What is your BB Line Attenuation?

hamster

Just curious - As question asks what is your BB Line Attenuation?

Let me start:

Eircom BB Waterford Rural location: 37/21 dB

towel401

10/8dB - i'm about 200 meters away from the Killavullen exchange

but I still have problems with my line - SNR goes through the floor most nights and approaches the danger zone, disconnects sometimes

AlmightyCushion

Mine are 36/22 dB. I'm with Eircom on the Sligo HPO exchange. I take it the lower this is the better. Is this true?

BloodSugarSex

24/13 dB - i live in drogheda and im on eircom, never had a problem with eircom bb, its very reliable

Figures in brackets have been shown to provide a stable service in practice.
* Attenuation - How much signal is lost on the line
(should be <56 dB downstream, 37 dB upstream)

Looking at wiki.

Interesting so far... a neighbour of mine has a fairly high value 50+ and was considered borderline.

Pacifico

51/31 unfortunately

Sucks really

Cheers hamster.

so which is better, higher or lower?

How much signal is lost on the line - I guess the lower the better. My connection in Dublin has a lower value than down in the country.

Anyone know of a definite borderline case where it cuts off and comes back on? I wonder when this value becomes critical.

ye are looking at the incomplete picture

on a netopia go to expert mode > diagnostics and line stats

post the FULL diagnostic in including the MARGIN

a margin under 10 is dodgy and under 8 is disconnect and crcville

there is no option in diagnostics for line stats, its just a test for connection problems

EDIT:

have it now

SN Margin (dB) 31.00 12.50
Line Attenuation (dB) 24.50 13.00

is this dodgy?

Sponge Bob

god no , thats great , massive margin.

now try the Dream On This Is Fukin Ireland Test and post that back

how do i find the noise margin?

Sponge Bob

you told us already , your margin is 31 and your attentuation is 24.5 , it only wants the 2 download values.

BloodSugarSex

sorry

We estimate that if using a rate adaptive up to 8Mbps service your maximum line speed will be: 8128Kbps

If you are on a Max product, that uses the IP Profile system (sometimes called BRAS Data Rate) if you maintain the above line speed for 3 days or more your IP Profile would be set to: 7.15Mbps

If your service provider uses ADSL2+ we estimate you may manage line speeds of: 19944Kbps
With ADSL2+ the maximum IP throughput is likely to be around: 17650Kbps

this any good?

Sponge Bob

Yes, 17.6mbits is good .

its a pity eircom doesnt have a 17mbit package

Sponge Bob

well ADSL2+ is about the best technology ever likely to be widely available.

The 5 big cities will get VDSL2+ sometime ....end of the decade maybe .

hamster

Nice to know I have some niggle room for better rates.... I really did think I was marginal going back.

BloodSugarSex

does ireland only have ADSL? we really need better broadband in this country, 230kb/s is not enough for me to download a file, im very impatient! the japanese have great a broadband service, around 17mbit/s

Sponge Bob

the Japanese have 100mbits , 17mbits is a bit slow and old fashioned for them

wow ive really fallen behind the times!

and these are symmetric lines, or at least have decent upload speeds


none of this piddly upload rates that are only just good enough to send ACK packets & your credit card details to some online rip off web service. no japanese/korean lines are actually good for something. apparently slovakia and a few other countries have good lines for cheap too.

How does this stack up to others out there am i lucky or unlucky??????????

20mbps on adsl2 is very good.

MickyJoe

S/N ratio (SNR) - the lower the worse - ratio of inherent noise on the line and level of DSL signal (or vice versa)

Attenuation - the higher the worse - loss of signal between exchange and your router (modem ..)

There has been posts around that give an idea how to interpret these figures.

Downstream Rate: 9214 K bps
Upstream Rate: 608 K bps
Downstream Margin: 7 db

I want.

After waiting for so many years I eventually got Eircom BB and am happy to post my fine attenuation of 9/4 dB.

Praetor

Sounds like fun!!

Downstream Rate 12284 kbps
Upstream Rate 1021 kbps
Attenuation 7 dB

Nothing to complain about!!

Sconsey

Is there anything I can do to improve line attenuation?

I am usually getting around 55 down, I bought a router a while back that is supposed to be good at handling weak signals and that has made a small improvement but based on my current stats I will never be able to have more than a 1mb line...

Sponge Bob

Thats it for you in a nutshell sconsey. You sound like you are about 3.3-3.5 Miles out from the exchange with a good line .

Digiweb wireless Metro

GG +13 (?)
SNR 38
PL 28

I have'nt a clue what that means except the installer let out a small scream of delight when he saw the numbers!
