Abstract: The invention is a system for providing virtual connections through an ATM interworking multiplexer on a call-by-call basis. A signaling processor receives signaling for a call and selects the virtual connection for the call. The signaling processor generates control messages that identify the selection and transfers the control messages to the ATM interworking multiplexer that accepted the access connection for the call. The multiplexer converts user information from the access connection into ATM cells for transmission over the virtual connection in accord with the control messages.

Abstract: The invention is a tandem system for providing a tandem connection for circuit-based traffic. This tandem system comprises an ATM cross-connect, ATM interworking multiplexers, and a signaling processor. The multiplexer converts the traffic received by the tandem system into ATM where it is routed through the cross-connect and re-converted back into the circuit-based format at an ATM interworking multiplexer. The signaling processor controls the virtual connections and out going circuit-based connections used by the multiplexers.

Abstract: The invention is a provider agent product and method that operates as a software interface between a telephony card and a session manager in an advanced communications network. The provider agent receives event messages from the telephony card indicating on-hook events, off-hook events, and digit events. The provider agent instructs the telephony card to provide dial tone, ring current, ringback, and busy signals to the telephones. The provider agent also exchanges messages with a session manager in the network. These messages include: invite messages, reply messages, join messages, and terminate messages. In response to the above processing, the provider agent instructs the telephony card to interwork telephony signals on a telephony channel with ATM signals on an ATM virtual channel. The provider agent is comprised of a plurality of software objects that are stored on a software storage medium and that include: a controller object, port objects, and event objects.

Abstract: When telephone calls are placed by dialing a special number such as an “800” number, the dialed number is converted to a specially configured translation number that includes a destination output set of digits which are preferably the last four digits of the dialed number. This translation number is transported over the network from an originating switch to a terminating switch which then outputs the output set to the destination. Advantageously, the terminating switch also replaces the prefix portion of the translation number with an output prefix consisting of at least the NXX portion of the dialed number and outputs this prefix along with the output set to the destination for use in call tracking.

Abstract: An ATM reference traffic system records packet information representative of ATM packets transmitted over an ATM network. The system also creates and transmits ATM packets from packet information on a schedule representative of ATM packet transmission over an ATM network. The preferred system uses a personal computer with the operating system modified to schedule events with microsecond resolution while providing interrupts to the operating system on a periodic basis.

Abstract: The invention comprises a telecommunications signaling processor that processes Signaling System #7 (SS7) telecommunications signaling messages to select Asynchronous Transfer Mode (ATM) virtual connections and provide control messages indicating the selected ATM virtual connections.

Abstract: The invention is a system for modifying the VPI/VCIs in ATM cells transferred between two ATM systems on a call-by-call basis. A signaling processor receives signaling for the call and selects a new VPI/VCI for the call. The signaling processor generates a control message that identifies the old and new VPI/VCIs and transfers the control message to an ATM gateway. The ATM gateway modifies the old VPI/VCI in the ATM cells to the new VPI/VCI.

Abstract: A system and method for conversion and transmission of communication signals converts and grooms communication signals in the synchronous digital hierarchy and synchronous optical network formats at low multiplexing levels. In one embodiment, the system receives tributaries from a primary receiver and multiplexes them so as to embed in a payload the tributaries and lower order path overhead as payload components. The payload is converted to a synchronous optical network format and transmitted in a communication signal. However, the payload components remain in the synchronous digital hierarchy format. A converter assembly receives the communication signal and converts and grooms the payload at a virtual tributary group level to a synchronous digital hierarchy format without changing the payload components embedded therein. The converter assembly delivers the communication signal to a receiver where the payload components can be removed from the payload and delivered to a primary receiver.

Abstract: A system to interworking a call between a plurality of networks having different formats. The system has a GR-303 system, an integrated services digital network system, a service platform, and an asynchronous transfer mode system. The system has a signaling processor that is adapted to receive the call signaling and to process the call signaling to select a connection to one of the GR-303 system, the integrated services digital network system, the service platform, or the asynchronous transfer mode system. The signaling processor thereby selects the corresponding system on the connection. The signaling processor transports a control message identifying the selected connection. An interworking unit receives the user communications and the control message. The interworking unit converts the user communications from the format in which it was received to the format that is compatible with the selected system. The user communications are then transported on the selected connection.

Abstract: An improved method and apparatus for administrative monitoring of a calling card fraud prevention system is disclosed. An administrative monitor continuously oversees the functions performed by components of the fraud prevention system and thereby detects abnormalities in system performance. The administrative monitor regularly compiles status information from system components and applies a set of predefined thresholds in order to determine whether abnormalities are present. Upon detection of an abnormality, the administrative monitor generates a health warning, which is displayed on workstation monitors to provide notice of the problem.

Abstract: The invention is a system and method for processing connections. Connection identifiers are assigned to indexes and stored in corresponding index latches. When communications arrive over a particular connection, the identifier for the particular connection is provided to all of the index latches. The index latch that stores a matching connection identifier provides its associated index. The index can be used to access a memory location that houses a processing instruction for the particular connection. The invention can be used within ATM multiplexers and gateways to facilitate connection processing.

Abstract: A telecommunications network architecture uses a service host to control the application of enhanced services. In preferred forms, the service host determines the disposition of the call and provides corresponding instructions to the origination switch by way of a service control point (SCP) in response to a request initiated by the SCP upon encountering a service node in the routing tables. The disposition may include routing the call to a media resource and if another call destination is determined, the call is rerouted from the origination switch to the destination while the first routing is dropped.

Abstract: The present invention is an apparatus, system, and method for converting point codes in a signal transfer point in a telecommunications signaling system. The STP converts point codes which designate the origination and destination signaling points for the message. The conversion is based on information defined by the messages, such as origination or destination information. The present invention creates a virtual signaling system which can be reconfigured at the STP by converting point codes, and thus, altering the identities of the signaling points. The present invention is also operable to convert circuit identification codes and transfer integrated services user part messages to a user part.
