We have two lines into our house and they come in as completely separate
2-pair cables. I would be very surprised if there were any significant
crosstalk between them, but I could be wrong. If the two services were
on separate pairs of the same 2-pair cable, I could imagine that there
_might_ be some crosstalk. But the Telstra services from the exchange
to their little wiring posts in the street carry hundreds of pairs of
wires and many of them would have ADSL services on them, I would think,
so I would be surprised if even a single 2-pair cable couldn't deal with
two simultaneous ADSL services.
