As an aside I see BE1 now has G.INP as of this morning so he'll be a happy bunny stats-wise. Hasn't done much for his line sync though, just a few extra kb on U/S
indeed.
I wasn't expecting miracles as my connection has been gradually, but quite severely affected by increased crosstalk.
However, as Bearer 0 Interleaving has now been applied at 16 DS & 8 US, the reduced error counts & the new way that G.INP handles things MIGHT help (a little)
I can at least claim that I appear to have the lowest DS INP value reported (in MDWS) for DS INP on a G.INP activated connection
