T1 Connection
A T1 line is a high-speed physical connection capable of transmitting data at a rate of 1.5 million bps (bits per second). A T1 line represents bandwidth equal to about 24 voice telephone lines, which is usually sufficient for a small server (FTP, Web, or Audio/Video). Most Internet Service Providers will usually have multiple T1 and/or T3 lines providing service to their customers.
