This announcement device can make the announcement heard from the beginning at the same time that the communication path is connected to a plurality of announcement listening requests. Also, it is assumed that this announcement device has recorded a message of 30 seconds.

Next, the operation of this embodiment will be described.

FIG. 5 is a flow chart of the announcement connection reservation process, FIG. 6 is a flow chart of the announcement connection waiting timer count process, FIG. 7 is a flow chart of the announcement connection process, FIG. 8 is a flow chart of the announcement end process, and FIG. 9 is a announcement interruption process. It is a flowchart.

When there is a connection request from the subscriber 1, the connection reservation flow process shown in FIG. 5 is performed. The announcement request call of the subscriber 1 is transmitted by the announcement connection circuit 2 in the telephone exchange 10.
0, in this case, the presence / absence of another announcement connection is determined (step 41), and the announcement connection circuit 20 hunts and secures the announcement connection request list linkage table 15 of the announcement information data shown in FIG. 4 ( Steps 47, 48). Next, the announcement memory 16 for registering the announcement is hunted (steps 49 and 50), the reservation is registered (step 51), the timer is set, the countdown is started (step 52), and the reservation processing is performed. Set (step 53).

The announcement connection list linkage table 15 is prepared for each announcement message to be connected. When this table is hunted and secured, the waiting time is set in the connection waiting timer. The reason for providing this timer is that if each call was separately connected to the announcement device, a large number of announcement devices and lines would be required, so a certain number of announcement request calls could be received at the same time. In order to connect to one line and listen to the announcement, the announcement connection is attempted at the same time by timing the announcement connection. This timing is 10
Seconds. Now, the subscriber 1 is registered in the announcement memory 16, and the countdown of the timer is started by the flow shown in FIG. That is, 1 is counted down from 1 second every 10 seconds (step 61), and when the countdown is completed (step 62), an announcement connection request is sent (step 64), and an activated timer is searched (step 63), The countdown is started (step 65). If the countdown has not ended, the process returns to step 61 and repeats the countdown.

If a connection request for the same announcement is issued from the subscriber 2 and the incoming trunk 6 within 10 seconds at the same timing when the subscriber 1 is registered and the timer countdown is started, the announcement of the telephone exchange 10 is announced. The connection circuit 20 determines by the process of the reservation flow of FIG. 5 that there is a call of the subscriber 1 who is already connected to the corresponding announcement in step 41 and the call is in the connection waiting state (step 42). The announcement memory 16 is hunted (step 43), and the connection reservation is registered in the announcement memory 16 in which the subscriber 1 is registered (step 45).

When the countdown (10 seconds) at the same timing ends, the state shown in FIG. 2 is obtained.
The announcement connection circuit 20 makes an announcement connection. In this announcement connection, a call path connection request is made according to the flow shown in FIG. 7 (step 71), and if connection is possible (step 72), the OGT 8 is hunted first to connect the path to the announcement device. When the response signal is returned, the calls registered in the announcement memory are sequentially connected to the path (step 73). When the connection is impossible (step 72), the countdown of the connection waiting timing is restarted (step 76). At the same time, it is checked whether or not the next linkage table is hunted (step 74), and if it is hunted, connection for the announcement memory of the next linkage table is executed (step 75).

Next, the announcement end process will be described with reference to FIG.

Signal of end of announcement (eg disconnect signal)
When receiving the notification, the announcement connection circuit 20 sequentially releases the calls registered in the announcement memory 16 (step 8).
1), transition to the state transition to call disconnection. When all the calls are released from the announcement device 5, the announce memory is released (step 82), and when the release of all the calls is confirmed (step 83), the announce connection list linkage table 15 is released and the processing is completed. (Step 84).

When the subscriber n in the announcement connection disconnects the call (step 91), the announcement connection circuit 20 performs the announcement connection release processing by the announcement interruption processing shown in FIG. 9 (step 93). If the call is a call for which an announcement is reserved (step 92), the call is removed from the announcement memory 16 (step 94).

[0024]

As described above, according to the present invention, with respect to the announcement request call to the announcement device connected to the subscriber line, the announcement request calls generated within a predetermined short time are sequentially registered, and the predetermined time is given. When it passes, one line is connected to the corresponding announcement source, all registered announcement request calls are connected to that line, and the corresponding announcement source can be heard from the beginning. There is an effect that the number of subscriber lines provided is small, and therefore, there is also an effect that a private or commercial announcement device connected to the subscriber line can be easily provided. Furthermore, in that case, an effect of preventing incomplete calls due to a rapid increase in traffic can be expected.
