My 2 BT lines current end at a master socket in the back bedroom. I was
going to call BT and ask them to move the master sockets out to my shed
(which is being converted into an office).

But having thought about it, perhaps its best just to run extensions to the
shed.

Will this affect my ADSL speed? As the OP asked, where can I get the
exterior black BT cable to run out to the shed?



Nothing is critical. BT black cable is onl useful in that it has a steel
wire running through it to help it suspend over long runs.

CAT 5 is electrically perfectly good enough.

BT engineers are all subcontarcat anyway, and no one really gives a toss
provided they have access to a master socket somewhere.

In my new house we simply picked up the old cable that had been
re-reigged into the portakabin, slung it up a ladder, stuffed it through
the eaves, and connected it via a chocolate block to some cat 5, and ran
that to the master socket. Firuntaley I still had one that says 'BT
digital access' on it.

ISDN works fine.
