    摘要： A system for implementing multiple communication channels on a single twisted pair transmission line is disclosed. The system derives additional communication channels by way of a separate transceiver unit for each derived line. Each transceiver unit communicates in a separate predetermined frequency band. Each transceiver unit, upon connection to the transmission line, automatically utilizes the lowest unoccupied frequency band by monitoring each frequency band for the presence of signal power. Thus, as many derived lines as will be supported by the customer transmission loop can be readily added.

    摘要： A method and apparatus for qualifying a telephone transmission line for XDSL communication services is disclosed. The system includes a modem, located at the customer premises to be connected. The modem analyzes actual signals to determine the electrical characteristics of the communication channel associated with the customer premises. The modem includes a transmitter, receiver and controller to generate test signals and receive responses. The modem then analyzes the data to generate an output value indicative of the electrical characteristics of the communication channel being tested. This output value is then displayed to a user or transmitted over the communication channel to a network. The system thereby eliminates the necessity of dispatching a technician to test the telephone line, and provides more accurate test results than those achievable at the network-side of the connection alone.

    摘要： A high-speed data transmission network system (8) is provided. The system (8) includes a plurality of subscriber premises (12) that transmit a first upstream signal (28) on a first frequency band to a central office or a remote terminal (10), which is in communication with the plurality of subscriber premises (12). The central office or the remote terminal (10) broadcasts a downstream signal (30) to each of the plurality of subscriber premises (12) on a second frequency band, which is higher in frequency than said first frequency band. The downstream signal (30) contains one or more subscriber group signals and a plurality of subscriber specific signals. A controller (44) provides each of the subscriber premises (12) access to one or more of the one or more subscriber group signals and to a corresponding subscriber specific signal of the plurality of subscriber specific signals. A method of performing the same is also provided. A method of adjusting performance of transmitted signals between a central office (10) and a subscriber premise (12) within the high-speed data communication network system (8) is additionally provided.

    摘要： A method a system for automatically controlling an adaptive interleaver involves monitoring performance parameters of a transmission system and controlling the adaptive interleaver in response to the performance parameters. The SNR and the data rate of the transmission system are preferably determined. The data rate is analyzed and the adaptive interleaver is adjusted in response to the data rate and the SNR. Alternatively, the BER and the data rate of the transmission system are determined. The data rate is analyzed and the adaptive interleaver is adjusted in response to the data rate and the BER. Alternatively, any one of the SNR, BER or data rate can alone be monitored and used to the adaptive interleaver. The system provides a effective system for adjusting an adaptive interleaver in response to performance parameters of a transmission system.
