Abstract:
1. A method for communicating via a set of frequency bands, comprising: obtaining a first electrical signal that encodes a first information stream, wherein: the energy of said first electrical signal is concentrated within a plurality of frequency bands that comprises substantially non-overlapping frequency bands; and said first information stream can be recovered from any subset of said plurality of frequency bands that is one less, in number, than said plurality of frequency bands, transmitting said first electrical signal onto a conductive path; receiving energy within a first frequency band from, said conductive path, wherein: transmitting and receiving voiceband signals within said second frequency band onto said conductive path, wherein at least part of said transmitting and receiving of voiceband signals is conducted simultaneously with said transmitting of said first electrical signal.
