Dropping PPP Session - Seen As An Error by DLM?
« on: March 05, 2019, 03:36:54 PM »

Hi, sorry if in the wrong section...

I have an FTTC line installed by my work, i game on the connection and have noticed sometimes when it reconnects, it authenticates to my ISP via Manchester, which adds about 15ms to my pings (seen via a tracert) (total about 25ms).

If i redial the connection a couple of times, it generally will then auth via a london server (seen again by a tracert, around 9ms ping times). My question is, will this redialling be seen as a dropped connection by DLM and ultimately have it act on my line (slower speed/interleaving?). Just a bit confused how the DLM see's the errors, when connected to my ISP or having the line drop sync to the local cab/exchange. When redialling, i am just killing the connection from my ISP end (i have admin rights to manage my clients who use this so can kill/suspend/terminate the line directly) until it auth via london.

thanks in advance for any info!

DLM won't act if it's just the PPPoE link.

If however you are using a modem/router combined unit and you are dropping the xDSL link at the same time as the PPPoE link then DLM counts the xDSL resyncs.

So as CarlT says, no in this instance.

Seeing as the subject line includes the words "PPPOA dialup", I need to ask if the circuit in question is FTTC VDSL2 (ITU-T G.993.2) or ADSL{2|2+} (ITU-T G.992.{1|3|5})?

If it's the latter, then I need to move this thread.

Hi, sorry it is FTTC/VDSL2 (was just using the wording from my Draytek).

I am using a Draytek 2860. i don't beleive i am dropping the xdsl link? i do nothing my end, just login to my isp portal and kill the connection and it reconnects within a few seconds.

If you are just killing the PPP session and not the sync then you are golden.

Do the dreytek's stats show a sync uptime?

Should be easy enough to tell from the sync speed, if it doesnt change at all after your ISP connection killing method then you are fine, DLM has no knowledge of PPP session dropping and doesnt care.

doesn't appear to show a sync time. I could just click the "Drop PPPOE" on the Draytek rather than killing it at the ISP end if that is potentially safer?

Indeed, dropping the PPPoE session on your router would be easier, whether its safe depends on what happens when you do it... I would observe both, taking note of exact sync speed up and down before and after (I guess this might not work if you are at 79999 & 19999 or whatever FTTC maxes at) if zero change either is fine and use the most convenient.

My only caution would be with doing it on the draytek, I have no experience of them so have no idea if the GUI could do something stupid like cause a resync on this command, easy enough to find out.

thanks. doing it from the ISP end doesn't reset ES errors in either direct etc so would presume the xdsl sync has stayed online?

Seems like a safe assumption.

Dont get me wrong about doing it on the draytek, it should be fine too, but its worth checking.

That's no problem at all. Thank you for confirming.

I'll just modify the subject line to stop anyone else being as confused as me.

And a belated ‘welcome’ too, spaace- if I haven’t already done so.
