Having Shared Or Common Switching Control Patents (Class 379/268)
  • Patent number: 5550911
    Abstract: A method to allow certain types of adjunct applications for telecommunications networks that require caller interaction during call setup to temporarily access the adjunct and then be released back to the network for routing to the final destination. Specifically, when the call enters the network, the network originating switch redirects certain calls to the adjunct. The adjunct may be locally homed directly off the originating switch or may be homed remotely off a centrally located switch. Once the call has been routed to the adjunct and caller interaction has been completed, the adjunct releases the voice connection back to the switch which then routes the call to its final destination.

  • Patent number: 5471526
    Abstract: A method and apparatus for detecting events occurring in a telecommunications network is disclosed which comprises stored program control (SPC) exchanges, each SPC exchange comprising a switch and processors for executing software programs to control the switch. Code sequences, or daemons, are implanted in selected portions of the software programs, each code sequence including a conditional statement responsive to certain events and at least one activity resulting from the detection of a certain event satisfying the conditional statement. A lock value is assigned to each of the code sequences, each lock value uniquely identifying the corresponding code sequences and being operable to activate the processor for executing the code sequence. A key value is compared to each lock value for selectively activating the processor to execute the code sequence when the key value equals the lock value.

  • Patent number: 5467367
    Abstract: A telephone exchange system of this invention has a terminal connected to an extension by radio. As a radio communication modulation method, a spread spectrum method is used. A speech signal received from a line by the telephone exchange system is exchanged by an exchange switch, and is supplied to a data conversion unit. The data conversion unit causes a serial/parallel converter to covert a serial input signal into a parallel signal. The converted parallel signal is subjected to spread-spectrum modulation in units of parallel bits. The modulated signal bits are added to each other by an adder, and the sum signal is multiplexed on a carrier signal. The multiplexed signal is transmitted to the terminal. Upon reception of the signal, the terminal causes a phase synchronization circuit to generate an inverse spread code corresponding to a spread code, and synchronized with the reception signal, and inversely spreads the reception signal using the generated inverse spread code.

  • Patent number: 5455827
    Abstract: A switch provides time multiplex connections between ports in a telephone system. These connections are organized according to protocols located in software programs on an Integrated Multi-Protocol Processing unit (IMP). IMP includes several processing systems for processing the several protocols received by the telephone switch. Each of these IMP's then processes the respective protocol to produce switching control information. This switching control information is then transmitted to the telephone switch on a separate communications channel. The switch then uses this process protocol information to establish and remove telephone connections, according to the particular protocol received.

  • Patent number: 5434851
    Abstract: Digital telecommunications switching system. A plurality of identical switching controllers (ASC) are connected to one another via a switching network (ICN) that sets up line connections and, as in the case of a super-massive parallel computer, that operates simultaneously on the execution of small sub-operations relating to the same connection. A portion of the control units have special processors (DSB, CTP, I/F) allocated to them. The switching network has a call throughput rate that is greater than the requirement of the actual set up of line connections.

  • Patent number: 5373553
    Abstract: A group of rules is stored in memory of a computer system wherein each rule defines an allowable combination of configurable parameters that are controllable by command message. Inputs are received from the user indicating the specific ones of the configurable parameters to be controlled. The selected parameters are compared to the rules to determine sets of configurable parameter communications which are allowed; a first list of such parameters is generated. One of the sets of parameters from the first list is entered on a second list. The first list is modified to exclude sets of configurable parameters which include a control parameter included in the set entered on the second list. This process is repeated until all selected parameters by the user are contained on the second list. The second list of parameters each have a corresponding command message and thus, a group of command messages are automatically generated to control the selected parameters.

  • Patent number: 5138657
    Abstract: This invention relates to apparatus and a method for controlling a Digital Access and Crossconnect System (DACS) from a connected toll switching system. All control messages from operations support systems (OSS) for making crossconnect changes in the DACS are first routed to the toll switch. The toll switch extracts information needed to update its database and sends a control message to the DACS. In addition, the toll switch responds to changes in traffic patterns, perhaps due to the loss of a transmission facility, to generate a crossconnect change message to the DACS to rearrange facilities for more optimum performance. Advantageously, the OSSs for DACS control and switch control is combined and the toll network is made more responsive to traffic pattern changes and to losses of transmission facilities.

  • Patent number: 4631364
    Abstract: There is disclosed a communication system and operating method wherein the manner in which all telephone calls are displayed at a station set allows uniform user operations to originate and terminate those calls. This is accomplished by having all calls dynamically assigned to the same set of general call appearances (buttons on a multibutton station set). There are no call appearances that are dedicated to specific call types. This allows the station set user to perform the same set of operations on all calls by using the same sequence of physical operations independent of the type of call. Additionally, the system may reserve one call appearance button at a station set for special use.
