Re: Old Telewest wall unit in new flat - what is it?

The box on the left is an isolator box, *may* contain a splitter instead of an isolator which means the 'fm' point may actually be a general point. The little box on the right is what we call a 77a, basically splits the outside telephone cable into internal cable. Id imagine that there was two phone lines coming off.

It looks like the cable has been cut under the TV point on the isolater point. With those brass connectors looks like it hasnt been used in a while, either that, or they used old cable!
