Was the familiar good old NTE2005 faceplate filter made by Pressac? (if I got that right?)
Both the NTE2000 (with just the four IDCs -- 2,3,4,5 -- "downstream" of the low pass filter) and the NTE2005 (with the four IDCs, as the NTE2000 and the other two unfiltered IDCs -- marked A & B) were (are) made by Pressac. (And possibly other manufacturers, under license.)
Who makes the VTE2015 mentioned earlier, anyone have any idea?
As far as I can tell the VTE2015 is an unbranded "lookalike" of the ADSL Nation device, manufacturer unknown (to me).
