Abstract: A Data Over Cable Service Interface Specifications (DOCSIS) Passive Optical Network (PON) system (DPON) makes optical subscribers appear as cable subscribers. In one embodiment, a Cable Modem (CM) proxy is located in an Optical Line Termination (OLT). The OLT implements a cable modem protocol stack that operates as the CM proxy and communicates with a back office system. The OLT translates the data retrieved by the CM proxy into Optical Network Unit (ONU) recognizable commands, and sends the translated data to the ONU. In a second embodiment, the CM proxy is located in the ONU. The ONU implements the cable modem protocol stack that operates as the CM proxy and communicates with the back office system. The ONU translates the data retrieved by the CM proxy into ONU recognizable commands and sends the translated data to the ONU.

Abstract: In one example, an Edge Quadrature Amplitude Modulation (EQAM) communicates EQAM information to a Modular Cable Modem Termination System (M-CMTS) core using a routing protocol that is configured on a packet switched network coupling the EQAM to the M-CMTS core. The EQAM generates a routing message according to the routing protocol and inserts EQAM information, such as a description of a modulated channel extending from the EQAM, the service-group information, etc., into the routing message. The EQAM then floods the EQAM information over at least portions of a routing domain by transmitting the routing message to an adjacent intermediary device.
