摘要： PURPOSE:To easily connect an independent telephone set with a trunk line which constitutes a bus line by providing a communication loop detecting line for both a key telephone set and the independent telephone set, and discriminating a communication by the key telephone set from the commuication by the independent telephone set, by the presence or absence of a data commond. CONSTITUTION:When an independent telephone set 14 captures the trunk line, a communication loop detecting circuit 17 in a main device 16 is turned to be in an ON state. A control circuit 18 identifies the trunk line capture of the independent telephone set 14 when a trunk line capture command is not supplied from a data I/F circuit 19 after the lapse of a constant time since a loop detecting signal is supplied, and transmits the trunk line capture command to each key telephone set 12. Moreover, the loop detecting signal is supplied to the control circuit 18 in the same way at the time of responding again to a hold, so that a relay 20 can be operated, and a holding circuit 21 can be turned to be in an OFF state. Thus, the independent telephone set 14 can be easily connected with the trunk line which constitutes a bus line 11.

摘要： PURPOSE:To display a speech charge irrespective of the type of a telephone set by recognizing the timing of a speech start and a transmission dial number irrespective of the type of the telephone set, calculating the speech charge based thereon and transmitting the calculated result to a key telephone system. CONSTITUTION:The telephone number or the like of himself is previously registered by the use of a ten key 10. A speed start timing detecting circuit 3 detects the capture of a trunk line 1 by raising the receiver of a key telephone set. A CPU 4 calculates the speech charge based on a self-telephone number registered by the ten key 10 and the transmission dial number obtained from a PB signal detecting circuit 6, transmits a displaying signal corresponding to the calculated result to an LCD driver 8 and displays the speech charge. The calculated result of the speech charge is transmitted to the key telephone set as a data command through a data interface circuit part 11 by the CPU 4 and the speech charge is displayed on the display device of this key telephone set.

摘要： PURPOSE:To attain the reproduction and stop operations of a cassette tape recorder through each terminal unit by providing a control unit to a loudspeaking slave device for control of an interphone master device. CONSTITUTION:An interphone master device 1 with BGM incorporates a cassette tape recorder, a radio set and a loudspeaking amplifier for terminal unit and connects them to each terminal via wirings L1-L6. The L1 and L4 serve as power supply lines, and the L2 transmits a 13-bit control signal through each terminal for control of the cassette tape recorder and the radio set of the device 1. The L4 performs the talking through an interphone, and the L5 delivers the BGM broadcast delivered between the L4 and L5. Then the L6 delivers with loudspeaking the sound broadcast to the L4 and L6 from the device 1. A terminal unit 3 of a loudspeaking slave device has switches S1-S4 for reproduction, rewind, fast forward and ON/OFF of the radio set respectively. A control unit 4 of each terminal unit converts the signals sent from switches S1-S4 into the 13-bit signals and sends them to a call line of the L2.

摘要： PURPOSE:To restore the runaway of a CPU even if it takes place by devising the device such that the storage content of a data group RAM is not cleared by the reset of the CPU applied simultaneously with the acquisition of a telephone line. CONSTITUTION:The data system RAM of a dial CPU 1 is provided with a 1st reset means initializing a program stored in a control system RAM storing the memory content and a 2nd reset means short-circuiting the power supply Vcc of the CPU 1 and the GND, initializing a data system RAM and a control system RAM of the CPU 1 to clear the storage content entirely when the manual switch 6 is forcibly depressed manually. Thus, every time a trunk line is acquired at talking, only the content of the data system RAM of the dial CPU 1 to be built in is cleared by the 1st reset means but the storage content of the control system RAM is left. Even if runaway of the CPU 1 takes place, the CPU is restored without fail.

摘要： PURPOSE:To connect a single telephone set, a facsimile, an automatic answering telephone set or the like to a central office line with a simple constitution by connecting the terminal of the facsimile or the like to the central office line of the push button telephone set in a main device through a relay turned off during the use of the push button telephone set. CONSTITUTION:Under an ordinary state, relay contacts 10, 11 are turned on, and the terminals 2, 3 are operated to capture the central office lines L1, L2. At the time of capturing the central office lines, a current passes to detecting means 6, 7 from the central office lines L1, L2 and it is detected in the detecting means 6, 7. The detecting information is transmitted to the push button telephone sets 4, 5 by the microprocessor 12 of the main device 1 and displayed. At the same time, the central office lines L1, L2 cannot be captured by the push button telephone sets 4, 5. At the time of operating the push button telephone sets 4, 5 and capturing the central office lines L1, L2 under the ordinary state, the information is transmitted to the microprocessor 12 from the telephone sets 4, 5 to operate the relays 8, 9. Accordingly, the relay contacts 10, 11 are turned off, the terminals 2, 3 are separated from the central office lines L1, L2 and the central office line in the terminals 2, 3 cannot be captured.

摘要： PURPOSE:To reduce the automatic reporting device in size and weight and improve its reliability by writing sounding information in semiconductor memory and transmitting information read out of the semiconductor memory according to report contents or contents set with external keys. CONSTITUTION:When some of sensors D1-Dn operates, a sensor monitoring part Sen receives its output and sends information on it to a control unit CON. The control unit CON actuates a speech synthesizing circuit VO and also supplies an actuation signal to the control unit NCU. Information from ROM is converted into a speech signal through a digital filter DF, D/A converter D/A, and analog filter F and sent out to a telephone circuit B through a network control unit NCU. Information characteristic to a user is sent out according to the contents of the ROM by setting an access counter AC with a key Key.

摘要： PURPOSE:To stop hearing of BGM (background music) broadcasting and hear general broadcasting in this state, by operating a changeover switch to transmit BGM broadcasting and general broadcasting through one transmission line and both transmission lines respectively. CONSTITUTION:Changeover switches 3a and 3b are provided in the transmission side, and the switch 3a switches signals of a BGM broadcasting sound source 1 and a mike 2 for general broadcasting to transmit them to a transmission line 5. When the signal of the mike 2 is transmitted to the transmission line 5 by transmitting the switch 3b with the switch 3a the signal transmitted to the other transmission line 6 also. A changeover switch 7 in the reception side switches optionally signals of transmission lines 5 and 6 and impresses them to a common speaker 8. Consequently, when an audience does not want to listen to BGM broadcasting, he switches the switch 7 to stop hearing and can listen to general broadcasting in this state.
