T1 Connection: T1 Line
built 177 days ago
A T1 connection is a VERY FAST connection to the Internet. A T1 line is dedicated, meaning that it is always on and there are no per minute charges. You do not need to dial in. The connection is always active. With a T1 line, you can provide dozens of computers with Internet access without modems, telephone lines, and dialup accounts for each one. A T1 provides approximately 1500k of bandwidth as compared to a 28.8k modem. What this means is that 10 computers can simultaneously access the Internet and each have 150k of bandwidth (5 times what they'd have with 28.8 modems).

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.

T1 connection speed is provided in more than one ways. It can be either provided in channel format or in non channel format, as a raw stream. But in North America it is provided into channelized format alone. Each T1 line consists of 24 56/64 kbps channels. Both voice and data can be transmitted through these channels. Each channel is capable of carrying one conversation.

A t3 connection is a point-to-point dedicated line that provides 672 64-Kbps voice or data channels or in other words 28 T1 lines. A T3 is used to transmit digital signals at 44.736 megabits per second and has enough bandwidth to transmit full-motion real-time video and very large databases over a busy network. A T3 line would be installed as a major networking channel for a large corporation or university with high volume network traffic.
