Yes ECI. CRC normally higher than ES you show CRC. On my circuit 24hrs. CRC 561 ES 129.

I believe DSLAM will react to it in 7 days or less if its too high?

No thatís not right. The DSLAM isnít the issue itís the DLM and it acts in 24hrs but NOT on those figures! And you keep quoting CRC Not ES.

And in any event you canít stop it !

Read here.

But the 2880 ES fig is lower now but we donít know by how much.

And you keep quoting CRC Not ES.

Every image he's posted has both CRC & ES.
If viewing on a smaller screen you need to scroll to the right of the images to see the ES figures.

I believe DSLAM will react to it in 7 days or less if its too high?

The DLM will apply Interleaving within 24 hours of breaking the ES threshold.

We have no idea what the limits are now but to my eye you have nothing to worry about at the moment.

Sorry if it's not as visible, here's txt at this current time  :).

Not change to interleaving so far so it might be within the okay, i normally see it go wrong with 3 or 4 days of a reset but this was done by itself no engineer needed to bring it back off interleaving.
