Abstract
Systems and methods are provided for customer premises equipment (CPE) on a passive optical network (PON). A system includes a packet processor having at least an active mode and a sleep mode, the packet processor configured to processes streams of data packets received in a data plane from an optical line terminal (OLT) through the PON when in an active mode and to enter the sleep mode when not receiving data packets in the data plane. A system further includes a micro-controller, separate from the packet processor, configured to receive from an OLT operation and management (OAM) messages that are transmitted in a control plane, and to process the OAM messages by, selectively transmitting to a central office, without waking up the packet processor, an acknowledgement message, or waking up the packet processor to receive data packets in the data plane.
