POWER LINE COMMUNICATION INTERFERENCE PROBING AND MEASUREMENT ON DIGITAL SUBSCRIBER LINES

摘要

This disclosure provides systems, methods, and apparatus for wireline communication. A digital subscriber line (DSL) receiver may detect one or more power line communication (PLC) sound packets and measure PLC signal leakage on a set of DSL lines based on the detected sound packets. For example, PLC sound packets may be transmitted by PLC devices within a PLC network, and impulse noise received on the set of DSL lines corresponding to the transmitted PLC sound packet may be detected by a DSL receiver (such as a consumer premises equipment (CPE)). The DSL receiver may measure PLC signal leakage on the set of DSL lines based on the detected PLC sound packets. In some cases, the PLC sound packets may be detected based on a duration, a position, or an arrival time of a PLC sound packet.
