Determines the channel bonding strategy used by the CM upon transition to power save mode. When set to a value of disabled(-1), there will be no channel bonding response to power save mode and the device will continue to operate in the bonding mode that was in effect at the time power save was entered. When set to the default value of cmStatus(0), the CM will conform to DOCSIS 3.0 requirements by dispatching a CM-STATUS message to the CMTS indicating a transition to battery power. The CMTS is then expected to initiate a DBC which will reduce the number of channels used by the CM. The autonomous1x1 value is obsolete. If this object is set to autonomous1x1(1), then channel bonding power save will be disabled and a subsequent read of this object will return a value of disabled(-1).
