Interfaces and functions
The ARGUS® 3u NT is an ISDN Tester for use in the installation and maintenance of BRI S/T/U and POTS accesses – including BRI S/T NT and monitor modes.
The ARGUS® 3u NT provides all functions necessary for installing and maintaining BRI S/T and U, as well as POTS accesses. It tests BRI S/T interfaces in TE, NT and leased line modes, including D channel monitoring and verifies BRI U and POTS interfaces in TE mode. When monitoring, D channel data can be recorded and then decoded on a PC with user-friendly filters and search functions.
In addition to automatic testing of accesses, services and supplementary services, this handy tester also offers voltage and signal level measurements as well as a bit error rate test (BERT). Other functions provided by the handheld tester include a HF detection, which can distinguish between active BRI U and ADSL signals, and an integrated mini splitter, which prevents interference from ADSL frequencies. RC testing and a line length calculation complete the scope of functions offered by the test set. A cabling test of the BRI S/T bus can also be performed optionally.
