JPS6166454A - Trunk line number checking system - Google Patents

Abstract

PURPOSE:To check a trunk line number easily by informing an extension sub scriber of the trunk line number by audible sound made by voice synthesis. CONSTITUTION:When an extension subscriber 1 dials to check a trunk line number, the trunk line number is read out from a memory at the object of connection of the subscriber, and sent out to a voice synthesis device 5. The extension subscriber 1 is connected to the voice synthesis device 5, and informed of the trunk line number by voice from the voice synthesis device 5. After informed of the trunk line number, the extension subscriber 1 becomes able to talk with the trunk line automatically.

Description

[Detailed description of the invention] (Technical field) The present invention relates to a station line number checking system.

(Prior art) Conventionally, a station line number check system for an automatic telephone switching machine is equipped with a set of machine display devices, and the V'3 line subscriber's operation turns on the display lamp of the station line display device corresponding to the station line. I recognized the central office line number by blinking it.

In order to make display lamps easily visible to all extension subscribers, it is necessary to install a large number of station line displays, but this has the disadvantage of increasing equipment costs. However, if multiple extension subscribers operate the system at the same time, multiple lamps will flash, making it impossible to identify them.

(Object of the Invention) The purpose of the present invention is to store a central office line number in a connection storage device in advance when connecting a circular line subscriber to a central office line, and to input the stored central office line number to an L key when an extension subscriber operates. By providing a means for notifying each extension subscriber of the office line number by voice from a voice synthesizer, the above-mentioned drawbacks can be overcome without providing the office line display device, and the office line number can be easily confirmed audibly. The purpose of this invention is to provide a central office line number checking method that enables the following.

(Structure of the Invention) According to the present invention, while the extension subscriber is talking to the office line, the office line number 'i' which is being used by the internal subscriber! l- A connection storage device that stores the 1-station line number in the automatic telephone exchange system that recognizes the central office line number, and a voice synthesizer gold plate, which is stored in the connection storage device by the operation of the extension subscriber. A central office line number check and an evening style are obtained, which are characterized in that the central office line number is shown through the voice synthesizer.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

1 to 3 are system diagrams showing one embodiment of the processing according to the present invention, and in FIG. 1, an extension subscriber 1 is connected to a central office line via a call path switch 21 and a central office trunk 3, and is engaged in a call. This is what is shown. At the time of this connection, the subscriber connection destination memory 6 shown in FIG. 4 stores the office line number of the connected office line trunk.

When the 1-circle subscriber performs a hooking operation in Figure @1, the subscriber is connected to the pulse reception trunk 4 and becomes ready to receive pulses, as shown in Figure 8g2.

The central office line side will be on hold.

In the state shown in FIG. 2, when the extension subscriber dials a friend to check the office line number, the extension subscriber reads out the office line number from the subscriber connection destination memory 6 shown in FIG. Send to. The extension IQ person is connected to a voice synthesizer 5 as shown in Figure 3, and the voice synthesizer 5 informs him of the office line number by V voice.

After the central office line number is notified, the connection automatically returns to the one shown in FIG. 1, and the extension subscriber can again talk to the central office line.

(Effects of the Invention) As described above, the present invention makes it possible to check the office line number by informing the extension subscriber of the office line number using an audible sound generated by voice synthesis when checking the number of one office line.
There is no need to install a large number of central office line display devices that provide visible notifications, and there is an effect that notifications can be made individually even if the extension subscribers operate at the same time.
