Abstract: Embodiments of a method and a device are disclosed. In an embodiment, a method for performing physical layer operations in a communications network is disclosed. The method involves determining a desired error management mode for a receiver at a first network node, at the first network node, embedding an indication of the desired error management mode into a forward error correction (FEC) frame, and transmitting the FEC frame from the first network node. In an embodiment, embedding an indication of the desired error management mode into an FEC frame includes embedding an operations, administration, and management (OAM) word into the FEC frame to communicate the indication of the desired error management mode.

In one embodiment, a central network component for facilitating communication among communication nodes includes a bit oversampling module configured to oversample bits received from a first communication node of the communication nodes with an oversampling factor to generate oversampled bit streams, a time point selection module configured to select time points in the oversampled bit streams, where the time points correspond to inner samples of the oversampled bit streams with respect to the oversampling factor, and a bit outputting module configured to output the inner samples to a second communication node of the communication nodes between the time points. Other embodiments are also described.

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.

Abstract: Data communications are effected over one or more network branches to ensure appropriate receipt of data at different devices on the network. In accordance with an example embodiment, time-based communications are effected for a plurality of different network devices, at least two of which are connected to a common wired network link, with each network device being assigned to communicate during different time slots within a communication cycle. Each communication received on the common wired network link is assessed as being error-indicative or not error-indicative. In response to a received communication on the common wired network link being assessed as being error-indicative, the common wired network link is operated to corrupt data received on the branch, such as by driving the branch during a time slot in which the error-indicative communication is received, therein ensuring that other network devices disregard the data received during that time slot.

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: Various embodiments relate to a device for reducing noise in a received signal, the device including a memory; a processor configured to: receive a signal containing narrow band noise which was transmitted over a channel and received at an analog front end; add two separate delays to the signal to generate a first delayed signal and a second delayed signal; apply an adaptive noise cancellation using the first delayed signal and the second delayed signal to estimate the narrow band noise; and remove the narrow band noise based upon the estimated narrow band noise.
