HUMAN MACHINE PROCESSOR DEVICE INTEGRATED WITH MAIN PROCESSOR BOARD AND INTERFACE MODULE IN TELEPHONE EXCHANGE AND CONTROL METHOD THEREOF

摘要

Higher for the invention cycle was mounted, simply incorporate the exchange-flight operator interface devices, and relates to a control method, in particular, RS232C interface board and a SCSI interface board in one of the interface module, the interface module integrally to the upper processor board relates to a processor board and the interface modules are integrated exchange flight operator interface device and a control method, according to the invention the top processor board and the interface modules are integrated exchange flight operator interface device and a control method by, RS232C interface board after integrating the SCSI interface board in one of the interface modules, the interface modules by setting a to mount a one-piece in the top processor board, with only one-half the size of the shelf operator interface device significantly reduced system implementation is the To not only decrease the cost of installation, by enabling interaction between the interface module and the higher processor board with a dual port RAM communication method, is not a separate need to VME bus and reduce the installation costs, thereby improving the data transfer rate because that there is a great effect.
