It would be nice if we could have stats obtained using telnet, similar to mine posted earlier. Those make it incontrovertible what is enabled, as Bearer 1 is either present or absent.

Yes the stats from the OP's Draytek router are a not very clear, particularly the Near End / Far End confusion and not showing if Bearer 1 is active. However the first stats on TalkTalk on June 20th show there is no ReTx active. I think we can safely deduce that Downstream G.Inp has been activated in the latest stats on June 25th.

Another 1 today.
I'm on my desktop PC later I'll use the search function and give you a dozen recent examples. From my mobile phone not so easy.

There's even an example of an OpenReach engineer performing 4 DLM resets in a row to try remove interleaving and wondering why it's not working.

If you switch ISP on a Huawei cabinet the line defaults to interleaving.
If you have a DLM reset on a Huawei cabinet the line defaults to interleaving.

With an ECI cab both those events put the line on fastpath.

In reply to a post by Ixel:

They have G.INP I believe. See line 12 (ReTx). From what I can see downstream is G.INP (I believe the columns are swapped).

My mistake. Retx is indeed enabled already.
I do that all the time with DrayTeks. So confusing how they swap near end/far end for different parameters.

The OP and the thread I just posted were both ISP migrations causing interleaving to be applied.

Here is an example of a DLM reset that's just been performed.

The default Huawei line profile "Downstream low interleaving - Upstream Error Correction Off" has been applied.

I looked back at my own line (Huawei cabinet) history a few days ago, as I had a few months banding that was resolved by an engineer reset.

At that time I clearly wasn't surprised that my line stats minutes later showed interleaving on!

My apologies therefore.

Oddly however, I also found this Nov 3 2017 ISPreview article. I wonder if we are both right? A reset gives interleaving as you say, but if a new (intial FTTC on that line) connection is made perhaps it starts on an open profile?

What do you think?

In reply to a post by RobertoS:

On migration between ISPs on the same underlying provider, basically BT Wholesale, TalkTalk Business and Vodafone, DLM is not reset. So if a line is on interleaved before migration it will stay so.

Not seen that on 3 migrations (different lines) all BTwholesale platform ISPs but each time the DLM was reset, and started again. (In two cases, it was beneficial, including mine).

I don't see Bearer 1 in use on my HG612 with G.INP enabled if you mean the sync info line?
Max: Upstream rate = 9437 Kbps, Downstream rate = 60304 Kbps
Bearer: 0, Upstream rate = 9441 Kbps, Downstream rate = 62153 Kbps
Bearer: 1, Upstream rate = 0 Kbps, Downstream rate = 0 Kbps

Bearer 1 shows with zero sync because the speed is 200bps. (Note, not Kbps). It therefore rounds to zero .

When G.INP is not enabled that line is absent.

Thanks !

Update on BT support: I called BT mobile today and spoke to a chap from the Warrington call centre to ask for my PAC codes.

He offered me some really good retention packages and actually went to the time to listen to my complaint about why I left the broadband service in the first place. In the end I still requested the PAC codes but the chap I dealt with was possibly one of the most helpful I have ever dealt with on the phone.

So they can do right at times and clearly some of their staff are geared up to be helpful.

Goes to show --- and I thought it only fair to report on a good experience on this occasion.
