how many speeds can a 56 kph. modem do?

Answer 1

it can do several speeds, although the max through put is 56k actually getting that is very rare, most common usage speed is 33.6k but it can do almost any speed.

those noises that first happen are the modem communicating and negotiating with the servers modem, one of the factors negotiated is the communication speed. This starts at the fasted speed and steps down until a viable speed is reached.

Answer 3

A 56k modem can theoretically handle any speed up to 56k bits per second.
My 56k modem can work at the following speeds:
300, 1200, 2400, 7200, 9600, 12000, 14400, 16800, 19200, 21600, 24000, 26400, 28800, 29333, 30666, 32000, 33333, 36000, 37333, 38666, 40000, 41333, 42666, 44000, 45333, 46666, 48000, 49333, 50666, 52000, 53333, 54666, 56000, 57333
In practice it depends upon the modems at both ends of the link. If the modem you're trying to connect to can only handle speeds up to 32k, then that's the fastest speed the link will operate at.
Modern modems have lots of tricks to maximise throughput on bad telephone lines. They negotiate the best possible speed for each package of data transmitted or received.

Answer 4

Of course, remember that the 56kbps rating is in kiloBITS.
It's likely you'll get about 3 - 5 kiloBYTES per second.

Answer 5

everything up to 56k

not like my ethernet drive of 1 GIG

Answer 6

check on your modem settings and it will tell you all the baud rates.
