Abstract

PURPOSE:To inform the call duration to an extension subscriber by announcing the call time to the subscriber under a busy mode after the remote side answers and at every fixed period of time through a voice synthesizing device. CONSTITUTION:An extension subscriber 1 is stored by a switch 3 via a line circuit 2. The switch 3 also stores a central office trunk 4 and a voice synthesizing device 9 and is controlled by a central controller 6. The controller 6 actuates a timer 7 for call duration for each trunk and discriminates the message transmission frequency through a memory circuit 11 for trunk-based call duration message frequency when coincidence is obtained between the data of a memory circuit 10 for call duration message set time and the time of the timer 7. Then the controller 6 multiplies the discriminated message transmission frequency by the set time and gives the result of this multiplication to the device 9. The device 9 informs the call duration to the subscriber 1 via a route 3b based on the received call duration information.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a talk time message system for an automatic private branch exchange.

[Conventional technology]

In a conventional call time message system of this type, an extension subscriber 1 is connected to a switch 3 via a line circuit 2, as shown in FIG. The switch 3 further accommodates and connects a central office line trunk 4 and a tone trunk 5 connected to the central office line, and is connected and controlled by a central control unit 6.

Now, when the extension subscriber 1 establishes a central office line origination connection, the line 3a of the central control unit 6 and the switch 3 is connected.

Thereafter, the extension subscriber l dials the number of the other party, and when the other party answers, it is detected by the central office trunk 4 and recognized by the central control unit 6.

The central control device 6 operates the trunk-by-trunk talk time timer 7 of the corresponding central office line trunk 4. In the central control unit 6, when the call time data in the predetermined forecast sound setting time storage circuit 8 matches the call time timer 7 for each trunk, the line 3a of the switch 3 is disconnected and the line 3b is connected.

Then, a tone is transmitted from the tone trunk 5 to the extension subscriber 1. In the central control device 6, after a certain period of time, the line 3
After disconnecting the line 3a and connecting the line 3a, the central control unit 6 resets the trunk-by-trunk talk time timer 7 and operates the timer of the corresponding central office line trunk 4 again. Thereafter, the tone is sent again from the tone trunk 5 to the extension subscriber l after a certain period of time.

[Problems to be solved]

There were other problems, such as the need to know the tone of the tone and the hour of the tone timer, and the length of the call cannot be known unless one remembers how many times the tone sounds during a long call.

[Means for solving problems]

The present invention solves the above-mentioned problems, and uses an automatic private branch exchange equipped with a voice synthesizer to send calls to an extension subscriber who is currently on a call from the voice synthesizer at regular intervals after the other party answers. It announces the time and informs extension subscribers of the call time.

〔Example〕

Next, the embodiment will be described with reference to FIGS. 1 to 3.

FIG. 1 is a block diagram of a circuit to which an embodiment of the call time message system according to the present invention is applied, and FIGS. 2 and 3 are a time chart and a flow chart, respectively, for explaining the above system. In Figure 1, the same parts as in Figure 4 are given the same reference numerals.

In FIG. 2, extension subscribers are accommodated and served by a switch 3 via a line circuit 2. The switch 3 further accommodates and connects a central office line trunk 4 and a voice synthesizer [9 that connect to the central office line, and is connected and controlled by a central control unit 6.

Extension subscriber l now υ central office line origination connection (step a in Figure 3)
), the line 3a of the central control device 6 and the switch 3 is connected.

Thereafter, the extension subscriber 1 dials the number of the other party, and when the other party answers (step b in FIG. 3), it is detected by the central office trunk 4 and recognized by the central control unit 6.

The central control device 6 operates the trunk-by-trunk talk time timer 7 of the corresponding central office line trunk 4 (step C in Fig. 3).
. The central control unit 6 periodically checks whether the call time data in the predetermined call time message setting time storage circuit 10 matches the call time timer 7 for each trunk (step d in FIG. 3). If they match, the trunk-by-trunk talk time message count storage circuit 11 identifies the number of the next talk time message, and then multiplies it by the talk time message setting time. The call time up to the present is calculated, and the result is sent to the speech synthesizer 9 (step f in Fig. 3).
) Reset the per-trunk call timer 7. Next, after storing the plus 1 data in the corresponding trunk storage circuit of the trunk-by-trunk talk time message count storage circuit 11 (step g in FIG. 3), the line 3b of the switch 3 is connected (step h in FIG. 3). .

The speech synthesizer 9 sends out a speech synthesis output based on the call time information received from the central control device 6. After this transmission, the speech synthesis device 9 transmits transmission completion information to the central control unit 6 (step i in FIG. 3). After receiving the information, the central control device 6 disconnects the line 3b of the switch 3 (the third
Steve in the figure). As described above, the extension subscriber 1 can listen to the call time message from the voice synthesizer during the call.

As mentioned above, the central control device 6 periodically checks whether the call time data in the call time message setting time storage circuit IO matches the call time timer 7 for each trunk.
Verification is performed until extension subscriber l's call ends. When the extension subscriber ends the call, the central control device 6 clears the corresponding trunk data in the per-trunk talk time timer 7 and the per-trunk talk time message count storage circuit 11.

The above is a method for letting the call time message be heard also on the central office line side. However, if you do not want the central office line side to hear the call time message, before connecting the voice synthesizer 9 and the line circuit 2 via line 3b, switch After outputting the voice synthesis, the line 3b of the switch 3 is disconnected, and then the line 3a of the switch 3 is connected.

FIG. 2 shows an example in which the call time message setting time is temporarily set to 3 minutes.

〔effect〕

As explained above, the present invention allows the voice synthesizer to announce the call time up to that point to the extension subscriber during a call at regular intervals after the caller answers, and informs the extension subscriber of the call time. This has the advantage that the caller can clearly know the duration of the call during the call, which is very convenient.
