17a is just one of thoses beasts that we cant seem to tame.. wish we still could set it within X bounds, or it was more consistent in handing it over..

Well atleast I got the DLM looking at me, Its dropped me down from DLM 1 to 2 then 2 to 6.
Maybe it might put me on 17a, who knows..

I haven't seen any indication that the initial DLM testing period has any impact on the move to 17a. You're already on DLM-1 so I'm not sure a reset will achieve anything for you.


if i recall you didnt have the best error rates before you went 17a, what were your CRCs averaging?




Anything from about 0.5 - 6 per minute. Typically less than 2 but we thought the DLM-1 limit was lower then though. I had some weird syncs before going to 17a, with reduced SNRM and increased error rate.

odd.. 

still trying to decided if i should resync and see it go stable *hopefully* or not..



im sitting at 6CRCPM, with the 15min counter sitting more at 7.4CRCPM


IIRC, thats pretty boarderline for DLM-1 which is rather concerning considering all the work that has been done on my line at this point..



@hitman, whats your spec looking like?

Yeah I think it's looking borderline. It seems like the error rate is consistently increasing. What's the error graph look like?

was giving it a few hours before posting so there was an actual graph to look at..



i do agree though, the rates themselves look to be to increasing.. on the graph its solid however.. (reasonably)

still.. it seems absurdly high for a connection thats 271M (electrically calculated) from the cabinet inwhich there has been fresh wire ran from the ETP, and the lead-in has been repaired.

Yeah, it seems to be consistent around 7/min, which seems quite high given that there doesn't seem to be anything wrong with the line.

Time to downgrade the firmware I reckon!

yep, popped out for a little got back and in frustration (6 hours of uptime, and nearing 8CRCPM), forced a resync.


attenuation went up to 6db, SNR settled at 12db.






not sure if the drop in speed could be attributed to the slight drop in errors (this is an hour into being synced)


as the gf is home (and catching up on the fact that we have had no landline for 3 weeks), will need to wait a little till i can downgrade the firmware.


one thing that does stand out to me though, im seeing my attenuation range between 4~6db over the 4 different fritz's i have had on the line at this point...

Now that my line problems seem to be sorted and I have crawled my way back from DLM-8, do you guys think I might have a shot at 17a?

One thing I don't like is the sharp dip in my spectrum at around 200.  What could cause that?

that sawtooth at 200 is pretty impressive.. crosstalk ild say.

at 7db attenuation, its border line for what we can figure, but a shot at it none the less.

error rate looks pretty good for a 10db SNR too.

So just to confirm, what is the 'best' fritz!box 7390 firmware known?
