Abstract

1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION

사령전화 시스템.Command phone system.

2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention

디지털 전송시스템에 사령전화장치를 접속하여 사령전화 기능을 향상시킨다.Improve the command phone function by connecting the command phone device to the digital transmission system.

3. 발명의 해결 방법의 요지3. Summary of the Solution of the Invention

병렬 구성되어 각 스테이션에 위치되는 다수의 다중화장치들과, 다중화장치에 연결되는 사령전화기들과, 조작 반과 다중화장치들 간의 통화로 형성을 제어하는 주장치를 구비하는 사령전화시스템에서 발신통화, 착신통화 및 회의통화 기능을 서비스한다. 발신통화는 조작반 훅크오프시 신호채널을 점유하여 해당하는 사령전화기 연결된 다중화장치로 호출신호를 송출하며, 사령전화기 응답시 응성채널을 점유하여 발신 통화 서비스를 수행한다. 착신통화는 사령전화기 훅크오프시 신호 채널의 훅크오프 상태를 확인하여 조작 반에 호출신호를 송출하고, 조작반 훅크오프시 음성채널을 점유하여 착신 통화 서비스를 수행한다. 회의 통화는 신호채널을 점유하여 순차적으로 해당하는 사령전화기들이 연결된 다중화장치에 호출신호를 송출하고 응답시 사령전화기들의 음성 채널들을 디지털 믹싱하여 조작반의 디지털 연결한다.Outgoing calls and incoming calls in a command telephone system having a plurality of multiplexing devices arranged in parallel and located at each station, command telephones connected to the multiplexing devices, and a claim for controlling the formation of a call between the operation panel and the multiplexing devices. And conference call function. The outgoing call occupies a signal channel when the operator panel hooks off and sends out a call signal to a multiplexing device connected to a corresponding command phone, and performs an outgoing call service by occupying an answering channel when the command phone responds. The incoming call checks the hook-off state of the signal channel when the command phone is hooked off, sends a call signal to the control panel, and performs the incoming call service by occupying the voice channel when the control panel hooks off. The conference call occupies a signal channel and sequentially transmits a call signal to a multiplexing device to which corresponding command phones are connected, and in response, digitally mixes voice channels of the command phones to digitally connect the control panel.

4. 발명의 중요한 용도4. Important uses of the invention

사령전화시스템을 디지털 전송 방식으로 디지털, 사령전화 기능의 신뢰성을 향상시킬 수 있다.Digital transmission of the command telephone system can improve the reliability of digital and command telephone functions.

Claims

A command telephone apparatus using a digital transmission system, comprising: an operation panel, a command telephone unit, an operation panel connection portion connected to the operation panel, a line connection portion connected to a digital line, and a digital conference portion performing a digital conference function. A main unit for performing outgoing initialization and incoming call function of the main unit, a line connection unit connected to another multiplexing unit in a main unit or parallel configuration, and a telephone connection unit connected to the command telephone, and a call path between the main unit and the command telephone unit And a multiplexing device, wherein the main device occupies a signal channel when a call state occurs and processes corresponding signal information, and occupies and processes a voice channel in a call mode.

In the service method of the command telephone system comprising a plurality of multiplexing devices arranged in parallel and located at each station, command telephones connected to the multiplexing device, and a claim for controlling the formation of a call between the operation panel and the multiplexing devices. In the case of hooking off the operation panel, the call signal is transmitted to a multiplexing device connected to a corresponding command telephone by occupying a signal channel, and when the command telephone is answered, the call signal is performed by occupying a voice channel; Checking the hook-off state of the channel to send a call signal to the operation panel, and during the hook-off of the operation panel to perform a call service to the operation panel by occupying a voice channel, and when receiving a group call command to seize the signal channel When the corresponding command phones send out a call signal to the multiplexing device connected and respond Service methods commander phone systems voice channel of the phone features a command constituted by any process of connecting the voice channel of the control panel with digital mixing.
