In this paper we present an array based network analyzer for Broadband Integrated Services Digital Networks. The analyzer is laid as a linear array processor. We describe the implementation of the analyzer's functions on the array processor. Apart the real-time application, the importance of this study becomes more apparent by the fact that, the resulting design can be implemented on configurable gate array and be attached to a microprocessor. Nevertheless, it is also possible to use the analyser array in combination with commercially available hardware to debug the network equipment in the development phase.
