A method and computing device for transitioning into and out of partial service mode to make bandwidth available for other resources. A trigger value is set for a channel, where a first and second cable modem have registered to use the channel, and where the first cable modem is a bonded channel modem that utilizes a bonding group that includes the channel and at least one other channel. A modulation mode for the channel is monitored. The channel is transitioned from full service mode to partial service mode when the channel is in full service mode and monitoring detects that the modulation mode is less than or equal to the trigger value. The channel is transitioned from partial service mode to full service mode when the channel is in partial service mode and the modulation mode for the channel is greater than the trigger value.
