Abstract: An example communications apparatus includes a plurality of communicatively-interconnected communication domains and an electronic switch, integrated as part of a first domain of the plurality of communicatively-interconnected communications domains. The electronic switch effects secure communications of data over the one or more channels specific to the first domain, by using a first circuit and a second circuit. The first circuit is used to obtain and process sampled channel properties associated with the one or more channels specific to the first domain. The second circuit is used to generate, in response to the first circuit, a domain-specific code that is generated pseudo-randomly using the processed sampled channel properties, the domain-specific code being used for coding data conveyed over the one or more channels specific to the first domain.

Abstract: Embodiments of a method and a device are disclosed. In an embodiment, a method for performing physical layer operations at a network node in a communications network is disclosed. In an embodiment, the method involves identifying a fault status at the network node, embedding an indication of the fault status into a bit stream at the physical layer of the network node, and transmitting the bit stream from the network node. In an embodiment, embedding an indication of the fault status into a bit stream at the physical layer includes embedding an operations, administration, and management (OAM) word into the bit stream to communicate the indication of the fault status.

Abstract: Embodiments of a method and a device are disclosed. A method for performing operations in a communications network is disclosed. The method involves, determining, at a first network node in a communications network, that a DSP of a receiver of a network node in the communications network can operate at a reduced functionality level, and communicating the determination from the first network node to a second network node in the communications network in a protocol data unit (PDU), wherein the DSP of a receiver of a network node that can operate at a reduced functionality level is a DSP of a receiver of one of the first network node and the second network node.

Abstract: The present application relates to an adaptive filter using manageable resource sharing and a method of operating the adaptive filter. The adaptive filter comprises a cluster controller configured for allocating each of several computational blocks to one of several clusters and a routing controller for configuring the routing of tapped delay signals by a routing logic to the respective cluster in accordance with an allocation of the tapped delay signals to the clusters. Each of computational blocks is configured for adjusting one filter coefficient, ci(n), in one cycle of an iterative procedure according to an adaptive convergence algorithm. The number of computational blocks is less than an order of the adaptive filter.

Abstract: An example network communication device include a communication circuit and a processing circuit. The communication circuit securely communicates over a network using a rotating code and the processing circuit enter a sleep mode at which time values of the rotating code are unknown by the network communication device. The processing circuit enters the sleep mode by requesting another network communication device of the network to authorize entering the sleep mode, and entering the sleep mode responsive to an indication verifying that the network communication device and the other network communication device agree on a set of secure parameters that is created pseudo-randomly, wherein the processing circuit enters the sleep mode with the set of secure parameters as stored for awakening but without storage of the values of the rotating key.

Abstract: A system and method for monitoring a plurality of data streams is disclosed. At a first processing stage, a first memory area is associated to an element of a plurality of data streams. Upon arrival of a frame associated with one of the plurality of data streams, a second memory area is associated to the arrived frame based on the element. In the second memory area, a data indicating an arrival of the arrived frame is recorded and on a successful recording, the frame is forwarded to a second processing stage. An independent process executes at a preselected time interval to erase contents of the first memory area.
