How to Identify the Master Socket
The master socket is the first socket that comes into the premises from the Telegraph pole outside.
The master socket is a white, square-shaped socket. It is made up of two parts, one over the other.
The bottom half is removable and has two screws that are equally spaced on either side of the
socket. The top half usually has a BT logo.
Note: Sometimes the master phone socket has an in-built filter, called a Service Specific Face Plate
(SSFP). In this case, the two parts of the socket will not be of equal size and are side-by-side. If you
have an SSFP, you do not need to connect a DSL filter to the master phone socket.
