T3 Lines

T3 lines refer to a type of broadband connection that transmits data at 45 megabits per second and consists of 672 individual channels, each capable of transmitting data at 64 kilobits per second, which is equivalent to a single voice grade telephone line. These lines form the backbone of Internet service providers who provide dedicated lines to large organizations with multiple users and set of two to four sub channels to individual users.

T3 lines consist of two receiving and two transmitting fiber optic cables that are capable of transmitting data at forty-five megabits per second. A single T3 connection consisting of all individual channels can cost anywhere between 4 and 15 thousand dollars depending on addition services provided with the broadband service.

The most common use of T3 lines can be found in call centers and contact centers where it is used for providing uninterrupted access to its customers via multiple channels such as voice calls, e-mail, live chat, internet telephony, voice over internet protocol (VoIP), and internet fax. These lines have helped government agencies in effectively dealing with emergency situations such as floods, hurricanes, and tornadoes by distributing the required information to those in need.

T3 lines can be used for a wide variety of applications such as T3 point-to-point, T3 Internet, T3 frame relay, T3 voice, and T3 virtual private networks (VPN). The cost of using T3 lines varies depending on the carrier, location of service, and the application for which it is being used.

Increase in Internet traffic has forced Internet service providers to develop new broadband technologies that provide even higher speeds of data transfer and uninterrupted Internet connectivity. New broadband technologies such as SONET (51.8 mbps) and Asynchronous Transfer Mode (ATM- 155 to 622 mbps) are already in the market but are very expensive and have a limited market as compared to T3 lines.
