Interesting , has your Target DS SNR lowered to below the default 6db,? as if it has dlm may have also applied the retx as a precaution to counter instability? That's what it did to my line, when it reduced the SNR to 3db, and then removed soon after but the Bras IP profile remained set at 92% approx I have had zen support chase BT on this they have in their reply basically admitted being aware of this "slight issue"
All 3 lines have always had DS Re-Tx (G.Inp) active and have always been "low profile".
DS target SNRM is 3dB on one of the PN 40/10 lines and the 80/20 BT line for as long as I remember.
The other PN 40/10 line has always had a considerably higher DS target SNRM, high subscriber density area, lots of cross talk, noisy line.
After the DSLAM's outage event on 10/12/19, all DS & US SNRM's dropped considerably and remained so until the next re-synch's.
The point I'am trying to make, brobably rather badly, is why has DS Synch/IP profile ratio changed to the value that would have been expected with Re-Tx high profile until very recently while all 3 lines remain on Re-Tx low profile.
Noted that there has been a further DSLAM event this morning at approx 02:00 hrs., all 3 lines have re-synch'ed to more or less normal expectation, DS Re-Tx low profile still applied, have not yet checked if any IP BRAS profile changes have occured.
