There are many flavours of DSL technology, but three stand out: ADSL (Asymmetric DSL), DSL Lite and HDSL (High bit-rate DSL). One possible solution to the cost issue is DSL Lite. ADSL, on the other hand, slows down to 16Kbps upstream and 2Mbps...
ADSL is more suitable for residential users and small businesses as they would mostly use it for downstream access, that's to say downloading from the internet, but having upstream speed requirements of much less than 2Mbps," Johnson explains.
OK, so we're not exactly talking gadgets, unless we stretch that term to the futuristic-looking modems both technologies rely on, but we thought it time to pit a high-speed ADSL connection against one that uses a cable modem.
ADSL theoretically provides 512Kbps downstream and 256Kbps upstream at the moment. Broadband cable providers NTL and Telewest have responded to BT's wholesale broadband cuts which should make ADSL services from BTopenworld and dozens of other ISPs...
Unlike ADSL and cable broadband, Southern Electric's product is symmetrical, with customers being promised connections of up to 1Mbps both upstream and downstream. Residential services cost £29.99 (including VAT) per month, and business services...
