  • Patent number: 6078656
    Abstract: A method for enabling a plurality of Local Service Providers within a common Numbering Plan Area (NPA) to serve Subscribers of the plurality of Local Service Providers. The method includes the step of assigning to each Subscriber of a Local Service Provider within the common NPA a unique three digit code, hereinafter referred to as a SPA code. The service provider area (SPA) code is used by the telephone system in the same manner presently used for routing calls made when a calling Subscriber dials the NPA code of the called party. Here, however, the SPA code is not dialed by the calling Subscriber. The dialed directory number, NXX-XXXX, of a called Subscriber subscribed to a different Local Service Provider, is sent to a database. The database maintains a record of the relationships between the directory numbers of Subscribers and the SPA codes of the Subscribers. The database retrieves the SPA code associated with the dialed directory number presently serving the called Subscriber.

  • Patent number: 6028924
    Abstract: A method and apparatus for providing a telephone operating company with the ability to rapidly deploy advanced services into a public switched telephone network includes a programmable service node interacting with a programmable switch matrix. The call processing of a call (associated with one or more ports on the programmable switch matrix) is controlled externally when particular triggering criteria is met (i.e., the call requires or desires external control). When the triggering criteria is met, the service node outputs a new call event notification message over a communications link to an external unit and receives one or more messages over the same link. Call control processing is achieved through this high-speed communications link between the programmable switch matrix and the external unit using a communications protocol defining a comprehensive set of primitives (instructions) for call manipulation and control at the programmable switch matrix which are received by the programmable service node.

  • Patent number: 5974132
    Abstract: The present invention is a novel architecture design for adjunct based architectures. The architecture is built on two key principles; routing traffic based on geographic origin and routing based on customer group. In order to implement the geographic routing, the communications network is split into regions. A method used to achieve optimal regions is described. Further realization of the geographic routing entails a design of the architecture regions, determining the number of adjuncts/region and equally distributing the loads across the adjunct sites. Also, described is the method for optimally homing traffic between the OAS and TAS A and between TAS A and TAS B. The architecture eliminates deficiencies in prior art architectures such as intertoll focusing, architecture instability and reliability.

  • 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.
