DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an I-interface test, and more particularly to an automatic test method for an I-interface processing device connected to an ISDN network.

[0002]

2. Description of the Related Art Recent advances in communication technology have been remarkable. At present, various services such as telephone, facsimile communication, data communication, image communication, etc. are digitized and integrated into an integrated network (ISDN) (Integrat).
ed Services Digital Network
rk) is provided. This ISDN does not have a telephone interface and a data interface as in the past, but is unified as a multi-purpose user and network interface providing various services, and is integrated as an I series of CCITT recommendation number system. It is called an I interface. This I-interface has a basic interface (for general households) and a primary group interface (for PBX adaptation) depending on the communication speed and the network control equipment capability of the exchange. And multiplexing with signal transfer and information transfer channels by the same interface. This is called an out-channel method and is one of the features of the I interface. Also, among the layers (layers) of the OSI communication function, a layer 1 necessary for setting a line between users via a network.
To 3 are defined as I interfaces. In such a test method of the I interface, a caller, a caller, and a voice confirmation test are performed at a specific telephone number with a person intervening between the calling side and the called side.

[0003]

The conventional test system has the drawbacks that a test telephone number and a line are required and that human intervention is required.

[0004] It is an object of the present invention to overcome these drawbacks.
It is an object of the present invention to provide an I-interface automatic test method for performing a test automatically without human intervention.

SUMMARY OF THE INVENTION The present invention relates to an automatic I-interface test system in an I-interface processing device connected to an ISDN network, wherein a caller and a receiver receive a telephone number and a subaddress as test calls. , The test start date and time, the calling I-interface processing device calls the ISDN network at the test start date and time, confirms the incoming call, transmits a PB tone, and calls the called I-interface processing device. Confirms the test call based on the subaddress, and upon receiving the PB sound from the calling side, returns the same PB sound to the calling side, and the I-interface processing device on the calling side returns the PB sound from the called side. The I-interface line and the I-interface processing device are tested by confirming whether or not the received PB sound is the same as the transmitted PB sound.

[0006]

FIG. 1 is a system configuration diagram for explaining an I-interface automatic test system of the present invention. The I-interface processing device 1a and the I-interface processing device 1b are connected to an ISDN network via I-interface lines 6a and 6b, respectively. The I-interface processing devices 1a and 1b are connected to the man-machine interface 8
a and 8b.

The configurations of the I interface processors 1a and 1b are the same. Man-machine interface controllers 2a and 2b for registering telephone numbers and subaddresses in advance and confirming test calls, line controllers 5a and 5b, It comprises PB transmitters 3a and 3b for transmitting PB sounds and PB receivers 4a and 4b for receiving PB sounds.

Next, the automatic I-interface test method in the above system will be described. Assume that the calling processor is an I-interface processor 1a and the called processor is an I-interface processor 1b.

The man-machine interface control unit 2 of each of the I-interface processing devices 1a and 1b on the calling side and the called side.
In a and 2b, a telephone number and a sub-address are registered in advance through the man-machine interface 8a and 8b for performing an I-interface automatic test, and a date and time are registered in order to perform an automatic test at a designated date and time.

The calling-side I-interface processing device 1a comprises:
Activated by the registration information of the man-machine interface control unit 2a, the line control unit 5 of the I interface processing device 1a
a automatically calls the ISDN network 7 via the I interface line 6a and confirms the incoming call. The man-machine interface control unit 2a sends the PB sound after the incoming call confirmation to the PB transmitter 3.
a to the called party.

The called-side I-interface processing device 1b includes:
At the time of an incoming call, a test call is determined based on the subaddress in the form shown in FIG. 2, the PB receiver 4b receives the PB sound, and the transmitter 3b
Returns the same PB sound as the received PB sound to the calling side.

The P of the calling-side I-interface processor 1a
The B receiver 4a receives the returned PB sound, and the man-machine interface controller 2a confirms that the PB sound has been returned if the PB sound at the time of calling and the received PB sound are the same.

By automatically performing a series of these processes, an automatic test of the I interface line 6a and the I interface processing device 1a can be performed.

In the above embodiment, one test telephone number is registered. However, continuous execution is possible by registering a plurality of test telephone numbers in the man-machine interfaces 2a and 2b.

[0015]

According to the automatic test method of the I-interface according to the present invention, a telephone number, a sub-address and the like are registered in advance without requiring a manual incoming / outgoing call confirmation.
By confirming the incoming / outgoing call confirmation by transmitting and receiving the PB sound through the network, there is an effect that the I interface line and the I interface processing device can be automatically tested.
