Can anybody tell me where to find the source material for the error thresholds for DLM line categorisation. I notice that the ones on this site are quite different from the ones on the BT patents. Has there been an update of BT's info somewhere? Any insight as to what is going on with the numbers would be helpful. Thanks.

The information used to be available online. Almost everything disappeared after/during the ASSIA court case.

Last known figures for MTBE and MTBR are here

Not sure what you mean about source material.. the information is/was given to ISPs by BT in their briefing reports.
Last update that I'm aware of was for NGA DLM in May 2015.
