G.INP
Just as an experiment to see if it's useful, I've changed the Large Window version of the All User Stats displays to show, by highlighting the two values (downstream only currently), anyone who has an FEC count > 0 and with Interleaving set to 1 that might indicate G.INP is running on the line. There is one user at the moment with FEC counts in the 1000-2000 and no Interleaving. Two others pop up occasionally [attached]. Two are on Huawei and the other ECI FWIW.
Show Active Users Only
Also, if you prefer you can now select an option to display only users who are currently active - this gives a more compact display (Large Window version only)
