Thanks but that's for Windows and we've got Macs, so I'm afraid it won't work here. Never mind. If an interleaving on/off button is going to appear in Connection Settings in a day or few that will be very useful.

I'm pretty sure it isn't switched on as I've not reported any problems via the BB fault finder or ticket (having noticed that speed anomolies only seem to occur when the phone line is crackly).

RE: The impact of Interleaving

I am one of those who raised a ticket about the disconnections and what seemed to be down time around 10.00pm on average twice a week for the last few months.

As it stands interleaving is being turned on for me :?. I have read a few threads on the forum that claim this is detrimental to online gaming. As I play most nights I am a little concerned as I used to have a decent ping under 23, but lately it has been around 35.

According to your estimates and what others have said my ping will go above 60, which is likely to be unplayable at a decent level.

Will this new feature in the portal be like a "switch" you can turn it on and off? or will it be restricted?

I am happy to test out interleaving as long as I am not forced to live with any negative impact it may bring.

Is there a way of checking whether interleaving is switched on?

It may be a case that people who are not gamers may prefer to have it on if it means better stability of their connection.

There will be a button you can hit to turn interleaving off. You will also be able to see if it is on or not.

It'll be under connection settings.

James,

How about users who in the past ( such as err, me?) have requested interleaving to be completely turned off on the account and then are experiencing problems on the line ( due to the actual physical line ).

Will interleaving still remain turned off unless I myself initiate the proceedings to turn it on again?
Basically once BT fix my line ( tomorrow now apparently ) I just want to sync at my norm and try and get my line back into some sort of shape.

Regards,
James

If you raise an intermittent sync fault, it will be turned on.

You can turn it off after 3 days, but are advised against it.

Will there be an 'on' button as well and an 'off' button? Perhaps even an 'auto' button?

Cool! A portal switch for interleaving. Cheesy Looking forward to trying this out, and see if my game improves any when I set it "off"!

Thx.

When can we expect to see this function in the "connection settings area"?

An increase in latency means that ping times could rise, from 8ms to as much as 16ms.



PING plus.net (212.159.8.137) 56(84) bytes of data.
64 bytes from 212.159.8.137: icmp_seq=1 ttl=249 time=53.8 ms

64 bytes from 212.159.8.137: icmp_seq=4 ttl=249 time=54.1 ms

--- plus.net ping statistics ---
4 packets transmitted, 4 received, 0% packet loss, time 3001ms
rtt min/avg/max/mdev = 53.869/55.414/58.047/1.688 ms


If only my pings were 16ms. Latency in the order of 60ms actually makes the web slooow because modern pages have hundreds of small media items; it takes longer to request them than it does to receive the data, and this is amplified by each item being fetched one after the other.

I for one will be trying disabling interleaving, and if I have a stable connection for a month then any further problems will be BT's problem. I think this is being encouraged by BT so they don't have to fix dodgy phone lines who's faults have previously been regarded as acceptable.

Something some customers had been stating would be needed from the start of MaxDSL. We were told something like "the BT trials of MaxDSL were exhaustive and Interleaving would be a last resort".

As such we will implement the following procedure from tomorrow (August 1st):

- All new customers will have interleaving applied as “ON” by default
- All existing customer will have no changes made to their interleaving profile. Interleaving will only be applied if an intermittent synchronisation fault is raised and this will be done as a primary measure to resolve the fault.

the above statement is total and utter rubbish

I have been happily connected with no problems since upgrading at the start of July steady download speed of about 2779 to 2805 .
That was until 28/07/06 when interleaving was applied to my line without any consultation.see router logs below..

The increase in latency of between 8 and 16ms when interleaving is turned on is incorrect (Regardless of what BT have stated which is what James has posted). You will get an increase of between 20 and 40ms and in some cases more.

Mine went from 16 -> 20ms to 55 -> 60ms when I was upgraded to max with interleaving on, and many others have posted similar increases in latency.

Please bare that in mind if you decide to turn it on.
