MY DIR 605l is A1 hardware version, and for some reason, the VCT function doesn't work at all.... Except for telling me the link is up/down.
This function can be accessed in Maintenance > System Check > More Info. It either says "(T/R)xPairNormal Cable" or "(T/R)xPair Error at meters".
Why doesn't it show the actual number of meters to the fault location?
(I have this requirement at present, a long cable is not achieving the link properly.)
