摘要： A plurality of M PBXs (32-34, 36-39) are coupled to a plurality of N nodes (40-44) forming a Distributed Transit Private Branch Exchange (PBX) (30). The plurality of N nodes are located remotely from each other and form a wide area network. Each node is coupled to predetermined ones of the other nodes via separate links (45-49) so that each node is able to communicate with all other nodes. One or more D-channel Server Modules (DSMs) (50, 51, 54, 56) are located in predetermined nodes of the plurality of N nodes. Each DSM is associated with a plurality of D channels which are each coupled to a separate interface device in the same node or different node by means of a link for receiving and transmitting signaling data to one of an associated predetermined PBX of the plurality of PBXs. Each DSM is arranged to analyze the call signaling message received via a D channel and, based on routing information, either route the call back to the same PBX or a different PBX attached to the same DSM when the calling and called subscribers are located in the PBXs attached to the same DSM, or route the call to a remote DSM when the call is routed between remote PBXs that are not coupled to the same DSM. The remote DSM, in turn, routes the call to the PBX attached to that DSM. Therefore, each DSM only controls calls addressed to a DSM associated with that DSM, and when a call is not addressed to a PBX associated with that DSM, the DSM passes any call control to a destination DSM associated with a PBX to which the call is addressed.

摘要： A telecommunication network may be arranged in accord with the invention so that a change in provisioning data occurring at one element of the network is automatically supplied to the other elements of the network, thereby eliminating the need of having a network administration facility to communicate manually the change to the other network elements. For example, if a local central office switch is rehomed from a first toll switch to a second toll switch, then the first and second toll switches form messages respectively characterizing the rehome and then send the messages to each of the other network toll switches so that the other toll switches may update their respective routing and trunking data relating to the rehomed switch. The network is also arranged to implement a rule-based, end-to-end routing scheme which automatically selects a routing path from multiple candidates based on (a) class-of-service parameters and (b) availability of network capacity. The automatic selection of a routing path thus replaces the provisioning of routing data in the toll switches, which data was priorly needed to select the appropriate routing path.
摘要翻译：可以根据本发明布置电信网络，使得在网络的一个元件处发生的供应数据的改变被自动地提供给网络的其他元件，由此不需要使网络管理设备能够手动地通信改为其他网元。例如，如果本地中心局交换机从第一个长途交换机重新连接到第二个长途交换机，则第一和第二长途交换机形成分别表征该路由的消息，然后将该消息发送到每个其他网络长途交换机，使得另一个长途交换机可以更新它们各自的路由和与被重新连接的交换机相关的中继数据。该网络还被设置为实现基于规则的端到端路由方案，其基于（a）服务等级参数和（b）网络容量的可用性自动选择来自多个候选者的路由路径。路由路径的自动选择因此取代了长途交换机中路由数据的供应，先前需要哪些数据来选择适当的路由路径。
