PT Telkom results on field tests of asymmetric digital subscriber line-lite technology via ATM networks

Abstract

In the competitive telecommunications market, telephone companies' success will be determined by their ability to satisfy customers with first-to-market solutions that improve efficiency, effectiveness and profits. A significant and available opportunity for telephone companies is a high-speed data access service, designed for the masses, that networks PCs together to form private networks. This service would typically include access to corporate LANs and the Internet. Using the existing network to provide these services is imperative to acquire a rapid market share. Digital subscriber line (DSL) technologies, specifically, asymmetric digital subscriber line (ADSL) products, fulfill this need. ADSL offers sufficient bandwidth to provide high-speed access to the growing number of dial-up PC users. ADSL also solves numerous network problems created by the longer-than-average holding times for data users. ADSL provides a migration path to the new network infrastructures, including asynchronous transfer mode (ATM) networks. Telephone companies must react quickly or risk losing existing market shares to the CATV companies who plan to offer high-speed access services via cable modems implemented on existing HFC networks. ADSL allows telephone companies to enter the market quickly and to offer sophisticated, high-speed data services to their customer. This paper describes the results of field tests, carried out by PT Telekomunikasi Indonesia, tbk (PT Telkom), on digital subscriber lines (xDSL) to evaluate the speed and quality of services provided by ADSL-lite technology. Following the tests, PT Telkom is preparing to launch a pilot xDSL service.
