Interleaving - how long does it take to remove?

(1/16) > >>

Jon21:
In the early hours of Friday morning, my connection dropped and came back up with interleaving applied. I think it was because there was a large burst of ES on Thursday. Not sure what caused it, I've gone back to using a Draytek Vigor 130. I've also replaced the DSL cable from the master socket to modem. The RJ11 end was looking a bit suspect, sheathing had broken at the crimp on the plug. Ordered another one from Run-IT-Direct and the build quality seems to be improved compared to the old one. Was just wondering how long it takes to go back to Fastpath?

It all depends. 

My connection has had interleaving applied for the past 14d after a burst of ES (400 or so) in a couple of hours period. 

Way below the 2440 max allowed in the day but must have hit some unknown limit perhaps per hour.

I have had a maximum of 5 ES/hr since normally 0/1 with 10 CRC/hr. 

No idea why it is being reluctant to remove this time in the past it used to take 3 or 5 days maximum but the last couple of times it has happened (storms) it was 10d and 12d iirc.

I'm also on an ECI cab which isn't great. 

I may try switching off for 30m or so and see if a resync will wake up the DLM, 14d is getting ridiculous.

broadstairs:
Not wishing to upset anyone but I've been interleaved (and capped at 60mbps) now for nearly 4 years on an ECI cabinet, even BTOR have no idea why!

All you can now do is make sure your VDSL2 connection stays stable for next 2 weeks with out any forced resyncs and very few errored seconds per day like under 10 good luck.

Chrysalis:
Ideally we need to see ES rates over a period of time.

To ktz392837 I think 5 ES/hour "whilst" interleaved is not particularly low.  Bear in mind the green threshold is probably very low.  Green on Interleaving will be way way lower than green on fast path.

Also the recovery period increases if you have more incidents, I dont know if it ever reverts back to a 2 day recovery e.g. if you have no incident for a year, but the recovery time will increase if it has repeated incidents.
