or "temporary repair"
Searched "tdr" before replying, and was inexplicably happy. :)
