Abstract

본 발명은 자동전화교환기에서의 우선순위 통화방법에 관한 것으로, 복수의 전화회선(가입자회선)에 대한 통화선로를 자동으로 접속시키는 자동전화교환기에서, 외부로부터 임의의 부서에 대해 통화호출이 있게 되면 그 호출된 전화번호를 일시저장시킨 후 해당 전화번호에 대한 통화중상태를 판단하는 제1단계와; 상기 판단결과 비통화상태이면 해당 전화번호에 대한 통화개시동작을 수행시키는 반면, 통화중이면 인터럽트를 발생시켜 동일 부서내의 최우선순위의 전화번호를 독취하여 통화중상태를 판단하는 제2단계 및 ; 상기 판단결과 현재 독취된 최우선순위의 전화번호가 비통화상태이면 상기 일시저장된 현재의 전화번호를 상기 독취된 전화번호로 갱신시킨 수 통화개시동작을 수행시키는 반면, 현재 독취된 최우선순위의 전화번호가 통화상태이면 재차 인터럽트를 발생시켜 후속하는 우선순위의 전화번호에 대한 통화중상태를 판단하고서 그 판단결과에 따라 상기 통화개시동작 또는 상기 인터럽트 발생에 의한 후속하는 우선순위의 전화번호에 대한 통화중상태 판단동작을 반복하는 제3단계로 구성되어, 번거롭게 재차 전화를 걸어야 되는 불편함을 제거하는 효과가 있게 된다.The present invention relates to a priority calling method in an automatic telephone exchange, wherein in an automatic telephone exchanger which automatically connects telephone lines to a plurality of telephone lines (subscriber lines), when a call is made to an arbitrary department from the outside, A first step of temporarily storing the called telephone number and determining a busy state of the telephone number; A second step of determining a busy state by reading a telephone number of the highest priority in the same department by generating an interrupt when the call is in progress while performing a call initiation operation for the corresponding telephone number if the call is in a non-call state; If the phone number of the currently read highest priority is in a non-call state, the determination result is to perform a call initiation operation of updating the temporarily stored current phone number with the read phone number, while the currently read highest priority phone number is executed. If it is in a call state, an interrupt is generated again to determine a busy state for a subsequent priority telephone number, and according to the determination result, the call initiation operation or a busy state for a subsequent priority telephone number due to the interrupt occurrence. It is composed of a third step of repeating the determination operation, there is an effect of eliminating the inconvenience of having to make a phone call again.

Claims

In an automatic telephone exchanger that automatically connects telephone lines to a plurality of telephone lines (subscriber lines), when a call is made to any department from the outside, the telephone number is temporarily stored and then the telephone number is stored. A first step of determining a busy state; A second step of determining a busy state by reading a phone number of the highest priority in the same department by generating an interrupt when a call is made while performing a call initiation operation for the corresponding phone number if the call is not in a call. If it is determined that the currently read highest priority phone number is in a non-call state, the phone call operation of updating the temporarily stored current phone number to the read phone number is performed while the currently read highest priority phone number is called. If so, an interrupt is generated again to determine the busy state for the next priority telephone number, and according to the determination result, the call initiation operation or the load for the subsequent priority telephone number due to the intervert occurrence. Priority in an automatic telephone exchange comprising a third step of repeating the status determination operation How angry.
