A method to determine an access frequency band in a communication access network. The communication access network includes terminals and a head-end which includes transceivers. The head-end is downstream coupled to each one of the terminals via a downstream common link and a tree-like distributive network....http://www.google.de/patents/US6400705?utm_source=gb-gplus-sharePatent US6400705 - Method to determine an access frequency band, a head-end and a first terminal realizing such a method and a communication access network including such a head-end and such a terminal
