James,
[First apologies to everyone for asking the question then not following
up on the answers until now - I went off line for a while.]

Re BT specifically (and again my info is outdated and may be mis-remembered)
the 20C network used L2TP, and I think it’s an option on 21C for handoff to
smaller ISPs. Should all be in the SINs somewhere?
I work in the UK ISP sector. I can confirm that L2TP is in wide spread
use for wholesale services by all major ISPs (except Liberty). I think
the real question here (unless I've misunderstood) is not "is L2TP
being used" but "is L2TP being used AND sequencing is being used
and/or enforced?" - is that understanding correct?
Yes.
In that case - sequencing isn't used for BT Wholesale services.
[BB] Thank you. It sounds like you have some reason for your certainty
here. Can you elaborate on what makes you so certain sequencing isn't used?
Bob
Cheers,
James.
