Thanks gt94sss2. I'll keep an eye on the stats over the next couple of weeks and hope that G.INP is enabled and will then go back to my ISP and 'discuss further' if required

G.INP took nearly 4 weeks to kick in here.

Yawn :-/

I'm still sitting tight and waiting for a G.INP miracle.

You might not ever get one, because of these:

That's quite a large amount of errors happening on the line, thankfully mostly corrected by the FEC process.

It might well be that DLM has made a conscious decision that your line is best corrected by old-style FEC+interleaving rather than by new-style retransmission.

Even though new-style retransmission also comes with a limited amount of FEC and interleaving, that retransmission can be overwhelmed if it sees too many errors. In such cases, falling back to old-style FEC+interleaving, with heavy-duty settings, is the best option.

Unfortunately, we don't know much about this scenario as we would rarely see it. That means we can't really tell if you have fallen foul of this, but it is certainly a possible scenario for you.

I tend to agree.

I looked at
Latest 15 minutes time = 10 min 37 sec
FEC: 19215 4
CRC: 1 2
ES: 1 2

and

Previous 15 minutes time = 15 min 0 sec
FEC: 38254 12
CRC: 57 9
ES: 3 9

and wasn't too happy. They aren't huge, but may be sufficient to rule out G.INP. I waited for other comments.

Thanks guys - I appreciate your time and explanations.
