摘要： PURPOSE:To decrease the capacity of the memory part and thus to miniaturize the overall structure as well as to realize the cost reduction by installing the check bit generation circuit within the decoder. CONSTITUTION:The specified receiver is called out by transmitting the individual number code formed with the information bit and the check bit. The receiver includes memory part 16 to memorize only the information bit, check bit generation circuit 15 to generate the check bit based on the information bit and decoder 14 each. Decoder 14 gives comparison to the received individual number code plus the information and check bits given from memory part 16 and circuit 15. As a result, the capacity of the memory part can be decreased to miniaturize the overall structure, thus realizing the cost reduction.

摘要： PURPOSE:To make an accurate hooking operation possible, by setting properly the difference between the loop switch-off time of a wire terminal equipment and the hook switch-on time of a telephone set, which is generated by the difference between the disconnecting operation time and the connecting operation time, to approximate zero. CONSTITUTION:By hook-off of a hook switch 16, a transmitter 11 and a control signal oscillator 7 are operated by a logical controlling circuit 15, and modulated radio waves of a control signal f1 are transmitted from an antenna 13. In the wire terminal equipment side, these radio waves are received, and a detection signal f1' from a control signal detector 29 is led to a logical controlling circuit 30. The circuit 30, a transmitter 22, and a control signal oscillator 28 are operated by this signal, and modulated radio waves of a control signal f2 are transmitted from an antenna 20. Thereafter, dial information is sent to the wire terminal equipment through a controlling circuit 6 and an oscillator 7 by the operation of a dial 5. This control signal is detected by a detector 29, and a loop switch 33 is controlled through the circuit 30 to send dial information to a wire transmission line 31. Thus, the service is permitted after switching connection and response the called subscriber.

摘要： PURPOSE:To achieve re-dialing or repertory dialing easily, by setting a specified transmission pause time with a timer, when a private branch of exchanger makes trunk line catching. CONSTITUTION:When a handset is hooked on, a hook switch 11 is operated and the 1st digit detection circuit 12 is set. When a caller operates a dial key pad 13 and inputs a dial number, the dial information is applied to a control circuit 14 and written in the re-dialing address in a memory 15, and a dial signal is transmitted from a dial oscillation circuit 16. After the 1st digit figure, a special information is written in and the figures on and after the 2nd digit are stored in the memory 15. When a re-dial button 17 is depressed at re-dialing because of busy opposing party, re-dialing information is read out from the memory 15, and when the specific information is detected at a detection circuit 20, a timer 18 is operated and the transmission of dial is paused for 2 seconds.

摘要： PURPOSE:To let a user know incoming with regard to radio-coupled detephone stes, by providing incoming display at a base station in case that even after an incoming signal is sent to a mobile telephone set in response to the incoming, no answer is made. CONSTITUTION:On detecting incoming signal (a), base station 3 sends incoming signal (d) out to moible telephone set 6. Answer signal (i) is not received in case that telephone set 6 can be answer because of installation in an electric field of weak reception intensity, etc. If answer signal (i) is not detected for a fixed period, no-answer detecting circuit 15 sends signal (g) out and drives incoming display unit 16 at the side of base station unit 3.
