The SNRM will always fluctuate. On ECI the median SNRM is 6.3. My goes down to 4 on occasions. By definition itís not fixed

All I can say is it hate FTTC!

Todays stats - Seem to be way below the max ES Count p/day?

Based on what?

As mentioned above the ILQ green figures on kitz wiki pages are no longer accurate.
You need to be considerably below the figures quoted there.

It is possible that you will have to cap your downstream sync rate to lower the ES/FEC numbers enough for Interleaving to drop.

If it's still interleaved after 8 days then a cap of 40Mb for a few days should work.

Hi j0hn,

Do you know how to cap based on router?

It will be either...

Code: [Select]
xdslcmd configure --maxDataRate 40000 20000 100000

Or

Code: [Select]
xdslctl configure --maxDataRate 40000 20000 100000

I can't remember if the zyxel uses xdslcmd or xdslctl.

That will set a cap of 40 down / 20 up / 100 combined (up and down).
Effectively it's a cap of 40Mb on the downstream only.

That's usually enough to shake sticky Interleaving. My line would never drop Interleaving without a cap despite being well below the assumed ES limits and that was years ago. The thresholds appear to be even stricter now than they did then.

For my ZyXEL VMG1312-B10A it's:
adsl configure --maxDataRate ***** **** 100000
DS desired rate followed by US desired rate (or max.) in Kbps as j0hn has said.

In my case entered from command line after logging into modem via Telnet, Win 10 OS.
I believe application of a modem cap instigates a re-synch, have never tried.
The cap won't survive a modem re-boot, if still required will have to be re-applied.

It does definitely cause a resync and as @tiffy remarks it will not survive a reboot.

After applying you need to forget it for a week or so.

Morning All,

So interleaving has now gone! However I fear it will be back shortly ES at 90! for 8 hours..



Should I see if interleaving get's reapplied and if so put downstream limits via router?

Just to clarify, did you actually apply a DS modem speed clamp or was interleaving removed by normal DLM action without clamping?

Hi tiffy,

No modem speed clamp was put on, interleaving was removed by normal DLM action without clamping :).

90 in 8 hrs should be fine if your on a speed profile

Well ES has risen from 90 from original screenshot to looking around 300 or so a day.

I wouldnít be concerned at 300 the original limit was 2880 that @kitz published although itís considered to be less now before DLM acts on speed profile. But its well over that. I have around 500/day on both lines that remain on fast path.
