scope:
The present document defines a method to improve the coexistence by mitigating the interference between the DSL transceiver and PLT transceiver operating in overlapping frequency band but on different cables.
In-home PLT networks operate over the same spectrum as DSL networks. This increases the likelihood of crosstalk between PLT and DSL communications systems. For instance, two home networks that operate at the same frequency range, one over copper twisted-pairs (138 kHz - 30 MHz) and the other over power lines (1,8 MHz - 30 MHz ), would interfere with each other.(ETSI TR 102 930 [i.1]).
The DSL and PLT interference environment is discussed in more detail. Communication standards for PLT, have been developed with mechanisms that prevent any interference between various systems within the home environment.
