Cable TV and broadband connections

[bargepole]

Currently in the process of upgrading a flat I own. The previous owner had cable tv,(box on the wall), and also had his telephone via cable company, (copper wire from box on the wall to phone socket in the kitchen). I'm in the process of moving the phone socket from the kitchen to a bedroom which will be used as an office. What I need to know, so I can pre-wire it, is if I choose to have broadband supplied by the cable company can it be taken from the phone socket (which has been moved to the bedroom), or does the cable modem need to be supplied with a coax cable direct from the main box? Thanks

As no-one else has replied I'll try to describe my set up. The broadband cable is the same as the tv one and comes from the same junction box via a splitter. The telephone is a separate cable and comes in alone. So the answer would appear to be no, you can't take the broadband from the telephone socket in a cable system.

No you can't and they shouldn't really charge you to install extra sockets.

Hmm in the set-up I've inherited the telephone cable (copper wire) definately comes from the main cable box. So it looks like I need to run a coax cable from this main box to the bedroom/office in case I decide to have broadband via cable company(ntl). I wonder how BT can do it all in copper wire?

BT use the existing telephone cable as the broadband they supply is ADSL which piggy-backs over the standard telephony system. Cable modems are very different. We have NTL and there is a main breakout box at the front of the house. The copper telephone cable originates from this as does the coax cable for the cable TV. When I got broadband they fitted another coax cable from this main box to wherever I wanted the cable modem to be. The new cable was run outside the house to the room I designated. This was part of the installation process and the main break out box is not designed for non-NTL people to fiddle with. I am not sure whether the cable company will use a coax cable that a 3rd party (unqualified at that) had installed. Another version of cable has an ethernet port on the set top box which you use to connect to your computer. In other words the set top box is also a modem (Wightcable uses this).
