Over the last 2 weeks I have been experimenting with the ability to adjust the target SNR with my Draytek2760 on my ECI Cab.
A weeks running at the standard 6db target produces the following results:-
Synch speed 46.5Mb, average daily ES 7.
A weeks running at a 5db target produces:-
sync speed 49.4Mb, average daily ES 25.
A weeks running at a 4.5db target produces:-
sync speed 51.5Mb, average daily ES 33.
So, a healthy improvement in sync with a modest increase in error rate, and I am in control of the target rather than DLM.
I have previously tried all the well recommended Broadcom based modems, resulting in a typical increase in sync of 2 to 3 Mb but with a vastly inferior error rate of over 200 es daily.
