Abstract

For use in a telecommunications network containing a component to be tested ("UUT"), a system for, and method of, providing in-band and out-of-band signals to test and analyze the UUT. The system includes: (1) a programmable switch coupled to the UUT through the telecommunications network via an in-band and out-of-band signaling path capable of providing in-band and out-of-band signaling to the UUT and (2) a host controller coupled to the switch for communication of data therebetween, the host controller further couplable to the UUT via an out-of-band signaling path capable of providing out-of-band signaling to the UUT, the host controller capable of storing and executing a sequence of instructions to test the UUT via at least one of the in-band and out-of-band signaling paths, the switch being programmable and the sequence of instructions being adaptable to allow the switch and the host controller to adapt to a particular signaling protocol of the UUT.

Claims

1. A system for providing in-band and out-of-band signals to test a component to be tested (UUT) in a telecommunications network, comprising:

a programmable switch coupled to said UUT through said telecommunications network via an in-band and out-of-band signaling path configured to provide in-band and out-of-band signaling to said UUT; and

a host controller coupled to said switch for communication of data therebetween, said host controller further couplable to said UUT via an out-of-band signaling path configured to provide out-of-band signaling to said UUT, said host controller capable of storing and executing a sequence of instructions to test said UUT via at least one of said in-band and out-of-band signaling paths, said switch being programmable and said sequence of instructions being adaptable to allow said switch and said host controller to adapt to a particular signaling protocol of said UUT.

2. The system as recited in claim 1 wherein said sequence of instructions is hierarchically structured as a test suite comprising a test case, said test case comprising a test logic program (TLP), said TLP comprising a test independent building block (TIBB).

3. The system as recited in claim 1 wherein said host controller comprises a graphical user interface (GUI) for allowing a user to manipulate symbols presented on said GUI to define said sequence of instructions.

4. The system as recited in claim 3 wherein said GUI provides fields for said user to enter data pertaining to a test.

5. The system as recited in claim 3 wherein said GUI presents a series of test results to said user.

6. The system as recited in claim 1 wherein said switch is embodied as a plurality of modules, thereby allowing said switch to adapt to said telecommunications network and said UUT.

7. The system as recited in claim 1 wherein said host controller is capable of receiving result data from said UUT via said switch.

8. The system as recited in claim 1 wherein said particular signaling protocol is an out-of-band signaling protocol selected from the group consisting of:

D-channel Signaling of an Integrated Services Digital Network (ISDN), and

Signaling System 7 (SS7).

9. The system as recited in claim 1 wherein said particular signaling protocol is an in-band signaling protocol selected from the group consisting of:

Dual Tone Multi-Frequency (DTMF), and

Multi-Frequency R1 (MFR1).

10. The system as recited in claim 1 wherein said host controller comprises circuitry for scheduling an execution time for said sequence of instructions.

11. The system as recited in claim 1 wherein said host controller comprises a user interface for allowing a user to define a sequence of instructions and expected results, said host controller compiling a series of tests results and validating said test results, said host controller further generating a report reflecting said test results.

12. A method of providing in-band and out-of-band signals to test a component to be tested (UUT) in a telecommunications network, comprising the steps of:

coupling a programmable switch to said UUT through said telecommunications network to establish a signaling path configured to provide in-band and out-of-band signaling to said UUT; and

coupling a host controller to said switch for communication of data therebetween, said host controller further couplable to said UUT to establish an out-of-band signaling path configured to provide out-of-band signaling to said UUT, said host controller capable of storing and executing a sequence of instructions to test said UUT via at least one of said in-band and out-of-band signaling paths, said switch being programmable and said sequence of instructions being adaptable to allow said switch and said host controller to adapt to a particular signaling protocol of said UUT.

13. The method as recited in claim 12 wherein said sequence of instructions is hierarchically structured as a test suite comprising a test case, said test case comprising a test logic program (TLP), said TLP comprising a test independent building block (TIBB).

14. The method as recited in claim 12 wherein said step of coupling said host controller comprises the step of providing a graphical user interface (GUI) for allowing a user to manipulate symbols presented on said GUI to define said sequence of instructions.

15. The system as recited in claim 14 wherein said step of coupling said host controller comprises the step of providing fields for said user to enter data pertaining to a test via said GUI.

16. The system as recited in claim 14 wherein said step of coupling said host controller comprises the step of presenting a series of test results to said user via said GUI.

17. The method as recited in claim 12 wherein said switch is embodied as a plurality of modules, said method further comprising the step of allowing said switch to adapt to said telecommunications network and said UUT.

18. The method as recited in claim 12 further comprising the step of receiving result data from said UUT into said host controller via said switch.

19. The method as recited in claim 12 wherein said particular signaling protocol is an out-of-band signaling protocol selected from the group consisting of:

D-channel Signaling of an Integrated Services Digital Network (ISDN), and

Signaling System 7 (SS7).

20. The method as recited in claim 12 wherein said particular signaling protocol is an in-band signaling protocol selected from the group consisting of:

Dual Tone Multi-Frequency (DTMF), and

Multi-Frequency R1 (MFR1).

21. The method as recited in claim 12 further comprising the step of scheduling an execution time for said sequence of instructions.

22. The method as recited in claim 12 wherein said step of coupling said host controller further comprises the steps of:
