Putting that aside, I am concerned with the sudden drops in the SNRM this morning. Do they correlate with any electrical activity from within your domain ("The Aerie")?
Hi b*cat,
They do indeed
DIRECTLY relate to land line phone calls that Mrs. Eagle made (dialing out, not answering).
It appears that whenever any handset is picked up, SNRM drops significantly & rises again as soon as the handset is replaced.
I have today tried adding brand new, previously unused filters that came with previous ADSL modems.
The additional filtering had no effect whatsover in resolving the dropping SNRM levels.
These events have not all been captured in the modem log/graphs as data is currently only captured every 2 minutes.
I might increase that to capture data every minute.
I currently just have 3 telephones connected:-
1 is plugged directly into the "new" SSFP AT the "new" NTE/5 Master socket (downstairs).
1 is plugged in upstairs via a double adaptor at what is now an extension socket (was the master socket prior to FTTC being installed).
This extension is hard wired from the "new" master socket along a spare pair in the braided cable mentioned previously (connected by the FTTC installing engineer).
1 is plugged in downstairs at the end of another extension, from the upstairs double adapter.
I have disconnected the Sky box & FAX machine, so the total REN is now 3, but SNRM still drops immediately a handset is lifted.
During the previous documented troubles I checked all this as a potential cause.
I never noticed SNRM dropping during phone calls.
I have only noticed this phenomenon very recently.
It may have coincided with the profile switch to 17a, but I can't be 100% sure.
CRC errors are currently almost 2 Million, following 1 day 12 hours broadband connection time.
My throughput speeds do NOT seem to be affected during phone calls & the FTTC connection is maintained despite dropping SNRM levels.
I wonder if the filtering in the SSFP is "faulty" (could lightning have damaged it?), or simply not suitable for the higher frequency 17a profile.
Am I correct in assuming the SSFP filtering should work both ways?
i.e. it SHOULD stop the broadband messing up phone connections & SHOULD also stop phone connections messing up the broadband?
Could
THIS be a pointer to the issue that has attenuated my sync/throughput speeds for the last few months?
A graph of now around 19 hours worth of connection time is attached.
The most recent SNRM drop was at around 8:30 this evening, when I simply picked up the handset that is plugged directly into the SSFP at the "new" master socket, with just the dial tone until it cut off.
Paul.
