A system and method suitable for processing television signals includes a local collection facility that has a plurality of receivers receiving a plurality of channel signals a plurality of encoders generating a first plurality of encoded signals from the plurality of channel signals, a multiplexer multiplexing the first plurality of encoded signals at a multiplexer to form first multiplexed signals, an ATM switch forming a primary ATM circuit between the local collection facility and the remote facility, and an ATM network adapter forming first ATM signals from the multiplexed signals and communicating the first ATM signals to a remote facility through the primary ATM circuit and the ATM switch. The system also includes a remote facility that includes a monitoring system generating control signals to tear down the primary ATM circuit and communicating the control signal to tear down the primary ATM circuit to the local collection facility. The ATM switch tears down the primary ATM circuit in response thereto. The multiplexer multiplexes a second plurality of encoded signals at the multiplexer to form second multiplexed signals. The ATM network adapter and the ATM switch forms a secondary ATM circuit between the local collection facility and the remote facility and forms secondary ATM signals from the second multiplexed signals. The ATM adapter communicates the secondary ATM signals to the remote facility through the secondary ATM circuit. The remote facility generates an output signal at the remote facility in response to the secondary ATM signals.
