AUTOMATIC CALLING UNIT CONTROL SYSTEM

摘要

In a data communications system where a plurality of line adapters connect to remote peripheral units there is provided a control system for controlling selected Automatic Calling Units which can dial connection lines to remote peripherals or systems. A microprocessor having output control registers can select specific line adapters having an ACU-output register. It can then load dialing-digit data and ON/OFF control data into the ACU-output register for controlling the associated Automatic Calling Unit.
