摘要： A modem or associated computing or testing device is configured to detect the presence of one or more faults that affect DSL communications, and upon their detection, generate, for example, an indication, communication or message that recommends corrective action. In this context, a fault is generally caused by one or more unfiltered devices, impulsive noises, malfunctioning modems, or other factor that does not affect measured attenuation or measured noise, but does affect the signal-to-noise ratio (SNR) of the link. In addition to being able to generate a message guiding a user through corrective action, the system can estimate the rate impact of the detected fault.

摘要： Methods and systems for twisted pair telephone line diagnostics based on patterns of line data occurring over time. An observed data distribution is classified as periodic or based on modeled distributions previously determined to correspond to a known line activity, fault type, or fault location. A disruption or parameter value pattern is classified through statistical inference of operational and performance data collected from the line. Where the disruption and/or parameter value(s) correlate with a time the customer is at the customer premises, an inference is made that the line fault causing the disruption is more likely at the CPE than at the Central Office. Where the disruption distribution is classified as being a result of human activities initiated on the line, a fault condition associated with the activity is inferred. Where a disruption pattern is correlated with human initiated plain old telephone service (POTS), a micro-filter problem is inferred for the line.

摘要： A line test system for diagnosing and segmenting faults in a switched telephone network. The system includes a remote measurement unit installed at a switch and a test system controller. The test system controller stores data about operating parameters of each of the subscriber lines when they are believed to be free of faults. When a fault is reported, the parameters are measured again. By comparison of the measured parameters with the stored parameters, the fault can be segmented between the premise and the network. Segmentation is performed using knowledge based analysis techniques. The actual source of the fault once it is repaired is also stored by the test system controller. This historical information is used to improve the accuracy of the knowledge based analysis techniques used for segmentation.

摘要： A broadband device of the central office end capable of self-detecting and a method for detecting the XDSL port, set at least one switch matrix control switch set to connect each CO port of the XDSL to the peripheral line of the remote user’s MODEM by the switch matrix of the control switch set; the control switch set receive the control command from the control system inside the device, then disconnect any port of the CO XDSL port according to the control demand, and exchange the connected peripheral lines of any two ports among the CO XDSL ports. Disconnect any two ports of the CO XDSL ports by control switch, or exchange the connected peripheral lines of any two ports among the CO XDSL ports. Therefore, when a faulty CO port is checked out, it can be replaced by the normal port inside the un-faulty device so as to detect the initial CPE peripherally connected the faulty port, thus it can be decided whether the faulty port is caused by the port itself or by the user end. The device and method can rapidly locate and judge the port fault without additional private testing system, therefore reduces the cost.

摘要： A method and an apparatus, which generates and plays diagnostic messages (16, 18) indicative of a media terminal adaptor (10) provisioning status (28). The media terminal adaptor (10) detects errors in its provisioning status (28) or an out-of-service state (30). Thus, when a telephone (50) connected to the media terminal adaptor (10) is taken off-hook and the media terminal adaptor (10) that is not provisioned (28), or placed in an out-of-service state (30) by the service provider, the media terminal adaptor (10) will generate then an appropriate diagnostic audio voice message (16) or tone sequence (18) to the telephone (50) instructing the listener on how to proceed in order to resolve the problem (34).
