Abstract: A method and apparatus performing fault management in an optical communications system including a polarization mode dispersion (PMD) compensator. The method and apparatus utilizes a controller receiving notifications indicative of PMD in the system, as well as at least one indicator from a system device providing an indication of an attribute of the communication system. Such system devices include a receiver providing a Q factor and a bit error rate (BER) of an optical signal, and a signal-to-noise ratio meter providing an SNR of the optical signal. The method intelligently provides fault management by correlating the PMD notifications and system indicators to distinguish between fiber failure, PMD-related degradations, and failure of monitoring equipment itself.

Abstract: A method and apparatus to verify a dialed number is described. A request is received from a calling party to send a first call station a number sent from the first call station and associated with a second call station. The number is sent in accordance with the request.

Abstract: A virtual private branch exchange (PBX) system that routes calls within a packet-switching network. Login information is received from a data device. The login information includes an alias identifying a user at the data device and a network address identifying the location of the data device on the packet-switching network. The virtual private branch exchange system associates the user's private branch exchange extension with the network address and routes calls to the user's (PBX) extension to the data device on the basis of the network address of the data device.

Abstract: A method for providing a pre-paid telephone calling card services to a calling party initiating a voice-based connection to a called party telephone using an internet-based IP Phone process running on a personal computer. The method comprises initiating an A-leg connection between the IP Phone process and an internet gateway utilizing a computer network connecting the personal computer and the internet Gateway, establishing a telephone connection between the internet gateway and a SCP. Once this connection is established, the SCP transmits a request to the calling party through the IP Phone process to provide account and call information. The calling party responds with the requested account and call information using the IP Phone process. The internet gateway then transmits the information to the SCP using DTMF tones. The SCP responds by transmitting an account query from the SCP to verify account and balance information for the calling party.

Abstract: A next generation service node (NGSN) for providing advanced interactive voice response (IVR) services within a telecommunications network. The NGSN includes intelligent peripherals implemented as network audio servers, and application servers which execute customer application files to perform IVR services. The NGSN provides reliability through redundancy of application servers, including automatic application server failover within a node, and automatic node failover between NGSNs. The NGSN features include modular software and hardware architecture with internal function encapsulation. This allows multiple vendors products to be used and provides a common signaling interface to be used to any switch network. Other NGSN features include an open systems architecture with improved scaleability and increased application processing capability.

Abstract: The present invention performs automated testing on service applications using automatically generated logs, so that new testing applications do not need to be created for each new release of a service application. The invention further provides for testing of all aspects of the service application by accounting for all data and processes performed, and does so without interfering with the processing of the service application. An Automated Regression Tester (ART) captures and records data generated by the execution of an initial version of a service application. This data is recorded to a first test log. When a new or ported version of that service application is developed, the first test log is used by the ART to generated output that emulates the operating environment, including caller and user input, of the service application. The processing of the new/ported version of the service application is captured and recorded to a second test log.

Abstract: Provided is a method and system for managing audio portions of test cases with the respective test case so that the tester (client) has access to the audio portion of test cases. Providing this functionality is particularly novel in that audio is captured within a heterogeneous client/server test environment wherein a single tester from a single client interface can test on any of a variety of test platforms. This invention allows managing audio test portions of test cases with the respective test case so that the tester (client) has access to the audio portion of test cases interactively, or at some future time. The management of the test cases is appropriately performed in the heterogeneous client/server environment. In one embodiment, the test unit(s) connected to the custom server provide an interface to perform recording of the voice path of the test case telephone call.

Abstract: A method and system for presenting in real-time a conference data set having document data, video data, and audio data, to a remote computing system of a remotely located conference participant. The system receives configuration data for the remote computing system and uses the received configuration data to select a conference data set format suitable for transmission to the remote computing system. The system encodes the conference data set in the selected conference data set format and selects an appropriate transmission web page for the encoded conference data set using the received configuration data. The system then transmits the encoded conference data set from the selected transmission web page over a public network to the remote computing system, wherein the remotely located conference participant accesses the encoded conference data set using a web browser.

Abstract: A state-of-polarization (SOP)-independent device 226, 326 and method for determining polarization mode dispersion (PMD) in an optical communication system having an optical transmission line, including a detector 244, 344 coupleable to the optical transmission line, where the detector 244, 344 is capable of analyzing a pulse shape of an optical signal on the optical transmission line to determine PMD of the optical signal. A corrector 246, 346 may be coupled to the detector 244, 344, where the corrector 246, 346 is capable of compensating the optical signal for the determined PMD. A controller 242, 342 may be coupled to the detector 244, 344 and the corrector 246, 346. The pulse shape may comprise an eye diagram, which may contain a first peak and a second peak due to PMD, where the PMD determined by the detector 244, 344 is a function of the distance between the detected first and second peaks, which is indicative of a time delay between the detected first and second peaks.

Abstract: To ensure the integrity of a telecommunications network provisioned with a distributed restoration algorithm (DRA), a communications network is provided for routing signaling messages such as DRA restoration and maintenance messages among the various nodes of the network. Thus, while data is sent among the nodes via the working links interconnecting the various nodes, signal messages are communicated among the various nodes by way of the independent communications network, which may be a wide area network. By reallocating the signal messages to a separate network, an efficient telecommunications network is effected.
