  • Distributed transit private branch exchange
    Patent number: 5903571
    Abstract: A plurality of M PBXs are coupled to a plurality of N nodes forming a Distributed Transit Private Branch Exchange (PBX). 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 so that each node is able to communicate with all other nodes. One or more D-channel Server Modules (DSMs) 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.

  • PBX networking with quality of service control
    Patent number: 5825779
    Abstract: A networking node for interconnecting a local telephone switch such as a private branch exchange (PBX) with other such switches through other nodes, with respective internodal multichannel digital transmission links interconnecting the various nodes, provides service for both data and voice messages. The networking node provides at least two levels (one of which may be zero) of compression for voice messages and permits one of those levels to be preselected for all voice messages from the switch with which the node is associated to a predetermined one or more of the other nodes in the network. A look-up table is stored in memory within the node to control the assignment of particular levels of compression to particular destinations.

  • Method of distributed call control in a distributed transit PBX system
    Patent number: 5805690
    Abstract: A method of Distributed Call Control is provided in a Distributed Transit Private Branch Exchange (PBX) comprising a plurality of Nodes forming a wide area network, and a plurality of D-channel Server Modules (DSMs). The DSMs are located in predetermined ones of the Nodes with each DSM coupled to at least one associated PBX via at least one D channel. The method includes the following steps. First, a listing of all Exchange Codes (ECs) handled by a DSM and each associated PBX coupled thereto is stored in a local routing table of a memory in the DSM. Second, a listing of all ECs handled by all of the other DSMs of the Distributed Transit PBX and their associated PBXs is stored in a remote routing table of the memory in each of the DSMs.
