Which cables do I connect?????

iMacMart · 14 Nov 2006 at 10:15

I managed to crush my BT master socket over the week (moving a desk around the room) So I brought another master socket with a built in micro filter!!

Now my issue is I have 4 cables they are Orange, Black, White and Green and according to this diagram "bottom left" I connect red to 'A' and Green to 'B' but as you can see I have no Red??

I know I only need to connect 2 cables but can anyone confirm which 2 go to a & b please?

BTW I'm colour blind but I can still understand primary colours

Many thanks in advance!!

No BT engineers about??

AFAIK, if you've smashed a Master Socket, you'll officially need to get BT around to replace it. (You can then replace the lower 'user-servicable' part with your filtered faceplate.)

However, there is some wiring information here:

Cue amazing google search

Yeah I knew that about BT but they will most likely charge me, plus I have searched Google and found all the same info..!!

Thought I may get an answer here though

Oh well call BT tomorrow I suppose

Yes, but from the first link:

The BT Drop Cable (The cable coming from the outside world)
This often has Orange, White, Green and Black wires. Usually (but not always) Orange and White are the active pair and go to connections 2 and 5. In some master boxes (such as the type with a removable front section) they go to two connectors marked A and B.

Which way around they are connected usually doesn't matter but as Rick Hughes kindly pointed out some modems (especially older USA sourced ones) and some answering machines are fussy about polarity, so it's wise if possible to check the voltage on the line and connect -48V to the B leg (J2) and 0V to the A leg (J5).
