Abstract
An apparatus and method for supporting enhanced ring scheduling for devices on platforms with limited power supply while seeking to preserve caller ID information and normal ringing cadence is disclosed. The ring scheduling apparatus includes a 'Line Manager' coupled to a 'Ring Scheduler'. The Line manager monitors the signaling events and determines whether the signaling commands associated with the signaling events should be modified to indicate ringing, no ringing, or pass the signaling commands unmodified. The 'Ring Scheduler' manages the available resources according to a ring cadence schedule so that the power supply of the device is not exceeded.
