A T1 is a digital telephone line or circuit which uses 2 dedicated pairs of copper wires. The line is capable of transmitting data simultaneously in both directions at a rate of 1.544 Megabits per second. Because of their reliability, T1 lines have been used for years to transport voice traffic and are divided into 24 channels, each capable of carrying one simultaneous voice conversation. T1 technology is extremely mature and reliable and can be used to deliver dedicated Internet, dedicated voice or a combination of voice and Internet. The cost of the T1 local loop has continued to decline. Because T1s use a line repeater technology, which amplifies the signal over long distances, T1s can be delivered at nearly any distance. Unlike DSL which is affected by the distance of the copper loop, T1s do not have this limitation and can be engineered with as many repeaters as necessary to deliver the circuit. T1s are delivered using 2 dedicated pairs of copper but may also be delivered over lon
