Abstract: A system and method for routing administrative data over a telecommunications network to a remote processor establishes a connection between a router and the remote processor over a primary link. A processor associated with the router is adapted to detect a predetermined condition and thereupon to automatically reconfigure the router to establish another connection with the remote processor or a connection with another remote processor. The data may be routed over a telecommunications switching network using a router having inverse multiplexing capability. Further, a sockets connection may be established between the associated processor and the remote processor for monitoring the status of the connection between the router and the remote processor to detect a predetermined condition such as a link failure. External customer data may be routed to the system for remote archival purposes.

Abstract: The invention provides a system for measuring the synchronization of SONET signals. The invention counts the bits in an STS-1 signal starting at a reference time point and ending when the framing bytes A1 and A2 are detected. The counts are repeated every other SONET frame. The system can be applied to multiple SONET signals arriving at a location. The system can employ a CPU to analyze the bit counts to determine if the timing of a SONET signal begins to experience wander.

Abstract: A data access client program resides on a local computer and a data access server program resides on a remote computer. The programs are adapted to enable an application program on the local computer to access data stored on the remote computer. The client and server programs are adapted to communicate with one another over a communication link, preferably one employing the Advanced Program to Program Communication (APPC) protocol. The user stores the attributes of remote files to be accessed on a predetermined computer. When the application program on the local computer issues a remote data access request, the data access client program communicates the request to the data access server program. The server is configured to obtain the previously stored file attributes and to access the data requested by the application program based thereon. The server returns the requested information to the client, which in turn provides the information to the application program.

Abstract: The present invention is a SONET system for use in large geographic areas, such as areas encompassed by an IXC network, or which are larger than a LATA or a metropolitan area. The system uses self-healing rings which are interconnected. Some of the rings are stacked within the same physical routes in order to minimize the number of ring terminals on each ring.

Abstract: In a telecommunications network operable for routing calls such as 800 calls, to a plurality of customer destinations, a system allows the customer to configure the routing of calls by entering selected call routing criteria such as a call-routing map associated with a time frame for implementation thereof included as part of an overall routing plan. The routing map includes the desired allocation of calls placed from a customer defined origination region to selected ones of the customer's call receiving destinations. Using the customer supplied criteria, the system then composes a set of call-handling statements, also called time features, which the network then compiles into an executable routing scheme for translating the dialed number into the physical number associated with the selected customer destination.

Abstract: In order to place a communication device rapidly in communication with a destination, the preferred device is operable upon activation to dial a carrier direct, i.e., "cut through" number in order to place the device directly in communication with an interexchange carrier (IC). This eliminates the need and thus, the time, required for the local exchange carrier (LEC) to access a database in order to identify the IC from the NPA portion of a dialed number. By using automatic number identification (ANI), the IC determines that the calling number is associated with a particular device and, in response, automatically retrieves and routes a number for the called destination, thereby avoiding additional transaction time for translating a dialed, toll-free number into a ten digit on-net number.

The method and apparatus provides for the monitoring of the data and clock signals routed over the link (14) without tapping into the control signals routed over the link (14).

Abstract: The invention is an ATM transport system that transports user information from a continuous signal transport system. The ATM transport system uses telecommunications signaling associated with the continuous signals to determine if the continuous signals are transporting any user information. If so, ATM cells containing user information are generated and transmitted, but if not ATM cells are not generated and transmitted. The invention includes an ATM interworking multiplexer and in some embodiments, a processor.

Abstract: The present invention is a service control point (SCP) for use in a telecommunications network, and in particular, as a component of a telecommunications signaling system. The SCP includes multiple databases which allow routing plans to be stored and implemented. The SCP is operable to accept queries from switches for routing information. The SCP is further operable to reply to these queries with information identifying a connection as opposed to a routing number.

Abstract: A system and method for conducting a dial-in telephone poll prompts callers at remote terminals to participate in the poll by selectively dialing a telephone number corresponding to a specific response to the poll. Each call from a poll participant is received at a switch that is the originating switch for that call. The originating switch also receives caller data indicating the dialed number associated with the call. This caller data is forwarded to a processor associated with the originating switch for counting the number of calls placed to each telephone number associated with the poll. The associated processor may also include a polling table containing a list of telephone numbers associated with the poll and a corresponding list of message IDs. Upon receiving caller data from an originating switch, the associated processor increments a counter for the dialed number and returns a corresponding message ID to the originating switch.

Abstract: A telecommunications system handles 800 calls between first and second networks in different countries. In the preferred embodiment, call handling equipment of the second network receives a call from a call origin in the first network, wherein the call was placed using an 800 number corresponding to a destination in the second network and wherein the second network includes interexchange carriers and local exchange carriers. Preferably, the call is received in call handling equipment of one of the interexchange carriers and carried to the destination by the interexchange carrier to which the 800 number is assigned. In one embodiment, the call is reoriginated after receipt by the call handling equipment of a local exchange carrier which routes the call to the assigned interexchange carrier. Billing charges are assessed to the origin for international toll charges and to the destination for 800 toll charges in the second network.

Abstract: The present invention is a method and system which can be applied to supply a constant bit rate link with digital information from a packet or cell based link, such as an Asynchronous Transfer Mode (ATM) link. The present invention automatically provides compensation information to a buffer supplying the constant bit rate link with information. The compensation is not used if packets or cells are made available in the buffer.

Abstract: In a telecommunications network, a toll fraud detection system analyzes call placement information concerning toll calls placed using billing numbers for unauthorized use of billing numbers. In the preferred embodiment, a set of artificial intelligence rules operate on the placement information to develop an indication that the use of a particular billing number is unauthorized.

Abstract: The present invention is a method of establishing telecommunications between a communication device and a predetermined destination by way of a telecommunications network. The network has at least a first network and a second network, wherein the first network establishes communications between a communications device and a second network. The steps provide for configuring the device to be activatable for transmitting a predetermined string associated with the second network, activating the device to transmit the predetermined string, and in response, establishing communication between the device and the second network. Information is received into the second network from the first network associated with the identity of the communication device, and, in response, retrieving data comprising a destination number previously stored in association with the device information, and establishing the communication with the destination in accordance with the retrieved destination number.

Abstract: A system (400), in its receiver aspect (e.g. 402), interconnects a terminal link (451) to either a first autonomous link (421) or a second autonomous link (431) depending upon the error conditions on the first and second links. The second link redundantly propagates the same data stream as the first link both in Extended Superframe Format (ESF) as generated in a transmitter (401) of the system. The two independent data streams are aligned in the receiver to compensate for the propagation delay difference between these two links. A predetermined number of first and second ESF superframes are stored in buffers during calculation of logic errors, if any, in each of the ESF superframes using the check data in each ESF superframe.

Abstract: In a telecommunications network using data packets for signaling, network components, such as signal transfer points, service control points, and switches, transfer a signaling packet to the network for transmission to a destination component only if that signaling packet is different from the previous packet sent to the same destination. The signaling packets are transferred over respective virtual channels assigned to respective pairs of network components.

Abstract: Apparatus, operating in a digital communication system, for interconnecting a primary or a secondary network to an output port. The primary and secondary networks are redundant networks having point-to-point topologies (125, 130) or point-to-multi-point topologies (210, 215). When connected in a point-to-point network topology that supports extended superframe format (ESF), the apparatus functions as an error correction switch and; when connected in a point-to-multi-point network topology, the apparatus functions as a DS1/0 protection switch. In its receiver aspect, the apparatus stores frames of digital data received from each of two redundant networks, inspects certain error codes contained in the received data and, in response to these error codes, selects the digital data originating from one of the networks that does not exhibit an error code. The data selection process uses a time-slot interchanging (TSI) technique.
