Abstract

The invention is a test system that gives the user a single point of control to generate calls and run tests on a switching system for use in a communications network. The test system is capable of generating calls through a tandem switching system without using a local access switch. The test system is operationally coupled to the switching system by a signaling link and a call connection. The test system receives a first user request to generate a call. The test system transfers signaling to the switching system over the signaling link to cause the switching system to extend the call connection. The test system receives a second user request to run a test, and applies the test to the call connection. In some embodiments, the test system includes a web server that interfaces with a web browser operated by the user. The web server transfers information for screen displays to the web browser. The web server collects user requests from the web browser to generate calls and run tests. The web server transfers signaling, such as an initial address message, to a signaling point for formatting. The signaling point forwards the signaling to the switching system to generate calls. The web server also transfers a test instruction to test equipment. The test equipment applies the test to the call connection and returns the test result to the web server. The web server displays the test result to the user through the web browser.
