And what is the sync rate? If much lower than the 58832 then this would explain the high SNRM.
# xdslcmd info --stats xdslcmd: ADSL driver and PHY status Status: Showtime Retrain Reason: 1 Last initialization procedure status: 0 Max: Upstream rate = 16486 Kbps, Downstream rate = 48192 Kbps Bearer: 0, Upstream rate = 16483 Kbps, Downstream rate = 34999 Kbps Bearer: 1, Upstream rate = 0 Kbps, Downstream rate = 0 Kbps [snip]
The maximum attainable rate is currently lower than the line rate so it would seem your line conditions are changing over time.
As the modem is unlocked have you considered monitoring with the DSLstats program to see what it's doing?
