Essay/term paper: modems essay, term paper, research paper: information technology cable modem (t-1) 1 600 000 bps (both ways) speeds of roughly 128,000 bits-per-second over regular phone lines isdn has a couple of advantages it uses the same pair wire found in regular phone lines.
A cable modem is a digital modem that sends and receives digital data over the cable television (catv) network (figure 8-18) with more than 110 million homes wired for cable television, cable modems provide a faster internet access alternative to dial-up for the home user and have speeds similar to dsl.
