A test instrument connectable to a network to provide copper impairment testing and remediation in a digital subscriber line (DSL) service is provided. The test instrument may comprise a port connectable to a test point in a network. The test instrument may also comprise a processing circuit to perform tests in the following categories: (i) shorts, grounds, and opens, (ii) true length, (iii) balance, and (iv) series fault, wherein the combination of these tests may determine copper impairment. Once tests are conducted, one or more remediation recommendations may be provided based at least in part on failure in one of the test categories. The test results and remediation recommendations may then be presented at an output, such as a display at a test instrument or user device.

Systems and methods are described herein for performing automated testing of online charging systems associated with telecommunications networks. In some embodiments, the systems and methods utilize various components associated with an online charging system, such as an event mediator, to convert data associated with test cases to be simulated by the online charging system (e.g., data from spreadsheets) into various test requests actionable during the online charging system under when simulating the test cases.

The present disclosure describes a monitoring environment that monitors an activity for activity that may be indicative of being prohibited by the local, the state, and/or the national governing authorities, namely suspicious activity, or activity that is prohibited by the local, the state, and/or the national governing authorities, namely prohibited activity. The monitoring environment verifies the activity is actually being monitored within the monitoring environment. The verification can require one or more monitoring persons monitoring the activity to perform one or more tasks to verify their attentiveness in monitoring the activity. The one or more tasks can be as simple as activating a checkbox or providing a code or an electronic signature to provide some examples, although more complicated tasks, such as a biometric verification such as a retinal, a facial, and/or a voice verification to provide some examples, are possible as will be recognized by those skilled in the relevant art(s) without departing from the spirit and scope of the present disclosure.

Embodiments provide systems and methods for reconstructing a communication session upon a failure of a session manager by monitoring a communication session associated with a Universal Call IDentifier (UCID) and detecting a failure of the session manager. In some cases, A timer can be set in response to detecting the failure of the session manager. In response to the timer expiring before detecting the recovery of the session manager, the application server can end monitoring of the communication session. In response to detecting a subsequent recovery of the session manager, a re-invitation message associated with the communication session and including the UCID can be sent. Communications components of the contact center can receive and accept the re-invitation message, re-map a session initiated by the re-invitation message to the communication session based on the UCID from the re-invitation message, and reconstruct the communication session.

In accordance with embodiments disclosed herein, there are provided apparatus, systems and methods for implementing DSL line fault determination and localization via SELT, DELT, and MELT diagnostics. For example, such a system or computer implemented method may include means for: receiving Metallic Loop/Line Testing (MELT) test output from applying a MELT test to a DSL line; receiving Dual-End Line Testing (DELT) test output from applying a DELT test to the DSL line; receiving Single-Ended Loop Testing (SELT) test output from applying a SELT test to the DSL line; determining one or more faults are present on the DSL line by comparing the MELT test output, the DELT test output, and the SELT test output; and localizing the one or more determined faults by comparing the MELT test output, the DELT test output, and the SELT test output. Other related embodiments are disclosed.

Methods, systems and devices are provided to enable voice activity following a call interruption or when a call experiences or will experience interruption or diminished quality such that call experience is affected to be relayed to the communication device of the other party to the call. When an indication that an active voice call with another communication device is or will experience interruption or diminished quality such that call experience is affected, audio received from a microphone of the communication device may be recorded. A message may be generated from recorded audio and the generated message may be transmitted to the other communication device. Generation and/or transmission of the message may be performed in response to user inputs.

To improve accuracy of an evaluation in an acoustic quality evaluation test performed by comparing an evaluation target sound and a reference sound. A data correction apparatus 3 compares, in a call performed between a near-end terminal 1 and a far-end terminal 2, an evaluation target sound in which a voice output from the near-end terminal 1 is recorded and a reference sound in which a voice spoken by a call partner using the far-end terminal 2 to correct test data used in a listening test for evaluating acoustic quality of the call. A correction target determination unit 31 determines, as a correction target section, a voiced section that does not include the voice of the call partner detected from an acoustic signal representing the reference sound. A correction execution unit 32 updates the correction target section of the acoustic signal representing the reference sound with a non-voice signal predetermined.

A call path through one or more communications networks can be traced by retrieving voice equipment information based on a call data record (CDR). A path through the networks and across multiple routers may be identified based on the CDR and voice equipment information. Router operation information may be retrieved from each of the multiple routers. A filterable interface can be generated based on the CDR, voice equipment information, and router operation information through which configurations to the networks may be performed.

A method of determining the location of a disconnection on a digital subscriber line, in particular a VDSL line, where the line has a number of nodes or connection points along it. A statistical model is generated from a population of lines that maps the loop (line) lengths of each of those lines obtained by line test measurements (such as single ended line test tracesSELT traces) against the corresponding loop lengths obtained from inventory data. The model is then used to determine a predicted loop length by mapping a measured loop length (taken from line test measurements) onto an inventory loop length using the model. Knowledge of the node positions on the line is then used to give a probability a line disconnect occurring at a given node by mapping the predicted loop length onto the node positions.
