  • Publication number: 20190320059
    Abstract: A technique for controlling an electronic device thereof is provided. The technique includes, in response to an attachment device being selected by an external device from a list of attachment devices, receiving and storing mapping information in which data configured in a first communication format and data configured in a second communication format in relation to one function of the electronic device to which the attachment device is attached are mapped. In addition, in response to the data configured in the first communication format being received from an external device which is communicably connected with the attachment device, the data configured in the second communication format corresponding to the data configured in the first communication format based on the mapping information is acquired, and the data configured in the second communication format to the electronic device to control the one function of the electronic device to be performed is transmitted.

  • Patent number: 6959069
    Abstract: A method for testing a subscriber line of a PABX (Private Automatic Branch eXchange) using a DTMF (Dual-Tone Multi-Frequency) signal. The method includes the step of controlling a DTMF transmitter in response to a line test request from an exchange operator to transmit the DTMF signal to the subscriber line, the step of receiving a component of the transmitted DTMF signal reflected from the subscriber line due to impedance mismatching, and the step of determining from a strength of the received DTMF signal component whether the subscriber line is abnormal.

  • Patent number: 6480596
    Abstract: A direct inward-outward dialing (DIOD) trunk circuit having a DIOD detecting/sending circuit connected to tip and ring terminals connected to a central office line and a primary coil of a transformer, for detecting a polarity of the voltage potential at the tip and ring terminals and the current flowing therethrough to determine reception of one of an incoming and outgoing telephone call, and a switch, controlled by a relay driver responsive to an interface circuit used for interfacing the DIOD trunk circuit with a switching circuit of a private branch exchange (PBX), for enabling the current to flow between the tip and ring terminals through the DIOD detecting/sending circuit via one of a low or high impedance path, wherein the low impedance path is used to establish a speech path between a central office line subscriber and a corresponding extension subscriber of the PBX.

  • Patent number: 6345096
    Abstract: A central office line interface circuit commonly detects a status of a ring signal and a hook switch. The central office line interface circuit includes a hook switch connected to a telephone line, a ring signal path connected in parallel to the hook switch, and a detection circuit connected between a controller of the exchange and a node of the hook switch and the ring signal path, so as to detect a ring signal in an incoming call mode and to detect a hook off status in an outgoing call mode.

  • Patent number: 5930101
    Abstract: An over voltage cut-off circuit of a private branch exchange for cutting off the over voltage induced into an E&M (ear and mouth) tie line, includes an E ("ear") line over voltage cut-off circuit composed of an E arrestor which generates heat by the over voltage induced through the E port, and also of an E fuse which melts and blows if it surpasses a melting point. The circuit may also include an M ("mouth") line over voltage cut-off circuit.
