How HDSL worksHDSL allows public carriers and private organizations to make optimal use of one of their largest Corporate assets, the embedded Copper loop plant HDSL transforms that copper fire-the wire that heretofore was viewed as being single-voice telephone line-into high-speed digital channels capable of providing advanced service options, not only to corporations and small business, but to the home. Today, HDSL's foremost application is to provide advanced digital services to local loop customers and corporate end users.HDSL applies advanced electronics, allowing telecommunications carriers and private organizations to use existing copper transmission lines to carry fiber quality traffic without having to manipulate the wire itself. Ultimately, HDSL yields more productive service for end users and at a reduced cost, because it quadruples the distance a digital signal can travel without the need for amplification. Here's how it works A single HDSL-compatible card is attached at the central office and another card is installed al the customer premise in a telco environment or al two separate sites in a private campus area network. These systems use advanced integrated circuit designs, employing complex digital signal processing (DSP) techniques and software-based algorithms. HDSL sends signals al normal power levels. The differentiation is HDSL's singular, efficient ability to maintain or restore signal integrity in the face of coppers imperfections. HDSL creates a mathematical model of copper wire, allowing the transmission device to adroitly and precisely compensate for copper-based distortion, This adjustment happens continuously, so the transmission signal will not degrade as wire or environmental conditions change.
