摘要:
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 structure, 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.

Integrated communications systems having a scalable or upgradable TDM switch fabric (i.e., e.g., TDM-controlling switch/MUX) are disclosed. At a first point in time a system is first sold, installed and utilized with a first TDM capacity, using a first TDM switch/MUX controlling a first set of TDM streams operating at a first frequency. A first set of line and other cards (e.g., DSP resources) are provided to provide or receive the first set of TDM streams. At a second point in time the system is upgraded by installation of a second TDM switch/MUX; the second TDM switch MUX controls the first set of TDM streams operating at the first frequency and also controls a second set of TDM streams operating at second frequency, which is a frequency different and preferably higher as compared to the first frequency. With at least some of the first cards coupled to the TDM bus, the second TDM switch/MUX couples TDM streams to and from the first cards using the first streams at the first frequency, while concurrently coupling TDM streams to and from the second cards using the second streams at the second frequency. The first switch/MUX preferably operates concurrently with the second switch/MUX to couple streams to and from the TDM bus (e.g., from an HDLC or multi-protocol framing engine, etc.), while the first switch/MUX does not operate to control the TDM bus, as this function is carried out by the second switch/MUX.

A method for operating a communications system is disclosed. At a first point in time, the communications system is operated using a first TDM switch/MUX controlling a first set of TDM streams operating at a first frequency. At a second point in time, a second TDM switch/MUX is installed in the communications system which controls the first set of TDM streams operating at the first frequency and also controls a second set of TDM streams operating at a second frequency that is different as compared to the first frequency. The second TDM switch/MUX couples TDM streams to and from the communications system at the first frequency, while concurrently coupling TDM streams to and from the communications system at the second frequency, and an upgradable switch/MUX capability is provided in the communications system.

Systems and methods by which voice/data communications may occur are disclosed. In particular, systems and methods are provided with a computing system having a multi-bus structure, including, for example, a TDM bus and a packet bus. An integrated communication system is coupled to a digital telecommunications link, the communication system providing voice and data communications to a plurality of users. At least a first packet bus is coupled to one or more packet-based devices and adapted for transferring packetized data to and from the system. One or more time division multiplex (TDM) buses are coupled to one or more telephony devices. Data routing resources are provided internal to the integrated system. A network interface module couples data to and from a data router external to the integrated system. The data router external to the integrated system is coupled to the first packet bus. Data is routed via the external data router through the network interface module and coupled to data channels of the digital telecommunications link, while voice data is selectively coupled to voice channels of the digital telecommunications link.
