ACCUMULATION PROGRAM CONTROL ELECTRONIC EXCHANGE

摘要

PURPOSE:To cooperate a real time system such as a call processing function and a non-real time system such as a UNIX function by adding said UNIX function to a processor having the call processing function. CONSTITUTION:A call control part 12 classifies terminal information transmitted from a communication control part 9 into UNIX service information and call processing information other than former information. The call control part 12 executes activating and stopping UNIX services or judges the transfer of information. When an activation request or a stop one is issued, the control part 12 activates a UNIX service control part 13-1. When the transfer request of information to the UNIX function 11 is issued from the side of the communication control part 9, the information is reported to a transmission control part 13-2 through the call control part 12. The transmission control part 13-2 writes information on a communication file having been already opened. The side of the UNIX function 11 reads out information from the opened communication file with an FIFO constitution.
