The key features：

  The opening and maintenance of 2M circuit
  2M double circuit testing
  Various errors insertion and detection, such as bit ,Code, FAS, CRC
  2M ping testing（PPP/HDLC/Frame Relay）
  2M clock jitter testing
  Large capacity Li-ion battery guarantees more than 8 hours operation without external power source
  Large capacity data storage 
  Use PC to perform the remote control of the test set through Ethernet

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-1580 Data Transmission Analyzer developed by DADI Telecom is used by operator in 2M equipment maintenance, troubleshooting and other high-end applications and frame relay service test for the key customers. It can be used for BER testing from  50b/s to 2048kb/s as well as monitoring 2M circuit online, 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, RS485/RS422 interfaces. BER-1580 also supports 2M jitter send/receive testing, 2M Synchronous Clock testing and frame relay testing. 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.
