The DCT20 analyser of digital connection 2 Mbits is an handheld multi-function equipment for the TEB test (binary error rate) for in or out-of-service lines and for digital signal analysis.
DCT 20 can work in framed or unframed mode end-to-end and in loop back mode for the test of digital channels.
The analysis functions of timeslot, direct access, configuration and of result storage are integrated.
With the optional data module, the DCT20 can provide the checking of V.24, V.35 and V.11 interfaces between the DTE (Data Terminal Equipment) and the DCE (Data Communication Equipment), both in synchronous and asynchronous modes.
Results can be stored in-house and logged on PC via USB port.
