METHOD AND APPARATUS FOR PREDICTING SUCCESSFUL DSL LINE OPTIMIZATION
A DSL management system predicts achieving improved DSL line performance before a DSL optimizer in the DSL management system optimizes performance of the DSL line. The system obtains a current state of performance of the DSL line before optimization, and a target state of performance of the DSL line after optimization. The system further obtains a measure of the DSL line characteristics of the DSL line, and identifies, from among a plurality of records of performance information correspondingly associated with a plurality of DSL lines, a subset of the records of performance information correspondingly associated with a subset of DSL lines having a similar measure of the DSL line characteristics as the DSL line for which achieving improved DSL line performance is to be predicted. The system obtains a probability that the DSL optimizer will optimize the performance of the DSL line from the current state of performance to the target state of performance, based on a frequency with which the identified subset of records of information associated with the subset of DSL lines indicates that the DSL optimizer previously has optimized the performance of the subset of DSL lines from a same or similar state as the current state of performance to a same or similar state as the target state of performance.

Communication systems and methods for using shared channels to increase peak data rates
The present disclosure generally pertains to systems and methods for communicating data. In one exemplary embodiment, a system has a high-speed channel, such as an optical fiber, between a network facility, such as a central office (CO), and a first intermediate point between the network facility and a plurality of customer premises (CP). Digital communication links, such as DSL links, are used to carry data between the first intermediate point, such as a feeder distribution interface (FDI), and a second intermediate point, such as the Distribution Point (DP). Non-shared links may then carry the data from the second intermediate point to the CPs. The links between the two intermediate points are bonded to create a high-speed, shared data channel that permits peak data rates much greater than what would be achievable without bonding. In some embodiments, multicast data flows may be prioritized and transmitted across a set of connections to each of the intermediate points. In addition, it is possible to power components at the intermediate points from one or more of the CPs.
