T3 refers to high-speed broadband lines that are mainly used by large companies and universities, as they require faster Internet loading times due to the high volume of users on their networks. T3 allows users to download and share music, video, and other multimedia applications, which usually take a long time to download. These lines transmit data at 45 megabits per second and can be subdivided into 672 individual channels that can be leased to individual broadband subscribers. These lines consist two pairs of fiber optic cables, one for receiving data, and the other for sending data. Individual users can get the benefits of T3 by subscribing to four or five individual channels of the broadband lines that transmit data at 64 kilobits per second. Call centers and contact centers use T3 to provide twenty-four hour connectivity to their customers via multiple channels of communication such as e-mail, live chat, internet telephony, voice over internet protocol (VoIP), and Internet fax. Large companies with offices worldwide can remain connected by using T3 lines that enable uninterrupted audio and video conferencing. T3 broadband services are used in software development companies for implementing live projects over the Internet, getting instant feedbacks from the client, and incorporating any changes that might be necessary. T3 forms the backbone of Internet service providers and is used for 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 varies depending on the carrier, location of service, and the application for which it is being used. The increase in Internet traffic and the amount of data being transferred has lead to the development of newer technologies such as SONET (51.8 mbps) and Asynchronous Transfer Mode (ATM- 155 to 622 mbps) that enable even higher speeds of data transfer. These are set to replace T3 in the coming years. |
