Abstract: An Ethernet passive optical network over coaxial (EPOC) system rate mechanism. A network device is provided that includes a physical layer device (PHY) that is configured for coupling to a coaxial cable, a medium independent interface that facilitates data transmission at 10 Gbit/s or greater, and a reconciliation sublayer that is coupled to the PHY via the medium independent interface. The reconciliation sublayer has a codeword detector that is configured to detect a reserved codeword that is received from the PHY over the medium independent interface. The codeword detector can be configured to forward a rate control signal to a media access control (MAC) based on the detection of the reserved codeword.

Abstract: Embodiments include systems and methods for enabling a physical layer (PHY) link signaling channel between a network termination modem and a cable modem in a cable network. The PHY link signaling channel is embedded within the same multi-carrier channel as the data and enables PHY link up between the network termination modem and cable modern without involvement of higher layers (e.g., MAC). The PHY link signaling channel can be implemented in the downstream (from the network termination modem to the cable modem(s)) or in the upstream from a cable modem to the network termination modem. Embodiments are applicable to any known cable network, and particularly to cable networks implementing the DOCSIS and EPoC standards.

Abstract: Embodiments enable a half-duplex Time Division Duplex (TDD) mode for Ethernet Passive Optical Network (EPON) or EPON over Coax (EPoC) networks. Specifically, embodiments provide systems and methods for enabling an Optical Line Terminal (OLT)/Coaxial Line Terminal (CLT) to share a physical medium spectrum in time with the Optical Network Units (ONUs)/Coaxial Network Units (CNUs) that it services. In an embodiment, the OLT/CLT includes an EPON scheduler that can schedule downstream and upstream transmissions over the same physical medium spectrum. In another embodiment, the OLT/CLT is equipped with a burst mode transmit physical layer (PHY) module, which can be controlled by an EPON Medium Access Control (MAC) module, to transmit in burst mode over the physical medium. In a further embodiment, there is provided an ONU/CNU with a burst mode receive PHY module. The burst mode receive PHY module can maintain clock timing even with non-continuous reception from the OLT/CLT.

Abstract: Embodiments include, but are not limited to, systems and methods for enabling Orthogonal Frequency Division Multiple Access (OFDMA) in the upstream in an Ethernet Passive Optical Network over Coax (EPoC) network. Embodiments include systems and methods for translating Ethernet Passive Optical Network (EPON) upstream time grants to OFDMA resources represented by individual subcarriers of an upstream OFDMA frame. In an embodiment, the translation of EPON upstream time grants to OFDMA resources ensures that Coaxial Network Units (CNUs) sharing an OFDMA frame do not use overlapping subcarriers within the frame. Embodiments further include systems and methods for timing upstream transmissions by the CNUs in order for the transmissions to be received within the same upstream OFDMA frame at a Fiber Coax Unit (ECU). Embodiments further include systems and methods for regenerating a data burst from OFDMA resources for transmission from the ECU to an Optical Line Terminal (OLT).

Abstract: Embodiments provide systems and methods for supporting the use of multiple downstream modulation profiles in an Ethernet Passive Optical Network over Coax (EPoC) network. This includes, at the Fiber Coax Unit (FCU), processing downstream traffic to determine its intended destination Coaxial Network Unit (CNU) and using a customized downstream modulation profile for the traffic based on its intended destination CNU. In addition, with the downstream modulation profile used for the downstream traffic varying in time, a downstream map indicating upcoming downstream modulation profiles in the downstream traffic is sent along with the downstream traffic from the FCU. A CNU can read the downstream map to determine upcoming downstream modulation profiles in the downstream traffic and can decide to decode a given transmitted modulation profile in the downstream traffic when the transmitted modulation profiles matches one or more downstream modulation profiles associated with the CNU.
