A system and method includes a first uplink signal processing circuit, a second uplink signal processing circuit and an IP network communicating the plurality of channel signals to the first uplink signal processing circuit to form a first output signal. A monitoring system monitors the first uplink signal processing circuit and generates a monitoring signal. The monitoring system redirects the channel signals to the second uplink signal processing circuit to form a second plurality of output signal signals.
