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 for voice and data communications including a scalable TDM switch/multiplexer

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.

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.
