摘要： PURPOSE:To allow data to arrive at an exchange for store and forward switching securely within a time, by previously allotting the starting time of transmission to a terminating terminal to the exchange from an originating terminal. CONSTITUTION:An originating terminal informs a store and forward switching exchange SFS that registration communication is to be performed, and of the number of a terminating terminal and incoming limit time, and then sends communication data. The SFS stores the communication data in a data storage memory DM, and registers other data in a registered communication registering memory RM; when the terminating terminal TTM is free, the transmission of the data is started immediately. When the data transmission is disallowed because the TTM is use, a CPU monitors the contents of the RM to check whether termination is possible or not at certain intervals of time up to the incoming limit time. When the TTM is use for general communication at the incoming limit time monitored through a timer TM, a circuit controller CMU disconnects the circuit and connects another circuit for the registration communication, which is performed forcibly.

摘要： PURPOSE:To reduce the burden of an operator, by automatically connecting to an extension telephone set by directly dialing an extension number, in case when a line wire telephone is a pushphone telephone set. CONSTITUTION:When a call from a line wire telephone set TEL1 comes in, a primate branch exchange PBX, at first, connects the TEL1 to a talkie return trunk TKT. Subsequently, from the TKT, such a voice as ''Pushphone's caller! Please push an extension number.'', etc., is returned to the TEL1, and immediately the TEL1 is connected to a push register trunk PBRT. When the TEL1 is a pushphone telephone set and its extension number is pushed, the TEL1 is connected to an extension telephone set without an operator's work. On the other hand, in case when the TEL1 is a dial telephone set, a pushphone signal is not received even after a constant interval of time has passed, therefore, after the constant interval of time has passed, the TEL1 is connected to an attendant board.

摘要： PURPOSE:To enable confidential service by providing a means of receiving a confidential signal and a receiver specifying signal and distributing and storing a recorded picture, and a means of fetching the recording picture in collating the receiver discrimination signal. CONSTITUTION:A picture signal containing a confidential service request signal and a receiver specifying signal is transmitted from a transmitting terminal. When the confidential service request signal discrimination part 23 of a discrimination part 2 receives a confidential service discrimination signal, a discrimination part 24 for the receiver specifying signal is actuated. The discrimination part 24 discriminates the receiver specifying signal to generate discrimination outputs D21-D23, thereby operating the guide boards 41-44 of a distribution part 4. A recorded picture reproduced by a reception part 3 is stored in a storage part 5 in accordance with the guide boards. When a receiver inputs a characteristic mnemonic number from the keyboard 58 of the storage part 5, a collation part 59 collates it to open fans 55-57 with locks of the storage part 5.
