COMMUNICATION CONTROL EQUIPMENT

PURPOSE:To reduce a command execution processing and a line processing time and to improve line processing capability by providing a means scanning a processing request from each line, a means storing the processing request and a means reading the stored processing request and testing it. CONSTITUTION:In sending the processing request from line adaptors 10,10-1 to a line control section 4, a line address is sent from a line processing exclusive address control register 14 at a prescribed interval, given to the line adaptors 10,10-1 to scan the line processing request. When a line processing request exists in the line adaptors 10,10-1, the request is stored to the line processing request storage section 13 of a line control section 4 in advance at each line, microinstructions F, G are read and executed from a control storage section 2 to a microprocessor 1. The microinstruction F counts up a line address control register 3, gives it to the line processing request storage section 13 to given the processing request from the line to the microprocessor 1 and the line processing request is detected immediately by the next microinstruction G. Thus, the command execution processing time and the line processing time are reduced, the capacity of the control storage section is reduced and the line processing capability is improved.
