DSL Digital Subscriber Line is a technology for bringing high- bandwidth information to homes and small businesses over ordinary copper telephone lines. Assuming your home or small business is close enough to a telephone company central office that offers DSL service, you may be able to receive data at rates up to 6. More typically, individual connections will provide from 1. A DSL line can carry both data and voice signals and the data part of the line is continuously connected. DSL installations began in and will continue at a greatly increased pace through the next decade in a number of communities in the U. Lite that is accelerating deployment. DSL is expected to replace ISDN in many areas and to compete with the cable modem in bringing multimedia and 3-D to homes and small businesses.

Jump to navigation. The term broadband commonly refers to high-speed Internet access that is always on and faster than the traditional dial-up access. Broadband includes several high-speed transmission technologies such as:. The broadband technology you choose will depend on a number of factors. These may include whether you are located in an urban or rural area, how broadband Internet access is packaged with other services such as voice telephone and home entertainment , price, and availability.

DSL is typically used by telephone companies to offer data, video, and voice services over these existing copper telephone lines.

Learn about Digital Subscriber Line DSL , and why this high-bandwidth technology is important to the future of data delivery. DSL Digital Subscriber Line is a modem technology that uses existing telephone lines to transport high-bandwidth data, such as multimedia and video, to service subscribers. DSL provides dedicated, point-to-point, public network access. This DSL connection is typically between a network service provider NSP central office and the customer site, or on local loops created either within buildings or campuses. DSL draws significant attention from implementers and service providers. This is because it delivers high-bandwidth data rates to dispersed locations with relatively small changes to the existing telecommunications infrastructure. Asymmetric DSL allows more bandwidth for downstream than upstream data flow.

DSL digital subscriber line high-speed internet service for homes and businesses competes with cable and other types of broadband internet services. DSL delivers a broadband network using a copper phone line. The service that is best for you depends on whether you do a lot of streaming or require support for simultaneous voice and video communications. Asymmetric types of DSL connections provide more network bandwidth for downloading from the internet service provider to the subscriber's computer than for uploading in the other direction. By reducing the amount of bandwidth available upstream, service providers can offer more bandwidth downstream, which reflects the typical subscriber's needs. Symmetric DSL connections provide equal bandwidth for both uploads and downloads. Business-class DSL services tend to be symmetric because companies have greater needs for transferring data than residences do.

Digital Subscriber Line DSL, originally , digital subscriber loop is a communication medium, which is used to transfer internet through copper wire telecommunication line. DSL Internet service only works over a limited physical distance and remains unavailable in many areas where the local telephone infrastructure does not support DSL technology. The service is not available everywhere. The connection is faster for receiving data than it is for sending data over the Internet.

Fast Guide to DSL (Digital Subscriber Line)

Digital subscriber line DSL ; originally digital subscriber loop is a family of technologies that are used to transmit digital data over telephone lines. DSL service can be delivered simultaneously with wired telephone service on the same telephone line since DSL uses higher frequency bands for data. In ADSL, the data throughput in the upstream direction the direction to the service provider is lower, hence the designation of asymmetric service. In symmetric digital subscriber line SDSL services, the downstream and upstream data rates are equal. In the s, ordinary twisted-pair telephone cable often carried four megahertz MHz television signals between studios, suggesting that such lines would allow transmitting many megabits per second. It was able to give the studios a low quality cue feed but not one suitable for transmission.
