    摘要： The invention relates to a method of managing a digital subscriber line, in particular for identifying the location of weather related faults. The invention continuously measures the signal to noise (SNR) margin on the DSL line as well as measurements from weather related sensors, such as moisture and wind sensors, which each have an associated geographical location. The SNR margin measures are compared to predetermined conditions based on SNR margin characteristics associated with a population of good lines. If the SNR margin measures fail to meet the predetermined conditions, the SNR measures are also compared to the weather sensor measurements over a day or number of days. If there is a correlation between the SNR margin measures and at least one of the sensors, then location of the fault is identified as the location of the sensor having the strongest correlation with the SNR measures.

    摘要： Methods and apparatus are disclosed for operating an access network including data connections (19) between end-user devices (12, 14, 16, 18) and an aggregation transceiver (20) at which connections (19) are aggregated for onward connection through the network. The method comprises, for each connection, obtaining connection data for each of a plurality of monitoring periods, each comprising shorter periods, the connection data comprising performance and user activity indications for each shorter period; monitoring the performance of the connection in order to estimate a measure of its performance during a particular monitoring period that discounts performance indications obtained in respect of shorter periods within that monitoring period when the user was inactive unless activity indications in respect of corresponding shorter periods within other monitoring periods indicate that such user inactivity is anomalous; and applying a profile to the connection that is dependent on the measure of performance of the data connection.

    摘要： A method and system for managing performance of over a multimedia content distribution network (MCDN), such as a digital subscriber line network, involves receiving an indication of an impairment in network performance from an MCDN client. The MCDN node associated with the client may be identified and a community of MCDN clients coupled to the MCDN node may be further identified Impairment information, representative of MCDN equipment, may be collected for each of the MCDN clients. Detailed network diagnostics and field service may be performed for MCDN clients based on a characterization of the impairment parameters. After remediation of the MCDN node, collection of the impairment information may be terminated.
