Abstract:
1. A method comprising: optimizing downstream power backoff (DPBO) parameters of a plurality of cabinet-deployed digital subscriber lines (DSLs) based on crosstalk coupling parameters among the cabinet-deployed DSLs, wherein the DPBO parameters include a plurality of cutoff frequencies, each of which corresponds to one of the plurality of DSLs, and wherein optimizing the DPBO parameters comprises: for each line n, where n equals 1 to N, where N is a total number of the plurality of DSLs: DPBOFMAX for each line i, where i equals 1 to N, iteratively repeating the following steps until DPBOFMAX determining the cutoff frequency of the PSD profile as a final intermediate cutoff frequency produced by the iterative steps.
