* The MR-2000E E1 Tester is a full-featured handheld E1/Nx64K E1 tester with a variety of test capabilities. It simplifies E1 and Nx64K testing by using the categorized function keys and four soft keys which eliminate the need to go through the complicated up-and-down tree type structure. Its alarm generation and detection, error monitoring and bit error rate testing (BERT) on full or individual channels make the tester the only choice for your E1 test need.
