  • Apparatuses and methods for enabling crosstalk vectoring in expandable communication systems
    Patent number: 8605567
    Abstract: A communication system utilizes at least one digital subscriber line access multiplexer (DSLAM) at an intermediate point between a network facility and one or more customer premises. Initially, as few as one DSLAM, may be implemented at the intermediate point, but the system can be expanded to include any number of DSLAMs at the intermediate point. Any of the DSLAMs at the intermediate point can be selectively upgraded at any time to a vectoring solution as may be desired. The use of such DSLAMs provides the network service provider with flexibility in implementing and maintaining the network.
