KR950023074A - Attendant console interface device and its operation method of medium capacity private exchange - Google Patents

Abstract

The present invention relates to an assistant console interface device of a medium-capacity private exchange for an integrated information communication network, and a method of operating the circuit, which implements the interface between the attendant console and the exchange system so as to relay and process information between the personal computer for the attendant console and the exchange. By applying the IEEE-488 standard interface to the interface for the attendant console of the switch of the general information communication network, a high-speed data transfer in bytes is realized. The three-wire handshake method, which is characteristic of the standard bus, hardly allows errors in the data being transmitted, so a large amount of information is transmitted quickly and accurately. The system should be able to extract and store data or take appropriate measures when an error occurs while monitoring and improving various system related information such as system status check, billing information, call status time information, extension number allocation status, self-diagnosis information, etc. This interface circuit meets these requirements.
