<p>The traditional internal high-impedance probe (8), which allows non-intrusive tests or checks to be carried out on broadband networks, instead of being located in the test head (4), as is the conventional way, is located in the main distribution frame (9) itself, next to the master unit (1) or indeed integrated in the same box, which allows the cable (7) which joins the master unit (1) to the test head (4) to be considerably longer, even exceeding 100 metres, without causing desynchronisation between the DSLAM signal and the user's modem, when carrying out said tests.</p> |
