What is the T1 line?

The

line T1 refers to a specific type of copper or optical fiber telephone line that can carry more data than traditional telephone lines. The T-Carrier line , as it is sometimes called, has been developed by AT&T Bell Labs for North America and Japan.

The twisted copper telephone lines have been standard for decades, transmitting voice and data via analog signals. Today, this standard is slowly upgraded to optical fiber lines (lines made of associated glass fibers), but most T1 lines are still made of twisted copper. The T1 line creates a "pipe" capable of blowing with larger data currents.

While standard telephone lines can transmit data and voice at about 30,000 bits per second (30 kbps) using a dial -up modem, the T1 line can transmit 1.544 megabits per second or can be used to transmit 24 digitized voice channels. Therefore can bI can use the phone service in commercial, for example, L or network data transfer and service provision up to 60 times faster than a traditional modem. Businesses with more than 8 telephone lines can save money by obtaining a reserved T1 line so that it can be heard to the place of business from the local telephone office. This can reduce telecommunications fees and ensure high -speed Internet access at the same time. Business is charged for one line T1 rather than eight (or more) separate telephone lines. Prices for the T1 line will depend on the distance of the loop or the number of mileage between Telcom and the place of business.

The cost of the T1 line may be expensive, but prices are falling with increasing demand. Internet service providers (ISP) rent T1 lines to provide their client network service. Other lines of optical fibers include T2 and T3, which can transmit up to 44.736 megabites per second. T3 line equals 28 lines T1 and is used by largerBusinesses with higher data and voicemakers. There are also more advanced T-standards, even if they are not used.

The European Union uses another, incompatible type of support line called E1 and E3. The E2 range is also available, but less common.

Generally speaking, line T1 is not cost -effective for individual or residential use. In this case, DSL or cable service is a better choice. Small businesses and government agencies - especially those that use PBX - will have the most benefit from the T1 dedicated line.
