Abstract: Systems and methods for push button configuration of devices are provided. One system comprises one or more circuits configured to determine that a configuration button on the second device has been activated and determine whether a configuration button has been activated on a first device or a third device within a time interval from a time at which the button on the second device is activated. The circuits are configured to, in response to determining that the configuration button has been activated on either the first device or the third device within the time interval, allow the second device to be authenticated. The circuits are configured to, in response to determining that the configuration button has not been activated on either the first device or the third device within the time interval, prevent admission of the second device. The network may be a wired network, such as a MoCA network.

Abstract: A communication device is configured to support communications with other devices using a physical layer (PHY)/MAC interface (PMI) protocol. For example, a first device that includes PHY component(s) may be located remotely with respect to one or more other entities that manage and control it. In one example, a second device generates (core receives from another device) a MAC message that is based on the PMI protocol and generates a PHY message based thereon. This first device and then transmits the PHY message to the first device for use by the first device to configure PHY operational parameter(s). Generally, different messages are communicated between devices based on the PMI protocol. The first device, which may generally be referred to as a remote PHY device (RPD), can be managed and controlled by one or more other devices located separately therefrom.

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 (FCU). Embodiments further include systems and methods for re-generating a data burst from OFDMA resources for transmission from the FCU to an Optical Line Terminal (OLT).

Abstract: System and methods for transmitting packets over a network are provided. A system includes a network access coordinator (NAC) configured to communicate with first and second nodes via a network backbone. The NAC is configured to coordinate access of the first and second nodes to the network backbone. The NAC is configured to receive, from the first node in a first time period, a first reservation request to transmit a first packet to the second node. The NAC is configured to allocate, in response to the first reservation request, a first slot in a second time period for the first node to transmit the first packet to the second node. The NAC is configured to allocate a second slot for the second node to transmit, to the first node, a first reply that includes an indicator of whether the second node received the first packet.
