Abstract: This invention relates to a method of managing a digital subscriber line, where an optimum point at which to trigger a line test on the DSL line is determined. The invention continuously measures the signal to noise (SNR) margin on the DSL line, and compares the measurements to predetermined conditions based on SNR margin characteristics associated with a population of good lines. Once the SNR margin measurements fail to meet the predetermined conditions, an electrical line test is triggered. Thus, monitoring is done in the DSL domain, but the line test triggered is in the electrical domain. In an improved method, moisture level sensors provide a measure of the atmospheric moisture levels experienced by the line. If the SNR margin measurements fail to meet the predetermined conditions, and in addition there is a correlation with atmospheric moisture levels, then a line test is triggered on the line. This improvement picks up faults associated with wet joints that are generally intermittent in nature, and otherwise difficult to identify and properly test.

Abstract: This invention relates to a fault analysis device that can be connected to a DSL line and home modem, and used to perform line measurements when interference may be present. The device receives status information about the DSL line from the modem via a suitable interface such as Ethernet, and when the status information indicates that the line is not synchronised, which may be due to interference causing the line to lose synchronisation, the device disconnects the line from the modem and performs spectral analysis on the line. In doing so, measurements are made at the time when interference may be occurring, rather than at some later time when interference may no longer be present.

Abstract: This invention relates to a method of managing a digital subscriber line, where classification for a potential fault on a line is generated. The invention continuously measures the signal to noise (SNR) margin on the DSL line, and compares the measurements to predetermined conditions based on SNR margin characteristics associated with a population of good lines. Once the SNR margin measurements fail to meet the predetermined conditions, the line is flagged as experiencing a potential fault. Further measurements from weather sensors are gathered, and correlated with the SNR margin characteristics. The resulting correlation is used to generate a classification of a potential fault on the line. This can then be used to more specifically direct diagnosis and further testing.

Abstract: 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.

Abstract: The invention describes a method of performing re-synchronisations on a DSL line to optimise the synchronisation rate of the line. The line is monitored over a period of time, and a stable SNR margin is determined, below which the line is observed to lose synchronisation. Historical synchronisation rates and associated SNR margins for the line are recorded, and the highest stable synchronisation rate is determined as the historical synchronisation rate that does not have any associated SNR margins below the stable SNR margin. The method attempts to optimise the synchronisation rate of the line towards this highest stable synchronisation rate. To do this, the current target SNR margin imposed by DLM is identified, for example, by interrogating the DLM system or by noting the SNR margin on the line immediately after the most recent synchronisations. Assuming the current synchronisation rate on the line is less than the highest stable rate, then the synchronisation rate is optimised by triggering a synchronisation of the line when the SNR margin is greater than the target SNR margin plus an additional predetermined amount. The result should be an increase in the synchronisation rate, and can be repeated until the synchronisation rate reaches the highest stable synchronisation rate.

Abstract: This invention relates to a method of determining an optimum point at which to synchronise a digital subscriber line in a telecommunications network, with the aim of maximising the resulting synchronisation rate whilst maintaining a stable line. For many lines, the signal to noise ratio (SNR) varies over the course of a day, and recurs on a daily basis. The phenomenon is often referred to as the “diurnal effect”. The SNR history for the line is monitored, and the minimum SNR for the line is determined over a 24 hour period to take into account the diurnal effect. The current target SNR margin imposed by DLM on the line is determined, for example, by interrogating the DLM system or by noting the SNR margin on the line immediately after the most recent line synchronisation. The optimum point at which a resynchronisation is to be performed is calculated as point when the SNR on the line is equal to the minimum SNR plus the current target SNR margin. Synchronising when the SNR is at this point should maximise the synchronisation rate, whilst still maintaining a stable line.
