  • Multimode multicarrier modem system and method of communication over the same
    Patent number: 7746923
    Abstract: An alternative approach to coping with the ever increasing demand for faster communications hardware is to design modems that are capable of operating its speeds at a higher data rate than a speed required for a single port of the standard communication rate for that modem. Basically, by utilizing a resource manager, that directs the data in and out of the various portions of the modem in an orderly manner, keeping track of which of the ports is being operated at any given point in time, a standard single port modem can be reconfigured, for example, at an over clocked rate, to manipulate the data input and output of a modem.

  • Telecommunication diagnostic information management
    Patent number: 7738633
    Abstract: A diagnostic tool is adapted to include the capability of initiating one or more diagnostic tests, collecting the raw data from the diagnostic test(s) and transporting the raw diagnostic data to an OSS. The OSS interprets the raw diagnostic data and stores the results in a database. The stored results can be searched, sorted, manipulated, analyzed, and the like. The results of any of these operations can then be, for example, displayed to one or more entities such as customer support, network operators, network planners, or the like.

  • SYSTEMS AND METHODS FOR LOOP LENGTH AND BRIDGED TAP LENGTH DETERMINATION OF A TRANSMISSION LINE
    Publication number: 20100142602
    Abstract: Through the use of a least squares minimization concept, the loop length, the number of bridged taps and length of the bridged taps on a transmission line can be determined from readily available modem data. In particular, the loop length, the number of bridge taps and the length of bridged taps can be estimated by comparing a measured frequency domain channel impulse response of the transmission line to a model of a loop that is comprised of multiple sections and multiple bridge taps.

  • COMMUNICATION CHANNEL CAPACITY ESTIMATION
    Publication number: 20100135469
    Abstract: Prediction of a channel capacity is accomplished based on a TDR echo without explicitly estimating the topology of the line. The prediction is based on obtaining a measured TDR echo, determining a theoretical TDR echo for a plurality of loop lengths, estimating the equivalent TDR length based on an optimization, updating the equivalent TDR length and utilizing the updated TDR length to predict one or more of the upstream and downstream data rates.

  • Multicarrier packet communication method
    Patent number: 7729281
    Abstract: Messages transmitted between a receiver and a transmitter are used to maximize a communication data rate. In particular, a multicarrier modulation system uses messages that are sent from the receiver to the transmitter to exchange one or more sets of optimized communication parameters. The transmitter then stores these communication parameters and when transmitting to that particular receiver, the transmitter utilizes the stored parameters in an effort to maximize the data rate to that receiver. Likewise, when the receiver receives packets from that particular transmitter, the receiver can utilize the stored communication parameters for reception.

  • Systems and Methods that Provide Frequency Domain Supplemental Training of the Time Domain Equalizer for DMT
    Publication number: 20100054321
    Abstract: Using a known or later developed time domain equalizer coefficient training algorithm, a least square solution for the time domain equalizer coefficients is taken at a starting point and iteratively improved on. In particular, the improvement is directed towards maximizing number of bits per frame loaded over the time domain equalizer coefficient choice. This can be accomplished by maximizing capacity directly rather than setting a goal to shorten the channel and hoping that the capacity will be maximized as a result.

  • PACKET RETRANSMISSION AND MEMORY SHARING
    Publication number: 20090300450
    Abstract: Through the identification of different packet-types, packets can be handled based on an assigned packet handling identifier. This identifier can, for example, enable forwarding of latency-sensitive packets without delay and allow error-sensitive packets to be stored for possible retransmission. In another embodiment, and optionally in conjunction with retransmission protocols including a packet handling identifier, a memory used for retransmission of packets can be shared with other transceiver functionality such as, coding, decoding, interleaving, deinterleaving, error correction, and the like.
