DIAGNOSIS OF FAULTS AND DISTURBANCES IN FIXED ACCESS TELECOMMUNICATION NETWORKS THAT DELIVER TRIPLE-PLAY SERVICES
REZIME Faults and disturbances in the fixed access telecommunication networks made of symmetrical copper pairs through which triple-play services are delivered, are common occurrence. These faults and malfunctions can do a greater or lesser extent affect the QoS (Quality of Service) of triple-play services, especially IPTV (Internet Protocol TV) which is far most demanding service. This paper will describe some of the existing methods and tools for the detection of faults and disturbances. Also, this paper will describe some new test scenarios designed for more successful detection of faults and disturbances in order to allow higher quality of tripleplay services.
