A system for managing voice and data communications for at least one user is coupled to at least one wide area telecommunications network and includes at least a processor and data storage resources. A first bus is adapted to couple video data between the system and a video unit coupled to the system under control of the processor. A second bus is adapted to couple audio data between the system and a microphone unit coupled to the system under control of the processor, and audio data are coupled to a TDM bus in the system operating under control of the processor. A digital transmission link of the wide area telecommunications network couples the video and audio data from the system, under control of the processor. A user participates in a video call with the video data, while concurrently the user participates in a telephone call with the audio data. Voice communications of the telephone call that stay in a circuit-switched form are provided via the TDM bus, and the video call and the telephone call can provide a conference call.

A system for managing voice and data communications coupled to a wide area telecommunications network. Video data is coupled between the system and a video unit under control of a processor. Audio data is coupled between the system and a microphone unit under control of the processor. The audio data are coupled to a TDM bus in the system operating under control of the processor. The video and audio data are coupled to a digital transmission link of the wide area telecommunications network. A user participates in a video call with the video data, while concurrently the user participates in a telephone call with the audio data. Voice communications of the telephone call that stay in a circuit-switched form are provided via the TDM bus. The video call and the telephone call provide a conference call.

A video conferencing method is provided in a system for managing voice and data communications to a plurality of users. Computer data is communicated between the system and one of a plurality of computers coupled to the system over one or more packet buses. Voice data is communicated between the system and one of a plurality of telephone devices coupled to the system. The voice data is coupled to a TDM bus in the system, and the voice data and/or the computer data are coupled from the TDM bus to a digital transmission link. Video and audio data are coupled between the system and a video conferencing unit and coupled to the TDM bus. The video and audio data are coupled from the TDM bus to a digital transmission link of the telecommunications network. A video conference participant participates in a video conference with the video conferencing unit over the digital transmission link, while concurrently a user participates in a telephone call with one of the telephone devices over the digital transmission link.

Systems and methods for multiple mode voice and data communications using intelligenty bridged TDM and packet buses and methods for performing telephony and data functions using the same

Systems and methods by which voice/data communications may occur in multiple modes/protocols are disclosed. In particular, systems and methods are provided for multiple native mode/protocol voice and data transmissions and receptions with a computing system having a multi-bus structures including, for example, a TDM bus and a packet bus, and multi-protocol framing engines. Such systems preferably include subsystem functions such as PBX, voice mail and other telephony functions, LAN hub and data router. In preferred embodiments, a TDM bus and a packet bus are intelligently bridged and managed, thereby enabling such multiple mode/protocol voice and data transmissions to be intelligently managed and controlled with a single, integrated system. A computer or other processor includes a local area network controller, which provides routing and hub(s) for one or more packet networks. The computer also is coupled to a buffer/framer, which serves to frame/deframe data to/from the computer from TDM bus. The buffer/framer includes a plurality of framer/deframer engines, supporting, for example, ATM and HDLC framing/deframing. The buffer/framer is coupled to the TDM bus by way of a switch/multiplexer, which includes the capability to intelligently map data traffic between the buffer/framer and the TDM bus to various slots of the TDM frames. Preferably, a DSP pool is coupled to buffer/framer in a manner to provide various signal processing and telecommunications support, such as dial tone generation, DTMF detection and the like. The TDM bus is coupled to a various line/station cards, serving to interface the TDM bus with telephone, facsimiles and other telecommunication devices, and also with a various digital and/or analog WAN network services.
