Abstract

PURPOSE:To simplify a test repeating system and to conduct the test of a subscriber stored in a remote place except for a station where a subscriber test stand is installed by providing an analog subscriber test auxiliary circuit, an ISDN subscriber test auxiliary circuit and a subscriber test main circuit which can be mutually connected to these circuits. CONSTITUTION:Subscriber information is transmitted/received between the exchange processor 3 of an exchange station B and the analog subscriber test auxiliary circuit 8 when a subscriber to be tested is an analog subscriber 7, and the ISDN subscriber auxiliary test circuit 11 when the subscriber to be tested is an ISDN subscriber 10. Then the channel of the subscriber test main circuit 2 of an exchange A is connected. Then, subscriber information is transmitted/received between the subscriber test main circuit 2 of the connected exchange station A and the analog subscriber test auxiliary circuit 8 or the ISDN subscriber test auxiliary circuit 11, and information on the subscriber to be tested is displayed in the subscriber test stand 1 installed in the exchange A.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a subscriber line test system in an ISDN exchange.

[0002]

2. Description of the Related Art Conventionally, in a subscriber line test system of an integrated exchange that accommodates analog subscribers and ISDN subscribers,
As shown in FIG. 2, an analog subscriber test main circuit 13 and I capable of transmitting / receiving subscriber information to / from the exchange processing device 3 of the accommodation station.
It has an SDN subscriber test main circuit 14 and a selection control device 12 that controls which of the analog subscriber test main circuit 13 and the ISDN subscriber test main circuit 14 is used according to the received subscriber information.

[0003]

In the subscriber line test system of the integrated exchange for accommodating the analog subscriber and the ISDN subscriber, the conventional test relay system is complicated and the exchange processing device 3 of the accommodating station is used. Analog subscriber test main circuit 13
Since the subscriber information is transmitted and received between the ISDN subscriber test main circuit 14 and the ISDN subscriber test main circuit 14, a subscriber accommodated in a remote station other than the station in which the subscriber test stand 1 is installed is tested. In this case, the subscriber information cannot be transmitted / received between the exchange processing device of the remote station and the analog subscriber test main circuit 13 or the ISDN subscriber test main circuit 14, and the test of the subscriber accommodated in the remote station is performed. There was a problem that could not be done.

[0004]

SUMMARY OF THE INVENTION A subscriber line test system of the present invention is provided in a remote place and has an analog subscriber and ISDN.
Analog subscriber test subcircuit and IS capable of transmitting / receiving subscriber information to / from a switching processor of an integrated exchange accommodating subscribers
The DN subscriber test subcircuit is connected to a test stand provided in a master station that interfaces with the integrated exchange to test a subscriber line, and is interconnected to both the analog subscriber test subcircuit and the ISDN subscriber test subcircuit. And a possible subscriber test main circuit.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing a configuration of an embodiment of the present invention, and shows an example in which a remote subscriber line test of an integrated exchange accommodating an analog subscriber 7 and an ISDN subscriber 10 is performed. ing.

In order for the maintenance personnel to test the analog subscribers 7 and ISDN subscribers 10 accommodated in the exchange B from the subscriber test stand 1 installed in the exchange A, the maintenance personnel of the subscriber under test must be tested. Designate on the subscriber test stand 1. The specified subscriber information to be tested is notified to the exchange processing device 3 of the exchange A via the subscriber test main circuit 2.

In the exchange processor 3 of the exchange A, since the subscriber under test is not the subscriber of the own station, the exchange processor 3 of the exchange B is tested via the speech path switch 4 and the interoffice speech path 5. Notify subscriber information. In the exchange processing device 3 of the exchange B,
Sending and receiving subscriber information between the analog subscriber test subcircuit 8 when the subscriber under test is the analog subscriber 7 and between the ISDN subscriber test subcircuit 11 when the subscriber under test is the ISDN subscriber 10. The subscriber test main circuit 2 of the exchange A
Connect the call path.

Next, the switching center B is connected between the subscriber test main circuit 2 of the switching center A and the analog subscriber test sub-circuit 8 or ISDN subscriber test sub-circuit 11 of the switching center B which are connected.
Subscriber information transmitted / received between the exchange processing devices 3 is displayed, the information of the subscriber under test is displayed on the subscriber test stand 1 installed in the exchange A, and the subscriber indicated by the subscriber information is displayed. Testing is possible.

[0010]

As described above, according to the present invention, the analog subscriber test subcircuit and the ISDN subscriber test capable of transmitting / receiving subscriber information to / from the switching processing device of the integrated exchange accommodating the analog subscriber and the ISDN subscriber. An analog subscriber test sub-circuit and an IS connected to a sub-circuit and a test stand provided in a master station that interfaces with the integrated exchange to test a subscriber line.
By providing a subscriber test main circuit that can be connected to both of the DN subscriber test subcircuits, the test relay system is simplified and accommodated in a remote station other than the station where the subscriber test stand is installed. There is an effect that it is possible to test the subscribers who are currently in use.
