    Abstract: Free calling from a coin operated subset is provided by the circuitry which allows contingent counting of dialled digits up to a certain number and if said counting is completed preventing the dialling of further digits. If a coin has been deposited the completion of the counting is prevented and optional completion of the counting is prevented on the dialling of certain digits indicative of otherwise free calls such as service calls.

    Abstract: Special services, such as call transfer and abbreviated dialing, are provided by auxiliary circuits each uniquely associated with certain subscriber lines in a common control-switching system. The auxiliary circuit is arranged with shift registers to recognize the dialing of a predetermined code and to respond thereto by releasing and reenabling the common control switching equipment. On abbreviated dialing calls, the return of dial tone by the reenabled central office register enables the auxiliary circuit to outpulse the directory number of the desired station. On transfer calls, after dialing the access code, the subscriber primes the transfer feature by dialing the directory number of the transfer station. This number is then simultaneously stored in the auxiliary circuit and in the reenabled central office register. In either situation the call then progresses to completion in the normal manner.

    Abstract: In order to prevent the unauthorized use of dial-type telephones to make long distance calls, the security device of the present invention is fitted to the outer case of a standard desk or walltype telephone instrument. In position, it permits the dialing of up to, say, eight digits, and then prevents the dialing of any further digits until the telephone handpiece has been replaced and removed. The number of digits permitted will depend upon the type of installation, eight digits being used in a PABX: in a PABX a long distance direct dialed call requires the dialing of 9-1-and seven digits, i.e. nine digits in all, and any attempted call is aborted in the absence of the last digit. A lug on the rotatable dial mechanically sets a stop after eight dialings, which stop then engages the lug to prevent the ninth dialing.

    Abstract: A mobile phone (10) includes a touch panel (38) and a touch control circuit (36) detecting a touch operation, and can set a lock state that a telephone function or the like is restricted. If the lock state is set and a key operation is performed, a message urging to long-depress a touch is displayed on a display (30), and when the touch is detected, a changing object representing an elapse of time is displayed on the display (30). If five (5) seconds elapse in a touched state, a completion image is displayed on the display (30). Then, if a finger is released from the touch panel (38) within three (3) seconds after the completion image is displayed, the lock state is canceled.
