Some of the common "DSL Killers" are:

• Bridged taps[?]
• Load coils[?]
• "SLIC" boxes, or splitters, where copper capacity is increased by extending with multiple fibres. DSL can't travel over fibre, and most telephone companies choose not to offer fibre connections to residential customers.
• "DACS" boxes, where two baseband analog telephone lines are multiplexed over a single copper pair using ISDN-like technology to connect to the central office. Neither of the multiplexed lines is then usable for either DSL or ISDN service, as there is no metallic high-frequency path available. Where the central office connection is demultiplexed to analog connections, there is the added disadvantage that standard analog modem speeds are also reduced significantly.

As I'm not sure what its trying to say. You obviously need a continous copper line from CP to CO and I think this muddies the waters. Alex
