A
56k line is a digital connection (possibly a leased line, possibly switched) capable of carrying 56 kilobits per second (kbps).
Note that public
telephone lines in the United States cannot carry 56 kbps, as FCC
? regulations limit the output power of modems in such a way as to limit throughput to 53 kbps, and the practical maximum over real phone lines is closer to 50 kbps.
