摘要:
A telecommunication system that can integrate the capabilities of broadband components with the capabilities of conventional circuit switches. A signalling processor (140) receives and processes a first telecommunications signalling message (160) for the call to provide control and signalling messages (162, 163, 164, 165, 166) that identify the selection and transfer the control messages to the ATM internetworking multiplexers (110, 112, 114) that accepted the access connection for the call. The multiplexers (110, 112, 114) convert user information from the access connection into ATM cells for transmission over the virtual connection in accord with the control messages (162-166). An ATM cross connect system (120) operationally connected to the multiplexers (110, 112, 114) routes the ATM cells based on the virtual connection identified in the ATM cells. The narrowband switches (130, 132) provides the service to call based on the telecommunication signaling message.

The invention is a system for interfacing an ISDN or non-ISDN system with a broadband system. The broadband system can be an ATM system. The invention can process the ISDN signaling (1054) to select ATM connections (1130) and then interwork the ISDN connections (1120, 1123) with selected ATM connections (1030). The invention can interwork ISDN signaling and SS7 signaling (1054, 1064). The invention can also process SS7 signaling (1064) to select ISDN connections (1020, 1022) and then interwork ATM connections (1030) with the selected ISDN connections (1020, 1022). The invention can also interwork ISDN systems with non-ISDN systems.

The invention is a tandem system (300) for providing a tandem connection for circuit-based traffic. This tandem system comprises an ATM cross-connect (370), ATM interworking multiplexers (360, 364), and a signaling processor (350). 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 outgoing circuit-based connections used by the multiplexers.
摘要:
A system and method to detect a call trigger during a call without requiring a service platform to remain connected to the call. A first communication device (106) transmits a call having call signaling and user communications. A signaling processor (112) receives the call signaling from the first communication device and selects a connection to a second communication device (108). An interworking unit (114) receives the user communications from the first communication device and converts the user communications from a time division multiplex format to asynchronous transfer mode cells that identify a selected connection to the second communication device. The interworking unit detects a call trigger in the user communications. The interworking unit transmits call trigger data to the signaling processor. The signaling processor processes the call trigger data and, upon validating the call trigger, instructs the interworking unit to transport the user communications to asynchronous transfer mode cells that identify the selected connection to the thrid communication device (110) and transports the user communications to the third communication device.
摘要:
A system to interworking a call between a plurality of networks (302, 304, 320) having different formats. The system has a GR-303 system (304), an integrated services digital network system (302), a service platform (310), and an asynchronous transfer mode system (320). The system has a signaling processor (202) 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 (304), the integrated services digital network system (302), the service platform (310), or the asynchronous transfer mode system (320). The signaling processor (202) transports a control message identifying the selected connection. An interworking unit (204) receives the user communications and the control message. The interworking unit (204) 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.
