the US had both... it just depended on who your teleco was... they way they got 
56k is/was quite simple, too... it is called "bit-robbing"... they were 
stealing one bit for every X many so they could build another connection "for 
free"... we saw this bit-robbing being done on regular POTS lines, too... some 
setups would never connect better then 9600 over their POTS lines, no matter 
how good the lines were or how good their modem was... why? bit-robbing... they 
were encoding everything in 7 bits which was redusing the max connect rate... 
that 8th bit? well, with 7 calls going, those 7 8th bits from each gave the 
telco another call path that was 7 bits wide and they got it for free...
