ADSL2 line training - what to expect?

I am now seeing an increasing count of RX CRC errors, is this normal during the training period (i'm guessing training involves turing the wick back until the CRC errors stop?)
My Line stats currently show:
ADSL Information ( ADSL Firmware Version: 2471201_A)
ATM Statistics TX Cells RX Cells TX CRC errs RX CRC errs
484780 13091268 0 11869
ADSL Status Mode State Up Speed Down Speed SNR Margin Loop Att.
ADSL2+(G.992.5) SHOWTIME 443928 15768266 7 27
Which is a slightly slower sync speed than yesterday

It is possible that the default nose margin has increased from 3dB to 6dB
You are leaving the router on all the time I assume

The error rate is very low so no problem there
I would just leave it alone until after the training period then you can ask for the upstream to be uncapped

I wouldn't exactly call the error rate low:

If you aren't having any speed problems, I wouldn't worry however.
I would expect a maximum of sync speed of about 17Mb/s and a maximum download speed of about 16Mb/s.

On that basis I considered that the error rate was low
On the other hand - if the line was interleaved - I would agree that they are a bit high

Interleaving is currently off so that's probably the reason you're seeing the errors. I'm sure putting interleaving on would rectify that.

Should I request that interleaving is enabled on my line now I have ADSL2?
I see alot of pages that "stall" and the error rate continues to rise.
Should I wait until the training period is over?
What's the deal with the upload uncap?
Thanks.

I've placed the order for you, should complete tomorrow. The upstream will be uncapped, and it will turn interleaving on (though at present it's on 'auto' and turned on).
Hope that helps.
