What modem/router FTTC with adjustable SNR and Fastpath etc?

[link to this post]

Hi there. I used to have a modem with normal ADSL that you could set the desired noise margin it would use to conenct. Also you could force it to connect via fast path or varying degrees of interleaving at your choice.

Which modem/router does this, but works with BT FTTC ?

Many thanks.

DLM doesn't like it if you change the noise margin. It likes to control that itself.

Same answer!
On FTTC The DLM alone decides whether interleaving should be applied or not.
It may apply it after some disturbance and then after extensive monitoring it may remove it...or it may not.

Neither you nor your ISP has any ability to over-rule the DLM in this respect.
So you cannot request your ISP to either switch it fully off or on.

Openreach specifically state they don't want you altering the SNR. In any case, I tried it with an unlocked HG612 and it made a complete mess. The reason possibly being that while on ADSLx the upstream band is below the downstream, on FTTC they are split into sections and the sections alternate.

Discovery Phase (Initial) Band Plan
US: (7,32) (871,1205) (1972,2782)
DS: (33,859) (1216,1961) (2793,3970)
Medley Phase (Final) Band Plan
US: (7,32) (871,1205) (1972,2780)
DS: (33,859) (1216,1961) (2793,3970)

You can't affect the interleaving except by having a clean line or reducing your sync speed, which will reduce errors so help with the interleaving. Someone has managed to do that, I think it was with an HG612. What is yours?

Given a stable line with low errors interleaving does turn off automatically after a few weeks. I managed to get it turned on last night frown
