>> Before I used cable I had connections over BT, and they had used some sort of splitter in the road to add additional lines without having to pull new cables - can't remember the name of it now.
Are you thinking of DACS (Digital Access Carrier System)?
I thought that only affected dial up speeds, not broadband. Just prior to going over to broadband, BT went and DACS'd my phone line halving my 46k dial up speed down to approx 20k. They had to come back out and climb the pole again to remove the DACS from my line so that broadband could work on it.
EDIT - Following info taken from:-
en.wikipedia.org/wiki/Digital_Access_Carrier_System
DACS and modemsThe 56kbit/s speed of analogue modems can only be achieved if there is a single digital to analogue conversion in the route from the ISP to the end user. Since DACS involves an additional conversion to digital, and then back to analogue, this means that the maximum possible bitrate over a DACS line is 33.6 kbit/s. Furthermore, many 56kbit/s modems are unable to successfully negotiate even this speed over a DACS line. DSL broadband internet connections cannot work on a DACS line as they rely on a copper pair running all the way to the telephone exchange.
Since BT's traditional telephone line service is contractually only required to support voice and fax communication, BT are not obliged to remove a DACS because of problems with 56kbit/s modems.
