Optimised broadband line testing

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.

Systems and methods for acquiring, accessing, and analyzing investigative information

Disclosed are systems and methods which provide availability of information on a network wide basis, with the network or information technology (IT) fabric spanning a wide range of institutions and other sources of information, including correctional facilities, without regard to which jurisdiction the source of information belongs, e.g. police, courts, federal investigation agencies, public databases etcetera. Embodiments provide an electronic based capability to identify useful information and for locating, collecting, compiling, aggregating, distilling, and/or reporting robust data.

MITIGATING CALL SETUP DISRUPTIONS
20240364810 · 2024-10-31 ·

Embodiments of the present disclosure are directed to systems and methods for mitigating disruptions to telecommunications networks. A call setup time is determined from a network perspective. If the call setup time is sufficiently long, one or more corrective actions are taken in order to identify and/or resolve a network problem that could be contributing to the long call setup time. The corrective action(s) can include comparing call setup time performance by geographic region, comparing network-observed call setup times to user equipment-observed call setup times, and/or initiating cell reselection procedures, for example.

Contact workflow testing and metrics generation

An interactive contact workflow system provides a graphical representation of a contact workflow in a graphical user interface (GUI) of an interactive contact run-time environment. The interactive contact workflow system receives a request to load response data for a previously recorded interaction with the contact workflow, retrieves the response data from a data store of stored response data, and receives a request to execute a first instruction block of the contact workflow within the interactive contact run-time environment. The interactive contact workflow system then executes the first instruction block by providing the first audio prompt of the first instruction block to an audio output interface of the client device, and provides a response from the response data to the first instruction block as a response to the first audio prompt.

Single window testing of an interactive contact workflow

An interactive contact workflow system provides a graphical representation of a contact workflow in a graphical user interface (GUI) of an interactive contact run-time environment. The interactive contact workflow system receives a request to execute a first instruction block of the contact workflow within the interactive contact run-time environment, generates a communication interface to facilitate simulated electronic communication between the GUI and the interactive contact run-time environment, and provides a first visual indicator for display within the GUI that graphically highlights the first instruction block within the GUI to indicate that the first instruction block is active. The interactive contact workflow system then executes the first instruction block by sending a first prompt of the first instruction block to the communication interface to cause the communication interface to provide the first prompt to an audio output interface.

METHOD AND DEVICE FOR DETERMINING A CORRECTIVE OPERATION FOR A DIGITAL SUBSCRIBER LINE
20180115640 · 2018-04-26 · ·

Embodiments relate to a method for determining a corrective operation for a monitored Digital Subscriber Line in a first vectoring group, executed by a monitoring device, including receiving measurement data representative of successive received signal qualities of the monitored Digital Subscriber Line at successive times, and of successive transmission activities of other Digital Subscriber Lines, wherein the other Digital Subscriber Lines include at least one first Digital Subscriber Line in said first vectoring group and at least one second Digital Subscriber Line in a second vectoring group, determining a corrective operation for the monitored Digital Subscriber Line in function of changes in the received signal qualities between times wherein the transmission activity of at least one of the other Digital Subscriber Lines changes.

Method and system for accessing call information communicated over a cellular telephone network

A method for accessing call information communicated between a source terminal and a target terminal over a carrier network is provided. The method includes receiving, at a real-time duplication server (RTDS), context information specified by a user of the source terminal that defines information to be communicated to the target terminal prior to establishment of an audio/visual call between the source terminal and target terminal. The method also includes converting, by the RTDS, the context information into a visual representation of the context information; and communicating, by the RTDS, the visual representation of the context information to a user.

Diagnostic traffic generation for automatic testing and troubleshooting

A framework in a cloud network that may allow for debugging at multiple vantage points at different layers (e.g., layer 2, layer 3, etc.). The methods may provide tracer or measurement services that filter, capture, or forward flows that may include packets, calls, or protocols to look for particular signatures.

In-service monitoring of voice quality in teleconferencing

A voice quality estimation process may be triggered by receiving one or more alarms corresponding to one or more endpoint terminals being used during a teleconference. The alarm(s) may include uplink transmission alarms, downlink transmission alarms and/or acoustic quality alarms. The alarms may be based on evaluating transmission metrics and/or acoustic quality metrics. The voice quality estimation process may require a relatively greater computational burden than the processes of evaluating the transmission metrics and/or acoustic quality metrics for the purpose of potentially triggering an alarm. The accuracy and computational complexity of voice quality estimation may be adjusted by selecting times during which alarm detection will take place, alarm detector thresholds, alarm analyzer thresholds and/or levels of voice quality estimation.

Recording detection during a communication session

A method of identifying recording of a conversation during a communication session, including establishing a communication session between a first participant and one or more remote participants, transmitting audio packets from a communication device of the first participant to the one or more remote participants, receiving audio packets from the one or more remote participants, including echo packets responsive to the transmitted audio packets, analyzing the received audio packets by an analysis application to identify delays in the echo packets relative to the transmitted packets providing an indication of the presence of a recording application at a communication device of a remote participant, notifying the communication device of the first participant.
