1. A method comprising:

  • receiving a plurality of channel signals;

    generating a first plurality of encoded signals from the plurality of channel signal at a local collection facility;

    multiplexing the first plurality of encoded signals at a multiplexer to form first multiplexed signals;

    forming a primary asynchronous transfer mode (ATM) circuit between the local collection facility and a remote facility;

    forming first ATM cells from the multiplexed signals;

    communicating the first ATM cells to the remote facility through the primary ATM circuit;

    generating control signals to tear down the primary ATM circuit at the remote facility;

    communicating the control signal to tear down the primary ATM circuit to the local collection facility;

    tearing down the primary ATM circuit;

    multiplexing a second plurality of encoded signals at the multiplexer to form second multiplexed signals;

    forming a secondary ATM circuit between the local collection facility and the remote facility;

    forming secondary ATM cells from the second multiplexed signals;

    communicating the secondary ATM cells to the remote facility through the secondary ATM circuit; and

    generating an output signal at the remote facility in response to the secondary ATM signals.
