ISDN-PAS: an ISDN performance analysis system

The integrated services digital network performance analysis system (ISDN-PAS) is a software tool developed for analyzing the performance of voice calls on ISDN. It takes raw call control data collected from the D-channel of the basic rate interface (BRI) of digital subscriber loops (DSL), reconstructs the original call control sequences, and generates performance statistics for the switches and networks. ISDN-PAS is written in C and runs in either a Unix or an MS-DOS environment. Owing to its general-purpose design, it can be used to analyze the performance of basically any ISDN configuration-whether emulated or a real end-user environment.<>
