Abstract

PURPOSE:To provide a circuit switchboard with a function of storage without the modification of a program and extension of a file, by providing an additional trunk at the same position with a subscriber. CONSTITUTION:When subscriber A is to make a telephone call to subscriber B and subscriber B is engaged, subscriber A calls storage trunk 3 by a specific dial number and sends information to be sent to subscriber B. Next, trunk 3 converts the information, a series signal, into a parallel signal by transmitting-receiving circuit 4 and processor 5 operating according to the contents of program memory 6, after storing the information in storage memory 7, disconnects subscriber A. This trunk 3 reads subscriber B a certain time later and sends the information stored in memory 7 to subscriber B when subscriber B is connected. Then, the circuit switchboard is provided with the storing function without the modification of the program, extension of a memory file, etc., by providing channel 1 with trunk 3.
