I've just switched to Sky unlimited and am trying to find out what sync speed I should be getting for my line's stats, as what DLM has resulted in me getting is leaving me distinctly underwhelmed.......
I have a connection that's about 700-1000m from the exchange, with d/stream attentuation of 26.5dB and noice margin of 7.8dB. However, I'm being synced at only 15358kbps, which I feel is a good 2000kbps below where my line should be.
My previous connection, on BT 21CN, was syncing at around 18800kbps with the same attentuation, albeit with a lower noise margin target of 6.8dB.
I think Sky's DLM has undercooked my line and the noise margin being a fair bit above the target of 7dB would seem to indicate this.
What do others think, and is there a calculator/chart somewhere that I can use to establish where my attenuation and noise margin should leave my sync speed on a Sky LLU exchange connection?
