Abstract

PURPOSE:To surely and quickly inform the presence of a message from a person served by the message service system by blinking a lamp of a telephone set with message lamp of an extension to be set at the setting of the message service and ringing the call tone intermittently. CONSTITUTION:When a message service is set to an extension telephone set 1 with message, a central controller 4 sends an instruction signal blinking a message lamp to a control section of a subscriber circuit 2 at first, then the central controller 4 receives a time signal sent for each set time by a timer 5 in advance. The central controller 4 controls the master switch 3 for each reception to repeat connection/disconnection of a telephone set call signal source 6 and the subscriber circuit 2 to send an intermittent call signal to the extension telephone set 1. Thus, the message lamp of the set extension telephone set 1 is blinked and the call tone is rung intermittently by a call signal to recognize the presence of the message.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to message services in electronic private branch exchanges.

(Prior Art) In a conventional message service system, a subscriber is notified of the presence of a message by lighting up a message lamp of a telephone equipped with a message lamp.

(Problems to be Solved by the Invention) The conventional message service system described above has the disadvantage that it is difficult to attract attention because the existence of a message is notified simply by lighting up the message lamp of a telephone equipped with a message lamp.

In particular, if the telephone is placed in a conspicuous place, there is a drawback that unless the person to be set up pays particular attention, he or she may not notice the lamp being turned on.

An object of the present invention is to eliminate the above-mentioned drawbacks by controlling the blinking of the message lamp of a telephone equipped with a message lamp, intermittently transmitting a telephone ringing signal to the extension line, and emitting an intermittent ringing tone. The objective is to provide six message service methods that are configured so that users can easily notice them.

(Means for Solving the Problems) A message service system according to the present invention includes a control means,
Message notification means.

The control means is intended to control the blinking of the message lamp of the telephone equipped with a message lamp.

The message notification means is a round type that intermittently sends a telephone ringing signal to the extension and notifies the presence of a message by flashing the message lamp of the telephone equipped with a message lamp and by intermittent ringing of the ringing signal. be.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram schematically showing one embodiment of the main components of an electronic private branch automatic switching system that implements a message service system according to the present invention.

In FIG. 1, 1 is an extension telephone with a message lamp, 2 is a subscriber circuit of the extension telephone 1 with a message lamp, 3 is a main switch, 4 is a central controller, 5 is a timer, and 6
is the telephone ring signal source.

The subscriber circuit 2 has a ninth control section for blinking a message lamp, and a timer S sends a time signal to the central control unit 4 at preset intervals of nine fixed times.

The main switch 3 is connected via a subscriber circuit 2 to an extension telephone 1 with a message lamp and a telephone call signal source 6 of a central control unit 4. Sara K, central control unit 4
A subscriber circuit 2 and a timer 5 are connected to.

When the message service is set up for the message extension telephone 1, the central control unit 4 first sends the subscriber circuit 2
A command signal to blink the message lamp is sent to the 0 control unit.

Subsequently, the central control device 4 receives time signals sent by the timer 5 at preset intervals.

Each time a signal is received, the central controller 114 controls the main switch 3 to repeatedly connect/disconnect the telephone ringing signal source 6 and the subscriber circuit 2. As a result, an intermittent ringing signal is sent to the extension telephone 1.

As described above, the message lamp of the extension telephone 1 to be set flashes, and the ring tone sounds intermittently in response to the ring signal, thereby making it possible to know the presence of a message.

(Effects of the Invention) As explained above, the present invention, when setting up a message service, flashes the lamp of the telephone equipped with the message lamp of the extension to be set up, and also makes the ringtone intermittently sound. This has the effect of being able to reliably and quickly notify the existence of a message.
