Hi
ASUS DSL-AC68U
Oops :/ Unfortunately whilst Asus routers are usually very good.. the modem chipset in that particular model wasn't and it has caused problems for quite a lot of people. Anyhow damage done and moving on...
I can see a depth of 4 for the Downlink and 2 for the Uplink.
May I just check that is the depth as it seems rather low? Although saying that I'm working blind and not sure if the line is on a Huawei cab and has benefit of G.INP or not.
Possibly more useful in your case is the INP value in Bearer 0 and the delay.
INP=3 & Delay= 8 which indicates the Openreach profile of Interleave low. Anything above that is Interleave High.
Given the problems I had at the beginning with Origin and the router, could that have caused the DLM to be stuck?
It certainly could have caused the line to be banded and/or caused Interleaving & Error Correction to be applied.
- Banding is not the same as 'stuck'.
- Banding is an artificial speed cap deliberately placed on the line which ensues in a higher SNRM to give the line more stability.
- Banding may also be referred to as 'capped'.
what do I need to check, in order to have some evidence that the DLM "might" (? or is?) be stuck?
Obvious signs of banding are that there is more than 6.3 dB SNRM immediately after a resync and that the sync speed will not go above a certain rate and is the same speed each time you sync which usually ends in 998. I've given the Interleave Low params above.
TBF it is quite often hard to spot all the signs and some people assume their line is banded, when its not. Reading line stats can be a black art... you have to look at several parameters and even then sometimes relies on gut instincts that comes from years of interpreting the data, simply because something looks 'odd'.
If you are new to linestats, then it's best posting full stats (telnet data) and let someone else look as it will give us a lot of the info that we need.
hence Origin might not even bother asking OpenReach to put me on a NGA speed profile.
Depends who they are using to provision your line. Origin have a weird history. They were very good - then got got caught up in the Digital Region Fiasco which caused them a lot of damage reputation wise.
Then they picked up their socks invested in the company and started using a combination of their own network, Plusnet and Vodafone and for a while all was good again. CS was good and calls answered promptly, they invested in a new call centre and took on new staff it all looked rosy.
Then they stopped using PN white label and moved most lines over to Vodafone... who unfortunately suffered a lot of congestion problems. Origin users were generally deemed to be more tech savvy than the bog standard VF user and more likely to notice.. so complaints ensued and the company started getting a bad rep again due to the VF congestion. They weren't the only retailer who ended up having to drop VF wholesale, but I think damage may have been done and as the customer base decreased I think they may have started to struggle financially and had to lay a load of staff off yada yada.
So..... back to your question. I believe they are now using TT wholesale, which does actually have a pretty decent backhaul.. but they do use the standard profile by default.
Years ago Origin told me that because they were also an Openreach customer they could change this directly when they were VF resellers. Not sure if that also applies now they are with TT, but worth a try and won't harm in asking.
Should I ask Origin about what NGA profile they use
See above. If your line is provisioned by TT wholesale then it will be Standard.
The reason I went into detail above....
if Origin are still also direct customers with Openreach because they also own their own network, then they should be able to run a GEA test on your line and check you DLM profile.
Can a disconnection from the DSL port - remove the DSL cable from the plug, as hinted here https://forum.kitz.co.uk/index.php/topic,24069.msg405571.html#msg405571 - for a number of hours, cause the DLM to get unstuck?
No this never removes banding. Artificially rate limiting is the only way we have ever seen some success if the line has been banded or interleaved.
Re the other thread, there is something weird going on right now. My line (and a couple of those in the thread) shouldn't have been interleaved according to theory but they were. Based on what you've said I don't think your line is 'stuck'.
If I reset the router -
Depends on how many times. Just a couple should be fine.
Does high interleave depth mean lower speed, higher pings, both? I think it does, but I would just like to check.
Yup.
