The ARGUS® 3u plus ISDN Tester verifies BRI S/T plus BRI U and POTS interfaces in TE and leased line modes.

The ARGUS® 3u plus is an impressive and versatile connection tester for ISDN and POTS interfaces. It enables an accurate installation of POTS accesses as well as BRI S/T and U interfaces, and is therefore suitable for checking all functions before and after the NTBA.

This handy tester supports automatic testing of accesses, services and supplementary services and also offers voltage and signal level measurements as well as a bit error rate test (BERT). Another function is the HF detection, which can distinguish between active BRI U and ADSL signals.

In addition, the test set features RC measurements and loop length calculation as well as an integrated mini splitter, filtering interference from ADSL frequencies. Optionally, a cabling test of the BRI S/T bus can be performed.
