Master Socket 5C MK4 wiring

[Rooster295]

Hello,

I have recently ently moved into a small property and have passed the EE activation date for my property. I am FTTC. 

However, I have been having issues with set up and two engineer visits to the cabinet and to make sure I set things up right have not solved anything. Personally, I believe there is a problem with the Master Socket Wiring. 

Everywhere I see talking about Master cable wires talks about blue, white orange etc. I have Red, Blue, Green and Brown. I have looked at the back and it is currently set up for Blue in A and Red in B, is this correct?

Not according to 

The nearest possibility is Pair #6.

What issues are you facing with your BB?

@Rooster295 Why would you suspect a wiring issue, with 2 engineer visit's first thing they would have done, popped the socket front off and connected to the diagnostic test point, they would have seen instantly if you had NO line connection. 

My cable was originally Orange on A, and White on B, that was how the engineer wired it probably 42 + years ago, as i have been here that time.... Can look at the cable if you wish, dead and buried now on Fibre but the cable is still hanging in the cupboard...

@Rooster295 Take the picture back off the router, and connection to your master socket, attach and post them up.

Thanks for your reply. 

The first visit was them just making sure I had set up router correctly I.e the plug was in the right section, the broadband socket was in the right bit. 

The second visit he took the faceplate off (but didn't do any sort of test) and replaced the face plate I had with a newer one. 

I do have Openreach coming but the appointment isn't until Friday and I was just anxious that if they can't do anything on Friday it will ne another week/week and a half. I have been told I am going to be compensated. 

I'll post pictures when I'm home. 

Once again, thanks for the reply.

@Rooster295 Took a quick look, the cable from pole to home, has orange/white/green/black for it, the A/B does not matter what the colours are used or even which one goes where, it does matter that 2 cores from the pole are the same used either end, and the pole goes back eventually to the green street cabinet what ever pair that OR use. With the latest equipment that is being used there is no way that you can check, so down to the engineer visit to hang a tester on your line and check out the pair all the way back to the connection point. It's not rocket science for the telecom engineers, they will have done it many many times before unless the cable is stuffed somewhere and an engineer robbed a pair to get someone else up and running, that does happen but not in your home, that's for sure....

It must matter! They are 2 separate individual landlines (even if inactive). You must pair them up, either orange/white (Pair #2) or green/black (pair #13).

Where did you get that from?

Jim's statement is correct.

Much will depend on the cable from the external junction box to the master socket. Often if installed by formal telecom trained installers it will be 6 core, but only one pair will be used, old school will follow the colour code and use blue white/white blue, but it matters not, as long as you use the same pair at both ends of the cables.

As for two lines, that really depends if there is a spare line circuit available. However not something to rely on, also depends on the cable used to connect to the house. In many cases one 6 cable is used to service more than one house.

@Mustrum I will strip a little back tomorrow and have a look see if the twisted pairs can be ID and let you know what is in that 4 core cable not in use any more.👌
