Hello everyone,
As many of you are aware, I am on BT 20CN with BT's horrible DLM system! Now, here's what happened and why I am frustrated: I connected yesterday (03/06/12) at a sync speed of 6784Kbps at an SNRM margin of about 6.5dB (I connected at about 8PM). The connection stayed up all night dropping to a minimum SNRM of about 4dB. Great I thought! Well no, because at about 6:35AM, the connection dropped and synced back at an SNRM margin of 10dB due to DLM increasing the target SNRM to 9dB.
What I would like to know is, why did DLM increase the target SNRM? The connection didn't drop once during the night and it was up for about 9 hours, the error seconds count was 50 when it disconnected, hardly any. The CRC error count was low as well (I don't have an exact figure but it was pretty close to the error second count). There was one severed error second but I am pretty confident it occured because the connection dropped. So, why did DLM increase the target SNRM?
Thank you.
