As you can't see the back of this you can't see if internally is a master socket.
Does this have and a and b line? Or is this actually a standard socket and not a master?
The K422WHI is the master telephone point - this replaces the existing Master in the property. The cables in A+B will go to the terminations 2+5 respectively in the K422WHI
