Phone socket wiring

[J3PTF]

So it appears I may have been a little heavy handed when taking the phone socket off to decorate the wall, and one of the wires has come out. I *think* I've guessed correctly where it came from, but just wanted to check before I seal everything back up.

Please can the resident experts check that this over?

The wire I put back is in slot 4.



Thanks

Yes 4 is where you want it.

2 and 5 are your a and b and then 3 for bell, 4 is your earth but usually only used on PBX and not domestic installs.

Perfect - thanks

This is far from perfect, a PBX is a private branch exchange, so unless you have an indian call centre in your spare room then pin 4 is not needed.

the same colour goes to the same pin, both the blues go in pin 2 and both the whites go in pin 5, all the other colours and pin numbers are immaterial, although you can keep the oranges connected to 3 if you wish, this is for the ringer circuit but is generally not needed nowadays.

The above is assuming the phone "engineer" has used the standard colours, it looks like he has.

Sadly not done by a 'phone' anything - it's in a new build so probably done by an electrician. By the state of the job they did on the aerial socket, I suspect they're not an expert on the additional stuff...
