VIERLING Maestro: Stationary test systems for copper and fiber optical networks
Maestro Test and Diagnostic Units (MTDU) are used to test, qualify and monitor telephone and data lines. For example, Maestro can be used to qualify lines forxDSL and monitor and maintain access networks. The system consists of distributed test probes with a central analysis unit. Maestro solutions also exist for fiber optical networks (FiberCare).
Maestro is developed and marketed by the VIERLING Group’s French subsidiary VIERLING Communication SAS. For more information about Maestro, please visit the website for VIERLING Communication SAS:

VIT-A2: ADSL tester for ADSL, ADSL2, ADSL2+
The VIT-A2 DSL tester performs fast, cost-effective error analysis of ADSL, ADSL2 and ADSL2+ connections. Service technicians can use the VIT-A2 to detect faulty cabling and lines as well as incorrect supply voltages at a glance with the LED display (PASS / FAIL). They can check the complete synchronization in ADSL, ADSL2 and ADSL2+, isolate defects in splitters and modems and find incompatible modems and improperly configured DSLAM ports.
Using the VIT-A2’s FastEthernet interface, it is possible to read out connection parameters such as the line attenuation, noise margin, data rates in the upstream and downstream directions, number of synchronization attempts and bit allocation (graphical presentation format). The supplied VIT-A2 Watch software can be used to save test reports with all relevant measurement data.
ADP 100: Active Differential Probes (ADP)
The ADP100 is a 100 MHz active differential probe that allows you to connect spectrum analyzers such as the Agilent N9340 or the VIT-V2 VDSL2 tester toxDSL lines without impacting the line itself. The ADP100 is optimized for xDSL lines and provides data in both balanced and unbalanced modes.
PMP: Protected measurement points for potential-free connection
VIERLING’s protected measurement points (PMP) can be used to decouple test points on 2 Mbit/s links. In communications engineering, it is commonly necessary to make measurements on transmission links that are in operation. PMPs from VIERLING ensure that the test equipment that is connected does not negatively impact the line.
Weatherman: A weather satellite station for everyone
Weatherman combines a weather satellite receiver, a QFH antenna and software to form a complete weather satellite station. Weatherman allows you to receive automatic picture transmission (APT) signals transmitted by satellites operated by the National Oceanic and Atmospheric Administration (NOAA) in the United States. You can display the signals to obtain color or black and white weather maps.
