ADSL combi tester at a competetive price: the ARGUS®42 PLUS tests ADSL, and optionally ISDN and POTS. In addition to the various service types and protocols, the tester also determines e.g. the attainable transmission speed or noise floor of the line.

The ARGUS42Plus can set up voice calls to test and evaluate not only POTS and ISDN connections, but also calls placed via VoIP. The ARGUS®42 PLUS evaluates the voice quality, delivers a MOS value (using E model) and determines the Media Delivery Index (MDI) of IPTV streams.
