Internet dropouts - what is a good snr for a G.fast line?

[sg19]

Hi,

Apologies for the post, but we're having near-daily internet dropouts, and I wasn't able to find much info on what constitutes a good snr for a g.fast connection.

The error is the logs is

"03:10:32, 08 Apr. WAN connection WAN2_INTERNET_PTM disconnected.[ERROR_NO_CARRIER]"

- seemingly indicating the line has dropped, but it reconnects within a minute or two, at full speed -

"03:12:19, 08 Apr. DSL Link Up: Down Rate=329289kbps, Up Rate=49399kbps; SNR Margin Down=13.7dB, Up=15.4dB"

We're approx 60m from the cab. We have no dial tone but are on a plan without a phoneline, so I assume that's normal (and hard to test the line quality!)

I was hoping to understand if we are in a reasonable noise range, and if we are, any ideas on what could be causing this?

Thanks

so I may contact CS/BT to look into it more in the future

Not BT with whom you have no contract.

Just CS then. What would a good SNR be for a G.Fast line @330mbps ?

Thanks

Depends what the maximum data rate is.

NM is 6dB or 3dB on a v. stable line (but I'm not sure if that's applied to G.Fast) unless the sync speed is hitting the max speed that that BB mode is physically capable of (330 Meg on G.Fast) in which case the NM is increased accordingly.
