摘要： PURPOSE:To attain versatile voice messages with having only to replace external storage cards one after another by storing a voice message on an external storage card. CONSTITUTION:A function menu and a message number stored in a telephone set main body or on an external storage card 6 are stored in a telephone set mount content storage circuit 14 and a card mount content storage circuit 16. Moreover, a voice message edit data and a synthesized voice data stored in the telephone set main body or the external storage card 6 are stored in a telephone set voice message parameter storage circuit 15 and a card voice message parameter storage circuit 17 respectively. Since the voice message is stored on the external storage card 6 in this way, the versatile voice messages are provided by having only to replace external storage cards 6 one after another.

摘要： PURPOSE:To improve the rate of recording of caller information by completing the automatic answering operation while recording a caller voice in natural conversation. CONSTITUTION:The telephone set consists of a connection terminal 1, a loop open/close means 2, an incoming call detection means 3, a line interface section 4, a recording/reproducing means 5, a reply message storage means 6, a message storage means 7, a signal level detection, means 8, a voiced tone discrimination means 9, a time count means 10, a voice time parameter storage means 11, a silence time parameter storage means 12, and a control means 13. Then four reply messages comprising three basic messages usually used by a called party at the normal telephone reply and a basic message required in the message recording of the automatic answering telephone set are prepared and each reply message is sent based on the presence of the voice of a caller and the timewise length of the voice to complete the automatic answering operation while recording the caller voice in the natural conversation. Thus, the rate of recording of caller information is improved.

摘要： PURPOSE:To prevent a talking from being interrupted regardless of absence of the intention of end of talking by a slave set operator by allowing a master set to operate for a prescribed line a holding line and keeping to acquire the telephone line even if a pilot signal from the slave set is interrupted during talking. CONSTITUTION:If the master set 2 cannot receive a pilot signal and a carrier because of a slave set going at the outside of a radio wave arrival zone or voltage decrease in the battery or radio wave interference disturbance or the like, a control section 38 operates a timer 39 to activate a retention circuit 40 to keep the telephone line 5 in the holding state and sends the holding tone to a telephone line 5. A slave set operator recognizes the disabled talking by an external speaker 3, then the control section 38 of the master set 2 resets a timer 30 and to inactivate the holding circuit 40 to make the telephone line 5 into the talking state while the slave set comes back again within the radio wave arrival zone or the interference/disturbance of radio wave is stopped after time elapses.

摘要： PURPOSE:To eliminate an AC power source and to contrive the reduction of the power consumption of a communication terminal by charging a capacitor with a call signal current supplied from an exchange and rendering the accumulated energy to drive a switching means having a self-holding function. CONSTITUTION:When the call signal current is inputted from a terminal 12, it charges the capacitor in a charging circuit 11 and is accumulated as energy. A signal corresponding to a call signal is inputted to an incoming call state detection circuit 5. After a prescribed time passes, a control circuit 7 activates a latching relay driving circuit 10 due to an output from the incoming call state detection circuit 5. The latching relay driving circuit 10 uses a part of the energy accumulated in the capacitor to operate a latching relay 8 to a set state, and closes a DC loop between the exchange and the titled device with the aid of a movable contact point 9. without using the AC power source, the DC loop can be automatically closed between the exchange and the communication terminal.

摘要： PURPOSE:To increase the number of connectable registers without increasing the number of address buses by sending data in time division via a data bus to select the register to store the data sent next according to the combination of data and sending the data to the register for storage. CONSTITUTION:An upper decoder 5 selects an high-order register 8 by the value of an high-order address bus 3 and the data on a data bus 2 is put into the register 8. An intermediate decoder 7 selects an intermediate register 9 by the address value of the next address period and puts the 2nd data into the register 9. These data values are sent to the low-order decoders 13 and 14. A key decoder 6 is selected in the next address period and the contents of the register 8 are decoded and matched with the values of both decoders 13 and 14 for selection of a low-order register 10 or 11. Then the data on the bus 2 is stored in the selected low-order register.

摘要： PURPOSE:To obtain the high-precision D/A converter which does not depend upon the precision of a reference voltage by deriving an analog signal from the collector ratio of a couple of transistors (TR) which form a differential amplifier. CONSTITUTION:Plates of the TRs 12a and 12b forming the differential amplifier 13 are connected to output terminals of operational amplifiers 9a and 9b equipped with diodes 10a and 10b. A reference voltage Vref from a reference voltage source 8 is connected to plus terminals of the amplifiers 9a and 9b and a terminal 2 of a variable resistance network 7. The output terminal 4 of this network 1 is connected to the minus terminal of the amplifier 10 and a reference resistance 11 is connected to the minus terminal of the amplifier 10b. Then, the analog signal is led out on the basis of the ratio Ia/Ib of collector currents of the TRs 12a and 12b. This current ratio Ia/Ib does not depend upon the reference voltage Vref. Thus, the high-precision D/A converter which does not depend upon the reference voltage is obtained.

摘要： PURPOSE:To prevent erroneous redialing, by detecting a backup power supply voltage, and inhibiting redialing operation when the detected voltage is less than a specific value. CONSTITUTION:When the charging voltage of a backup power source BUP is greater than a specific value, the output of a gate circuit G is at a low level and a transistor (TR) Q3 turns off. Therefore, when a dial key KRD is turned on after off-hook operation, a redialing signal RD is outputted from a TRQ2. On the other hand, when the voltage of the power source BUP is less than the specific value, the output of the gate circuit G is at a high level and the TRQ3 turns on. In this case, the TRQ2 is still off even when the key KRD is turned on, so no redialing signal RD is outputted. Further, the light emission of a light emitting diode LED is maintained to provide visible display for showing whether redialing is possible or not when the key KRD is turned on.
