Abstract

교환기의 전용선 제어 방법에 관한 것으로, 특히 교환기간에 접속된 링다운 전용선을 이용하여 상대 교환기에 접속된 가입자을 집적호출하는 제어 방법에 관한 것이다.The present invention relates to a method of controlling a leased line of an exchange, and more particularly, to a control method of collectively calling a subscriber connected to a counterpart exchange using a ring-down leased line connected during an exchange.

상기의 전용선 제어방법은, 제1교환기(12)에 수용된 임의의 가입자가 훅크 오프시에 상기 임의의 가입자로 다이얼 톤을 공급하고, 전용선 억세스 코드를 다이얼링시에 휴지의 전용선을 억세스하여 상기 제1교환기(12)와 전용선으로 연결된 교환기(16)로 링신호를 송출하는 전용선 점유과정과, 링신호의 입력에 응답하여 상기 교환기(16)가 상기 임의의 가입자로 다이얼톤을 공급하고, 상기 전용선을 통해 수신되는 다이얼 디지트를 수신하여 상기 다이얼 톤의 송출을 차단함과 동시에 수신된 디지트의 피호자를 탐색하는 피호자 탐색과정과, 상기 피호자 탐색시 상기 교환기(16)가 상기 피호자로 링신호를 송출함과 동시에 상기 임의의 가입자로 링백톤을 송출하여 통화로를 형성하는 통화로 형성과정과, 상기 통화로가 형성된 임의의 가입자 및 상기 피호자들 중 하나의 가입자가 훅크 온시 상대편의 교환기로 링신호를 송출하며 통화로를 복구하는 과정으로 이루어진다.In the leased line control method, any subscriber housed in the first switch 12 supplies a dial tone to the random subscriber at the time of hooking off, and accesses the idle line at rest when dialing the leased line access code to access the first line. A leased line occupation process for sending a ring signal to the switch 16 connected to the switch 12 by a leased line, and in response to the input of the ring signal, the switch 16 supplies a dial tone to the random subscriber, Receiving a dial digit received through the block digit and blocking transmission of the dial tone, and searching for a protector of the received digit; and searching for the protector; And a call path forming process for sending a ringback tone to the subscriber at the same time to form a call path, and for any subscriber and the protector on which the call path is formed. One of the subscribers sends a ring signal to the far end of the hook switch turns on, and consists of a process for recovering the speech.

Claims

A switch 12 having a plurality of subscribers serving a call and having a ring-down dedicated line connected to a trunk line trunk circuit, and a switch 16 having a dedicated line of the switch 12 connected to a trunk circuit to perform a dedicated line call processing. In the dedicated line control method of the switching system, any subscriber accommodated in the switch 12 supplies a dial tone to the arbitrary subscriber at the time of hooking off, and accesses the idle line at rest when dialing the leased line access code. Occupying the leased line to send the ring signal to the switch 16, and in response to the input of the ring signal, the switch 16 supplies a dial tone to the subscriber, and receives a dial digit received through the leased line Blocking the transmission of the dial tone and simultaneously searching for the target of the received digit; The channel 16 sends a ring signal to the callee and simultaneously sends a ringback tone to the subscriber to form a call path, and any subscriber and the callees formed with the call path. When one of the subscribers is hooked on, the method comprising the step of transmitting a ring signal to the exchange of the other party to restore the communication path.
