摘要： Aspects of the present invention are directed to data communications on a wired communication network including a plurality of network branches, each having a common communication link and a plurality of network devices connected to the network branches. Communications received from the network devices during different time slots are assessed as being error-indicative or not error-indicative. Based upon the assessment, communications received during time slots within a cycle not assessed as being error-indicative are forwarded, and communications received during time slots within the cycle assessed as being error-indicative are not forwarded.

摘要： Duplex communications are facilitated. In connection with various example embodiments, current sources are used to drive transistor-based circuits coupled across a first resistive circuit, to send signals on a communications medium. While driving the transistor-based circuits, the current sources are used to drive reference transistor-based circuits coupled across a second resistive circuit. A differential output signal based upon a power-related value across the first resistive circuit, less a power-related value across the second resistive circuit. This differential output signal characterizes a power-related value corresponding to a received signal on the communications medium, as gleaned from a total signal corresponding to both transmitted and received signals, less a signal corresponding to the transmitted signal.

摘要： Data communications are effected in a network having a plurality of different network devices, at least two of the network devices connected to a common wired network link and in which each network device is assigned to communicate during different time slots within a communication cycle. Stored communication protocol data is used to evaluate received configuration data specifying a communication schedule. An output indicative of a non-compliant communication is generated if the evaluation indicates that the communication schedule fails to comply with the protocol data. If the communication schedule complies with the stored communication protocol data, the communication schedule is stored and used to communicate data between the network devices, via a central communication circuit according to time slots specified in the evaluated communication schedule.

摘要： Signal equalization is facilitated in a manner that provides for feedback operation with desirable equalization operation. As consistent with one or more embodiments, a sign is assigned to received signals by generating an output that is an absolute value of the received signals, and a comparator processes the output and to generate a signal having a voltage level limited to a predetermined value. A sign of a signal output by an equalizer is detected and used to assign a sign to the output of the comparator. A summation circuit sums the output of the equalizer with the output of the comparator, and provides the sum to the equalizer as an error signal. The equalizer modifies a frequency component of received signals based on the error signal.

摘要： 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.
