I have a question for the learned amongst you. Yesterday I moved from Sky 80/20 to BT 54/10 Now everything is as I expected except for the fact that my attainable downstream speed has dropped from 82 to 67. I would have thought that whatever profile I am on the attainable down and up would have remained constant...or have I got this wrong?
Thanks

If your an ECI Cabinet before you may have had interleaving enabled which gives a high attainable value.
Or if you are on a Huawei cabinet, since the line got changed yesterday you wont have G.INP enabled yet and the attainable will be much lower.
That would be my reasoning behind it anyway...

As above, perfectly normal.
Pretty much only those on fastpath/ECI retain the same DLM profile after an ISP switch.
Everyone else will see their sync and/or max attainable change considerably during an ISP switch.
I'm synced at roughly 50Mb. If I switched ISP tomorrow I would drop to roughly 35-36Mb.
That's the difference between "interleaving, 6dB snrm target" and "retransmission, 3dB snrm target.

I see. Yes I'm on a Huawei cabinet and I have a HG612 connected between the router and NTE and did notice that both G.INP and Interleaving were no longer active. Thanks.
