What type of master Telephone socket have you got?
The master phone socket is the main socket where the phone line enters your home, usually found in the hallway near the front door. If you can’t find it, have a look outside for any wires entering your home, then look for a white box on the wall inside.
If you have more than one socket, the master socket is the one that will feed any extension sockets. It’s always best to connect your BT Hub to the master socket if you can. This is where the broadband signal is strongest, before it goes through any other home wiring which could cause interference.
Master socket with a single socket
If your master socket has one socket, like this:
You must use a micro filter for every phone socket in your home with any phone or broadband equipment plugged in (including your Hub, phones, answer machines, digital TV boxes, and alarm systems).
A micro filter is a device that allows broadband to work at the same time as your phone service. If you need to order more micro filters from http://Telephonewiringservices.co.uk
Master socket with two sockets
If your master socket has two sockets, like this:
This means that the line is already split between your phone and broadband, so you don’t need micro filters – not for your Hub or any other devices connected to phone sockets or extensions.
You must always plug your Hub into the broadband connection on your master socket. If you plug it into a phone socket or extension, it just won’t work.
Does your master socket have a single socket with no line across the middle?
This is usually what an extension socket looks like. If all your sockets look like this, then one of them will be your master socket. It’s most likely to be the one nearest where your line comes into your home.
