Does anybody have an accurate imagem of wiring inside a BT mastersocket that i can use to try and sort out the mess that is my master socket in my house.

The socket has a test socket too if it makes any help.

I can't believe BT want to charge me £125 + £99 call out if its not a socket fault!
 
Well, when i moved into my house last September the phone line was knackered and after phone calls to sky BB and BT they said try the test socket - i did and it worked perfectly ..so i kept using it.

Now the time has come to fix the master socket because it's hanging off the wall and doesn't work.

This is exactly the same as my socket - what does each wire do?

Which part of the master socket are you talking about fixing?

Your perfectly ok to do anything with the faceplate, but the back part of the socket your not supposed to touch - tho BT usually want £120+ to redo one :S


You put yourself in an exposed legal position if you play with it - potentially becoming liable for anything upto and including manslaughter in a worse case scenario - so really think twice before messing with the BT side of the master socket. To cover yourself I believe BT have to maintain it within any contracted period and outside of that period I believe you are allowed to have it worked on by a fully certified electrical engineer.

The wires are explained in the link edGfaCTor posted. 1, 4 and 6 aren't used, 3 is the ring wire and 2 and 5 are the two wires that are actually used.

That picture shows the back of a faceplate though - that cable's an extension.

being an engineer myself no matter what he did with the master socket there is no way he'd get sone for manslaughter, well not unless he connected it to the mains, the most they could do is do him for is damage to said equipment, but who the hells going to tell them

i say get the wiring diagram off the net reinstall the master socket and don;t tell the robbing ****es BT

voltages used in phone equipment 0-12 v dc only

Its very unlikely - but there is the possibility of manslaughter in worse case scenarios - most likely involving feeding mains voltage into the telephone system as you say.

Your an engineer? but I guess not a BT engineer - some parts of the telephone system still use voltages well above 12v dc.

Ive rung BT today from my mates house, work in a call center i know things get recorded. i want to change to a NTE5 which the op has. Bt wanted £150 plus vat to change it over.

Correct, a standard pstn line is 50v, a dacs line 90v and an isdn line is 130v (really hurts if you get a shock from one when re-making a cable joint!!!!) Don't understand where the 12v figure comes from...
 
By and large there is little chance of any danger from coming in contact with a naked BT wire. However there are enough useless Blanks working for BT- contractors to the contractors etc and Virging/NTL or whatever they are called this week are much worse. Always check the state of the wiring using a meter if you are likely to come in to bodily contact.
It is always best to use a BT master socket and to fit a filtered master socket faceplate (XTE-2005) and to directly run a cable from there to your router - thus extracting every last drop of goodness out of your line!
If you are unable to understand the info given or indicated in this thread then get it done by BT or someone who is competent
 
yep not a bt engineer, sorry for the boob, it should be 50 v dc so im told,

like marmalade says use a meter and insulated tools Dc can give u a bit of a start if u not use to shocks lol

i am suprised about the 130v on isdn never did see any warning sighns on the kit that was installed in my mates shop

still one thing i think every one will agree with is BT are robbing gits £150 + vat to do 15 mins work, no wonder loads switch to cable
