Remote Conformance Test System for Home Bus System (HBS)

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