The gateway device is connected to both the telephone network and the data network. The gateway device receives, via the telephone network, signaling information representing a telephone call from the calling party to the called party. The signaling information includes called party information. Calling party information is obtained based on the signaling information. The calling party information is provided to the called party via the data network.

Abstract: A method of training a natural language call routing system using an unsupervised trainer is provided. The unsupervised trainer is adapted to tune performance of the call routing system on the basis of feedback and new topic information.

Abstract: The present invention provides a method for determining the carrier that should be used for a particular AIN call. The following information is derived for each call: the originating calling party number, the terminating called party number, the originating LATA, the terminating LATA. Using these components, pre-defined tables are accessed that contain local calling plan information. These tables contain rate center and dial plan information that provides the local calling scope that is available to the originator of the call. Based on the information contained in the tables, the appropriate type of carrier for the call is selected and the call is routed using this carrier.

Abstract: A test method for Internet-Protocol packet networks that verifies the proper functioning of a dynamic pinhole filtering implementation as well as quantifying network vulnerability statistically, as pinholes are opened and closed is described.

Abstract: Methods and apparatus for protecting quality of service during a process involving bridge tap in a communications system are described. Bridge tap may occur during system construction, central office re-concentration, replacement projects, upgrade projects, expansion projects, and installation of back-up cables, etc. Cables, with one end connected to a point in the system, and the other end left unterminated, result in bridge tap. In the bridge tap moderator of the present invention, a plurality of termination networks are attached to a modular connector such that a separate termination load is placed across each connector terminal pair for each corresponding wire pair of the cable. Communication lines can be easily attached to the moderator thereby easily, quickly, and efficiently eliminating bridge tap on a large number of wire pairs. The bridge tap modulator apparatus and method of use also minimize the amount of time bridge tap exists during cable and/or communication device installation.

Abstract: Systems and methods for localizing the position of a wireless device using a plurality of coordinated highly directional or adaptive antennas to detect signals from the wireless device. Because of the directional nature and/or adaptive processing of the antennas, off-angle multipath signals resulting from reflection and scattering as the wireless signal propagates through a cluttered environment are rejected by the antennas and processing. As a result, the antennas pass primarily direct path signals from the wireless device to the location estimator. The time of arrival of the signal and the angle of arrival at each antenna are used to in the location estimator to calculate the position of the wireless device. Various robust inversion techniques may also be applied to the data to minimize the effect of residual multipath-corrupted detections. Furthermore, the systems and methods include specialized wireless devices that provide locating signals and signals related to the biological condition of their owner.

Abstract: A system provides secure communication of commands from a client (600) to multiple hosts (1200) via a network server (700). The system receives at least one command from the client (600), initiates one or more remote execution processes (1040) for processing the at least one command, and transmits the at least one command to one or more of the hosts (1200) via the one or more remote execution processes (1040). The system obtains, from the one or more remote execution processes (1040), data associated with the one or more hosts (1200) executing the at least one command, formats the data, and sends the formatted data to the client (600).

Abstract: Methods and systems are provided for reporting to subscribers, wireless network events in a plurality of formats and languages depending upon the particular subscriber group to which a wireless subscriber belongs. When a subscriber requests a call, a switching node in the network invokes a trigger that identifies a location register for routing the call and sends a route request to the location register. While processing the route request, if the location register detects an event that would prevent the call from being routed, the location register identifies the subscriber group of the wireless subscriber and determines a directory number associated with the identified subscriber group and the detected event. The location register then returns the determined directory number to the switching node. Using the determined directory number, the switching node establishes the call to a message node, where a message associated with the determined directory number is executed.

Abstract: A method for embedding a message within a file may include generating a session key [305] and encrypting the session key with a public key to produce an encrypted session key [310]. The message may be encrypted with the session key to produce an encrypted message [320]. A random number generator may be seeded with the public key [335], and the encrypted session key may be embedded throughout the file in locations corresponding to random numbers produced by the random number generator [340]. The random number generator may be seeded with the session key [345], and the encrypted message may be embedded throughout the file in locations corresponding to random numbers produced by the random number generator after the seeding with the session key [355].

The method includes the steps of: accessing a database including data as to a current condition of the frame; displaying, based on the accessed data, a graphical representation of the frame 275, the graphical representation including a visual indication of the current condition of the frame 275; and allowing a user to interface with the graphical representation to effect a mapping between the frame 275 and telecommunications lines leading to and from the frame 275.

Abstract: Disclosed are methods and systems for indexing or retrieving materials accessible through computer networks.

Abstract: Supporting virtual private networks by using a new layer 3 address to encapsulate a network-bound packet so that its context information, from which a layer 2 (e.g., MAC) address can be derived, is preserved. If this encapsulation was not done, the layer 2 address would change over each segment of the network. Thus, the encapsulation preserves the concept of group identification, using at least a part of the context, over the entire network and not just at the edge of the network. If a packet is received from the network (to be forwarded to a customer), the layer 3 address that was added in the encapsulation is stripped off. The original layer 3 destination address may be used with a client device addressing table to determine a new context information, and a layer 2 (e.g., MAC) address of a destination client device.

Abstract: A system and method automates the process of objectively measuring the subjective quality of packetized telecommunication signals as a function of network quality-of-service (QoS) parameters, implementation choices, and other related parameters. Computer-based simulation may be used in conjunction with objective quality measurement algorithms and pre-recorded reference or test signals. A system (300) employing this simulation method does not require the use of human subjects in subjective quality evaluation. The system and method are applicable to various types of telecommunication signals such as, for example, voice, video, audio, and multimedia.

Abstract: A speech recognition system (105) includes an acoustic front end (115) and a processing unit (125). The acoustic front end (115) receives frames of acoustic data and determines cepstral coefficients for each of the received frames. The processing unit (125) determines a number of peaks in the cepstral coefficients for each of the received frames of acoustic data and compares the peaks in the cepstral coefficients of a first one of the received frames with the peaks in the cepstral coefficients of at least a second one of the received frames. The processing unit (125) then segments the received frames of acoustic data based on the comparison.

Abstract: A data link layer switch includes a switching mechanism coupled to a plurality of port interface controllers. Each of the port interface controllers comprises a multicast address table, a multicast matcher, and a timer. The multicast address table stores multicast addresses for hosts attached to the port interface controller. The multicast matcher matches an incoming packet to a target pattern, generates a multicast address from the incoming packet if the incoming packet matches the target pattern, and stores the generated multicast address in the multicast address table. The timer determines an amount of time that the generated multicast address remains in the multicast address table.

Abstract: A system archives encryption keys used for encrypting information in a network (105). The system includes a plurality of nodes configured to collect one or more encryption keys generated at each node and to transmit the one or more collected encryption keys to a key archive (110) for storage in a database associated with the key archive (110). The key archive (110) is configured to receive encryptions keys transmitted from nodes in the network and to store the encryption keys in a database of the key archive.

Abstract: A non-lethal personal deterrent device and system. In the event of an attack by an assailant upon a victim, a device held in the hand of the victim takes a digital video and/or still image of the face of the assailant, flashes a strobe light upon the assailant, audio blasts the assailant with a warning message, obtains location information of the scene of the attack via a global positioning system (GPS), picks up audio interplay between the assailant and the victim, and transmits audio, video, and position information along with victim identification information to a receiver/processor center. The center relays the information to an operator for verification purposes which, in turn, immediately relays the information to a slam cam receptive police department thereby providing the police department with the advantage of having this information prior to responding to this emergency.

Abstract: AIN Monitor_For_Change functionality is used to implement an AIN based call retry service and an AIN based enhanced call waiting service. The AIN Monitor_For_Change functionality allows a service control point to obtain line status information, from a telephone switch. The same functionality used to provide the call retry service is combined with incoming call notification, and the collection of call disposition information from a called party, to provide the enhanced call waiting service. The enhanced call waiting service provides a called party on an existing call, incoming call notification with caller identification information. The called party is then provided the opportunity to accept the call, have the calling party wait, or send the call to voice mail. When the called party requests that the calling party wait, the calling party is notified of the called party's request and is connected to the called party once the ongoing call is completed.

Abstract: A network architecture includes a switch that can examine and selectively forward packets or frames based on information encapsulated in layer-2 information in the protocol stack. The switch segregates upstream traffic by data type and aggregates downstream Internet traffic with traffic from a local vertical services domain. The network architecture provides an efficiency way to insert vertical services.
