Abstract

PURPOSE:To offer complete circuit reservation service and to send originating signals from telephone sets by operating external circuit selection buttons of telephone sets and by storing reservation information when the external circuit is engaged while sending signals from dey telephone sets when not. CONSTITUTION:Main control unit MCU has a processor and office units SLU1- SLUm that have processors as well are provided with the functions of connecting with the external circuit. Further, terminal units TEU1-TEUn with processors are connected to key telephone sets MFT1-MFTn through voice circuits VL1-VLn and data circuits DL1-DLn. After external circuit selection buttons of telephone sets MFT1-MFTn that are not shown in the figure are operated, reservation information is stored when the external circuit is engaged and signals are sent out from telephone sets MFT1-MFTn when the external circuit is disengaged. Consequently, the perfect circuit reservation service can be offered and signals can be sent from the telephone sets.
