Overview – E1/T1 BER Tester and Data Transmission Analyzer

This E1/T1 BER tester and data transmission analyzer performs error code testing at the rate of 50 b/s to 2048 kb/s and offers 2M online monitoring for routine maintenance, repair and operations monitoring of communication equipment. It offers a special remote monitoring function to perform real time monitoring through software. This tester is designed for frame synchronization code monitoring, CRC4 monitoring, offline error testing, signal waveform analysis, IP PING testing, offline and online monitoring and ITU-T G.821, G.826, M.2100 error analysis.
