Abstract

A method and system for analyzing a public switched communications network from a remote place via the public Internet. The system comprises an access device which collects data from one or more links in a public switched communications network. The system further includes a server computer which receives the collected data from the access device via a dedicated network or the Internet. The server computer executes one or more applications to perform protocol analysis based on the received data. A client computer executing a Web browser may be used to communicate with the server computer via the Internet and access the outcome of the protocol analysis.
