Abstract

PURPOSE:To transmit a faulty state in audible tone without the provision of an exclusive analog sound generator by connecting semi-fixedly a subscriber to a digital sound generator via a digital switch depending on a faulty condition. CONSTITUTION:A subscriber trunk SUBT is connected to the audible tone of a digital tone generator TNS via a digital network SW in response to a present faulty condition of a station. In this state, the maintenance personnel of a master station dials a subscriber number assigned to this subscriber terminal to recognize the state of this unattended station. This request call enters from the master station via an incoming trunk ICT. In this case, however, since the line is in busy state, the interruption connection is conducted. That is, the ICT is interrupted and connected to the subscriber SUBT via a mixing trunk MIXT. When the interruption connection is conducted, the audible tone displaying the fault state transmitted to this SUBT is transmitted also to the master station via the ICT. The faulty state of the unattended station is recognized by the audible tone in this way.

Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to a digital communication system installed in an unmanned station.

Fault information can be sent from the switching device at the request of the master station.

This relates to a method of transmitting audio by listening. .

[Background of the invention]

According to the type of failure, the subscriber terminal of the unmanned station.

A fault control device that can send out different audible tones is connected, and a call is received from the master station to the subscriber terminal.

A commonly used method is to find out the failure status.

In conventional exchanges, where various audible sounds were obtained from analog sound generators, the sound source for this fault control device could be easily obtained from it, but now that the audible sound source has been digitized and distributed via digital switches. The digital exchange system used has the disadvantage that a dedicated analog sound generator is required.・[Objective of the Invention] The object of the present invention is to provide a digital switching system; ・without having to install an analog sound generator exclusively for the fault control device, and without even using the fault control device itself;
At the request of the master station, the call is received on a specific subscriber terminal,
This provides a means for transmitting different audible sounds depending on the content of the disorder.

[Summary of the invention]

Therefore, in the present invention, a specific subscriber terminal is used.

Digital sound generator according to the station's fault situation.

There are digital switches for different audible parts.

Therefore, a means for connecting semi-permanently (switching the connection when the failure situation changes) is provided, so that the particular subscriber appears to be having a pseudo-conversation with the sound source.

The terminal enters a busy state and requests the failure status from the master station.

Therefore, when a connection request is made to the subscriber terminal, an interrupt connection is made and an audible sound to which the subscriber terminal/child is connected is sent back to the master station. Embodiment] An embodiment of the present invention will be described with reference to the drawings. In Figure 11, 5 UBTs are provided for each subscriber terminal.

The subscriber trunk and SW are digital audio.

Tsuchi network, TNS is digital sound generator, ICT is input trunk, MIXT is MI.

This is the afternoon sing trunk. Figure (a) is for transmitting an audible sound indicating the problem in response to a request from the master station.

A subscriber trunk (S.

UBT) 7, via a digital switch network (SW) depending on the current fault status of that station.

This shows the state where the digital sound generator 'I'NS is connected to the corresponding audible sound. This is performed by a processor (not shown) depending on the occurrence of the failure. Therefore, it is normally normal.

For example, if a major failure (MJ failure) occurs, the subscriber terminal (5UBT) is connected to an audible tone that indicates that there is no failure. Continue in that state until the situation improves. In this way, it is provided to send out the details of the problem in an audible tone.

The subscriber terminal (SUBT') connected to the digital sound generator is always connected to the digital sound generator, including in a normal state without a fault, and is virtually always in the same state as when a call is in progress. In such a situation, the maintenance/caller of the master station dials the subscriber number assigned to the subscriber/terminal in order to know the status of this unmanned station.

In Figure (b), the requested call is sent from the base station to a normal person.

It comes in via trunk (ICT) Y. death.

However, in this case, the subscriber was in a busy state.

An interrupt connection is then made. of this interrupt connection.

In the digital exchange system, the well-known Miki 5 Simbutrank (MIXT) is used, and the exchange is carried out by the same well-known means. Figure (b) shows the incoming trunk (IC
T) is connected to the subscriber (8UB'I'') via the Miki Shinbutsu trunk (MIXT). When the interrupt connection is made, the failure status that is sent to the subscriber is displayed. The audible sound is incoming trunk (ICT)'
& After that, it is also sent to the parent/station maintainer. In this way, the maintenance personnel of the master station can confirm the failure status of the unmanned station with audible sound.
You can know.

〔Effect of the invention〕

As described above, according to the present invention, the fault control device itself, which was conventionally connected to the addition/input terminal.

Lose your subscriber to a digital sound generator.

Depending on the fault situation, you can make a semi-permanent connection via a digital switch, and there is no hardware problem.

Failure condition according to the request of the parent station without any increase in the number of alarms.

You can send the status information back to the parent station with an audible sound.

I'm going to growl.

Claims (1)

[Claims] 1. In a digital exchange where the audible sound source is digitized and distributed via a digital switch, a specific subscriber's terminal is semi-fixedly switched to a different audible sound depending on the nature of the fault at the station via the digital switch. A failure type/specific transfer method characterized in that a means for connecting is provided, and in connection with the content of the failure from another station, an interrupt connection is made to the subscriber/subscriber terminal to transmit an audible sound according to the failure type. .
