BT & Interleaving

Bt have put interleaving on my line even though for months it had been rock steady , my pings have shot up , my customer support asked BT to turn it off and BT told them it had been,as you can see below its still on and my Customer Support are arguing with them but they are insisting its off.
Has anyone any idea how i can get round this other than drop back to a 2Mb connection where interleaving will not be a problem?

Send the proof to your ISP and tell them you wish it removed or you will move to another ISP that will allow you to have it removed.

Another aspect is interleaving. This is a technique that allows some of noise to be tolerated more easily. It is combined with forward error correction (FEC). An interleaved line cannot achieve quite the same level of max sync speed as a non interleaved line (presumably because of the overhead of the FEC). Interleaving does increase the latency on the line (the time for packets to be sent/received). There are different levels of interleaving and correction which can be used, but BT only use two settings, on and off. Non interleaved mode is called fast mode.

Some ISPs have control over interleaving themselves and can turn it off or on.

I have sent them the screen shot and assume they have sent it to BT.
My isp is dealing with BT and trying to get them to turn it off but BT are saying they have already turned it off ,how will telling them i will leave help?

BT have admitted that sometimes interleaving is turned when not required on some lines, if BT find such lines they will switch it off.

With interleaving their are three options:

auto - the dlm process decides whether it is required to correct errors
on - always on
off - always off

Your isP should be able to request it to be switched off, it is not upto your isp. They should do as their customers request.

hope that helps

I have already said i asked my isp to ask BT to turn it off, my isp did this and BT said it would be done, they didn't turn it off so my isp phoned again and BT said they had turned it off.
The problem now is my isp are fighting with BT and saying to BT its NOT off and BT are saying it IS off.
I am stuck in the middle with a crap ping and no gaming :mad:

Are you sure the router is reporting it correctly.. and it didnt always show that?

My router shows INTERLEAVING 1 for no interleave on the line and INTERLEAVING 16 when its switched on.. so might be that ALL lines have it on but its not got a value / point to interleave at.. ?
Just guesses.. but maybe if they say its not on.. it could be your router reporting in a funny way.

If you know it has shown "OFF" in the past then ignore me

The ISP could ask for a MSR reset which would do the job.

If the MSR was reset and interleaving was still on the line wouldn't i end up with the same result?

My MSR was never a problem and my connection was rock solid, for some reason BT decided to turn it on and now will not or cannot turn it off. :mad:

Good point mate , as i never had any problems and my ping was always in from 30ms i never had reason to check.

Approximately 2 weeks ago i suddenly couldn't get a ping lower than 50ms and posts started to appear in the IDNet forums saying people were getting high pings and big lag spikes.

I assumed the router was reporting it correctly and it would explain why my ping was higher.

If BT insist its off what could be causing this?

The only router I know how to tell interleaving on is the USR 9105 throu 9108... but I would suggest finding another bit of equipment (BT Voyager 105 etc.?) where you can get a second opinion on the interleaving value or if its on the line..

If you can get into the status screen of a Voyager 105 (ctrl or alt+f1 or something in the "Status" window) I can tell you what should be shown for a non interleaved line.

A MSR reset will train the line again and unless in the training process the first time it was turned on then it wouldn't be enabled on another retrain.
 
I dont know anyone with a voyager router .

My pings are slightly less tody but still a lot higher than they were.

Its interesting that your pings are FAR higher.

Possibly exchange contention? Possible problems at isp? Possibly CPU load problems on your router? My pings were much higher when I had QoS turned on on the USR routers.. cpu use goes through the roof on the tiny devices.

Thanks mate ,

I'm know nothing about how this all works as you can probably tell so bear with me.

If I'm reading it right you are saying the reset would knock interleaving off if it was on?

Is this correct?
 
Wow :(

I have tried a usb modem to rule out it being a problem with my router and the results were the same. :(

I am now in a bit of a dilemma as if my isp cannot sort this out do i take a chance and move to another isp on max and hope things go back to normal or go for the safe bet and drop back to a 2mb package where interleaving couldn't cause any problems.
 
If you use bt_test_user@startup_domain as the login does www.bt.net return pings? If so you can check if its BT and not your ISP.

I cannot get it to connect do i need a password?

I can get onto the BT speedtest using speedtest@speedtest_domain but the one you suggested doesn't work.
