KR930011554A - Management method and circuit of station and trunk line status of private switching center - Google Patents

Abstract

In the trunk line and extension management method in the relay station of the private exchange, the first process of taking the event processing when the event buffer is not occupied and checking the communication port, the keyboard, the screen output, the file lead / light event, the input / output event recognition A second process of processing a communication port event coordination message, and a second process of resetting an extension display range corresponding to each screen moving key and stacking the state of the extension number in a buffer when the keyboard event is displayed; Process and check whether the screen output event date and time and the CO line related to update the CO line status on the CO line related date and time screen, update the file, and check the output range when the extension is related. Update and update the third process and the status of the file update request date and time at the file lead / write event. And a fifth process of checking a file read request temporary reset range and outputting a corresponding number state to a buffer; How to manage trunk line status.

In the trunk line and extension management method of the private exchange in the relay station, the first process of taking the event processing when the event buffer is not occupied to check the communication port, keyboard, screen output, file lead / ride event, I / O event recognition; And a second process of processing the communication port event coordination message, resetting an extension display range corresponding to each screen moving key when the keyboard event is required, and requesting the state of the extension number to be stored in a buffer and displaying the same on the screen. Step 2, check the screen output event date and time and whether or not the CO line related to update the CO line status on the CO line related date and time, update the file, and check the output range when the station is connected, if the number is being displayed on the screen to display the resistance status of the screen And update the third step and the file update request date and time corresponding to the file number when the file read / write event is performed. And a fifth process of checking a file read request temporary reset range and outputting a corresponding number state to a buffer, and a fifth process of stacking received data in an event buffer for the input / output event. And trunk line status management method. In the trunk line and station management circuit at the relay station of the private exchange, the level is converted to RS-232 transmission to be transmitted to the terminal for inputting and outputting data from the terminal directly to the internal circuit of the private exchange and transmitted to the extension circuit. And a direct terminal interface circuit (DT1) for converting into a 2-wire tries lever for keying, and connecting a personal computer (305) from the direct terminal interface circuit (DT1) to manage station and trunk line status. Circuit. ※ Note: The disclosure is based on the initial application.
