A Practical implementation of high-speed communication using digital subscriber line technology

This thesis creates a plan for the practical implementation of high-speed communication for residences and businesses. By implementing low-cost, high-speed communication on a global scale, tremendous benefits can occur in areas such as Internet communication, interactive multimedia, telecommuting, and distance learning. Despite several successful trials of various high-speed communication technologies, many barriers remain before deployment can occur to the general public. This thesis proposes a plan to bridge the gap between theoretical test studies and global implementation. This thesis evaluates three communication systems as potential solutions for high-speed communication and selects one system as the solution. The three candidate systems are Digital Subscriber Line technologies (collectively referred to as xDSL), Integrated Services Digital Network (ISDN), and cable modem. The chosen technology solution, xDSL, allows twisted-pair copper wire (i.e. telephone lines) to be used for high-speed communication. The choice of xDSL as the technology solution is based on many factors, all of which correspond to practicality. The intent of this thesis is not the promotion of xDSL; rather, the primary objective is to create a plan to quickly and globally implement a low-cost, high-speed communication infrastructure for residences and businesses
