Want to find out more about T1 Line? For more information, visit us [link widoczny dla zalogowanych] on how to choose the best T1 Line for your needs.
Most T1 connections are still using copper wires but the more recent T1 lines are already switching over to fiber optics. While the optical cable are capable of speeds more than 1.544 [link widoczny dla zalogowanych] MBPS, a T1 rating still applies if the speed has not changed.
The full T1 connection is what others call a digital trunk line. The contract allows the subscriber full bandwidth of 1.544 MBPS connection for both uploading and downloading data at all times. Other flexible connection services include channelized and fractional connections.
A T1 connection is clearly designed for business use because it is very flexible. Some of the bandwidth can be assigned [link widoczny dla zalogowanych] to handle telephone calls and the rest could be reserved for internet. Because upload and download speeds are the same, a company can use an internet only T1 line to connect its server to the World Wide Web. There are other [link widoczny dla zalogowanych] connection schemes available for business. The value of T1 is that is widely implemented in the United States.
The reason why this connection has similar speeds for downloading as well as uploading is that two pairs of twisted cabling are used. One twisted wire pair downloads at 1.544 MB while the other uploads at the same rates.
A lot of reasons are behind the higher cost of a T1 connection compared to cable or DSL. One of them is the similar upload [link widoczny dla zalogowanych] and download speed of the connection at 1.544 MBPS. The main reason actually is that the connection [link widoczny dla zalogowanych] is a dedicated connection. Since regular phone lines are only in use when someone is using it for telephone calls, the line is thus shared by many subscribers. [link widoczny dla zalogowanych] Being a dedicated [link widoczny dla zalogowanych] connection implies that the line can only be used by one subscriber.
The T1 line allows both data and voice connections to be transmitted on a single line. If the main purpose of the connection is for telephony then a maximum of 24 simultaneous voice calls is allowed. [link widoczny dla zalogowanych] For data use, 1.544 megabits per second (MBPS) maximum bandwidth can be utilized. The line is clearly not intended for personal or home use. It is too [link widoczny dla zalogowanych] expensive for such an application. There are cheap but fast services that are available for domestic connections. Examples of these are DSL and broadband cable. The slower upload speed for both DSL and cable connections makes them more affordable.
The technique that is used to make T1 transmit 24 phone conversations simultaneously is called multiplexing. A very fast clock called a Stratum clock samples the digitized voice data and transmit it on its own time slice. So the 24 conversations mentioned are [link widoczny dla zalogowanych] not really occurring simultaneously. It does appear as such because the way the clock switches from one channel to the next.
The data needs of a company might not be that big to warrant a full time 1.544 MBPS bandwidth. To save on costs a scheme called burstable T1 service can be applied by the customer. The subscriber pays for a fixed rate which could be below the full bandwidth speed. When he exceeds the allocated speed, he [link widoczny dla zalogowanych] just pays extra.
