Firstly, what does ISDN and ADSL mean? And which one of them would be broadband?

Thanks :)

ASDL is the Broadband one... ISDN splits your regular line in two


ASDL (Asymmetric Digital Subscriber Line) Internet connections using DSL protocol with bandwidths from 16 to 640 Kbps upstream and 1.5 to 9 Mbps downstream.

ISDN (Integrated Services Digital Network) Special connections that use ordinary phone lines to transmit digital instead of analog signals. Briefly, ISDN is a telecommunications network that allows for digital voice, video, and data transmissions. ISDN replaces the slow and inefficient analog telephone system with a fast and efficient digital communications network. ISDN lines contain two channels: a B channel, which has a 64Kbps (kilobits per second) data transmission rate, and a D channel, which has either a 16Kbps or 64Kbps transmission rate. When the two lines are used together, transmitted data can travel at 128Kbps

Broadband is just a term which generally describes high bandwidth connections. In general broadband speeds are accepted to be from either 256kbps downstream or 512kbps downstream. There has recently been a dispute with NTL where they were branding (and probably still are) a 128kbps connection as 'broadband', which in my opinion is a load of.....
