Abstract
A device for managing signal transport, on a cable level, in a communication system, and a method for using same, are provided herein. The device is connectable between one or more access multiplexers (e.g., Very-high-speed Digital Subscriber Loop Access Multiplexer (VDSLAM) or a switch) and a cable in said communication system. The device includes: a plurality of access multiplexer-side transceivers connectable to access multiplexer-related physical medium, associated with said one or more access multiplexers; a plurality of customer-side transceivers connectable to respective customer-related wire pairs of said cable; and a processor connected to said access multiplexer-side transceivers and said customer-side transceivers, said processor comprising means for reducing crosstalk among said customer-related wire pairs. In some embodiments, vectoring is used for the crosstalk reduction, thus implementing a so-called cable level vectoring (CLV).
