well here in Australia Telstra our national carrier only "garantees" 
2400 baud to work. I live within 2km of the exchange and the best I 
have ever achieved was 22k/sec over the lines (usually about 18k). 
This is not what the modem tells you it is doing....but what you get 
as a result of testing the ACTUAL modem speed using a line analizer 
program. What a modem manufacturer says you get and what the line 
gives you are Totaly separate.
