摘要： A telecommunications switching node that includes at least one resource interface card (108) which serves as an interface for connection to external call processing resources (336). The interface card communicates with the line cards in the switching node directly over the system buses (118, 120, 122, 124), i.e. without passing through the CPU/matrix card (104) and it uses two line card ports to connect to all external resources. The resource interface card (108) also communicates with line cards (106) that are connected to the system buses in other switching nodes in an expanded switching network. Its resources are thus available to ports in the other nodes when those nodes have available ports that are not occupied with other tasks. For communications with the latter ports, the resource interface card (108) transmits information through the CPU/matrix cards (104) on its switching node and on the nodes where the communicating ports reside. Thus for communications with ports on its switching node, the interface card (108) receives information on the incoming bus (340) and transmits it on the outgoing bus (342) and for communications with ports on other nodes it receives information on the outgoing bus (342) and transmits it on the incoming bus (340).

摘要： The L4 application in the switch is expanded to permit functions previously performed exclusively in the L5 protocol application. Moreover, the L4 application is programmable by the system operator so that the system operator may expand the predefined set of L4 call management operations to accommodate his call processing requirements. Overall supervision of the call-management operations was previously limited to the L5 applications. However, the ability to program the L4 application enables the system operator to decide which call processing operations will be managed by the L5 applications and which operations will be managed by the L4 application. The system operator may thus define, in the L4 application, a proprietary call model that instructs the switching node to manage all incoming calls, or the system operator may specify the call model on a channel by channel basis. The latter arrangement programs the switching node to use different call-processing protocols among the various channels. In addition, the user may either re-define or define entirely new application programming interface (API) calls for communications between the host and switching node and/or between the switching node and ports.

摘要： A telecommunications switch includes a plurality of digital signal processing modules resident on a communications services card, wherein each module includes its own time slot interchange (TSI). Significantly, this allows each digital signal processing module to simultaneously receive all information transmitted from the line cards. In addition, since each digital signal processing module includes its own dedicated TSI and each of these TSIs is connected in parallel to the same TDM bus, one or more TSIs may simultaneously output data onto the TDM bus during a time slot. Adavantageously, this allows multiple TSIs to be assigned to the same transmit time slot and mux transmit time slots at the bit level. For example, if a first TSI on the digital signal processing module needs only three bits of an eight bit time slot, and a second TSI needs five of less bits, then both TSIs can be assigned to transmit during the same time slot. The first TSI would output data on, for example, the three least significant bits, while the second TSI would output its data onto the remaining bits of the time slot.

摘要： A user-programmable telephone switch which resides within a commercially available personal computer. The switch is controllable by either the personal computer's microprocessor or a separate, external host connected to an interface provided within the switch. The switch includes a CPU/matrix card that contains a time slot interchange and a CPU running under a real time operating system. The CPU/matrix card controls the overall operation of the switch in accordance with messages received from the operative host. In general, those tasks or functions which must be performed in real time are the responsability of the switch, as opposed to the internal or external host. Within the switch, certain tasks or functions may be delegated by the CPU/matrix card to intelligent line cards which contain their own microprocessors having substantial call processing capability.
