I am still attempting (after many months) to get to the bottom of why my 800m or so connection is quite unstable & can only sync at around 28Mb to 30Mb.
I have recently had a few days worth of an issue where downstream SNRM levels dropped dramatically when the phone (in the test socket via a dangly filter) was in use.
Even when the phone was not in use, DS SNRM levels dropped dramatically to 2dB or less.
As using the phone caused a further drop in DS SNRM levels, one occasion actually caused the connection to re-sync 4 times within a 10 minute phone conversation.
DS SNRM levels now appear normal & steady again, even when using the phone.
My question is, do any of you who monitor "Ongoing" stats via the Windows graphing scripts see fluctuations in DS power levels.
The available scripts do not currently graph power levels, but I am working on an update that will do so.
In the meantime, this is what my power levels look likethis :-
BE 6 Day Power Levels
In comparison, any other users' connections I have seen look like this:-
Other User 6 Day Power Levels
While typing this message, my connection re-synced at only 21172 k - The phone was not in use at the time.
DS SNRM has shot up from 6.1dB to 9.9dB accordingly.
If anyone wants to send me their modem_stats.log for me to graph power levels, please send me a PM including an email address, or post the whole modem_stats.log somewhere that I can download it.
Within a few minutes, DS SNRM had dropped to 2.5dB & just picking up the telephone handset caused it to jump back up to 10dB.
Does this suggest a particular D-side or even a cabinet DSLAM issue to any of our erstwhile engineers?
