My understanding is that 56 kbps is the maximum possible
limit due to the 64 kbps digital inter-exchange channels.
(The missing 8 kbps is reserved for channel control.)
To go beyond 53 kbps up to 56 kbps requires signal power
levels on the local loop (the connection between home
and the exchange) that exceed currently allowed FCC regulations.
(The FCC is involved because the local loop
can be thought of as a transmitting antenna. They limit the
maximum power on the loop to limit the amount of interference
produced by the loop.)
The last I heard, the FCC was reviewing this law to see if the
signal power limit could be increased to allow 56 kbps.
To go beyond 56 kbps requires multiple inter-exchange channels
and that's gonna cost more. It's available in the form of ISDN
or DSL (or a T1).
Sorry, don't know anything about other than the US.
