1. A method, comprising:

  • receiving data packets on an upstream bonding group in full service mode, the upstream bonding group including a set of channels, each channel having a transmission quality;

    detecting that a select channel in the set of channels is impaired when the transmission quality of the select channel is below a threshold value;

    transitioning the receiving of the data packets from full service mode to partial service mode by disabling data grant scheduling on the select channel;

    monitoring the select channel using a spectrum management method while the receiving of the data packets is in partial service mode; and

    transitioning the receiving of the data packets from partial service mode to full service mode when a result from the spectrum management method indicates that the select channel can transmit data packets error free.
