Abstract: Embodiments of a method and a device are disclosed. In an embodiment, a method for operating a communications network is disclosed. The method involves setting, at a first network node in the communications network, a register value that is indicative of a fault status associated with the first network node, the register value being set in a physical layer device of the first network node, receiving fault status information at an element in the communications network, the fault status information corresponding to the register value that is set in the physical layer device of the first network node, and determining, at the element in the communications network, a fault status of the communications network in response to the fault status information received at the element in the communications network.

Abstract: A method and apparatus for updating an encryption key for performing encrypted communication over a communications network. The method comprises, within a timestamp distribution node, transmitting a message to at least one timestamp reception node of the communications network containing a timestamp value. The method further comprises, within the at least one timestamp reception node, receiving the message from the timestamp distribution node and extracting the timestamp value. Wherein, within each of the timestamp distribution node and the at least one timestamp reception node, the method comprises generating at least one updated encryption key for performing encrypted communication based at least partly on the extracted timestamp value.

Abstract: A transceiver, TX/RX PHY, arranged for bi-directional data communication of a node with a counterpart node connected to a point-to-point network using differential mode signaling over a single twisted-pair cable is disclosed. The transceiver, TX/RX PHY, includes a common mode choke arranged between of the TX/RX PHY and the single twisted-pair cable and provided for common mode current suppression. Further included is a switching arrangement arranged between the TX/RX PHY, the common mode choke and the single twisted-pair cable and configured to switchably change a polarity of one of the windings of the common mode choke. A detection section is included and coupled via the switching arrangement to the common mode choke and configured to detect a common mode signal on the single twisted-pair cable in response to a transmission of a test signal by the counterpart node.

Abstract: Embodiments of a method and a device are disclosed. In an embodiment, a method for performing physical layer operations in a point-to-point network is disclosed. The method involves receiving, from a link in the communications network, information in an operations, administration, and management (OAM) word, setting an interleaving level, L, in response to the information received in the OAM word, inserting an OAM word into a forward error correction (FEC) frame, the OAM word including the set interleaving level (L), and transmitting, onto the link in the communications network, the FEC frame, which includes the OAM word.

Abstract: The present application relates to an adaptive filter using resource sharing and a method of operating the adaptive filter. The filter comprises at least one computational block, a monitoring block and an offset calculation block. The computational block is configured for adjusting a filter coefficient, ci(n), in an iterative procedure according to an adaptive convergence algorithm. The monitoring block is configured for monitoring the development of the determined filter coefficient, ci(n), during the performing of the iterative procedure. The offset calculation block is configured for determining an offset, Offi, based on a monitored change of the filter coefficient, ci(n), each first time period, T1, and for outputting the determined offset, Offi, to the computational block if the determined filter coefficient, ci(n), has not reached the steady state. The computational block is configured to accept the determined offset, Offi, and to inject the determined offset, Offi, into the iterative procedure.

Abstract: The present application relates to a baseband communications transceiver and a method of operating the baseband communications transceiver. The transceiver comprises an analog front end transmitter section, AFE TX, with a digital to analog converter, DAC, and a transmission, TX, driver; an analog front end receiver section, AFE RX, with an analog-to-digital converter, ADC; at least one equalizer arranged downstream of the AFE RX and implemented on the basis of an adaptive filter; at least one loss encode and a channel monitoring block. The at least one loss encode is configured to determine loss value data indicative of a signal loss on the communication channel based on filter coefficients of the adaptive filter. The channel monitoring block is configured to determine an amplitude control signal, which is provided to control the amplitude of analog signals generated by the TX driver of the AFE TX.
