Abstract

PURPOSE:To attain talking interruption by outputting channel information from an opposite station when a call signal is transmitted to an interphone set during talking. CONSTITUTION:While a calling station e and a called station F use a specific channel for talking, when an interphone set (interrupting station) G hooks off a handset and dials a station number of the called station F, a busy tone is caused and when the interruption station G applies special dial operation for calling further, the called station F transmits a call signal to an information line B. Thus, the interruption station G discriminates it to recognize a channel number used by the calling station e and the called station F, and the interruption station G is connected automatically to the channel to attain talking interruption.

As shown in the general flowchart in Figure 3, the microprocessors of F and G initialize the internal memory and I10 port (step 3o1), and then determine whether or not the handset of the local station is turned on by turning on the hook switch. (Step 30
3), and if the handset is not picked up,
The process moves to a calling signal judgment (step 3'04) to determine whether there is a calling signal shown in the figure, and if there is no calling signal shown in Fig. 2, it is again judged whether or not the handset is picked up (step 3o3). The process returns to step 304 and repeats operations between this determination and the call signal determination (step 304).

Intercom device E (hereinafter referred to as calling station E)
When the user picks up the handset, the microprocessor determines that the handset has been picked up (step 303), and proceeds to call processing (step 312). Call processing (
When step 312) is completed, the calling intercom device F outputs the calling signal shown in FIG. 2 to the information line B.
It is determined whether or not there is a response signal from the called station (hereinafter referred to as called station F) (step 313). If there is no response signal, the call termination process (step 311) is performed and the handset is determined again (step 313). Move to step 3o3).

When the calling station E performs the call processing (step 312), all intercom devices F connected to systems other than the calling station E output the calling signal shown in FIG. 2 to the information line. (The microprocessor of r reads the calling signal shown in FIG.
06), and if the own station is not called, the process moves to the handset/receiver determination (step 3o3) again. The called station F performs the same process, but since its own station is being called, it emits a ring tone (step 307) to indicate that the call has been completed, and the calling stations E and V also emit the ringing signal shown in Figure 2. It connects its own station to the communication path specified by the channel designation signal Sb, and further outputs the ringing sound to the communication path. As a result, calling station E
It can be seen that called station F is being called.

Next, the called station F monitors whether or not its own handset has been picked up (step 308), and if the handset has not been picked up, a timeout judgment is made to determine whether the ringing time has elapsed over a specific time. (Step 302) is performed, and if the timeout has not occurred, the process moves to ringing again (step 3o completed) and continues outputting the ringing tone. When you pick up the handset, the process moves to call processing (step 3o9), and you are in a call state.
After processing, a Funk's isothiooff determination is made to determine whether or not the handset of the own station has been lowered (step 310). If the handset is up, the hook switch is lowered (1), and monitoring is continued, and when the handset is lowered, Ending process (step 311)
and returns to standby operation.

When called station F is ringing, if interrupting station G makes an interrupt, even if called station F does not pick up the handset and answer, the call from calling station E will be interrupted by interrupting station G. A proxy response can be made in place of the called station F. However, if the called station F is ringing and a paging signal (Fig. 2) from the interrupting station G is sent to the microprocessor of the called station F, the ringing tone will be temporarily stopped during this time. must output the information on the call route number being used by the operator, and the ring tone will be interrupted.To prevent this, the output signal from interrupt station G (Figure 2) must be sent immediately after the dial operation. If there is no emitted response signal from the called station F, the called station F determines that the ringing tone is ringing, and after a certain period of time has elapsed, the interrupting station G automatically issues a ringing signal (the first (Fig. 2).

Since there is no reply, the second calling station G outputs a second calling signal to the information line again after a period of time T (shown as calling signal D7 in FIG. 4). Number 3 in the fourth (2) indicates the second calling signal from the second calling station G in the calling or response signal D5 that can be output to the information line. At this point, the ringing tone of the called station F is in a paused state, so the receiver reads 3 in the second ringing signal, and then determines whether or not the own station is being called. If the call is completed, the called station F sends a paging signal (D5Fi in Figure 4), including information on which communication path is being used among multiple communication paths.

When the calling station E picks up the handset, dials the station number of the called station F, and the called station F responds, the calling station E and the called station F enter into a communication state. Since the operation is the same when the second calling station G interrupts either of these two stations, the operation of interrupting the called station F will be explained here. When the second calling station G dials the station number of the called station F (D6 in FIG. 4 indicates the dial operation signal F of the second calling station G), the second calling station A call signal (shown as D7 in the figure) is output to the information line. 2 in FIG. 4 shows the paging signal of the second calling station G in the paging or response signal D3 outputted to the information line. The called station F reads 2 into the output paging signal and determines whether or not its own station has been called, and if it has been called, it responds with the number of communication path it is using. signal (response signal DsV output from called station F in Fig. 4)

(al) When a third intercom device makes a call from a third intercom device to an intercom device that is ringing at an interval between ringing on and off when the calling station is unable to ring, the caller picks up the call while the ringing tone is paused, and selects which call route. Since the third intercom device is configured to send back information as to whether the intercom device is using the third intercom device, it is possible to respond to a call from the calling station on behalf of the called station.

('b) If the calling station or the called station is called from the third intercom while the calling station and the called station are talking, the call will be accepted even during the call, and the call path will be displayed. Since information can be sent back, it has the advantage of being able to interrupt a call and allowing a third party to make a conference call.

Each terminal is equipped with a microprocessor capable of standby processing, response processing, call processing, ringing, call processing, and call termination processing, and selects a specific call route from among multiple call routes. When a calling signal is sent to an intercom device that is currently making a call, the other station outputs call path information, automatically connects the own station to that call path based on this information, and interrupts the call. Call interruption method.
