The present disclosure relates generally to network diagnostics, and more specifically to techniques for determining the health of customer premises equipment (CPE) devices. In certain examples, a scoring system can determine a health score for a CPE device, the health score indicating the health of the CPE device. The health score is determined by receiving, analyzing, and integrating information from different sources, including sources in addition to CPE diagnostic data for the CPE device at the current time. Such sources can include CPE diagnostic data for the CPE device at other times, CPE diagnostic data for other CPE devices related to the CPE device (e.g., in the same household or surrounding area as the CPE device), technical specifications of the CPE device (e.g., make, model and firmware of the CPE device), or per-equalization parameters obtained by the CPE device.

Systems and methods for determining if a service interruption is associated with a placed toll-free call and if so, routing future toll-free calls to an alternative carrier route to ensure that subsequently placed toll-free calls are connected with the toll-free subscriber.

A geographically redundant inmate calling system is described. The geographically redundant inmate calling system includes two or more session border controllers that share session state information and provide for automatic failover in the event of the loss of availability of one session border controller. The geographically redundant inmate calling system eliminates any single point of failure such that communication services are highly available to inmates.

Responsive to concurrently recording on a plurality of recorders a telephonic interaction constructing a plurality of playlists, and according to faults identified while recording the plurality of playlists evaluating a quantitative quality score for each playlist in the plurality of playlists and presenting the playlists in a prioritized order according to the scores thereof.

A minimum confidence level is applied to recognize a localizable wireless system debility from a debility which is invariant from place to place or which cannot be significantly distinguished from service performance levels of comparable mobile user terminals in the network as a whole. Reports received by the population of users of a service or product family are scored, aggregated, normalized, and averaged overall and for each geographic service area. A report is received from a particular end user and the customer operated wireless instrument and transformed into an individual user experience score over a length of time and breadth of locations. The reports provided by the population of users are transformed into a population experience score that reflects usage in the same time and locations reported from the wireless instrument of the particular end user. Various potential causations are considered and those which exceed a minimum level of confidence are presented.

Methods and systems provided herein ensure that communication sessions such as phone calls over PSTNs can be reconstructed in the event that the session ends unintentionally. Methods and systems include detecting a call ended, analyzing data associated with the call, determining, based on the data, the call ended unintentionally, and reconstructing the call based on the determination the call ended unintentionally.

Various aspects described herein relate to resolving failures in digital pre-distortion (DPD) training in wireless communications. A failure during DPD training can be identified for a transceiver. One or both of a severity of the failure or a type of the failure can be determined. It can also be determined whether to perform self-recovery from the failure to continue the DPD training based at least in part on one or both of the severity of the failure or the type of the failure.

A system, computer readable medium, and method are provided for training a serial communication link to perform crosstalk cancellation. The method includes the steps of, for each crosstalk channel of one or more crosstalk channels, transmitting a training sequence over a crosstalk channel, estimating a phase offset associated with the crosstalk channel, and selecting a set of symbol response coefficients. The method further includes steps for configuring the serial communication link to perform crosstalk cancellation utilizing the selected set of symbol response coefficients and, for each crosstalk channel, updating the selected set of symbol response coefficients every number of Baud durations corresponding to the crosstalk channel.

A sequence of symbols is received on a first channel. A noise contribution of a given synchronization symbol is estimated; a reference noise contribution of at least one further symbol is estimated. Based on the noise contribution and further based on the reference noise contribution the given synchronization symbol is selectively considered when determining a coupling coefficient of crosstalk between the first channel and a second channel.
