Telephone slave extension help needed

[ronbrown]

Hi all. I'm currently trying to add a socket in an upstairs room from the master socket. At the master socket there is a 4 core cable where Orange goes to A and White goes to B and green and orange are cut back. At the slave there are 6 junctions with a 4 core cable with orange, white, blue and green. I've tried every possible connection of the colours in junction 2-5 but nothing works. On a couple of them the phone will ring continuously but none have the dial tone. Any help would be much appreciated

You need to connect to the highlighted terminals
as said previously only 2 & 5 are needed connecting 3 can cause poor broadband speed due to interference
When punching cables down onto these terminals use a proper krone tool using a screwdriver damages the terminals and yes I have found sockets wrecked by people using screwdrivers

Constant ringing is caused by connecting 2 or 5 into the 3 on one or more of the outlets. Start at the incoming line, find a and b, put them into 2 and 5, use them throughout. Only old gear needs 3, and new gear is often not polarity sensitive. Just keep it the same throughout, if the polarity is a problem, you just have to swap them at the master.
