Abstract

PURPOSE: An in-band signal output method for a toll exchange is provided to offer a method for outputting the in-band signal, thereby capable of using the toll exchange in the region using the in-band. CONSTITUTION: In an incoming call, a wait state is maintained(step 10). An occupation signal is output during a predetermined time(200ms)(step 11). If there is a response during a predetermined time(195ms)(step 12), it is recognized as a subscriber free and then a ring request signal is output during a predetermined time(200ms) as an arbitrary interval(100ms)(step 13). If a signal is inputted during a predetermined time(200ms) with a predetermined interval(100ms), it is recognized as a subscriber's busy and then the connection is finished(step 14). After maintaining a signal input during a predetermined time as a response(step 15), if a signal input is maintained during a predetermined time(200ms) with an arbitrary interval(100ms)(step 16), it is recognized as a clear back according to the subscriber's free control and then a cancel detection signal is output till over the predetermined time(550-850ms)(step 17). If there is a signal input during a predetermined time(650ms), a relay operation is cancelled(step 18).

도 2는 본 발명에 따른 일실시예의 입중계 동작을 보인 신호 흐름도.Figure 2 is a signal flow diagram showing the incoming operation of an embodiment according to the present invention.

이와 같은 목적을 달성하기 위한 본 발명 톨 교환기용 인-밴드 신호 출력방법은 대기상태를 유지하다 소정의 인식시간 동안 톤의 입력이 유지되는가에 따라 소정시간 동안 점유신호를 출력한 후, 임의의 간격으로 소정시간 동안 신호 입력이 유지되면 다이얼링 신호로 인식하여 이 신호를 출력한 다음, 이에 따라 응답 및 응답제어신호가 입력되고, 임의의 간격으로 소정시간 동안 신호 입력이 유지되면 클리어 백(clear back)으로 인식하여 연결 해제를 위해 소정시간 이상까지 해제 검출신호를 출력한 후, 소정시간 동안 신호입력이 있으면 중계동작을 해제하는 출중계단계와;The in-band signal output method for the toll exchange of the present invention for achieving the above object maintains the standby state, after outputting the occupancy signal for a predetermined time depending on whether the input of the tone is maintained for a predetermined recognition time, If a signal input is maintained for a predetermined time, the signal is recognized as a dialing signal and the signal is outputted. Then, a response and response control signal are input accordingly, and if a signal input is maintained for a predetermined time at a predetermined interval, the signal is clear back. An outgoing relaying step of outputting a release detection signal for a predetermined time or more for recognizing a connection, and releasing the relay operation if there is a signal input for a predetermined time;

대기상태를 유지하다 소정시간 동안 점유신호를 출력한 후, 소정시간 이상 동안 응답이 있으면 가입자 프리(free)로 인식하여 임의의 간격으로 소정시간 동안 링 요구신호를 출력하며, 이후 응답으로 소정시간 동안 신호 입력이 유지된 후 임의의 간격으로 소정시간 동안 신호 입력이 유지되면 가입자 프리제어에 따른 클리어 백으로 인식하여 연결 해제를 위해 소정시간 이상까지 해제 검출신호를 출력한 후, 소정시간 동안 신호입력이 있으면 중계동작을 해제하는 입중계단계로 이루어진 것을 특징으로 한다.Maintain standby state After outputting occupancy signal for a predetermined time, if there is a response for a predetermined time or longer, the subscriber is recognized as free and a ring request signal is output for a predetermined time at a predetermined interval. If the signal input is maintained for a predetermined time at a predetermined interval after the signal input is maintained, it is recognized as a clear back according to subscriber pre-control and outputs a release detection signal for a predetermined time or more for disconnection, and then the signal input is continued for a predetermined time. If it is characterized in that it consists of an incoming relay step of releasing the relay operation.

이하, 본 발명에 따른 일실시예의 동작 과정을 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, an operation process of an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

본 발명에서 중계 동작을 크게 출중계 동작과 입중계 동작으로 나누어 설명하면, 첫 번째 출중계 동작은 도 1에 도시한 바와 같이 대기상태를 유지하다(step 1) 소정의 인식시간 동안(100 ~ 150ms) 신호 '1'의 입력이 유지되면(step 2) 소정시간 동안(200ms) 점유신호를 출력한 후(step 3), 임의의 간격(31 ~ 103ms)으로 소정시간 동안(40 ~ 46ms) 신호 입력이 유지되면 다이얼링 신호로 인식하여 이 신호를 출력한다(step 4).In the present invention, when the relay operation is largely divided into the outgoing operation and the incoming operation, the first outgoing operation maintains the standby state as shown in FIG. 1 (step 1) for a predetermined recognition time (100 to 150 ms). ) If the input of signal '1' is maintained (step 2), the occupancy signal is output for a predetermined time (200ms) (step 3), and then the signal is input for a predetermined time (40 to 46ms) at an arbitrary interval (31 to 103ms). If is maintained, it is recognized as a dialing signal and the signal is output (step 4).

이후, 소정시간 동안(200ms) 응답신호가 입력되고(step 5), 임의의 간격(100ms)으로 소정시간 동안(200ms) 응답제어신호가 입력된 다음(step 6), 임의의 간격(100ms)으로 소정시간 동안(200ms) 신호 입력이 유지되면(step 7) 클리어 백(clear back)으로 인식하여 연결 해제를 위해 소정시간(550 ~ 850ms) 이상까지 해제 검출신호를 출력한 후(step 8), 소정시간(650ms) 이상 신호입력이 있으면 중계동작을 해제한다(step 9).Thereafter, a response signal is input for a predetermined time (200 ms) (step 5), a response control signal is input for a predetermined time (200 ms) at a predetermined interval (100 ms) (step 6), and then at an arbitrary interval (100 ms). If the signal input is maintained for a predetermined time (200ms) (step 7), it is recognized as a clear back and the release detection signal is output until the predetermined time (550 to 850ms) or more for disconnection (step 8). If there is signal input for more than 650ms, the relay operation is canceled (step 9).

두 번째로 입중계 동작은 도 2에 도시한 바와 같이 대기상태를 유지하다(step 10) 소정시간 동안(200ms) 점유신호를 출력한 후(step 11), 소정시간(195ms) 이상 동안 응답이 있으면(step 12), 가입자 프리(free)로 인식하여 임의의 간격(100ms)으로 소정시간 동안(200ms) 링 요구신호를 출력하며(step 13), 만약 소정시간 동안(200ms) 소정 간격(100ms)으로 신호가 입력되면 가입자 비지(busy)로 인식하여 연결을 종료한다(step 14).Secondly, the incoming operation maintains the standby state as shown in FIG. 2 (step 10) after outputting the occupied signal for a predetermined time (200 ms) (step 11), and if there is a response for a predetermined time (195 ms) or more. (step 12), it recognizes the subscriber free and outputs the ring request signal for a predetermined time (200ms) at a predetermined interval (100ms) (step 13), and if a predetermined time (200ms) at a predetermined interval (100ms) If a signal is input, the connection is recognized as a subscriber busy (busy) to terminate the connection (step 14).

이후, 응답으로 소정시간 동안 신호 입력이 유지된 후(step 15), 임의의 간격(100ms)으로 소정시간 동안(200ms) 신호 입력이 유지되면(step 16), 가입자 프리제어에 따른 클리어 백으로 인식하여 연결 해제를 위해 소정시간(550 ~ 850ms) 이상까지 해제 검출신호를 출력한 후(step 17), 소정시간 동안(650ms) 신호입력이 있으면 중계동작을 해제한다(step 18).Then, after the signal input is maintained for a predetermined time (step 15) in response (step 15), if the signal input is maintained for a predetermined time (200ms) at a predetermined interval (100ms) (step 16), it is recognized as a clear back according to subscriber pre-control After outputting the release detection signal for a predetermined time (550 ~ 850ms) or more for disconnection (step 17), if there is a signal input for a predetermined time (650ms), the relay operation is released (step 18).

이상에서 설명한 바와 같이 톨 교환기용 인-밴드 신호 출력방법은 인-밴드 신호를 사용하는 교환기에서 들어오는 호를 중계할 수 있으며, 또한 시험실에서 루프시험을 미리 할 수 있도록 함으로써, 현장에서 발생할 수 있는 문제점을 미연에 방지하는 등의 효과가 있다.As described above, the in-band signal output method for the toll exchanger can relay an incoming call from an exchange using an in-band signal, and also allow a loop test to be performed in a laboratory in advance, thereby causing problems in the field. There is an effect such as to prevent in advance.
