20120163558 | LATENCY COMPENSATION ADJUNCT FOR TELECONFERENCE VOICE SWITCHES - When making a decision about who should have control of a voice channel in a teleconference, one exemplary aspect is directed toward a voice switch mechanism that determines and takes into account a latency (such as a round trip latency) of each participant's path to the switch. The switch uses this information to ensure that short-latency paths do not have an unfair advantage over long-latency paths when individuals competitively seek control of the voice channel. Illustratively, if an individual is participating in the path that has a round trip latency of 300 ms or greater than that of other participants, the voice switch creates a level playing field even if it detects voice energy from a short-latency user first by granting control of the channel to the long-latency user if voice energy is detected from that user within 300 ms of the short-latency detection. | 06-28-2012 |

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. | 03-26-2015 |
20150349842 | FAULT IDENTIFICATION USING LINE ATTENUATIONS - The present invention presents a method of identifying faults in a DSL line using upstream and downstream attenuation measurements, which can be obtained directly from the DSLAM or CPE, thus requiring no specialist test equipment nor disrupting service. A downstream over upstream attenuation ratio is calculated for a line, with calculations repeated over a population of lines. The distribution of ratios, as well as upper and lower thresholds, is determined based on the population. A line is identified as being potentially faulty if it has an attenuation ratio above the upper threshold or below the lower threshold. Specifically, an attenuation ratio below the lower threshold is identified as having a high resistance joint fault (caused by an imperfect connection or corrosion at a joint in at least one of the pairs of a line), and a ratio above the upper threshold as a shunt (caused by degradation of the insulation between the pairs of a line, and often coupled with water ingress). | 12-03-2015 |

Nodes within the network also have a performance measure calculated based on the performance measures of the lines passing through the node. Examples of nodes include cross connection points, junction boxes, cabinets, and sections of cabling. A common faulty node is identified from all nodes along a line, based on the overall performance measures associated with those nodes. Then, all other faulty lines running through that node are identified. A distance to fault measurement is estimated for each of the identified faulty lines, using capacitance measurements for each line. A common fault location is determined based on aggregating the estimated distances to fault calculated for each of the identified faulty lines. | 11-19-2015 |
