  • Patent number: 5608790
    Abstract: This invention relates to arrangements for interconnecting a plurality of stand-alone switches by data and communication channels (the latter typically used for communicating voice signals) in such a way as to make the plurality of switches act as if they were one switch. The invention further relates to arrangements for permitting groups of lines, the groups connected to different stand-alone switches, to be treated essentially as if they were connected to a single switch. Each switch of a symbiotic network (a group of stand-alone switches) or a virtual symbiotic network (the grouping of the groups of lines) accesses pertinent data in its own data base or the data base of one of the other switches of the symbiotic or virtual symbiotic network and treats the results of such data base accesses as if they were made internally in the switch.

  • Patent number: 5590129
    Abstract: An arrangement for controlling a large time slot interchange (TSI) unit. The TSI unit is a single stage unit for interconnecting any incoming time slot with any outgoing time slot. No blockage is incurred in such a single stage switch. A plurality of module processors is used each for controlling a group of TSI slices, the size of the group being selected to match the capabilities of the module processor. The module processors communicate with each other in order to cooperate in setting up connections through the TSI unit. Each module processor processes terminating, originating, incoming or outgoing processes for calls connected to the terminals served by the module processor. Advantageously, a large non-blocking TSI unit is made available for serving a large switching system without incurring blockage.

  • Patent number: 5544235
    Abstract: A telecommunication network having a switching system connected to a called station by a line that provides notification to a called party of information relating to an incoming call. This information generally consists of the called number, but may also include an extension or other code. The called party identification is delivered to the called telephone station set during the silent period after ringing, or, advantageously, before ringing starts. A signal (e.g., FSK) is sent to the called telephone station set shortly before the ringing signal is sent to the called station. A converter at the customer premises receives the FSK signal and demodulates it. A control unit connected to the converter then causes the called DN to be displayed, may cause a distinctive ring to be made, or take other action depending upon its program.

  • Patent number: 5226042
    Abstract: A method of establishing an N time slot connection through first and second, single-buffered time slot interchangers where the time slots interconnecting the two time slot interchangers, referred to herein as network time slots, are chosen in accordance with particular selection criteria such that all N time slots received by the first time slot interchanger in a single frame, are also transmitted from the second time slot interchanger in a single frame.

  • Patent number: 5119366
    Abstract: A call processing method for distributed switching which substantially increases the percentage of calls that are intra-module calls by distributing the members of trunk groups among a plurality of switching modules and biasing the processing of a call originating on one switching module such that an available trunk group member on that same switching module is assigned to the call if possible. The path hunt function for intra-module calls is separated from the corresponding function for inter-module calls and only the latter function is performed by the system central control. The separation is achieved by dividing the set of switch path resources, e.g., channels or time slots, associated with a switching module into two disjoint subsets--a first subset for intra-module call connections and a second subset for inter-module call connections.

  • Patent number: 5115425
    Abstract: A distributed switching system where calls are processed in one of two call processing modes: 1) in a first call processing mode, available paths through a time-multiplexed switch (TMS) are selected without reference to whether the paths are presently established through the TMS, and 2) in a second call processing mode, the available path selections are made from only established paths through the TMS. Reliability is improved without an addition of hardware to the system because a transition may be advantageously effected to the second call processing mode in response to any system failure where it becomes impossible to select new TMS paths or to control their establishment, but where the established TMS paths at the time of the failure are still usable for new calls. Once such transition is completed, the system can continue to operate to complete calls between switching modules (SMs) in a reduced performance mode dependent on the number of TMS paths established between the SMs at the time of the failure.

  • Patent number: 5105420
    Abstract: An illustrative method and structural arrangement for reconfiguration of switching system functional units where although the distributed control entities and the distributed switch units of a switching system are in fixed association, the association between peripheral circuits and the control and switch units is not fixed. Rather a group of peripheral circuits is connectable to at least first and second ones of the distributed switch units. When the group of peripheral circuits is connected to the first distributed switch unit, the control unit associated with the first distributed switch unit processes calls to and from the group of peripheral circuits. When the group of peripheral circuits is connected to the second distributed switch unit in response to a reconfiguration signal, the control unit associated with the second distributed switch unit processes calls to and from the group.

  • Patent number: 4979164
    Abstract: The switch units of a distributed switching system are connected by a central switch for advancing connections between the switch units and also by inter-switch unit trunks. To save switch unit resources, trunk services such as scanning and signaling are not provided to the inter-switch unit trunks while the central switch is available for advancing connections. When the central switch becomes unavailable for advancing connections, as detected by control units in the switch units, the inter-switch unit trunks are connected to the trunk serving circuitry of the switch units and connections are advanced between switch units over the inter-switch unit trunks. Serving the inter-switch units trunks while the central switch is unavailable requires additional switch unit resources but provides for continuity of service which would to otherwise be lost due to the unavailability of the central switch.

  • Patent number: 4943999
    Abstract: A switching arrangement is disclosed in which connections are advanced between lines and trunks of a first telecommunication switching system via a central switch of the first telecommunication switching system and, when the central switch is unavailable, via a first trunk from the first telecommunication switching system to a second telecommunication system and a connection through the second telecommunication switching system to a second trunk back to the first telecommunication switching system. The first switching system comprises a first and second unit connected by the first and second trunks, respectively, to the second switching system. A control unit in the first switch unit determines when the central switch is unavailable and in response to a dialed request for connection to a line or trunk at the second switch unit, advances the connection via the first trunk to the second switch system.

  • Patent number: 4866708
    Abstract: A communication channel ownership arrangement where two call units (switching modules) each own certain ones of the bidirectional channels between the units. By virtue of ownership, a call unit can immediately assign owned channels to calls without consulting the other call unit. While the ownership of channels to calls may be artibrary at system initialization, ownership is modifiable on a per-call basis to dynamically adapt to the actual directional traffic patterns that are present at a given time to minimize the coordination and communication required between the call units.

  • Patent number: 4805166
    Abstract: A switch path reservation arrangement where any paths that are established for calls between two switching modules are reserved such that most future calls between the two modules are set up promptly using previously reserved paths with a minimum of inter-module message communication. Relatively few calls require a path hunt involving inter-module negotiation to determine a new path. Such new path is not only assigned for the call but also thereafter reserved for calls between the two modules. Path reservations are changed only when required to avoid blocking a call. Thus, the path reservation arrangement adjusts the number of paths between modules on a per-call basis to dynamically match the call traffic load.
