摘要： Error rate control systems, methods, and computer program products request a data rate slow-down based on the status of the error rate. A linear penalty is generated if a data rate slow-down is requested, which is then used to determine a minimum distance between constellation points in a signaling constellation or alphabet. Because the minimum distance between constellation points may be directly related to the error probability, the error rate may be controlled through the linear penalty.

摘要： Re-synchronization of sets of transmit and receive state variables in a communication system is achieved when an error is detected, without disrupting the connection. Each of first and second transceivers, connected by a communications channel, have a common set of transmit and receive state variables supporting a data encoding algorithm function. The transmitter of one of the first and second transceivers fist encodes data to be transmitted and updates the transmit state variables according to the data encoding algorithm and the receiver of the receiving transceiver validates whether or not each data block has been received correctly. During the process of decoding the data, the receive state variables are updated according to the same algorithm used to update the transmit state variables, thereby keeping the two sets of state variables in synchronism with each other. When an error is detected, re-synchronization occurs by switching to transparent mode in the direction of communication in which the error occurred and resetting the corresponding transmit and receive sets of state variables.

摘要： Broadband modems using data compression insure the physical connection between modems is solid prior to initiating error recovery procedures since its error detection runs on the compressed data. Escape sequences applicable to Transparent Mode of the Compression function enable both duplex and simplex compression functions and provide a more reliable mechanism for completion of error recovery procedures in the presence of subsequent line disturbances. Transparent Mode is used during the re-synchronization procedure. No special compression code words are required to accomplish the procedure, and there is no reduction in the number of code words available for actual compression encoding. The procedure works regardless of whether compression is being used in both directions, only one direction, or neither direction. A new Transparent Mode Command to request that the remote modem send a RESET Command is defined. The new command is termed RRESET.

摘要： Bias control systems, methods, and computer program products generate an error signal that corresponds to a difference between a reference signal and an equalizer output signal. The error signal is then filtered using a first filter circuit to generate an error signal average. If the absolute value of the error signal does not exceed a suitable threshold that is proportional to the error signal average, then the error signal is coupled to the equalizer for use in updating the filter coefficients. Furthermore, a second filter circuit may be used to generate an average of selected equalizer output signal samples. If the absolute value of the error signal is greater than the threshold that is proportional to the error signal average, then the reference signal is updated to correspond to the average of selected equalizer output signal samples. Large errors are interpreted as resulting from inaccurate reference signals or reference levels. The reference signals or reference levels may be inaccurate due to the effects of digital impairments in the network, such as RBS, exhibited in the equalizer output signal. Rather than using the error signal to update the equalizer filter coefficients, the reference signal or reference level is updated to correspond to the average of selected equalizer output signal samples. Conversely, small errors are interpreted as an indication that the reference signals or reference levels are accurate and do not require additional refinement. In this case, the error signal is used to update the equalizer filter coefficients.

摘要： Modems, methods, and computer program products for falling back to a low speed mode of operation upon detection of abnormal line conditions during startup perform a first phase of a multiphase startup procedure in accordance with a high speed mode of operation. A determination is then made whether the line conditions will support high speed communication. If a high speed connection cannot be established, then subsequent phases of the startup procedure will be performed in accordance with the low speed mode of operation. Otherwise, subsequent phases of the startup procedure will be performed in accordance with the high speed mode of operation. By detecting abnormal line conditions, such as digital discontinuity, severe attenuation, or a local loop having a non-linear frequency response, early in the startup protocol, the remainder of the startup protocol can be performed in accordance with a low speed more of operation as the detected abnormalities in the communication path will prevent the establishment of a higher data rate connection. Accordingly, the reliability and efficiency of the startup protocol are improved.

摘要： A partition that is executed by multiple processing nodes. Each node includes multiple cores and each of the cores has a frequency that can be set. A first frequency range is provided to the cores. Each core, when executing the identified partition, sets its frequency within the first frequency range. Frequency metrics are gathered from the cores running the partition by the nodes. The gathered frequency metrics are received and analyzed by a hypervisor that determines a second frequency range to use for the partition, with the second frequency range being different from the first frequency range. The second frequency range is provided to the cores at the nodes executing the identified partition. When the cores execute the identified partition, they use a frequencies within the second frequency range.

摘要： In one embodiment, a control system supports an unlimited number of feedback control loops all sharing control of a component. A component performance rate or “speed” is used as a common metric for negotiating control of the component. Each control loop continuously monitors a system parameter it is tasked with regulating, compares it to a setpoint for that system parameter, and “requests” a speed in relation to the deviation of the associated system parameter from the corresponding setpoint. A controller receives the requested speeds as dynamic inputs and selects one of the requested speeds according to predefined selection logic. The controller communicates the selected speed to an actuator, which causes the component to operate at the selected speed. In this manner, the control system in effect negotiates control of the component in a way that ensures that all of the system parameters are being managed within safe limits.
