Line Attenuation help?

antocann

bit of help please ,

got landline fitted so i could get fast(ish) broadband

heres my line details


eircom say i can only recieve up to 2 mb broadband

first they tried to tel me i was to far away from exchange , (its outside my front door )
then they said cant get 7mb in my area , parents are a few doors down from me and they have it a year


speed test gives me this :



so basicy my query is , after gething new line fitted as i wanted faster broadband why cant i get it

to be honest i would probaby get faster internet from my toaster

Have a read of the above - it does seem as if you are living virtually in the exchange.

Do you know what products are available from your exchange.

Also is there any problem with any aspect of your internal wiring?

If you ask the reps in the Eircom forum they should be able to investigate further I am sure.

antocann

thanks for your reply

yeh the exchange is right outside my front door litterely lol
and my line was wired strait from it to the side of my house .

the guy that wired it stated that i would get high speeds as im so close to it and new line fitted ect.....

i have opend a thread in the eircom section and still waiting on a reply.
thaught i would ask some people in this section as i was gething no where with them on the fone today

Don't suppose you have Sky multiroom do you??

Otherwise eircom have the line in test mode which throttles it.

antocann

nope , no sky ect

Dodd

It will also depend on your modem too.

Are you still using the old modem.
Analog=old and will still be slow no mater connection you have.

antocann

new modem only recieved it off eircom , new line ect

when i rang eircom al they kept telling me was that there was no next gen broadband in my area ect .....

i tried telling them i jus wanted the standerd bb but they were having none of it saying this that and the other

Dodd

Do you have a limit of usage as in 30 gig per month and went over it.?
I am just saying as it happened me a good while ago.
You should be able to check this on their site and check your traffic.

antocann

yeh i have a llimit but i only have broad band a day now

lucernarian

Complain to eircom about this madness. That line can handle any speed available in the DSL specs. And start a thread in the talk to: eircom forum here - http://www.boards.ie/vbulletin/forumdisplay.php?f=1293

By the way, at least you can get 2 megs! The family have a 1 meg line on a line that can handle 2 or 3 meg but eircom have decided on our behalf that it can't handle higher speeds.

On that point - the signal margin is so good there couldn't be a problem with the wiring. And there is so much signal margin it's quite possible that the OP can plug his modem into the wrong end of a filter and still receive 2 mbps!

thanks for your reply ,
i have tony from talk to eircom looking into it ,
yeh my parents have a worse line than me but yet they can get the full 7mb and max my line will get is 2mb

Analogue has nothing to do with it, and neither will the modem unless it's broken.

antocann

so kinda an update idunno lol

have being pm'ing tony from eircom , and 1 thing he said to me wich is kinda funny

the exchange is outside my front door and he said and i quote
"I can see your position as at least 1kM from exchange and speed capacity of line approx 2Mb"

this is what annoys me , im about 3 or 4 feet from the exchange and my line is ony a couple of metres long

lucernarian

That's complete bull****. How can tony explain an attenuation of 2dB?! That means the line is less than 200 metres long in total They're pulling the same stunt on another guy here: http://www.boards.ie/vbulletin/showthread.php?t=2056229693

antocann

iv been keeping an eye on that thread , and it seems to be that there feeding every one the same crap ,

ill get a foto of my line and how the the exchange thing is from my house

antocann

ok so basicy heres a foto i took

lucernarian

That's just the manhole cover sure! Is the exchange across the road?

antocann

nope , i taught that aswell ,

but the guy from eircom that installed the line stated that was the exchange

lucernarian

Ah now, he must know where the exchange itself is located. Maybe there was a mixup? Or else he was condescending you. If it's a village, then it looks like a small redbrick shed or else made out of corrugated steel coated in green plastic.

antocann

ah ffs , so he lied to me ,

this is the ony shed thing i coud find on google maps

according to google maps 400 metres from me ,

timefora_J

Here is my 2 cents, I work for a UK ISP and the way we usual adjust speed is to adjust the SNR profile. All our customers are on a upto product which means you can get any speed upto 24mb depending on line length, quality, etc.

I don't know how eircom work their speeds but with the ISP I work for and with that line attenuation you would be very close to getting 24mb if you were on a upto 24mb product.

My guess is either their equipment in the exchange aint capable of it or they are just capping your sync speed at 2mb.


P.S Why now ask eircom what your line length is ?

Nitro Snail

Hey - when you run speed test -> run it once in the morning - evening and night. and compare the results. Its quite possible for slower speeds at different times of the day. Also contention ratio matters.

lucernarian

This isn't about contention and speed tests. The problem is with the raw data rate that the DSL connection is working on.

antocann

update ,

mark from eircom , has so far gotten me up to 3mb in speeds , and its almost reaching the 3mb running a speed test

lucernarian

I found out the location of the exchange in Strokestown. The coordinates I had on file are not completely accurate. It's a redbrick shed with a flat roof off Elphin st. near the forge hill estate on google maps. It's not accessible from Streetview. Hope that helps.

Can Mark explain why the line cannot take 7 mbps when you are within 1 km of the exchange? 2 dB attenuation is ridiculous, your line could take 24 mbps!

my house is located on the entrance to forge hill

antocann

could you link the location of it to my on google maps ?

lucernarian

I'm not sure how to get the pinpoint linked but here goes:

http://maps.google.ie/?ie=UTF8&ll=53.780823,-8.102959&spn=0.001132,0.002411&t=h&z=19

The building with the silvery square roof in the centre of that map is the exchange.

antocann

thanks , my house is one the the house that on the turn into forge hill so im not far from the exchange atall

lucernarian

2 dB attenuation would suggest you could feasibly get on your roof and throw stones at the exchange building, this is why I cannot get over eircom saying that your line can't handle more. How can they say this?!

antocann

there a pic i made , shows my house , parent house and exchange i think lol

lucernarian

If you drag the streetview "man" to where the p in "parent's house" is then you may see a glimpse of the exchange. It's a typical exchange for villages across ireland.

antocann

here it is on google maps street view

antocann

just when i taught they finaly sorted it out , i get an email saying upgraded ect ....
go any check my stats and iv bein upgraded to wat look like 3 and a half mb instead of the 7 mb package

lucernarian

Go ahead there and give us the stats for curiousity! 3 and a half sounds a strange one.

antocann

from router
Speed: 3776 kbps /384 kbps


and every time i run a speed test it dont go over 3.10 mb

lucernarian

Speed isn't enough, sure you already said what speed you were getting:)

Could you post the attenuation and signal margin stats for us?

antocann

theve changed it again now , and said its syncing at 7mb , cant see it myself to be honest

lucernarian

Those line stats are utterly different from the first stats you posted! Is that on a different line?!

Something's really not right here. Could you restart the modem and tell us if the statistics have changed??

Also, could disconnect any filters that are plugged into the same socket as the modem and make sure the modem is connected directly to the socket with just the standard 6ft cable?

Finally, can you confirm with eircom that you are indeed connected to the Strokestown exchange?

antocann

nope im on the same line , since theve been upping the speed they have realy change

iv already tried with out filters ect , no change .

router speed says im on 4 mb , wich eircom are sayin im on 7

Sponge Bob

Borrow a modem off someone else and see what it does. The exchange location is correct!

thefinalstage

Port issue?

antocann

i have 2 modems here , have me ma's one aswell
and no difference

Solair

That seems very odd indeed.

Try these steps:

Remove all the internal wiring from the line if you can. If it's a new-build house, you should be able to do this by just removing the faceplate from the eircom socket and plugging your modem and a splitter into the socket behind the plate.

If it's older, just open the first socket and remove the wiring that is going to extension sockets.

These days, people use DECT cordless phones for pretty much everything so it's really not necessary to have umpteen phone sockets.

If you have a Sky Box or anything like that e.g. fax, etc make sure that it is connected via a DSL filter. Every device on the line other than the DSL modem should be behind a filter.

Assuming all that is OK.

Plug in a wired phone (not a cordless). Press any key on the phone to silence the dial tone. Listen very carefully and see if you can hear a crackle or a 50Hz (low frequency) buzz on the line.

If you do, ring 1901 and tell them that you keep getting an intermittent crackle on the line and that it is making it hard to hear callers. Stick to your guns until they sort the line out.

It sounds to me like you've either got

a) an internal wiring problem causing line noise
or
b) there's some kind of a problem at a junction box or connection point outside which is causing interference.

Either way, you'll have to sort it out to get a decent speed.

checked line wen it was installed all was grand , only installed about 2 weeks ago , new wire ect ......

but looking at my router settings ,
shoudnt it say on that , 7xxxkbs or sumthing if i am on a 7mb speed

antocann

oh forgot to put , after being told that its syncing at 7mb
it changes again to this

lucernarian

Thanks for that second set of stats, it answered a couple more questions which I was about to ask:)

Apparently your line is running as fast as it can handle. Attenuation on a line is not supposed to change, that's why I'm confused. Your line has basically become 4 kilometres longer since you started this thread! The modem is reporting that the line is over 4km long, and your line speed of a bit over 4 megs would support that...

I have no suggestions for what you can do other than ruling out any internal wiring problems beyond any doubt, and to find a linesman when they're outside your house again. Streetview suggests they often park outside there. Tell them eircom has limited your line to 4 mbps because your line is apparently too long(even if it's not strictly true). Of course, they'll point out the exchange from your front door and then you can ask nicely or offer them a few quid or show them the router stats and then maybe they'll have a look at something in the exchange or any joins in the cable from your house to it.

As you're still getting a moderately fast eircom connection and those stats suggest nothing wrong (except that there is a hidden 4 km of wire in the footpath outside your house!) you may struggle to get eircom tech support to do something. Linesmen are friendly enough and it shouldn't be hard to get one being where you are:D Try that first at least.

Btw there's no interference problem, the only issue (and a pretty big issue at that) is the apparent length of the line or else a mistake with wiring in the exchange or an issue with the DSLAM's line card power output limits being set wrong or something unusual like that.

antocann

thanks for all your help ,
im prob best to leave it now ,

thanks for your help , you made me keep pushing them to get this far , from a line that i was told no way on earth could handle more than 2mb

shall i drop them an email queryying about how close to the exchange i am and the 4km line ?

also any idea why my stats changed since my speed was increased?

Sponge Bob

Have you tried without filter, ie plugging modem straight into phone socket?

The filter is what makes the phone work, not the modem.
