Interleaving

lmck · 29-04-2003 03:37PM #1

Hi all

Louise McKeown, from Netsource here. The reason I am posting this afternoon is in relation to Interleaving. You will recall I made a post here two weeks ago stating interleaving was turned off on our RADSL product (SOHO), this information was posted by me after I received verbal and written confirmation from Eircom that this was the case. However on Thursday last it came to light that Eircom had mis-informed us, and that interleaving was in fact not turned off completely, but very much turned down (from 50ms to 19ms). This is because the reach and therefore the availability is greater when left on marginally.

In respect of the board rules, I do not want to go down the route of commercial information, however I do want to assure everyone the reason for making this posting is to keep you informed and to apologise for the incorrect information we passed along.

I understand a number of you ordered SOHO services from Netsource on the basis that Interleaving was turned off, so should you have any issues, questions please e-mail me directly (louise@netsource.ie).

Regards
Louise McKeown

Ya gotta love commercial interaction.

I heard fast track was turned on, is that true?

Pity about the interleaving, but thanks for the correction/update.

Hi Loiuse,

I (Adam Beecher) rang you last Thursday to enquire about your DSL products and you promised to call back after checking into my line. I haven't heard back from you since, even though I followed up myself on Friday. Could you follow through on your promise and call me back please? I'm sure the members of this forum would love to see commercial interaction working in both directions.

Thank you,
adam

Louise,

Top marks for coming back and updating us in such an open, friendily and honest way, long may it continue.

dahamsta · 29-04-2003 05:57PM

Louise has since been in touch, thank you Louise.

hmm, not to impressed with that. The main/only reason I went with netsource was on the basis that interleaving was off. I know its not their fault so what can ya do :rolleyes:

Praetorian · 29-04-2003 07:42PM

I was speaking to you about 3 weeks ago about RADSL availability in Balbriggan. You informed me that my exchange was scheduled to be upgraded in the next two weeks. I too was promised a call which I never received.

I called Eircom and they told me that my exchange might not be upgraded until December 2003 or later.

North County Dublin ?
There are approximately 20,000 people in Balbriggan. Skerries, Lusk and Rush have large populations aswell.

Interleaving ?
I would love to see a copy of this written letter from Eircom.

Damien (damien69@eircom.net)

Thanks for the heads up Louise, much appreciated.

I might be assuming a lot, but i expect that is what the interleaving will be on all RADSL products.

MadsL · 29-04-2003 11:37PM

I think credit is due to Netsource for attempting to get interleaving turned off, whilst there has clearly been some confusion, at least we are now in a situation where interleaving is on it's 'short' setting - a step forward at least.

Why it can't be turned off on a demand basis for each subscriber line (this is available in the US) or per Netsource's request at least on lines that are sold though a reseller is beyond my comprehension.

I have a million conspiracy theories (well two or three...) but the best response I have had to date from eircom is that it is 'technically impossible' or 'policy' not to turn off interleaving. I shall attempt to get some kind of response from them again once I am connected. I'll post here.

In the meantime fair dues to Louise.

melachi · 30-04-2003 12:12AM

Lucky that I saw this or else I would've switched between the same connections, €165 excl VAT for nothing

What shocks me though is that they turn interleaving down for a lower cost connection but I who's got €169 (excl vat..) a month 1mbit still has to deal with ridicolous ping times?
30-40 to UK would be acceptable. 80-90 isn't

RapierX · 30-04-2003 01:02AM

I'm unhappy too. I'll still get the service because any DSL is good DSL in this country. Gamers are ultimately looking for the lowest ping, in Germany Fastpath is sold to people wishing for a lower ping rather than a stable (interleaving on). I don't see why it could be so hard for it to be turned off.

ozt9vdujny3srf · 30-04-2003 04:31AM

Why is it that, when the line is tested, the customer can be told whether or not the line needs interleaving for it to work.

Is it possible for individual customers to be given a choice, or for people who are close enough to have interleaving switched off.

For a product I am already paying slightly more than the competition for this is something that is a drawback.

Is it technically possible, yes, absolutely. Have Eircom put in place the infrastructure to allow this, I assume not.

To be fair to netsource, this has nothing to do with them, the ability to turn on or off interleaving lies with Eircom. If Eircom don't want to make it available to their customers and ComReg don't force them to make it available, then I assume there is nothing netsource can do.

Yes, but remember you are also getting a fixed IP address and no Cap. In the UK you typically pay about an extra GBP£5 per month for a fixed IP, so EUR 10 isn't too bad and well worth the difference for no cap IMHO.

ozt9vdujny3srf · 30-04-2003 01:56PM

of course its eicoms fault, I am just wondering why they can't keep to their original promises.

The fact remains that a large factor in me ordering this service was beacuse I was told interleaving was off.

(p.s. i have had no real problems with netsource and I have found their staff to be very ehelpful in any query's I have had)

Nitrox · 30-04-2003 01:57PM

If line test is fine can anyone tell me why i should not go with Netsource right away?
It is cheap, no cap and i have not yet heard anything bad about them, so whats the catch??

CitySickness · 30-04-2003 02:00PM

Well, I'm holding off until I hear from somebody who's actually got the service up and running - and we know what sort of reliability, download speeds & pings to expect from Netsource.

If you're not a gamer then go for it.

I'm with CitySickness.
As far as I can tell, no-one here has actually gotten the service yet.
I don't want to sign up for something that no-one can actually vouch for.

My only worry is that since they have no cap, they may attract a lot of heavy users. This may be a problem on a 48:1 contention ratio.

None of this implies that I am in favour of caps.

melachi the interleaving is at a very low setting, so its fine for gaming, not as good as esat, but still better overall.

dahamsta · 30-04-2003 02:39PM

I'd sign up for it in a flash if I could. Whatever about the interleaving issue - if in fact it even is an issue - Netsource seems to offer the best feature set and appears to be willing to engage with customers*, which is more than you can say for all but one other ISP in Ireland, which isn't in the DSL business yet. Someone's got to be the first mover, and I think the reaction to this issue is a little unfair. At least Netsource had the guts to come here and tell us to our faces.

adam

*Ok, in my case it required a little sneakiness, but would Eircom or EsatBT have rung me back because of a post here?

Respectful, informed, polite.... could this *actually* be from a telco? My word... it appears it is.

Well, fair dinkum to Louise, thanks for the timely information. Long may you continue to peruse these boards.

I understand inerleaving causes lag & high ping for gamers but I dont know why or how so could someone explain it?

dahamsta · 30-04-2003 03:41PM

Results 2 and 3 from a Google search seem to explain it pretty well.

Cheers for the links whereas before I was blind now I've been hit by a tree

crazyasafox · 30-04-2003 08:07PM

I understand that the interleaving issue is down to eircom setting it at their exchanges but going by BK's link on interleaving
"http://www.dslreports.com/shownews/184" it also seems to point the finger at the make of modem.
Quote
"Some ADSL modems allow the user to turn off Interleaving, or turn it down to a narrow range, at the expense of possible data-loss on noisy lines. The Cisco 675, for example, has a full operating system inside it, and one of the attributes of the ether interface is Interleaving. See Randy Lutton's US West page). Some ISPs may be delivering this unit with Interleaving on, and some off. In other cases, it is the DSLAM (central office equipment) that has the Interleaving set, and this cannot be changed."

As the quote says you can not change the settings of your exchange but if your modem is doing interleaving also as default surely this is only adding to it.

melachi · 30-04-2003 08:38PM

Wrong

MadsL · 30-04-2003 11:15PM

Malachi grunted...

Wrong

Err...kinda...my understanding is that interleaving is set on the line as short, long or off, but some modems can configure the DSLAM from the consumer end if the DSLAM is set up this way. Eircom DSLAMS are not setup for this.

I was talking to an Esat engineer the other day who informed me that eircom are using about 5% of the functionality that they could be using both on the DSLAMS and the ATM side of things.

Individual subscriber lines could be configured, even by the consumer themselves (given say a Cisco 675 as quoted above) if eircom were prepared to......

err......(take your pick here because I don't think we will ever know short of getting an independant engineer to take a look -FOI anyone?)

...if eircom were prepared to......

1. make some further investment upgrading old linecards/firmware
2. roll out both ADSL and RADSL and offer advice and choice to the consumer about DSL 'flavours' (LOL - I kill myself...)
3. bite the bullet on distance from exchange and invest in alternatives (how's that wireless access coming eircom?)

Then we would have choice about the most suitable xDSL package for our needs, along with choice about the delivery system - fixed speed ADSL for urban, variable RADSL for distance and wireless for buttf##k of nowhere..

Instead we have a one-size-fits all, ain't you lucky to get it attitude...and don't ask us for anything different because you ain't gonna get it...

If you read the extra posts at the bottom of the article I posted, you will see that the modem gets the interleaving settings from the DSLAM, therefore you can't do anything about it. This makes sense, the modem has to be able to deal with the interleaved packets that it receives. So it really is all up to Eircom.
