摘要： Example registration procedures for Ethernet Passive Optical Network Over Coax (EPOC) are provided. The procedures are compliant with the Ethernet Passive Optical Network (EPON) standard. The procedures cover initial coaxial media converter (CMC) registration; physical layer discovery and link up over a coaxial link of an EPOC network; and medium access control (MAC)-level discovery and link up over an EPOC network. As such, the procedures can he used to fully bring air EPOC network to user traffic readiness. In addition, the procedures, or a variation thereof, can be used to enable periodic maintenance of the coaxial link of the EPOC network, thereby maintaining adequate communication conditions over the coaxial link.

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： 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： One embodiment provides a system that tests optical performance in an Ethernet passive optical network (EPON), which includes an optical line terminal (OLT) and at least one optical network unit (ONU). The system configures an ONU with a circular queue that contains test frames for testing optical performance. The OLT then notifies the ONU to transmit test frames at a specified data rate for a specified duration. After receiving test frames at the OLT, the system measures frame loss and/or bit error rate based on the received test frames.

摘要： One embodiment provides a system that performs protection switching in an Ethernet passive optical network (EPON), which includes an optical line terminal (OLT) and at least one optical network unit (ONU). The system is configured with at least one redundant component for the OLT and/or ONUs, wherein the redundant component can be optical or electrical, and can be a port, line card or link. The system provides protection by detecting a failure, and switching automatically to the redundant components to reduce service disruption time. The protection switching comprises: preserving the existing configuration over the loss of at least one of a multiple-point control protocol (MPCP) message; an operations, administration and maintenance (OAM) message; and a signal on the physical layer. The system recovers from the failure without performing ONU discovery.

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.
