  • Patent number: 7068776
    Abstract: A method and system for automatically completing long distance, international and local telephone calls using a preselected discount telephone service. A R.A.T. sensor array monitors a telephone line for activity. When the dialing of an outgoing call is detected, a central processing unit, in conjunction with a DTMF decoder, determines whether the call being made is a discount call by detecting whether predetermined positioned digit(s) is a predetermined number or set of numbers. If the number dialed is a discount call, the DTMF generator dials a predetermined prefix and/or access code resulting in completion of the call at a discounted rate.

  • Patent number: 7062237
    Abstract: A circuit for regulating the power provided to a load connected to an output of a power amplifier. The circuit includes an amplitude detector that outputs a voltage corresponding to the amplitude of the signal outputted by the power amplifier. This output voltage is a function of the impedance of the load. Thus, when the impedance of the load changes, the output voltage also changes. Given a constant current into the load, it is the load impedance that determines the power delivered to the load. Therefore, because the output voltage reflects changes in the impedance of the load, the output voltage can be used by a regulator circuit to maintain a constant output power, regardless of changes in the impedance of the load.

  • Patent number: 7050564
    Abstract: A communication system is disclosed that generates call progress tones for a call. The communication system is comprised of a calling device and an originating system. Examples of the calling device include a telephone, a cellular phone, a computer, and a fax machine. To place a call, the calling device transmits set up messages to the originating system. The originating system transmits set up messages to a terminating system to set up the call. The originating system receives acknowledgment message from the terminating system in response to the set up messages. The originating system generates a call progress message and transmits the call progress message to the calling device. The calling device generates a call progress tone based on the call progress message and plays audible sounds that represent the call progress tone. By having the calling device generate the call progress tones, the originating system is advantageously available for other communications.

  • Patent number: 7039175
    Abstract: A PSTN (Public Switching Telephone Network) device includes a Dynamically Configurable Signaling State Machine (DCSSM). The DCSSM can be programmed to recognize multiple signaling templates. The DCSSM can also be programmed to modify existing recognized standardized signaling templates. Programming is accomplished via a configuration interface. Commands are sent to the DCRSSM via the PSTN device's configuration interface. When the trunk controller receives a signal or is required to transmit a signal, the DCSSM executes the directives configured with the programmed signaling templates within a signaling state machine.

  • Patent number: 6992510
    Abstract: A multiplier circuit has an analog multiplier with two signal inputs. A respective switching device is connected to each one of the two signal inputs of the analog multiplier for periodically reversing the polarity of the input voltages. A clock signal that can be fed to the switching devices has a changeover frequency that is preferably greater than or equal to twice the useful signal frequency. This suppresses offset-governed crosstalk of the input signals to the output of the analog multiplier. This principle can also be employed in quadricorrelators.

  • Patent number: 6980639
    Abstract: An INAP processing method for communication between a SSP and TCAP. When an INAP message is sent from the INAP of the SSP to the TCAP, a TC component to be transmitted is generated, an invoke ID and dialogue ID are allocated to the generated TC component, and a TC primitive corresponding to the state of an allocated dialogue is created and encoded, to be sent to the TCAP through the TCAP interface block. When the INAP of the SSP receives an INAP message from the TCAP, the received INAP message is decoded based on the type thereof and a corresponding SCP relationship object is found using the dialogue ID included in the decoded INAP message. When the IC component and IC primitive are contained in the decoded message, the IC primitive is executed first and then the IC component is processed. When a corresponding call has been processed, the found SCP relationship object is deleted, finishing the dialogue with the SCP.

  • Patent number: 6970551
    Abstract: A method for uniquely identifying calls having the same originating number and dialed number, and network components adapted to carry out that method. A Parking Manager receives a Park Request that includes the originating number, the dialed number, and a Network Call ID (Identification). The Parking Manager accesses a pool of Dialed Number Identification System (DNIS) override digits associated with the dialed number and returns these digits with the response to the Park Request. The originating number and DNIS override digits uniquely identify the call, and are combined with the destination number, and the combination is flagged as pending in the Parking Manager. The DNIS override digits are received by an Interactive Voice Response (IVR) system that uses a many-to-one mapping to identify the dialed number and complete the call, and returns a call arrival signal to the Parking Manager including a PPID generated by the Voice Response system to Parking Manager.

  • Patent number: 6965669
    Abstract: In a call center with automatic answering, the availability of an agent is verified in order to prevent open connections when the agent unexpectedly leaves his or her station and fails to give proper notice. Verification may be provided by sensing speech activity of the agent when greeting a calling party or in response to an incoming-call signal. In other embodiments, verification may be provided by checking an audio device allocated to the agent, for example checking whether the agent is wearing his or her headset, or whether the headset is operably connected to the call center.

  • Patent number: 6952572
    Abstract: An image rejection mixer includes first and second mixers, a phase shift circuit and a summer. The first mixer receives an RF input signal and a first local oscillator (LO) signal and generates a first intermediate frequency (IF) output signal. The second mixer receives the RF input signal and a second LO signal and generates a second IF output signal. The first LO signal is a phase lag signal (sin ?lot) and the second LO signal is a phase lead signal (?cos ?lot), where ?lot is a frequency signal generated by a local oscillator. The phase shift circuit is connected between the summer and the first mixer, receives the first IF output signal and generates a phase lag signal. The phase shift circuit causes the phase lag signal to lag the first IF output signal by about 90 degrees. The summer is connected to the phase shift circuit and the second mixer, receives the second IF output signal and the phase lag signal, and generates a combined IF output signal.
