Talk:Split pair

split pairs are transformers
Split pairs are also called slipped pairs when the problem is repeated over many pairs in a cable. In the common use, where each pair is supposed to be connected between a balanced driver and a diffferential receiver, the split pair effectively creates a transformer where changes in the output of one of the drivers of the pair will induce a signal at the input of the other receiver (or two adjacent receivers). It is not really a question of "can cause a problem", it will cause a problem if both circuits are in use. Maybe pointing out the transformer coupling will help clarify the nature of the problem. The initial baffling aspect is that everything will check out correctly under DC continuity testing. I have observed that telephone repairmen all seem to know about it. --AJim (talk) 03:32, 7 May 2015 (UTC)
