Interleaving Profile

DECEiFER

This isn't my first time creating a topic of this sort. But, here's the lowdown on the latest goings on...

I just rang my ISP, UTV, and asked them to change my Interleaving Profile down to the lowest possible. Apparently, I'm already on the lowest for my package (3Mb). Though, while it's the lowest, it's still higher than it was pre-July 2008, before the speed upgrades.

This is the current state of things, on the "lowest profile":

Approximate round trip times in milli-seconds:

I checked in the BT Voyager 210 router. Note that before the upgrades, the Interleaving Depth was set at 1/1, as found in the line stats. It when went to 64/8 after July 2008, and it was since lowered to 32/8. Still, it's a lot higher than 1/1, where boards.ie could be pinged at 15-20ms, in-line with current fixed line broadband trends, so to speak.

I was told that it cannot be lowered by UTV, as it's at the lowest possible, apparently. Does anyone have any experience with getting theirs lowered back to before the upgrades? If so, I'd be grateful to know how you went about getting it done. It's a load of bollocks the 3Mb package before the upgrades could manage it, but since then, cannot!

The only thing that I can think of is calling to the exchange, which is 100m down the road from me, and asking an engineer. Hell, I don't even know if that will work!


So, how 'bout it? Any suggestions?

UTV are right, you can request to be put on the lowest interleaving profile but not turned off (this can only be done by Eircom, last August when all the upgrades happened, they turned Interleaving on for all customers). If you were an Eircom customer, you could quite possibly get it done.

It was always on, but at 1/1, it might as well have been turn off. So, aside from switching to Eircom, there's no way to get it back to 1/1 or off completely by asking, begging, UTV to put a custom request onto Eircom? How about my idea of calling to the exchange during the late morning, or whatever time during business hours, and asking an engineer for a favor?

Before the upgrades, it was off yes (as I implied) - then Eircom turned in on all DSL Lines and you now have the option of high or low interleaving (easily changed by UTV) but with regards to getting it turned off, I reckon asking an Engineer would probably be best (purely because calling them when your with UTV won't get you anywhere, jasus even asking UTV to do it probably won't work).

Weird, because any router I had used prior to the upgrades did say it was on, but at the minimal setting. Perhaps the routers were wrong.

Can an engineer do it from the local exchange or would he/she have to escalate it?

cpu-dude

Perhaps that reading means it is on but at it's lowest possible (1 to 1 being off).

I wouldn't know but it's sure worth a shot, I've heard stranger things happen.

Eircom aren't allowed to do this if UTV or other operators can't do it.

Eircom retail has access to only the same settings that UTV have.

Or at least they are supposed to, if they have more access, then this should be reported to Comreg as it is unfair competition.

1/1 is the exact same thing as off, just another way of expressing it, where Interleaving is concerned? Ah ya something new every day!

Thanks for all the replies.

Can I ask that anyone on Eircom who might have had their Interleaving turned off or put down to where it was at last year before the upgrades, to post and let us all know? If we get people, then we can report the issue to ComReg, for whatever it's worth to them.

Eircom turned on Interleaving to cope with the upgrades, more bandwidth for everyone means more congestion on the network - the interleaving increases pings but gives greater bandwidth at the same time which helps the network cope with these increases speeds, going to ComReg about it won't do a thing.

Now, what might be worthwhile is going onto Eircoms Gaming profile (7MB Down with no interleaving and 384K Up with high interleaving) through UTV - thats a lot more likely than Eircom turning if all together, the Wholesale Access most likely won't give any options to do so. If all else fails, move over to Eircom.

Thanks man, I'll consider all that.

Although, I'd still like to hear about anyone with Eircom who has had their Interleaving turned off.

No problem. Everyone did, every person connected to an Eircom exchange had Interleaving turned on.

No, what I meant was after the upgrades, by request.

I Had no interleving before the upgrades then when the upgrades came my pings went from 10ms to 60ms overnight. Ive since asked eircom to lower my pings and they now have me back on low pings which are 6-10ms to Irish servers and 15+ms to uk servers.

That would be the low interleaving, but it's not off. Everyone defaults to high interleaving.

According to my router I am on:

/proc # adsl info
Current Training Status : Showtime
Current trained adsl mode : G.Dmt
Current trained adsl path : Interleaved
Downstream Bit Rate : 7616000 bps
Downstream Noise Margin : 15.0 dB
Downstream Attenuation : 8.0 dB
Upstream Bit Rate : 672000 bps
Upstream Noise Margin : 12 dB
Upstream Attenuation : 15.5 dB

So I should be able to get this reduced?

I've ****ty pings at the moment but I don't think this is to do with interleaving. During the day I get 30ms no probs.

Yes, just ring up and request to get your profile dropped to it's lowest interleaving.

For some reason, several modems I've seen report 1/1 interleaving as "interleaved" under the "interleaving" etc. section. The ping times would be excellent.

Also, I know of a couple of 3 mbps customers, one with BT one with eircom, who were upgraded from 2 mbps but they didn't have a jump in ping times? I'm not so sure that all upgraded lines were set to 64/8 interleaving. From what I remember of threads here, I only saw complaints from users who were upgraded to up to 7.6 mbps.

I think the best thing to do is to nag UTV until someone listens to you and applies to eircom wholesale for interleaving set to minimum. Perhaps getting them to reset your profile to 3 mbps would revert the interleaving to default? I expect from what I've seen that default is better than 32/8.

Finally, I'd check your line stats before pushing for a reduction in interleaving. It's there for a reason. If you've a <8 dB signal margin average after checking it a handful of times, I'd advise to downgrade to 1 mbps to get good ping times.

Not quite. No interleaving is fast path, it would show up on a Netopia modem as Fast rather than interleaved. 1/1 is just very low interleaving.

The DSL line in work (where I am right now) is on fastpath, here's a ping from it:

I think the people who were set to 64/8 were former 7.6 subscribers who downgraded - their speed was changed but not the interleaving depth.

My line stats are as good as they possibly can be, for I am only 100m from the exchange. My Line Attenuation on both sides is only and consistently 2dB, with decent SN Margins much higher than 8dB.

I'm also on 3Mb. However, I did downgrade from 7.6Mb last year sometime. I'm going back to 7.6Mb effective from the October month start.

Ah well, I'll just have to keep nagging.
