Product Description
FLUKE/HARRIS DRACON TS250 ISDN TEST SET 25475000 NEW The TS250 and TS220 basic rate ISDN test sets are perfect for prequalification, installation and maintenance of ISDN lines. The TS250 and TS220 test sets virtually eliminate the need to learn complex ISDN protocols. Both models test the two-wire U interface, while the TS250 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
With intuitive, common sense menus and a comprehensive set of features, our TS220 and TS250 test sets virtually eliminate 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. Both models test the two-wire U Interface, while the TS250 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. Features: Automated call-yourself BERT U and S/T Interface testing Supports line prequalification 64K and 56K data and voice calls On-line Assist key explaining complex messages in plain English Amplified speaker Backlit Liquid Crystal Display (LCD) and backlit keypad Impact-resistant and water-resistant Operates on 4 AA alkaline or rechargeable NiCad batteries
