Most of us are familiar with a normal business or residential line from the phone company. At houses or offices or somewhere where there are phone lines, a standard phone line is using on a pair of copper wires. These wires transmit people’s voices known as an analog signal. And since the end of the 20th century, many of these phone lines are used for connecting internet through modems and the lines could transmit data at around 30 kilobits per second. Hence, digital signals were then more preferable in use because they could perform faster connection and transmit bigger size 8,000 times per second at 8-bit resolution or 64 kilobits per second.
Ever since the function of the phone lines has been commonly converted its function from transmitting analog signals to digital data, almost all digital data is now transmitted through fiber optic lines, not just simple dual copper wires anymore. Companies of telephone use various designations in dealing with the capacity of fiber optic lines then they come into the use of t1 line. This line might actually come in also on copper but it could carry 24 digitized voice channels or data about 192,000 bytes per second; approximately 60 time more data to transmit than a normal residential modem. It sounds fantastic and also extremely reliable – much more reliable than an analog modem. Then the use of t1 has got wider and more people and offices have gradually modified their phone lines.
In marketing overview, business t1 has grown fast since it was invented. Then the most reliable business t1 has begun. Communication has now got better and clearer, even simpler than ever. For them who use t1 line for browsing, it is easily able to use a t1 line comfortably though there is a slight problem when several people download video files or MP3 files simultaneously at the same time. But it is not a protruding trouble, especially when the computers in use are using good Ethernet devices.
The use and business ethernet have actually gone up widely before the high demand of t1 line; however, it was dual copper wires in use that had made Ethernet and internet in slender problem for people to use it. Dual function of phone line as communication means as well as data transfer had met the users to boredom of switching the lines again and again. With the release of a single function of t1 line, they both have made a perfect couple and brought maximal performance to people.
