Abstract
본 발명은 전용선 전화기에 있어서, 송신자에게 수신자의 전화기가 링잉(RINGING)되고 있는 상태임을 알려주기 위한 전용선 전화기의 링백톤 장치에 관한 것이다.The present invention relates to a ring back tone device of a leased line telephone for informing a sender that a receiver's telephone is in a ringing state.
전용선 통신장치 즉, 전용선 전화기라 함은 송신자와 수신자가 단일 통신선로에 의해 연결이 되어 있어 특별한 호출 조작이 없이 단지 송화기를 듦에 의하여 자동으로 수신장치에 호출 신호가 인가되는 통신장치를 말하는데, 종래의 전용선 전화기는 통화희망자가 전화기를 들고 수신자가 벨소리에 응답하여 수화기를 들때까지 수신자에게 알리는 링만 울릴뿐, 전화기를 들고 있는 통화 희망자에게는 아무런 신호도 들리지 않거나 통신선로상을 흐르는 전기적 잡음에 의한 잡음성 신호만이 흐르게 되므로 통화 희망자가 전화기를 들고 대기하는 동안 불쾌감을 일으키거나 지루함 또는 답답함을 느끼게 하는 문제점이 있었다.A dedicated line communication device, that is, a dedicated line telephone, refers to a communication device in which a sender and a receiver are connected by a single communication line so that a call signal is automatically applied to a receiving device by only lifting a talker without a special call operation. Private line telephones only ring a ring to notify the recipient until the caller picks up the phone and the receiver picks up the handset in response to the ringer. Since only the signal flows, there is a problem that the caller feels uncomfortable, bored or frustrated while waiting for the phone.
이에 본 발명은 상기와 같은 점을 감안하여 사용자가 통화를 원하여 전용선 전화기를 들었을때 수신자에게 통화요구 신호를 함과 동시에 통화 희망자에게 신호가 가고 있음을 알려줄 수 있는 링백톤 장치를 설치하므로써 통화대기중일 지라도 경쾌한 링백톤을 울려주어 통화 희망자에게 불쾌감을 없애고 지루함이나 답답함을 제거할 수 있도록 한 전용선 전화기의 링백톤 장치를 제공한다.In view of the above, the present invention waits for a call by installing a ringback tone device that can notify a callee and signal a call requestor to a receiver when a user wants to call and listens to a dedicated line telephone. It provides ringback tone devices for leased line telephones that ring a light ringback tone even when they are in the middle, thereby eliminating discomfort and eliminating boredom and stuffiness.
