What is Fractional T1?
In the realm of data transmission, one of the big names is T1. This is a kind of transmission line that consistently delivers a high and detailed amount of data at lightning-fast speeds. A T1 line has 24 channels, each of which can transfer data at a rate of 64 kilobytes a second. Because it has 24 channels, the T1 line is commonly costly. Businesses with large amounts of data transfer taking place multiple times every day often choose to pay for a full T1 line because it is cost-effective to do so. However, another option is available. Customers can now implement a fractional T1 line, which is, as its name suggests, only part of a T1 line. A fractional T1 line allows a customer to use only a certain number of the 24 channels on a T1 line. In a sense, the customer who pays for a fractional T1 is renting the use of those channels. This kind of business decision certainly makes sense if the customer requires only a few channels, yet wants to take advantage of the speed, precision, and se
Fractional T1 is just what it sounds like. It is a portion of full T1 dedicated line service. The full T1 data rate is 1,544 K bits per second. A fractional T1 line may give you 384 K, 768 K or some other fraction of full service. Why order fractional T1 service? It saves money. Some small and medium size businesses don’t really need the bandwidth that a full T1 connection provides. What they like about T1 is that it is available in rural and less populated areas, many miles from a telephone company central office. DSL and cable modem service are often limited in coverage areas to metropolitan areas. Some telco offices aren’t even set up to provide DSL service. But, they’re all able to handle T1. It was invented by the phone companies for their own use. T1 is also available with a service level agreement, which guarantees that your data line will stay up and running. If you have experienced reliability problems with DSL broadband in your area, fractional T1 can be the next most afforda
