Abstract: Various examples relate to a wired local area network (WLAN) including a shared transmission medium. An apparatus includes a beacon counter and an operational mode controller. The beacon counter is operably coupled to a line of a shared transmission medium of a wired local area network. The beacon counter is to count beacon signals on the line and determine a beacon count over a predetermined time period, or a beacon rate of the beacon signals. The operational mode controller is to control the apparatus to take over operation as a master node of the wired local area network based, at least in part, on a maximum bus cycle length of bus cycles on the line and responsive to the beacon count or the beacon rate.

Abstract: Synchronization for audio systems and related systems and circuitry are disclosed. An audio system includes a word select line of a digital audio interface, a serial clock line of the digital audio interface, and hardware circuitry. The hardware circuitry is configured to provide a word select signal to the word select line and a serial clock signal to the serial clock line. The word select signal is configured to indicate channels of a serial data signal provided to a serial data line of the digital audio interface. The hardware circuitry is also configured to synchronize the serial clock signal to a clock reference stream of an audio stream communicated via a network interface.

Abstract: Various embodiments relate to a wired local area network (WLAN) including a shared transmission medium (e.g., a 10SPE network). A method may include detecting an event in a WLAN including physical level collision avoidance (PLCA). The method may also include disabling a beacon of a first node operating as a master of the WLAN in response to the event. Further, the method may include enabling a second node to operate as the master of the WLAN.
