Argus 155 – xDSL, PSTN
and VoIP in one handset

compact xDSL-Tester for daily use

The NGN combi tester (ADSL tester, VDSL tester, SHDSL tester), the ARGUS 155 contains an extremely powerful ADSL/VDSL chipset that meets today’s demanding technical requirements. The ARGUS 155 is the only handheld tester and analyzer to integrate VDSL2 (all profiles), ADSL (Annex A, B, J, L, M) and SHDSL (2, 4 and 8 wire), Ethernet, ISDN PRI/E1, BRI/S/T/U and POTS interfaces in a single measurement device – without having to swap modules.

Thanks to its Gigabit Ethernet interface (GigE), the ARGUS 155 achieves a download speed of up to 200 Mbit/s with HTTP and FTP downloads, such as is already standard with fiber optic modems (ONT) on the LAN interface. If the Ethernet cabling is faulty, the ARGUS 155 can immediately locate the source of the fault by means of cabling tests via the GigE interface. This makes it possible, for instance, to detect shorts, opens or mismatches, but also the delay or polarity of the wire pairs, among other things.
Flexible expansion capabilities mean that the existing interfaces can be extended with additional functions, as required. For example, the SHDSL interface also operates in SHDSL.bis as well as optionally in ATM, TDM or EFM modes. Copper tests (Cu tests) for physical line qualification without synchronization with the DSLAM are always included. If necessary, these tests can also be considerably extended in the field by simply connecting the new compact ARGUS Copper Box via USB, thus enabling all important electrical parameters such as voltage, current, isolation resistance, symmetry and many more, to be automatically and quickly determined via tip, ring and ground. The TDR (Time Domain Reflectometer) function makes it possible to measure line lengths and trace sources of faults. A high-impedance connection enables a Line Scope to display the time and frequency domains (FFT) in real time. The optional Active Probe II, which is required for this, can be connected to an existing DSL connection and switched between symmetrical and asymmetrical operation.
