Abstract

PURPOSE:To test an ISDN exchange, where subscriber line interface of two or more different attributes of layer 1 is stored, without providing plural test control parts, test parts, and test links by providing a connectable test trunk for every two or more different attributes of layer 1. CONSTITUTION:When subscriber's artificial call originating is tested, a central control part 8 transmits an originating test instruction and the attribute of layer 1 to a test control part 14 and controls a test link 11 to connect a line to be tested and a test trunk 10 where two or more different attributes of layer 1 are stored. The test control part 14 controls the test trunk 10 where two or more different attributes of layer 1 are stored so that the same attribute as the attribute of layer 1 received from the central control part 8 is set. By this control, an ISDN exchange 7 where subscriber lines having two or more different attributes of layer 1 are stored is tested.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a test method for ISDN exchanges, and in particular,
This invention relates to a test method for ISDN exchanges that accommodate subscriber line interfaces with two or more different layer 1 attributes.

[Prior Art] Conventionally, this type of testing method for ISDN exchanges accommodating subscriber line interfaces with two or more different layer 1 attributes includes a test control section, a test section, and a test trunk for each different layer 1 attribute. and a test link were required.

[The problem that the invention aims to solve v! 1] The above-described conventional testing method for ISDN exchanges accommodating subscriber line interfaces with two or more different layer 1 attributes requires separate deployment of multiple test control units, test units, and test links. There was a drawback.

[Means for Solving the Problems] An object of the present invention is to solve the problems of the prior art described above, and to provide an ISDN that does not require the provision of a test control section, a test section, a test trunk, and a test link for each layer 1 attribute. The purpose is to provide a test method for switching equipment.

The testing method of an ISDN exchange that accommodates subscriber line interfaces with two or more different layer 1 attributes according to the present invention includes a test section that executes several types of tests, a control section that controls the test section, and A test means for an ISDN exchange that is connected to a test section, has a test trunk that can be connected via a test link for each corresponding to a different layer 1 attribute, and accommodates subscriber line interfaces with two or more different layer 1 attributes. It is characterized by including.

[Example] Next, a test method for an ISDN exchange according to the present invention will be described with reference to the drawings.

FIG. 1 is a functional block diagram illustrating one embodiment of a testing method for an ISDN switch that accommodates subscriber line interfaces with two or more different layer 1 attributes.

In this embodiment, the ISDN exchange 7 that accommodates subscriber lines with two or more different layer 1 attributes uses a U interface (layer 1 as recommended in the CCITT I series).
interface) subscriber line 3 and S interface (C
Layer 1 interface recommended by CITT I series) Accommodates subscriber line 4. The U-interface subscriber circuit 5 and the S-interface subscriber circuit 6 are subscriber circuits for respective layer 1 attributes. Network terminal 1
is the termination device of U interface layer 1, and IS
The DN terminal 2 is a terminal device of the S interface.

For example, in the case of a pseudo call test for a subscriber, the central control unit 8 sends a call test command and layer 1 attributes to the test control unit 14, controls the test link 11, and connects the line under test with two or more Test trunks 10 containing different layer 1 attributes are connected. The test control unit 14 controls the test trunk 10 that accommodates two or more different layer 1 attributes so that the attributes are the same as the layer 1 attributes received from the central controller 8.

The above control makes it possible to test an ISDN exchange 7 that accommodates subscriber lines with two or more different layer 1 attributes. A call is made under the control of the test control unit 14 from a test trunk 10 accommodating two or more different layer 1 attributes that have the same attribute layer 1 as the line under test, and the subscriber circuit 1
After completing the 6 calls arriving at the test trunk 12 via 3,
The test control unit 14 controls the test unit 9 and transmits test patterns or test signals to subscriber lines with two or more different layer 1 attributes through the test trunk 10 which accommodates two or more different layer 1 attributes. The test patterns or test signals transmitted to the I SDN switch 7 and received via the test trunk 12 are compared, and the test results are sent to the central controller 8.
Send to.

[Effects of the Invention] As explained above, the present invention has test trunks that can be connected for each of two or more different layer 1 attributes, thereby providing subscriber line interfaces with two or more different layer 1 attributes. Testing of ISDN exchanges accommodating
This has the advantage that it can be performed without deploying multiple test control units, test units, and test links.
