It sounds like straw grabbing, but have you tried a different make of cordless phone ?

I can vaguely remember years ago having an issue with an ADSL line, which was due to a Panasonic cordless phone ( the biggest issue being that the line in question was in a Panasonic shop, so they wouldn�t try something else)

There was mention elsewhere of �double filtering� the phone, did you try that ?

Hi,

Funnily enough, the new phone is a Panasonic!


Yes, i did try the double filtering but made no difference.

The previous phone was a Siemens Gigaset which admittedly, is the one we were using for a few years with no apparent problems.

I am going to return the Panasonic, so maybe ill try another Gigaset.

I thought you�d mentioned it was a Panasonic elsewhere ...

I hope this change sorts it, and keep up the commentary.

Well, that was short lived.

Just plugged in the Gigaset and whilst CRC and ES are the same, FECS again took a massive jump, after being relatively stable after a few days.

As of around 8am today they were at 338583224.

Before plugging the new phone in at 12.40pm they were 338584269.

Phone been plugged in for 10 minutes and they have jumped to 340307809!

Thats just over 1.7M in 10 minutes, 172,000 per minute and 2872 per second!

I just don't get it.

As i said before, we had a Gigaset phone for years without it affecting our speeds/internet etc.

Something has got to be wrong somewhere!

Hi Alucidnation

Is it worth you summaries everything you have tried and what was the results as you have now tried several scenarios and not sure if results were consistent with each attempt.

Ok, i'm out and about at the moment so i'll give it a go this eve.

Righto, in that case, my guess is that you have a very minor HR fault somewhere .....

Funnily enough, i have been reading up on FEC errors and a couple of people have had similar.

I have reported this to my ISP and they suggested another engineer visit which they have arranged for tomorrow morning.

As of now FECS are at 341393522 from 340307809, and that is with the phone unplugged after my post at 12.55pm, and that's just over 1M in just over four hours.

One thing i have noticed is the face plate of the new 5C filter is not all that firm as when i plug in and out it has some movement.

I haven't taken that off and tried the test socket as i didn't want to keep resetting the modem error stats.

When the next bod comes to do an SFI, ask them to put their tester into manual sync, then plug their butt in at the same time whilst watching the error counter ....

It might be the only evidence they can chase.

Maybe wacking the gain up on the TDR might show something.

If they start saying �but the PQ test passes� maybe politely suggest they check with their senior engineer...... many HR faults don�t show up on a PQ test.

Am i reading this correctly?


But anyway, thanks for the advice!
