Lex upgrades

[JacK]

Hi !

I have been told that most centrals cannot support 4 or 8 Mbps but only 3.3.

Is there any listing about the supported bandwidth by each central ?

Is there any roadmap about upgrading the centrals ?

Are there people with a 8 or 4 Mbps subscription with an effective bandwith larger than 3000 kbps ?

TIA for feedback,

JacK

Jack,

most centrals can support up to 8Mbit. But, ... for the moment there is only 1 network provider that supports 8Mbit connections, which is Scarlet (and it's partners, adsl2fit, xs4all,la tribu ...)
But, since Scarlet is having nationwide network troubles concerning downstream speed it's *normal* that you won't see anyone having more than 3000kbps (or 1000 kpbs for that matter).

Before the problems I have seen many people having more than 4000kbps though, so I think: yes, many centrals support 4-8Mbit connections, but only the BROBA2 or BRUO ones....

Probably all DSLAM's support 8Mbit/s , but not all carriers offer it and/or not all clients live close enough to support 8Mbit/s .

For the moment only Scarlet offers 8Mbit/s profiles on their DSLAM's (= BRUO-connections). But because scarlet covers only a small part of belgium most people won't be able to have 8Mbit/s because they are on a Belgacom DSLAM which only support profiles up to 4Mbit/s down and 512kbit/s up.

Btw, scarlet 8Mbit/s A2F connections don't seem to be affected by the scarlet problems.

Most 8Mbit/s users get speeds around 700kbyte/s down.

Hi,

Tnx, let's say an ISP offering 4 mbps on KPN network - Liège.

I never heard anybody from this ISP till now with a bandwidth larger than 2800 kbps nowhere in the country.

I think all ISP have a connection from Vilvoorde InterXion colocate and it was upgraded on Sep 17 th without any improvement.

Are you sure that all lex in Wallony support 4 Mbps ?

The ISP says there are only a few and most only support 3.3.

TIA,

Jack, every DSLAM will support up to 8Mbit. But the owner (most of the time it is Belgacom) won't allow anything higher than 3.3Mbit. In some cases Scarlet has an own DSLAM and they provide up to 8Mbit. So if there is a Scarlet DSLAM you can get up to 8Mbit. If not, you have to stick to 3.3Mbit.

Hello,

Tnx for explanations. Do you know whether KPN intend to implement its own DSLAMs everywhere in a near future ?

Best rgds,

JacK

[Sensei Zeon]

no one really knows it, but i don't think they are going to implement more DSLAMs, because the prices of bgc are outrageous

[The Oddity]

For the record:

Their are very few LEX'es who amre ready for 8Mbit/s services.
All the BGC LEX'es can provide 8Mbit/s if their is a DSLAM (BRUO-II) present which is configured for 8Mbps.

Now, Belgacom doesn't have 8Mbits profiles on DSLAM for private people.. only for some test-environments and maybe some corporate environments.

Scarlet has like - i thought it was - bruo-ii dslams in about 60LEX'es. And they are not planinng to extend that network. Simply because Belgacom is charging a lot to place BURO material from OLO's in their LEX'es.
So 8Mbps coverage is very small and will probably remain very limited, untill Belgacom would decide to maintain a new policy concerning 8Mbps profiles on their dslams. (BGC has much more coverage).

Tnx for info.
Is there a listing about wich LEXs are available for 8 Mbps ?

TIA

[Sensei Zeon]

I'm afraid that such a list doesn't exists (anyway not for everyone to read)

if some finds it, pls keep us informed, so we can put the list in public (if allowed)

[The Oddity]

Jack,

As sensei zeon said.. that information.. isn't that public .
The only way to find out if the LEX your are hooked up to is ready to provide 8Mbps adsl, is to check at the site of an ISP which provides such subscriptions if they can provide you such a line...

Why wanna know all LEX'es? You only need the LEX the closest to you.

Hi The Oddity,

In fact, I only have to know whether my central can support 4 Mbps.

My provider advertises it, my synchro is at 4096 which does not mean my LEX is able to support it. I have no way to know and my provider says I cannot get 4 Mbps becasue I am 3.5 km far from the central.

I reckon it's untrue : or tle lex is a KPN and supports 8 Mbps and of course I should have 4 Mbps or not it's not. I would like to know.

Best regards,

JacK

[The Oddity]

Jack,

If your synchro is 4096 and you do not have any difficulties synchronizing, or problems concering synchronisation drops, then your are withing radius of 4Mbps synch and your LEX supports 4Mbps. Actually it's not the LEX, but the Scarlet (=former KPN) dslam which is configured for 4Mbps.

So if your synch is OK, then their isn't any problem concering LEX, DSLAM, Synch or whatever.

Why do you say: "4096 which does not mean my LEX is able to support it" ??

Do you think you are on a bad line or something because the speedtest isn't always 4096 or isn't downloading at max speed? That's because:
1. there are problems on the Scarlet network
2. In belgium on adsl there is a lot of overhead, which means, with perfect 4096 synch you'll get only like 3600 maybe little more.. but not 4096..just because of overhead.

Your post is confusing.

Nite,

Because my provider claims I never shall have 4 MBps because I am 3.5 km far from the LEX, I thought that BCG limited bandwith to 3.3 MBps.

When I was on Turboline I always was > 2800 KBps 24/7. I am now for more than 3 months on KPN (Belcenter) with an unstable bandwith variing continuously between 1000 and 2500 kbps, often less and I don't catch why. I was thinking I should obtain 3550 Kbps.

My line is good :
STP ISDN PPP always ON
Used line rate 4508
Fast used Atm rate 4096
Noise Margin 15 dB
Line attenuation 29 dB
Output Power 19 dBm

Tnx for your concern,

JacK

[Ex0dus]

I know what Jack is trying to say,

I have the same problem (it isn't a problem actually)
I synch @ 4096kbps, but I optain the same actual bandwith as my sister next door with a 3.3Mbps line

so I don't get teh actual bandwith of 3600kbps
I think it's bcoz i'm on a LEX which doesn't support 4mbps, only 3.3Mbps BGC stuff

Let me explain again:

If you are able to synch at 4096, the LEX you are connected to has a DSLAM inside the building where your line is connected with. This DSLAM belongs to and is maintained by Scarlet (=Former KPN). So they decide which speed to configure, where users can synchronize with (=4096).

If the DSLAM is a DSLAM from BGC, then you will synch at 3360 because BGC has set so on their DSLAMS. The LEX doesn't involve your speed..that building is owned by BGC, but Scarlet has material in it.

As you are both synchronized at 4096 it means that you are not too far from the LEX/DSLAM or that your DSLAM supports 4Mbps.
Again: this has nothing to do, with whether the LEX supports it or not.. as you say: you synch at 4096 it means that it's supported.. if you would have synchronization problems.. then it would mean.. you are to far from the LEX/DSLAM to synchronize at max. synchspeed.

Now, in my opnion, you guys are suffering from the Scarlet network problems... and that's the only thing. Further of all.. you have also a lot of overhead.. and the network of Scarlet is less than the BGC network..

I don't know who says you are to far.. but that's untrue.. if yoy synch without problems at that speed: you are not too far.... the low speed you have.. concerns the Network Problems at Scarlet according to me.

I would say, have 2 weeks of patience.. a solution should have been found by then.

Hi The Oddity,

Tnx for your explanations.

Let's say I have patience for over than 3 months... and no improvement till now : the band width for instance is about 1500 kbps just now and 2 hours ago about 900 kbps (test done with a 17 MB zip file from their own server). I fear the given quota by KPN for my LEX are too short and my ISP tells me KPN refuses to upgrade as long as the band width does not drop under 800 kbps !
It's far from what 's advertised on their portal even if I know there is no warranty nowhere about the band width.
I always had a stable band width with Turboline (> 2800 kbps) and never reach it with KPN from day one.

Cheers,

JacK

[The Oddity]

Jack,

First of all: 2800 does not equal: 3360 --> overhead
Scarlet has also overhead, which means you don't get the ful 4096, but now you cannot test this serious because their is a national dowstream problem on the Scarlet network. Read the topic i mentioned. This has nothing to do with quota to your LEX...it's NATIONAL!

Have patience untill national problem is resolved, this is already from beginning of september...

btw: it's not necessary to quote me everytime..

Hi

I known : I was expecting about 3550 kbps. Even before : I never obtained a satisfactory band width from the very beginning : max 2600 and really seldom and unstable which corresponds to a 3.3 Mbps and no a 4 Mbps connection. If the band width is unstable, that tends to proof that the ISP does not rent enough band, isn't it ?

I'll just wait and pray thus
Best rgds,

JacK

[Sub Zero]

No your statement is not correct. Scarlet, the owner of the DSLAM's has a problem with bandwidth, but it is Scarlet's own bandwidth that is the cause of this problems. But it is not that they have not rented enough bandwidth or something like that. Just be patient... It will all work out.

Cheers
