It’s a twisted 2 pair rj11 data cable. You could either make one with some ethernet crimpers and raw cat 5 or buy 2 adapters like this and use a standard ethernet cable.

Since you’re within the first 30 days there shouldn’t be a trip charge if you tell them that the other tech just put it there and hauled ass.
