Overview

This E1 BER (Bit Error Rate) tester is a compact, multi-functional, handheld E1 line test instrument, specially designed for R&D, production, installation and maintenance of SDH, PDH, PCM, and DATA protocol conversion. It features self-check and keyboard testing, extensive error and alarm generation, detection and indication. This tester provides smart menu navigation and has a large color LCD screen allowing test results to be displayed clearly. Test results can be downloaded or printed via included software. It is an ideal device for fast problem resolution, E1 PCM line access, maintenance and acceptance testing.
