I have been told by BT today that I have a faulty MK3 Master socket. I need to replace. I cannot source a MK 3 socket to do this so what should I do? The Mk3 has 2 portals one above the other. One for the phone line and one above for the internet. The latest Mk5 only seems to have 1 portal. Confused.
Can anyone advise please?
Get new socket with mk4 addition to give filtered socket
This is one alternative.
It fits in place of the MK3 filtered faceplate and would not involve any rewiring.
