    摘要: Systems and methods for Ethernet Passive Optical Network Over Coaxial (EPOC) power saving modes are provided. The EPOC power savings modes allow an EPOC coaxial network unit (CNU) to enter a sleep mode based on user traffic characteristics. The sleep mode may include powering down one or more module of the EPOC CNU, including radio frequency (RF) transmit/receive circuitry and associated circuitry. In embodiments, the EPOC CNU may enter sleep mode based on instructions from an optical line terminal (OLT) or based on its own determination. Embodiments further include systems and methods that allow the EPOC CNU to maintain synchronization with a servicing coaxial media converter (CMC) when it enters a sleep mode.

    摘要: Embodiments allow for EPON MAC traffic to be sub-rated according to available bandwidth and/or transmission capacity of the physical medium. EPON MAC traffic sub-rating is performed in the PHY layer. The PHY layer performing the sub-rating may be located anywhere in the communication path supporting the end-to-end EPON MAC link. Because the sub-rating is performed in the PHY layer, the EPON MAC layer at either end of the EPON MAC link is unaware of the sub-rating being performed, and thus continues to operate as it would normally according to the IEEE standard that it implements.

    摘要: Embodiments of the present invention exploit the existing capabilities of the Ethernet Passive Optical Network (EPON) MAC layer, designed for fiber optics communications, to provide a low cost MAC layer with upper layer connectivity over a hybrid fiber coaxial (HFC) network. In particular, embodiments allow for the EPON MAC to be used end-to-end (i.e., from an optical line terminal (OLT) to a coaxial network unit (CNU)) in a HFC network, thereby fully leveraging the packet processing capabilities, QoS functions, and management features of the EPON MAC. Furthermore, embodiments enable unified provisioning and management for both fiber and coaxial network units in a HFC network.

    摘要: Embodiments enable an Ethernet over Coaxial (EoC) Coaxial Media Converter (CMC) that implements only a subset of the functions (e.g., MAC and PHY) of a cable modem termination system (CMTS). The CMC sits between an optical line terminal (OLT) and a plurality of cable modems (CMs) that it serves. From the network management side at the OLT, the CMC appears and can be managed like an optical network unit (ONU). From the subscriber side, the CMC provides the same connectivity functions to the CMs as a CMTS and serves to terminate coaxial connections from the CMs.

    摘要: Embodiments enable a network operator to use any (and a single) network management system (NMS) that it desires to manage a network having mixed fiber to the home optical network units (ONUs) and coaxial connected cable modems. For example, embodiments enable a cable company operator to use a DOCSIS (Data Over Cable Service Interface Specification) NMS (which the cable company already uses to manage its DOCSIS network) to manage such mixed network, by a simple addition of a DOCSIS Mediation Layer (DML) module between the NMS and the optical line terminal (OLT). On the other hand, embodiments enable a telephone company operator to use a standard EPON (Ethernet Passive Optical Network) OLT NMS with minor OLT and OAM (Operations, Administration, and Maintenance) protocol modifications to manage the same mixed network.

    摘要: One embodiment of the present invention provides a system that facilitates dynamic allocation of upstream bandwidth in a passive optical network which includes a central node and at least one remote node. Each remote node is coupled to at least one logical entity, which corresponds to a device or a user, that transmits upstream data to the central node and receives downstream data from the central node. The central node is coupled to an external network outside of the passive optical network through a shared out-going uplink.
