Abstract
Abstract There is disclosed a method,system and board for testing an electronic equipment, particularly a telecommunication equipment. Conventionally the electronic equipments are tested as to their functionality, once assembled, as black-boxes, through dedicated test systems. Nearly always, and above all in the field of telecommunication, equipments are composed of set of boards interconnected through a bus and communicating in time division, according to a predetermined protocol. The method according to the present invention proposes to test, as to functionality, with a single apparatus all the individual boards composing the equipment, naturally by using different test sequences.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
114 words
Method of testing an electronic equipment, particularly a telecommunication equipment of the type including boards connected each other through a bus and communicating in time division according to a predetermined protocol, characterized in that said boards are tested separately in relation to their functionality and that the testing of a board comprises the steps of a) memorizing a test sequence, b) sending first signals, corresponding to said test sequence, to said board according to said predetermined protocol, c) receiving (through said bus), according to said predetermined protocol, second signals emitted by said board in relation to the sending of said test sequence and corresponding to the response sequence, and d) memorizing said response sequence.
Claim 2
Dependent Claim
27 words
Method according to claim 1, characterized in that said boards are tested separately through connection of a test system with one of said boards at a time.
Claim 3
Dependent Claim
39 words
Method according to claim 1, characterized in that said boards are tested separately through connection of a test system to said bus and by putting first a step of addressing the board to be tested before said sending stop.
Claim 4
Dependent Claim
27 words
Method according to claim 1, characterized in that said testing of a board further comprises the stop of putting out said response sequence in a suitable format.
Claim 5
Dependent Claim
28 words
Method according to claim 1,characterized in that the testing of a board further comprises the step of receiving by an operator said test sequence in a suitable format.
Claim 6
Dependent Claim
27 words
Method according to claim 1, characterized in that said testing of a board comprises a number of test cycles each comprising said steps a), b), c), d).
Claim 7
Dependent Claim
26 words
Method according to claim 6,characterized in that the test sequence relative to a cycle depends on the response sequence relative to at least a previous cycle.
Claim 8
Dependent Claim
103 words
System for testing an electronic equipment,in particular a telecommunication equipment,by respectively sending test sequences and receiving response sequences on and from a bus according to a predetermined protocol,and designed to implement the method of claim 1,characterized in that it comprises a computer capable of storing and processing said test and response sequences,and a test board electrically connected to said computer and adapted to receive from said computer said test sequences and retransmit them on said bus, to receive from said bus said response sequences and retransmit them to said computer,and and to receive and transmit control commands respecpectively from and to said computer.
Claim 9
Dependent Claim
