Just my little bit of input...

It's possible to have more than one 'master' socket on one line.

In the distant past to sort out a problem with bad continuity I swapped a slave for a master as there were only 2 'good' cores on the extension cable and I didn't fancy chasing out walls to replace it - a tip I picked up from a Telewest Engineer. Its all to do with the Ringer Equivalence Number, a master socket has a REN of 1 (I think??) and a phone line will support a total REN of 4 before problems start.

Cheers
Grim
