1. In a two way asymmetric network communication system that includes remote computers having respective interfaces for receiving from a server high speed downstream information conveyed over a downstream channel residing in a shared medium and for transmitting lower speed return information over an upstream channel, and wherein said asymmetric network communication system includes a network management unit located at a headend of a broadcast facility for effecting control of one of switching and routing functions in each of said downstream and upstream channels, a method of dynamically setting transmit power level of a remote interface comprising:

  • setting a transmit power level of said remote interface;

    transmitting from said remote interface at least one indication of said transmit power level; and

    repeating said steps of setting and transmitting until confirmation of a confirmed transmit power level is received by said remote interface.
