Description

Description: TECHNICAL FIELD The present invention relates to a first telephone set and a second telephone set which are connected to each other when there is an interrupt request to the first telephone set from another telephone set.
The present invention relates to a telephone device for transmitting an interrupt notification sound to a first telephone. [Prior Art] In the conventional interrupt notification method, when there is an interrupt request signal from an interrupt requesting subscriber, a fixed interrupt notification sound is given to the interrupted subscriber during a call at fixed intervals. For example, a method such as transmission to the user was used. Such a system has a drawback that the interrupt function is not fully utilized because the interrupt notification sound is missed or misunderstood as a kind of noise. [Purpose] An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art, and to provide a telephone device capable of notifying a person to be interrupted of a highly urgent interrupt request. FIGS. 1 and 2 show an embodiment of the present invention, wherein reference numerals 1 to 4 denote line cards of subscriber telephone interfaces Tel1 to Tel4, reference numerals 5 to 8 denote interfaces of subscriber telephones, and reference numeral 9 denotes line switching. Reference numerals 10 to 13 denote respective interrupt sound generating devices TONE1 to TONE4, 14 denotes a central control device for controlling the exchange unit 9, 15 denotes a RAM, and 16 denotes a ROM which stores control programs and control data. FIG. 2 is a control flow of the present embodiment. In FIG. 1, it is assumed that Tel1 and Tel2 are line-connected. In this state, when an interrupt request operation is made from Tel3 to Tel1, an interrupt request signal is transmitted to 14 central control units through the 7 line cards. When detecting the interrupt request signal, the central controller 14 increments a counter using a certain area of the RAM 15 by one. This counter is reset to 0 at the start of a call. When the interrupt request signal is the first time, TONE1 is transmitted at the second time, TONE2 is transmitted at the third time, TONE3 is transmitted at the third time, and TONE4 is transmitted to the Tel1 as the selected interrupt notification sound after the fourth time. Here, each of the interrupt notification sounds TONE1 to TONE4 is a different sound.
It is assumed that ONE1 <TONE2 <TONE3 <TONE4. By doing so, in Tel1, in Tel3, the interrupt notification sound gradually increases and can be heard every time an interrupt request operation is performed. In the above embodiment, the number of interrupt sound generators may be one, and in that case, a signal corresponding to the number of interrupt request signals is output from the central controller 14 to the interrupt sound generator, and the interrupt sound generator is What is necessary is just to change the volume according to the signal from the control device. The change in the volume of the interrupt sound may be performed in the line card 5, the telephone 1, or the like. Further, in the above embodiment, the interrupt sound generating device may be a voice synthesizing device or the like, and in that case, guidance on how to receive an interrupted call can be transmitted to the interrupted subscriber instead of the interrupt sound. In this case, the central control device may select the content to be output from the speech synthesizer according to the number of interrupt request signals. [Effect] As described above, according to the present invention, it is possible to strongly notify the interruptee that an interrupt request has been made many times during a call and to respond to the interrupt request with high urgency. Can be.
