Abstract:
1. A system, comprising: a customer premise equipment for establishing a DSL connection via a copper line, said customer premise equipment connecting to said copper line; a DSL access multiplexer, connecting to said copper line, for establishing said DSL connection with said customer premise equipment via said copper line, said DSL connection being established between said customer premise equipment and said DSL access multiplexer with a dynamic transmission rate negotiated at initialization time based on characteristics of a transmission environment during the initialization time; and a DSL connection optimizer for adaptively optimizing the transmission rate between said customer premise equipment and said DSL access multiplexer by re-initializing said DSL connection based on varying characteristics of the transmission environment; wherein said DSL connection optimizer connects to both said customer premise equipment and said DSL access multiplexer and determines to re-initialize said DSL connection based on the connection statistics stored in both said customer premise equipment and said DSL access multiplexer.
