Abstract

본 발명온 사설교환기의 자동 재다이얼링 방법에 관한 것으로, 사설교환기측 비밀번호를 알고 있는 사용자가 사설교환기의 임의 국선을 통하여 전화를 건 다음 호출을 원하는 사용자의 전화번호를 다이얼링하면 사설교환기 에서는 이를 인지하여 비밀 번호를 확인한 후 다른 임의 국선을 점유하여 자동재다이얼링을 수행시키고 자동재다이얼링이 실시된 국선과 외부 사용자가 다이얼링한 국선을 연결시켜 통화가능케 함으로써 외부사용자가 사설교환기 국선을 효율적으로 이용하여 외부통화할 수 있게 한 방법이다.The present invention relates to a method for automatic redialing of a private exchange. When a user who knows a private exchange side password makes a call through a private trunk line of a private exchange, dials a telephone number of a user who wants to make a call, the private exchange recognizes this. After confirming the password, the automatic user redials by taking the other arbitrary CO line and connects the CO line with the automatic redial and the dialed CO line to the external user so that the external user can make effective use of the private line. It's a way to do it.

Claims (3)

사설교환기의 자동 재다이얼링방법에 있어서, 국선(A, B)간의 통화를 가능케하는 통화로 연결부(4)와, 다이얼신호 감지부(2)를 제어하여 상기 국선(A)로 입력되는 다이얼신호를 읽어들이고 이를 메모리부(7)에 저장 및 분석하는 제어부(6)와, 제어부(6)의 명령에 따라 다이얼신호감지부(2)에서 감지된 다이얼 신호를 국선 B를 통하여 자동재다이얼링 송출하는 다이얼발생부(8)를 구비하여 상기 국선(A)를 통하여 다이얼링 실시한 외부 사용자로 하여금 상기 국선(B)를 통하여 외부통화가능토록하는 사설교환기의 자동재다이얼링방법.In the automatic redialing method of a private exchange, a dial signal input to the trunk line A is controlled by controlling a connection part 4 and a dial signal detection unit 2 that enable a call between trunk lines A and B. A dial 6 for reading and storing and analyzing the same in the memory unit 7 and a dial signal detected by the dial signal detecting unit 2 according to a command of the controller 6 and automatically redialing and transmitting the signals through the trunk line B. FIG. A method for automatic redialing of a private exchange having a generation unit (8) to allow an external user who dials through the trunk line (A) to make an external call through the trunk line (B). 제1항에 있어서, 상기 제어부(6)에 의한 제어명령은 상기 국선(A)로 착신되는 다이얼신호가 있으면(10), 이를 확인하는 다이얼톤을 송출하고(11) , 다이얼 신호 감지부(2)를 제어하여(12) 입력되는 다이얼신호가 있는지 판단하여(13) 다이얼신호입력이 있으면 메모리부(7)에 이를 저장하고(14) 소정순위에 입력된 다이얼링이 있은 후 일정시간이 경과해도 다이얼링 입력이 없으면(15), 다이얼링 완료된 것으로 확인하여 저장된 다이얼신호를 분석(16)하는 과정과, 다이얼신호 분석결과 사설교환기측 사용 비밀번호와 일치하는 것으로 판단되면(17), 국선(B)를 점유하여 자동재다이얼링 루틴(18)을 수행하는 과정과, 다이얼신호 분석결과 사설교환기측 사용 비밀번호와 일치하지 않는다면(17), 국선(A)로 에러톤을 송출하고 (25), 국선(A)를 끊는 과정(27)으로 이루어 지는 것을 특징으로 하는 사설교환기의 자동재다이얼링 방법.According to claim 1, wherein the control command by the control unit (6), if there is a dial signal incoming to the trunk line (A) (10), and transmits a dial tone to confirm this (11), dial signal detection unit (2) (12) determine whether there is a dial signal input (13), if there is a dial signal input, store it in the memory unit (14), and dialing even after a certain time has elapsed after the dialing has been input in a predetermined order. If there is no input (15), the process of verifying that dialing is completed and analyzing the stored dial signal (16), and if it is determined that the dial signal analysis result matches the private exchange side use password (17), occupies the trunk line (B) If the process of performing the automatic redialing routine 18 and the dial signal analysis result do not coincide with the password of the private exchange side (17), an error tone is sent to the trunk line (A) (25) and the trunk line (A) is disconnected. The process (27) Automatic re-dialing method that features a PABX. 제2항에 있어서, 상기 자동 재다이얼링 루틴(18)은 국선(B)를 점유하고(19) 톤 감지부(9)를 통하여 발신음을 확인한 다음(20) 기억된 다이얼신호를 송출하는 과정(21)과, 다이얼링실시후 통화중음이 인식되면(22) 국선 B를 끊고(23) 소정시간동안 대기한 다음(24) 다시 국선(B) 점유모드로 돌아가는 과정과, 다이얼링 실시후 통화 가능음이 인식되면(22) 국선(A, B)간의 통화로를 연결하는 과정(27)으로 이루어 진 것을 특징으로 하는 사설교환기의 자동 재다이얼링 방법.The process of claim 2, wherein the automatic redialing routine (18) occupies the trunk line (B), checks the dial tone through the tone detector 9 (20), and then transmits the stored dial signal (21). ), If the busy tone is recognized after dialing (22), disconnect the CO line (23), wait for a predetermined time (24), return to the CO line (B) occupancy mode, and recognize the available sound after dialing.
