Line Rate Data

Having been activated for a few days, the sync seems to have dropped. Is this normal? I did unplug the modem yesterday afternoon ....

In a word, Yes.

DLM is likely to have reacted to errors on the line (or resyncs) and added interleaving & FEC (Forward Error Correction). The FEC process steals some of the ultimate bandwidth.

Thank you. Does it go back up again?

(not that a couple of mb really matters, just interested)

I've had both happen.

One line, where the errors were constant, and probably came from crosstalk with the neighbours, kept interleaving.

The other line gained interleaving after a line fault, then lost it 3-4 weeks after the line was fixed.

Mmm. Speedtest dropped to 65mb this evening from 76mb originally and 74mb over the weekend.

And the profiler automatically dropped again this morning to 60mb.

Off to call Zen I guess as that isn't okay.
