Why do companies prefer to T1 and DS3 connections to broadband?

If a company needs a bandwidth for the connection of their voice and data applications on networks that have almost always choose a T1 connection or T3. What is a T1 and a DS3 connection? Why is it better than DSL and cable for commercial use?

T1 (1.544 Mbps) and DS3 (45 Mbps), the connections are in business class traditional leased digital telephone lines. The technology is already pre-cable and DSL. The main advantage is the service: if one is not to bend the telephone companyback to resolve the problem as soon as possible. Companies rely on for their income on these lines and downed line can cost thousands of dollars per hour. You also have time-tested surveillance and diagnostic capabilities to keep them so they are more reliable.

A T1 is divided into 24 channels. Each channel can be used for a telephone line or 64 Kbps Internet. A business in Grade 8 telephone lines and 1024 kbit / s Internet (16 x 64 kbit / s) have a T1 for an average of between $ 300 - $ 500This is less expensive than paying for telephone lines 8 + Cable / DSL Internet makes it better for them.

A break in 672-channel DS3 and will cost several thousand dollars a month. However, T3 (or DS3) prices have steadily declined in recent years and can be found in rule for between $ 3-4000 in many areas. but that still makes the cost of impractical for small businesses, in many cases.

Often a corporate capacity and the cost is optimized by a plantFractional T1 or DS3 rather thsn full. The big advantage is .... cost reduction and scalability for the periods in which the Surge capacity is required, or business growth strategy is designed and built.

They are also others who are not a direct connection to the Internet, are in contact from customer to customer. So, for example, you have a line between two private companies without risk to Internet security. Many people, of course, simply connect to an ISP (which you can thenhave an extra cost) to be paid at the beginning, what you pay Ma Bell for the T1 line.

Are symmetrical, unlike the majority of DSL cable, you get the same speed in both directions. Also important for businesses, in particular the exchange of data between departments.

As DSL, and (in contrast to the cable lines) are shared, are dedicated to a customer. Cable service is for companies are often not available, so that another difference.

Not surprisingly, both canexpensive for a small company that DS3 so absurd. Costs depend mainly on the distance. This also works on it, two simple parts, the local network (the cost of fees for local historians signal the end of headquarters-user market, otherwise known as CO, at present, otherwise known as POPs, the carrier) and the port (the cost of accessing the telephone network or the Internet), through the network of the carrier. Typically, production of port access speed and price per yearCommitment will determine when the cycle is based on geography. The higher the CO and POP, plus the cost of the cycle.

Unless you run a business that can not afford to go for a half day, you are better off with cable or DSL. Otherwise .... the reliability, scalability, performance and capacity that would be better to evaluate the options using a T1 or DS3 bandwidth.
