What is the box called which connects to the telephone wire when it enters the house?

Question

I need to know the name of the little box which connects to the telephone wire. I don't mean the router by the way or the microfilters. Also, what sort of connection is it that joins it to the rest of the house? Ours has a circular s***w fitting which isn't like telephone wire, could this be Cable TV?

Answer 1

A junction box

Answer 2

A network Interface box, newer models have a telephone jack in them for testing the line to determine if problems are inside the home or outside.

Answer 3

If it's a circular s***w fitting then it's probably an F connector ( http://www.satcure.co.uk/accs/page7.htm ) and is the cable connection for Virgin Media TV and telephone services.
