1332700	2013-03-17 20:30:00	Yeah polarity isn't supposed to matter but in practice it sometimes does. Also it needs to be the same everywhere - not swapping between jackpoints because that can cause problems too. My money is on the Blue/White, Red/Black being the lead-in from the street because it's the newest cable. My guess is 3 lead-in cables have been run in at various times in the past and the oldest 2 have been re-used to feed jackpoints and the 4th cable is a feed to the shed installed at some point. I'm probaly wrong though, guessing that nightmare from a photo is almost like picking lotto numbers.	dugimodo (138)

I guess I can just test the DSL with both polarities are see if there is any change in sync speeds/attenuation.

Blue/white red/black is going to the jackpoint for the sky decoder, sorry to disappoint. ;) I now know for a fact the feed for the shed comes from a different jackpoint in another part of the house, so it's none of those cables. I'm 99% sure I know which one is the lead-in now, but I'm still a bit mystified about the second two pair, the same colour as the lead in. Think I'll disconnect it and see if anything stops working. :p Looking forward to playing around with this actually, hopefully I don't stuff anything.	wratterus (105)

Keep an eye and an ear on the neighbours to see if anybody screams that his 'free' internet has been cut off!	coldot (6847)
