Sync speed stayed the same its still at 13987.

Latest:

Latest 15 minutes time = 2 min 40 sec
SF = 9874
CRC = 911
LOS = 0
LOF = 0
ES = 127
Previous 15 minutes time = 15 min 0 sec
SF = 55325
CRC = 4444
LOS = 0
LOF = 0
ES = 733

My SNR started about 8.8 at around 6pm and has sunk to around 7 now.

I'd consider 1 ES in at least 1 min to be OK. You are getting 1 ES per 1.2 secs.

Oddly enough - its stopped now.

edit: had to resync as I was testing the phone in the test socket ( i think there is still a bit of noise on the line but its quite feint)

Still getting lots of ES and CRC's according to the DMT tool and at around 4pm a loss of sync - re-sync to yet lower speed 13500 that wasn't initiated by me

What's the quiet line test like now?

Did you go back to using the 585 v6 router?

Got another DG834GT

Been monitoring the error rate, getting lots of spikes like this one - are they anything to be concerned about? ES are roughly the same

Had a voice engineer look at the line again today - noise has gone but till low sync. Am I right in thinking I need an SFI engineer to look at this?

What's the situation with your vivaciti ticket: has a line inspection by an OR SFI engineer been suggested by vivaciti on the basis of your low downstream sync? Plenty of dropped connections per day would certainly warrant a SFI check for sure�

Hi
I logged another call with PO on thursday as this was suggested to me that this was the way to go. BT did somthing on friday (dont know what) and any remaining noise on the line seems to have gone. Now either by luck of design the error rate for last night was well down and it held sync but the sync hasn't increased.

Vivaciti suggested raising the target snr to 9 - which would make sync worse .

These are my current tg585v7 stats (xilo/uno - TT partial LLU):

DSL Type: G.992.5 annex A

Bandwidth (Up/Down) [kbps/kbps]: 1.022 / 13.839

Data Transferred (Sent/Received) [kB/kB]: 0,00 / 2,00

Output Power (Up/Down) [dBm]: 12,0 / 19,5

Line Attenuation (Up/Down) [dB]: 20,5 / 37,0

SN Margin (Up/Down) [dB]: 10,5 / 6,0

With your downstream attenuation you should really be getting an extra 5Mbps on the downstream sync - vivaciti just talking about raising the sn margin (?) to 9dB does seem rather unhelpful...
