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： Redundancy, expanded switching capacity and fault isolation arrangements for use with an expandable telecommunications system. An inter-nodal network connects a plurality of programmable switching nodes or other nodes. One or more additional inter-nodal networks may be provided across some or all of the ones. The bandwidth provided by the additional network(s) may be used to provide redundancy against failure of the primary network or the nodes, increased switching capacity or a combination of both. In addition, faults which occur either within a particular node or within an inter-nodal network may be effectively isolated and prevented from degrading system performance.

摘要： The present invention is a standardized host-to-switch application program interface (API) for performing call control processing, capable of being customized to meet telecommunications application and network signalling protocol requirements. The universal API comprises one or more generic messages having programmable fields for transmitting commands, status, and data between the host application and the switch. The present invention further comprises a programmable telecommunication switch that provides a user with the ability to define a desired API protocol, either 'standard' or custom in nature, for performing any desired switching functions. The present invention includes a protocol development environment which enables a user to define a separate finite state machine for each port provided by the switch. Each finite state machine may be independently defined by combining a series of elementary processing steps, called atomic functions, into primitives, which are in turn combined with states and events to define the desired state machine. Such state machines may include atomic functions configured to generate predetermined messages under predetermined conditions and containing predetermined information. Such state machines may further include the ability to respond to state events that include the receipt of generic API messages configured to provide the state machine with information from the host application.

摘要： The principle object of the present invention, is to provide flexibility in the routing functions performed in the switching system. Another object is to provide a router (200) that can be centralized in a host computer (24) or distributed among various switching nodes (32b-32f). The router is easily programmable by the system operator to provide different routing algorithms for various calls. The router can be used in a system with a single switching node. However, it is particularly adopted for use in a multiple-switching-node system, either as a central, host resident unit, or as a distributed router resident on the switching nodes. A router embodying the invention uses router tables (201) that are readily configurable by the system operator to route calls based on predefined routing criterion in the incoming or outgoing call.
摘要翻译：本发明的主要目的是提供在交换系统中执行的路由功能的灵活性。另一个目的是提供一种可集中在主计算机（24）中或分布在各种交换节点（32b-32f）中的路由器（200）。系统运营商可以很容易地对路由器进行编程，为各种呼叫提供不同的路由算法。该路由器可用于具有单个交换节点的系统。但是，它特别适用于多交换节点系统，既可以作为中央，主机常驻单元，也可以作为驻留在交换节点上的分布式路由器。体现本发明的路由器使用路由器表（201），其可以由系统运营商容易地配置，以基于呼入或呼出中的预定义路由准则路由呼叫。

摘要： A method and apparatus for conferencing two or more calls in an expandable telecommunications system. The system may include a plurality of nodes connected by an inter-nodal network such that the nodes communicate with each other by exchanging variable-length packets of information. At least one node in the system contains digital signal processing circuitry capable of conferencing the voice information from three or more callers interfaced with the system. Packets containing voice information from each conference participant are preferably transmitted via the inter-nodal network to the node having the requisite digital signal processing circuitry. This node performs a conferencing function on that information, packets the resulting conferenced information and transmits those packets via the inter-nodal network to the nodes interfaced with the conference participants.

摘要： This invention relates to a supplementary services layer (SSL) application (200) in the switching node (32) for the development and execution of subscriber-based supplementary services. The SSL communicates with the L4 application (36) through an L4-L5 interface (240). Therefore, a system operator may configure the switching node (32) to execute supplementary services without intervention from a host application and without modification to the current L4 application. The SSL also communicates with the L5 application in order for that application to integrate supplementary services without further modifications. The SSL comprises a Database Interface Service (202), a Service Object Manager (SOM) (204) and one or more instances of a Supplementary Service Object (SSO) (206; 208). The database interface service (202) provides connection to an external database which stores each subscriber's profile. Each SSO instance (206; 208) implements one or more supplementary services for a call. The SOM (204) exercices overall control over these SSO instances (206; 208).

摘要： A network protocol data intelligence (NPDI) software in the switching node that enables the call processing components in the L4 and L5 applications to interpret and manipulate different network signalling data protocols. The call processing applications are expanded to understand different network signalling protocols and to extract the required information from each protocol's data stream. The NPDI provides the means for the L4 application to convert from one network signalling data format to another either, by itself or in conjunction with the L5 application. Thus, the system operator may configure the switch to perform all call processing functions or by-pass the NPDI and have the L5 application perform these functions. The L4 application may also perform data translation from host applications written against the underlying network protocol to the different signalling protocols from other networks. Thus, a host application written against one network signalling protocol may communicate with an application using another signalling protocol without modification to the host application. The NPDI service further enables the L4 application to convert protocol-specific data from other applications in the system to protocol independent data that can be 'understood' by the L3 and L5 applications. In addition, the L4 application may route calls in the switching node based on network signalling information from the L3 application.

摘要： A telephone switching system comprises a plurality of switching nodes interconnected by a call-switching network. The switching nodes are also linked by a host network to one or more hosts that exercise supervisory control over the nodes. The hosts communicate directly with one or more of the nodes, termed 'switching nodes', by means of virtual connections over the host network. The other switching nodes, termed 'slave nodes', are assigned to host nodes. The hosts communicate indirectly with the slave nodes by way of switching nodes to which they are assigned. Communications between a host and a slave node thus comprise messages: (a) over the host network between the slave node and the switching node to which the slave node is assigned and (b) by way of a virtual connection, between the switching node and the host.
