Abstract

PURPOSE:To transmit a sound reproduction output having the minimum waiting time to an incoming call by providing an announcing device which delivers plural sound reproduction outputs different in phase with time to the same message. CONSTITUTION:A reference phase signal 40 for sound reproduction output which is delivered from an announcing device 500 is read by a signal reader 70 and transmitted to a common controller 600. The controller 600 selects an announce trunk having the shorter period from the time point when a subscriber 100 delivered an announcement connection request through the message starting point from announce trunks 401 and 402 connected to sound reproduction outputs 11 and 12 respectively. Then the corresponding trunk is connected to the subscriber 100. Thus the message waiting time can be reduced for the subscriber when the message period is long.

Description

DETAILED DESCRIPTION OF THE INVENTION The present BA relates to an announcement phase control system for a telephone exchange.

Conventionally, this type of announcement connection system connects subscriber loo to announcement device 500, as shown in FIG.
When connecting to the audio output 1o of , the common control device 600 is configured to activate the announcement connection trunk 400.

As shown in FIG. 2, the announcement device 500 receives the activation signal sz and sends an activation confirmation signal ACK to the exchange via the announcement connection trunk 400 when the message start point CK of the voice output AN is reached. to be sent back. In the figure, RFC indicates the timing of messages connected to subscribers.

The subscriber is connected to 300 in FIG. 2 until the activation signal sZ is output from the exchange and the confirmation signal ACK is sent back.

Therefore, the conventional system has the drawback that the subscriber 100 is left unloaded during the waiting time a shown in FIG.

In particular, if an announcement connection call occurs immediately after the message starting point C, the subscriber 100 is forced to wait for a long period of time, at worst one message cycle T. - If the message period T is long, the subscriber is loaded for a long time;
This method has the disadvantage that there is a high probability that the subscriber will not be able to wait for the message to start and will abandon the message midway.

The present invention has been made in view of the above drawbacks, and includes providing an announcement device with a plurality of audio playback outputs having temporal phases for the same message, so that when an announcement call occurs, The present invention provides a system for shortening the waiting time of subscribers by transmitting the audio reproduction output with the least waiting time out of a plurality of audio reproduction outputs to the subscriber group.

In order to achieve the above object, the present invention has a function of transmitting a plurality of audio playback outputs with different time phases and a reference phase output signal synchronized with one of the audio playback outputs to an exchange for the same message. an announcement device, an announcement drunk is provided between each of the plurality of audio playback outputs and the exchange, and further a signal reading device is provided for inputting a reference phase output signal synchronized with the audio playback outputs to the common control device. Then, the common control device constantly monitors the phase state of the digital signal, and based on the monitoring results, the common control device grasps the phase state of each audio playback output, and when an announcement connection call occurs, The configuration is such that one audio playback output with the least waiting time is selected and connected.

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

FIG. 3 is a block diagram showing an embodiment of the announcement phase control system of the present invention. In the figure, the announcement phase control system of the present invention connects a subscriber's telephone i 100 to
A ringback trunk 300, a first announcement trunk 401, a second announcement trunk 402, a subscriber's telephone 100, and each trunk 300.
, 401 , 402
0, a common control device 600 of the exchange that controls this,
An announcement device 500 and a signal reading device 700 for reading the audio reproduction output reference phase signal 40 output from the announcement device by the common control device 600.
It is composed of:

Between these devices is the first announcement drunk 4.
01, a second audio reproduction output 12 connected to the second announcement trunk 402, and a ringtone connection path connecting the subscriber 100 and the ringback trunk 300. 20, subscriber 100 and first announcement drunk 40
Announcement connection path 3 of the first phase connecting 1
1 and a second phase announcement connection path 32 connecting the subscriber 100 and the second announcement trunk 402 .

FIG. 4 is a time chart showing the operation of the announcement phase control system of the present invention. The operation of the embodiment shown in FIG. 3 will be described below with reference to the same figure.

In FIG. 4, ANI is an announcement/mention device 50.
0 represents the timing of the first audio reproduction output 11, AN2 represents the timing of the second audio reproduction output 12 of the announcement device 500, and C in the figure represents an example of a message starting point. First audio playback output timing ANI
and the second audio reproduction output timing AN2 have a phase difference of 180' for one message as shown in the figure. P.H.
is the timing of the audio playback output reference phase 40, and the message start point C of the first audio playback output timing ANI
is synchronized with. TIMI is the first announcement 1
TIM2 is a phase signal corresponding to the second announcement 12, and TIM2 is a phase signal corresponding to the second announcement 12, both of which are created in the common control device 600 based on the audio reproduction output reference phase PH.

When connecting the subscriber 100 to the announcement device 500, the subscriber 100 is connected to the announcement closest to the message start point based on the phase signals TIM1b and TIM2. When a connection request occurs like the announcement connection request REQI in the first example in FIG. If the phase signal TIM2 is at the "l" level, the first audio reproduction output ANI is selected, and if the phase signal TIM2 is at the rlJ level, the second audio reproduction output AN2 is selected and connected to the subscriber.

In this example, when the connection request REQI is generated, the phase signal TIMI is at the "1" level, so the common control device 6
00 indicates subscriber 100 according to the message start time.
is connected to the first announcement connection trunk 401. RECl is the announcement voice that the subscriber 100 receives at this time. In the case of the second example announcement connection request REQ2 in FIG. 4, the subscriber is connected to the second announcement connection trunk 402 in a similar manner. RFe5 is the announcement voice that subscriber 1.00 receives at this time.

In FIG. 4, a indicates the subscriber waiting time, during which 100 subscribers are connected to the ringback trunk 300. In this actual example, compared to the conventional technology, subscriber 1
The waiting time a of 00 is halved on average, making it possible to improve service to subscribers. In particular, the effect is remarkable when the period T of the -message is long. Furthermore, if the subscriber's waiting time is allowed to be the same as in the past, it becomes possible to double the message cycle T (41), making it possible to respond to the diversification of services.

In the Kinomoto example, a case has been described in which two types of audio reproduction outputs with different phases are provided, but this can be extended to n types of audio reproduction outputs. In this case, n types of phase signals TlMn shown in FIG. 4 are provided and made to correspond to each audio reproduction output, and the common control device selects the one having the closest message starting point among the n types of phases.

As explained above, the present invention provides an announcement device with n types (n-2 to ω) of audio playback outputs with different message start times for the same message, and when an announcement connection call to a subscriber occurs, Among the various audio playback outputs, a method is installed to determine the one audio playback output closest to the message start point and connect it to the subscriber. This makes it possible to shorten the time and improve service. especially,
- This effect is significant when the message period T is long.

That's right, if we allow subscribers to wait the same amount of time as before.
- It is possible to increase the message period T by n times, and it is possible to respond to the diversification of services.
