1. A method of forming an output signal comprising:

  • providing a plurality of primary receiving circuit modules at a local collection facility, said plurality of receiving circuit modules comprising a first receiving circuit module;

    receiving a plurality of channel signals at the local collection facility, said plurality of channel signals having a first channel signal;

    communicating the first channel signal to the first receiving circuit module to form a first encoded signal at a first encoder;

    routing the first encoded signal from the local collection facility to a multiplexer of a remote facility through a network;

    generating an output signal at the remote facility in response to the first signal;

    generating a monitoring signal from a first receiving circuit module at a monitoring system;

    communicating the monitoring signal of the first receiving circuit module to a monitoring system;

    providing a back-up receiving circuit module at the local collection facility;

    routing the first channel signal to the back-up receiving circuit module to form a second encoded signal at a second encoder;

    monitoring the second encoded signal;

    in response to the second encoded signal, routing the second encoded signal through a router at the local collection facility to the multiplexer at the remote facility; and

    forming the output signal in response to the second encoded signal.
