This is a data transfer system that transfers digital signals at 1.544 megabits per second (quite a bit faster than a 56K modem, which maxes out at around 0.056 Mbps). Most small to mid-sized colleges and business have T1 lines for their Internet connections. Because of the T1's large bandwidth, hundreds of people can be accessing the Internet from one T1 line. However, like all good things, too many people on one T1 line can cause dramatic decreases in data transfer speeds. For this reason, multiple T1s are often used.
