Once the retransmission changes from high to low, is the BRAS immediate to change the rate or does this take a few days or so?

I expect you'll find out soon enough without stressing about it.

This is the sort of situation where you cannot influence or affect what is going to happen. If you cannot make any input then there is no point in trying to second guess things as whatever is going to happen will happen. The only option in cases like this is to lie back and think of England.

This is good advice, think of your heart as stress causes an increase in low density lipoproteins (LDL) and that can ultimately cause angina which can then lead to a heart attack. Get a non-fasting lipid test with a liver function test every so often if you are someone that stresses. If your non-high density lipoproteins level is consistently above 4 consider speaking to your doctor about statins to manage it as you are at a greater risk if you do nothing.

Exciting news this morning! - The retransmission has gone from high to low and the BRAS has also increased accordingly! So this took a total of 6 days ... amazing!

Should I leave the sync throttled to 40 mbps for the next few days or take it off immediately now that the retransmission has gone back to low?

I would leave it. Did the max rate change at all?

Hopefully the DLM speeds up now and the SNRM target starts dropping every couple days.

Yes it's gone down a little to 54mbps from 55mbps but the SNR has gone up to 11 from 10 if I remember correctly (whilst being capped)

Currently:

Bearer: 1, Upstream rate = 0 Kbps, Downstream rate = 0 Kbps

Down Up

How long should I leave it for?

Restarted the FTTC modem and it looks like the line is still banded/capped even though the retransmission has gone from high to low ... latest stats:

Anyone know how to get the line unbanded/uncapped?

What deal are you on? The 54999 may be a pointer that your ISP system thinks you are on something like a 55/20 deal

80mbps down/20mbps up

I've been in a similar situation before, see my stats on the OP under the title: April 2017

There is no 55/20, only 55/10

The only Openreach FTTC package that allows a line to sync above 10Mb on the upstream is 80/20. Therefore the fact the OP is syncing above 10Mb/s upstream means he must be on 80/20.

Providers don't have a way of manually capping the upstream or downstream sync rate, only Openreach can do that via the package limit or DLM banding. So the line must be banded.

Plusnet used to sell 40/20 many years ago, but they ordered the 80/20 product from Openreach and rate limited the line at the BRAS. So a good line on that Plusnet package would sync at 80/20 but downstream throughput was limited to 40Mb/s.
