in telnet this command can increase your sync speed by setting your downstream margin lower, obviously there is a risk to stability with a lower margin, also I dont know yet how to make it go back to using the isp value, so to do that I assume could just set it manually again to whatever your margin is which I think looks like 15db now.
so you can telnet in 192.168.1.254 port 23.
port a1 set ActivateLine abort
port a1 set AnnexAForceSNRMarginDn 70
port a1 set ActivateLine start
that would set the snr margin to 7db, so 80 is 8db and so on. 150 would be back to 15db.
I got the info and the firmware many thanks for that, it is indeed older firmware but one that comes with a newer dsl code. Also grabbed a load of newer uk firmware for my other billion routers from the 2nd link you gave me.
The .55 firmware does also have the int coding gain settings as well. The problem I am looking to resolve is that SRA (seamless rate adaptation) seems to effectively crash on the version I am using.
