摘要： PURPOSE:To increase easily both the subject digits and the timer set time and to set finely the telephone charge time, by using the dial number data as the address data to give an access to a memory and setting the charge time based on the codes read out with the designation of an address. CONSTITUTION:A hook switch 101 transmits an output showing an off-hook state by the operation of a handset 20, and a start circuit 102 drives a GS relay 103 in response to the actuation of the switch 101. Thus a GS relay contact 104 is closed for the connection of a talking circuit 107 to line terminals LA and LB via polarity inversion detecting circuit 105, a diode bridge and a power unit 106. Then a DC loop is closed to a line to attain a call via the handset 20. A power unit 106 produces the local power supply voltage by means of a line current which has circulation in response to the closure of the DC loop and supplies this voltage to each part. Even in an on-hook mode, i.e., in an open mode of the DC loop, a current having such a degree that gives no actuation to an exchange is flowed via a high resistance (not shown here) via a loop shown by an arrow head A. Thus a capacitor is charged.

摘要： PURPOSE:To prevent a no-charge call by driving a call compulsory disconnecting circuit when the next charging signal is not received within a specified time during a timer operation. CONSTITUTION:A CPU 109 starts a charging check timer that is provided utilizing a prescribed memory area and confirms that an answer flag which shows the presence/absence of reception of a first charging signal (including a dummy signal) is set or not. And next, the CPU 109 starts a charging timer. This is to perform a terminal multi-charging after a second charge. Afterwards, by monitoring the end flag of the charging timer, the timer is restarted at every setting of the end flag and a process is moved to a containing process. On the other hand, when a timer time elapses without the setting of the answer flag, after the charge checking timer is started, the CPU 109 judges that the reception of the charging signal is prevented by some reason and completes a containing decision process by setting a hook flag and moves to a hook process and therefore prevents a no-charge call by disconnecting the call compulsorily.

摘要： PURPOSE: To keep high impedance regardless of line-voltage for an input impedance to a subscriber line by utilizing a control signal changing at a prescribed time constant so as to change gradually the line-voltage transmitted from a feeding circuit and using an electronic switch acting like an inductance equivalently so as to invert the polarity of the line-voltage.
CONSTITUTION: The line-voltage V changes gradually by a sole set of feeding circuit BN to which a control signal ctl generated by a low pass filter LPF2 is inputted and inverted by a polarity inverting circuit RV. Further, the input impedance viewed from the subscriber line SL is kept to a high impedance by the polarity inverting circuit RV. As a result, the number of feeding circuits BN is halved in comparison with that of a conventional subscriber circuit SLIC, a low pass filter LPF1 using a coil L and a capacitor C of large capacitance is not required, the subscriber circuit SLIC is miniaturized and high density mounting is attained.

摘要： PURPOSE:To attain long range transmission line by providing a repeater corresponding to a desk top PB telephone set in common use 100 yen coins and allowing the repeater to relay a 2-wire DC loop signal from an exchange so as to discriminate the propriety of a 100 yen coin deposition end signal and a DC loop signal. CONSTITUTION:The repeater REP is provided corresponding to the desk top PB public telephone set PSZ in common use of 100 yen coins, the REP is activated by a call of the telephone set PSZ and connected to an automatic exchange AX. The AX selects an outgoing trunk OGC by a central controller CM and connects the REP to a called subscriber. A trunk OGT transmits a DC loop signal to the REP via the AX in response to the called party. The DC loop signal is regenerated by the REP, transmitted to the telephone set PSZ so as to discriminate the 100 yen coin deposition end signal and the DC loop signal from the telephone set PSZ. The result of discrimination is transmitted to the AX by the DC loop signal so as to relieve the existence of a station impossible for allocation of the automatic exchange of the 2-wire DC loop system or long range transmission line.

摘要： PURPOSE:To attain ease of discrimination of mis-operation and incorrect operation by disabling transmission if a dial number is an inhibited number, cutting off a DC loop circuit when incorrect number to disable reception and transmitting an audible tone to a receiver. CONSTITUTION:A control section CNT judges the presence of a deposited coin in response to the detection output of a coin detection circuit CCD and when it is judged to be an inhibited number, restoration control is applied to a block relay TS only, a contact ts by-passes a transmitter T to disable the transmission. Further, when it is judged as an incorrect number, a switch SW is controlled to open a DC loop circuit forcibly for a prescribed time, the restoration control to the by-pass relay SS is attained, the transmission/reception by a contact (ss) is disabled, an oscillator OSC is controlled, an audible tone signal corresponding to a busy tone is generated and transmfitted to a receiver R of a talking circuit TKC. Thus, when the inhibited number is dialed, the transmission is disabled, and when an incorrect number is transmitted or a coin is stored incorrectly, an audible tone is listened to.
