I guess it's worth mentioning that BT don't use ATM on VDSL2 so PPPoA doesn't apply. BT use PTM instead.


PTM ? I thought BT used PPPoE on WBC FTTC lines?


This is directly from the modem's stats on my VDSL2/FTTC connection:-

"G.992.3_Annex_K_PTM"

The modem's GUI also reports:-

Mode: VDSL2
Traffic Type: PTM

MTU Size 1454

So what's the significance of 1454? That's what my ZyXel was set to until I changed it yesterday.

Dunno, but that seems to be what it's own line analysis chose. I may have a look at the Plusnet Netgear some time and see what that is set at.

My broadband basic info/help site - www.robertos.me.uk
My domains,website and mail hosting - Tsohost. Internet connection - Plusnet Value Fibre FTTC 80/20 trial.

PTM is just the transfer mode the modem is using to communicate over the DSL link.

The HH connects to the modem and authenticates using PPPoE.

If it's the same as my Netgear WNR 1000v3 as supplied by Plusnet for my FTTC connection, it will be 1492.
