Maybe the issue is I had an ECI modem from the 12 June until replacing it yesterday with the HG612. Will give it some time.
Never had any experience with original BT issued ECI modems but I think they supported DS G.Inp, I'am sure some of the better informed patrons will correct me on this if I am wrong.
Have used a Huawei HG612 modem in the past, certainly a better bet for obtaining your line stat's, can even use DSLStats utility if you wish, lots of good information available on setting that up on the forum.
From the extended stat's you have provided it looks like you have a good low noise line, the ES's, SES's & CRC are currently very low or non existant.
When DS G.Inp finally comes along you will be able to determine if the profile applied is high or low, look at the
Bearer 0 INPRein parameter, 0 = Re-Tx low profile, 1 = Re-Tx high profile.
Low is best meaning that your line DS BRAS IP profile should be approx. 97% of your synch. speed as apposed to approx. 92% with high profile, ie., higher data speed, should default to low profile but doesn't always.
Again, some of the better informed forum patrons will be able to offer more detailed information on the line stat's you have provided.
In the mean time I would sit tight and give DLM a chance to sort itself out.
