Abstract
A system for canceling crosstalk between one or more local distribution point units (DPUs)/fiber extender (FE) and a central distribution point (CDP) in a central office (CO)/cloud. The system can include a processor with memory configured to virtualize signal processing tasks from the DPU/FE, and to the CDP. The virtualization can include moving or splitting signal processing tasks such as a cross talk cancellation operation, from the DPUs/FEs and to the CDP, as virtualization of the tasks, and performing crosstalk cancelation for lines therebetween or with CPEs of a same vectored group.
