I've been looking a bit further and the SNR seems to be stable.
My cabinet is <50m away so I'm a bit surprised that my DS SNR is down to 5.7db.
SNRM on FTTC is not treated the same way as on ADSLx. In particular it is not, so far as we know, used to improve stability. It looks as though it is always set at 6dB at sync time.
Stability is achieved through various depths of interleaving if Fast Path proves unreliable, and speed banding if even that doesn't sort things out.
