BACKGROUND OF THE INVENTION
The present invention relates to a voice output confirmation test method in a time signal guidance service system for an exchange to provide a time signal guidance service.
[0002]
[Prior art]
Currently, as a service to users on the telephone network, for example, the weather forecast service allows you to receive weather forecast services in other areas by connecting to the outside of the city, but the time information service is Since it is standardized nationwide at a standard time with no time difference in Japan, it is provided by an exchange that accommodates users.
[0003]
FIG. 8 shows an example of a system that provides a time information service in the user accommodation area. In the exchange building 50, a time voice signal is connected to a predetermined accommodation position of the exchange 53 via a toy amplifier 51 and a toy trunk 52. By dialing a predetermined telephone number, for example, “117” on the NTT line, from the user terminal 54 or in-building terminal 55 connected to the user line accommodated in the exchange 53, a time signal guidance service is provided to the dialed terminal. I am doing so.
[0004]
In such a time signal guidance service system, in order to improve the service, it is necessary to check whether or not the exchange correctly provides a time signal guidance service.
[0005]
Therefore, conventionally, the maintenance person dials “117” from the user terminal 54 or the building terminal 55 accommodated in the exchange 53 to be tested, or performs a confirmation test as shown in FIG.
