why is t1 an t3 better than cable and dsl connection?

Question

whats a t1 and a t3 connection? why are there better than dsl and cable?

Answer 1

You may have to define better.

T1 and T3 connections are reliable. They terminate at your ISP's Central Office (CO) and almost NEVER go down. Also, you get the full bandwidth. You don't share the connection with other users. If you buy a T1, you get all 1.54 Mbps of bandwidth.

Often, business will go with a T1 because they demand the reliability. This is important.

The downside of T1 and T3 is that they are expensive! I recently. I think $600.00 or more is common for a T1 line.

Cable and DSL are definitely cheaper. In some cases, they are also much faster. My Road Runner cable connection regularly shows me getting a 5Mbps download. That's equal to more than 3 T1s. But that speed is only in the down direction. They are slower going up. Cable and DSL connections are asynchronous, or different speeds in each direction. T1 and T3 are synchronous, meaning you get the full speed in both directions.

Cable connections are also shared with multiple users, so during periods of peak use, they tend to slow down. DSL doesn't have this problem (theoretically!)

So, T1 and T3 are better primarily because they are reliable.

Answer 2

A t1 is not necessarilly better, it just depends on your needs. A t1 is breaks down into 24 channels. Each channel can either be used for a phone line or 64 Kbps of Internet. A business can have 8 phone lines and 1024 Kbps of Internet (16 X 64 Kbps) over a t1 for $450. This is less expensive than paying for 8 phone lines + DSL/cable Internet making it better for them.

If you use the full t1 for Internet you will get 1.544 Mbps of bandwidth. You can get more than that with DSL or cable Internet and it's cheaper making it a better choice for home users. Your upload rate is slower with DSL and cable, but is still plenty for a home user.

A t3 is 45 Mbps of bandwidth and costs several thousand dollars a month. This makes the cost impratical for a home user, not to mention you would never get close to using that much bandwidth.

A lot of people think that t1's are just better, because back when dial-up was the only thing available for home users a t1 blew that away. They heard about a t1 and still think that it is a superior product, when that may not be the case today.

Answer 3

T1 (1.544 Mbps) and T3 (45 Mbps) connections are traditional business-class digital leased phone lines. The technology is pre-cable and pre-DSL. The main advantage is service: If either one goes down, the phone company will bend over backwards to resolve the issue as soon as possible. Business rely on these lines for their income and a downed line can cost thousands of dollars an hour. They also have time-tested monitoring and diagnostic capabilities to keep them up, so they are more reliable.

They are also different in that they don't connect directly to the Internet; they connect from one customer to another. So, for example, you could have a private line between two businesses with no Internet security hazards. Many people of course simply connect them to an ISP (whom you then have to pay an additional fee on top of what you pay Ma Bell for the T1 line).

They are symmetrical, unlike most DSL and cable lines; you get the same speed in both directions. Also important for businesses, especially those exchanging data between offices.

Like DSL lines, and unlike cable lines (which are shared), they are dedicated to one customer. Cable service is often unavailable to businesses, so that's another difference.

Not surprisingly, both are expensive, T3's absurdly so. Cost depends on distance. T1s are lower bandwidth than most cable connections and some DSL connections.

Unless you are running a business that cannot afford to go down for half a day, you are better off with cable or DSL service.

Answer 4

higher bandwidth

Answer 5

they arent neccesarily faster but they are dedicated

Answer 6

they are faster
