Remote conformance test system for home bus system (HBS)

We have developed a local conformance test system (CTS) for the home bus system (HBS). This paper presents a method to expand this system as a remote CTS for layers 3 and 7 of the HBS standards. We describe a constitution method of the HBS/ISDN gateway in which the two distant HBS terminals can communicate mutually through the ISDN without violating the traditional HBS standards. In addition, the definition formats of the test suites and test cases that are required for the remote conformance test are introduced by using examples of the HBS layer 7. In order to inspect the effectiveness of our proposal, we provide the system construction of the HBS and ISDN, the mutual communication procedure of the gateway, and the layer 7 testing results.
