I've had issues with my line recently with noise which caused sync issues on the router. This has now been fixed by Openreach but as you might have guessed this caused DLM to go nuts to try and stabilise the line!
Here are my line stats
DSL synchronization status:
Upstream line rate (kbit/s):
Downstream line rate (kbit/s):
Maximum upstream rate (kbit/s):
Maximum downstream rate (kbit/s):
Upstream noise safety coefficient (dB):
Downstream noise safety coefficient (dB):
Upstream interleave depth:
Downstream interleave depth:
Upstream line attenuation (dB):
Downstream line attenuation (dB):
Upstream output power (dBm):
Downstream output power (dBm):
My question is this, Over the last week there have been a couple of DLM managed resets early morning which seems to be normal and each time the Interleaving depth has been reduced. So I guess i'm answering my own question but the fact that the interleaving depth is being reduced means that the line conditions are recovering as far as DLM is concerned and then it will hopefully start increasing the bandwdith?
