ISDN (PRI) Loopback Tester

An ISDN Loopback Tester is an exceedingly user friendly cable tester. Even the architecture is pretty simple. It looks like a simple plug at first glance but the compact, rugged design makes it highly portable and usable in the tightest corners. All you have to do is simply plug the Networx® ISDN Loopback tester into the jack that you want to test or the one you are suspicious about. If the link LED on your switch is active, then that means that the connection is operating perfectly. These Loop back testers will make the life of a network administrator really easy. The Networx® ISDN Loop back tester will negate the necessity to carry a bulky network hub around.
