I still don't think it has been stated here with certainty by someone in the know - what profile is used on Essential Plus on a line which has no issues?
3008/800 fast path if your line can't handle it, then you get, 2496/640 interleave maintenance profile if your line can't handle it, then you get, lower profiles as found in the FAQ in this forum
been stated is correct. Default is 3m al1. Minimum is 672k.
