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： Upon detection of a trigger, such as the exceeding of an error threshold or the direction of a user, a diagnostic link system enters a diagnostic information transmission mode. This diagnostic information transmission mode allows for two modems to exchange diagnostic and/or test information that may not otherwise be exchangeable during normal communication. The diagnostic information transmission mode is initiated by transmitting an initiate diagnostic link mode message to a receiving modem accompanied by a cyclic redundancy check (CRC). The receiving modem determines, based on the CRC, if a robust communications channel is present. If a robust communications channel is present, the two modems can initiate exchange of the diagnostic and/or test information. Otherwise, the transmission power of the transmitting modem is increased and the initiate diagnostic link mode message re-transmitted to the receiving modem until the CRC is determined to be correct.
