Product overview
While opening 2M circuit，there is a need to judge if the errors and alert index are complied with opening conditions; while dealing with the fault location，there is a need to judge if there is any problem existing in line equipment.
BER-1560 Data Transmission Analyzer developed by DADI Telecom is small and easy to carry，and it can be used for BER testing from 50b/s to 2048kb/s as well as monitoring 2M circuit，which is the necessary tool for daily network equipment installation, troubleshooting and maintenance. It supports G.703, V.24/RS232, V.35, V.36/RS449, X.21, EIA－530/530A interfaces. It also supports RJ45 network interface, complete TCP/IP, and updating online. Its characteristic remote monitoring function makes it ideal for users to easily perform real-time monitoring to the test unit through certain software under Windows Chinese environment.
