Huawei HG612 supports vectoring.
I answered you a few posts up. No need to buy another modem. It may be installed on the DSLAM, but currently isn't enabled.

Yes you did and thank you  :) . I bought a new modem for its 35b capability which I might need later and to potentially also take over the routing functions on my network, however at present my trusty hg612 is still plugged in and still saying vectoring status 5 with no sync change since vectoring was enabled on my cab that I can see.

This is what my isp has said  "The current line profile that your service is connected to, I can confirm to be a vectored profile capable of up to 100mbps"

Unfortunately you have not captured the full number of sub-carriers. Profile 17a has 4096 sub-carriers ("tones"), numbered from 0 to 4095.

Anyone had any thoughts on how else other than screen shoting the vectoring status i can tell my isp vectoring is in fact not active.

The only thing i can think is to try my modem on someones i know it is and try their modem on my line but that is not an option at present.

I am not aware of any method other than showing the xdslcmd info --vectoring command and result returned.  :-\

Well after a bit of back and forth arguing vectoring was not enabled on my line and getting hold of yet another router the one provided by the ISP rolling out vectoring, getting the stats showing yet again vectoring is not enabled, then getting the stats from the same modem on another line that is vectoring enabled I have had a result.

"I have changed the vectored profile for this circuit.
The circuit is now showing a sync of 97.7Mbps down and 10.9Mbps upload."  (from 65 down)

Now I dont  know much about vectoring but I thought it was all or nothing and I have doubts it was actually enabled on my ISAM at all. What do you think?

Anyway, actual vectoring stats from a Huawei HG612 3B

That is quite clear, the Vectoring state: 1 line tells us that vectoring is enabled for, and active on, your circuit.

Here is the link that I use for the meanings of the various vectoring states.

Thank you yes I meant I had doubts vectoring was actually enabled before today when they were saying it was  :)

I had been waiting for state 1 to appear instead of 5 and today is the day  :cool:

Thanks for the new thread! Let me know if you want any further stats for your reference.

Your experience has proved that ISP support will tell you things that are obviously not true. Your line did not have vectoring enabled previously despite being told it was, but you got there in the end after a bit of an argument. Persistence can often get the desired result. :)

Bilbokitz your  upstream appears limited to 11 Mbps,  is that correct? Attainable  is almost 32.

Nice  result on the downstream.

Now I dont  know much about vectoring but I thought it was all or nothing and I have doubts it was actually enabled on my ISAM at all. What do you think?

You are right - vectoring should indeed be "all or nothing". In the sense that it only works for one line if all lines on the DSLAM are vectored.

This would mean that it shouldn't be a setting available to retail-level service providers. It ought to be a setting used only by the operator of the DSLAM.

It suggests to me that your DSLAM wasn't enabled.

The FEC and interleaving settings are having an impact on your bandwidth and latency; that "max attainable" figure would probably be around 110Mbps if you were on fastpath, and at least that if G.INP were enabled.

You mention "ISAM" - does that mean your DSLAM is made by Nokia/Lucent/Alcatel? If so, it would be strange to have another manufacturer having problems with G.INP!

Still, it's a good result for the attenuation. On a BT line, that attenuation would be somewhere around 300-350m, I reckon.

Vectoring would work just as well for a single line if all the other lines were vectoring friendly.

The plan I am on is 80/10.

Yes I believe Alcatel cabinets are in use, bcdm chipset reported by the Huawei. Regarding G.INP, yes apparently it has been causing line drops for some customers but there had been none on my line because of it and the pings were the best I had, throughput dropped 5 - 6 ish mbps when it was turned off. I *think* lines having problems with G.INP are using Fritz boxes/old Netgears and other makes, in some cases being swapped out with Technicolor devices which now seems to be the fttc owners standard device.

Here we don't have certain sync profiles based on disconnections etc, I can unplug my modem as much as I want and it will sync at the same speed, also we can request for interleaving to be switched off, is this something I should do? Presumably I need it if I am getting FEC errors. https://www.manxtelecom.com/personal/internet/broadband/online-gaming

What is the purpose of your broadband connection to the Internet?  :-\

The answer (or answers) to that basic question should allow certain aspects of the circuit's operational mode to be defined.
