Interfaces and functions
The ARGUS 155 Triple Play + xDSL Combi Tester verifies VDSL2, ADSL, SHDSL, Ethernet, ISDN and POTS accesses and supports copper and Triple Play tests on top.
The high-end combi tester ARGUS 155 (ADSL tester, VDSL tester, SHDSL tester) contains an extremely powerful ADSL/VDSL chipset and is the only handheld tester and analyzer to integrate VDSL2 (up to 30 MHz), 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.
The ARGUS 155 tests the quality of VoIP, IPTV and data services over xDSL and Ethernet with optional Triple Play test functions. Thanks to its integrated handset, it can simulate not only terminal equipment such as a telephone, PC or STB, but can also determine all relevant quality parameters and evaluate voice quality according to the MOS method. It tests IPTV suitability by means of a stream analysis, a VoD test, a channel scan or an IPTV long-term analysis. Several of these IP tests can also be performed using the new, more powerful IPv6 protocol.
The large 320 x 240 pixel colour display and an intuitive menu structure, among other things, guarantee user-friendly operation. A high-performance Li-Ion battery pack ensures long operating times in the field.
