    Abstract

    Digital subscriber line (DSL) networks are currently enhanced to provide higher transmission rates and reliability in order to support emerging triple-play services, i.e., voice, video, and data. This is typically achieved by installing digital subscriber line access multiplexers (DSLAMs) in street cabinets to signi?cantly reduce the loop length to the subscribers. In addition, such DSLAMs typically employ DSL technologies that can use a wider spectrum for data transmission and thus effectively provide much higher transmission rates for short distances. The DSL performance is typically limited by crosstalk from the other lines in the bundle. Crosstalk can be mitigated by using spectrum coordination or signal coordination techniques, commonly referred to as dynamic spectrum management (DSM). This paper focuses on the concept and potential gains of signal coordination, known as DSM level 3, as well as the standardization efforts and considerations for future development and deployment of DSM level 3
