With intuitive, common sense menus and a comprehensive set of features, our TS250 Test Set virtually eliminates the need to learn complex ISDN protocols. We designed them to empower conventional line technicians to handle any ISDN aspect, from prequalifying a line as ISDN-capable through post-installation troubleshooting. The TS250 tests the two-wire U Interface and permits additional inspection of the four-wire S/T Interface inside the customer premises. All functions, including BERT and placing a voice call, are readily accessible with just a few keystrokes. If you need to get clarifying information for any menu or ISDN message, simply press Assist for plain-language help.
