Broadband over 1.5 km from VDSL cabinet

galljga1

Folks,

I am wondering if any one is availing of FTTC broadband more than 1.5 km from cabinet to which you are connected. If you are greater than 1.5 km from cabinet, please quote distance and speed of service if known.

Thanks all.

I'm 1.3 km, based on road distance, and considering the copper path and distance is probably a lot longer.

I'm getting 15Mb down, .900 up.

Cheers Captain,
I am in a rural area in almost a straight line from the cabinet (by road) with one right angled turn a couple of hundred meters from the house. I would expect the actual distance to be the same as the road or slightly less if they cut the corner. How do you reckon your distance to cabinet is more than the road distance? How did you get them to provide the service to you? In our area, they simply refuse to entertain anyone more than 1.2 k from cabinet.
Regards

are u sure you are connected to that cabinet? Sometimes people are connected to other cabinets etc for operational reasons

I spoke to an engineer who was working on the cabinets at the time. He was able to check it out and point out the actual cabinet.

1. Cables can take really strange routes.

2. Its not based on a distance rule, its based on tests which measure signal attenuation on the loop. If nobody outside 1200m qualifies the cabling either takes a strange path or the quality is poor causing the tests to fail.

I've seen landlines that run an extra 4km because they were fitted decades before the current road network. Sometimes you have to think back to TE/P&T days to work out what's actually going on.

Hi Folks
Thanks for the responses. I am dropping this now. Just very disappointed in the way Eircom sold this to me. I rejoined Eircom after being told that efibre would be available to me in March 2014. It was eventually available in my area in October/November 2014 but looks like I will never get it with current technology.
@d off with Eircom.

What are the figures used to determine if they make it available or not? ..... just wondering .....

Thanks.

Attenuation. Theres figures in one of the eircom docs, cant find it now though. It'll be done from VDSL DLSAM to NTU, so your current ADSL figures dont necessarily "match up" as its 2Mhz vs 17Mhz.

I'm about 1.6 i think from the cab and I'm getting 11.6 down but i just did a speedtest on the wireless and getting shocking speeds, worse than normal

Thanks ...... I was wondering if the ADSL figures could be used as an indication, but apparently not.

They're a good guesstimate. Use the kitz calculator to convert your dAttenuation to loop length. Then compare to the VDSL charts.

I had estimated my line length to exchange as ~3Km. The Kitz calc tells me it is 3.3Km. (46db)
I get the expected ~5Mb/s d/load these days .... it increased somewhat a few months ago.

There is an existing cab ~2Kms from my home.
This is mentioned for upgrade to e-fibre by year's end (we'll see).

It is unlikely that my line is going direct to the exchange as to do so would mean going under the existing cab

On that basis I might expect my d/load speed to increase to about 12Mb/s once the cab is converted.



Am I reading things correctly or maybe getting mixed up with different technologies?

ED E

Nope that's right. Assume that 3300m is right, measure the dist from exchange to cab by road on gmaps. Subtract that from 3300m to get your vdsl loop length. Hopefully its within 1800m.

Measuring with G-Earth I get a total distance from house to exchange, of 3150 Mtrs and not the 3300 calculated.

It really depends on where the difference is generated ..... my measuring, or maybe older wire from cab to exchange?

Honestly it seems that I am about 2Kms from the cab ... but with good copper running in a duct to my boundary wall.

Comment?

Thanks.

One thing I noticed from the above calc is that the wire thickness must be higher in the rural locations not 26 AWG but more like 24 AWG. I know I'm exactly 2.5 KM from the exchange as the poles follow the road. With my attenuation figure (taken from two diff modems) of 26 dB, the cable loss default they use of 13.81 is more like 11 for me to get the same distance calculation. Whether that allows me to get the min VDSL profile is unknown but let's hope! It'll be an improvement on ADSL1 anyhow...

Supposedly P&T and TE back in the day way over specced some of the cabling, one of the posters here knew a bit about it. You'll probably find it varies a lot from era to era of when the main cables were laid or hung.

Drop wiring also varies a lot, sometimes its bell wiring from ETU to NTU.

I'm 1.6km (verified the run with a few Eircom techs) from the cab and I get;
RX:30719/ TX:3344(Kbps)

As said before, depends on the copper etc. I believe the copper which connects my road to the road with the cab was re-ran prob about 6~7 years ago. Some of the copper on the road itself was also replaced in the past few years due to tractors hitting/snagging the cabling.

Note, I had to use a contact within Eircom to allow me to order up eFibre as I was such a distance from the cab

I was very lucky in that i knew someone in Eircom too, however they couldn't connect me to the fiber, and Vodafone could although i should be getting the same speed as you and I'm not.

It would appear that some, if not all, decisions are made based on distance, if it required intervention by a personal contact.

I suppose Eircom are not bothering to test but basing their initial decisions on distance, at least without some 'extra' nudges from the right places.

Attenuation is a product of distance, so when Kerbdog says distance its the same as saying high attenuation.

It is also affected by the quality of the copper I believe.

What I was trying to get to is this .....

if Eircom says e-fibre is not available due to distance but yet when a personal intervention is made it becomes available, then what allows that to happen?

The distance or attenuation do not change ..... unless a guess at attenuation was made based on distance and when measured was in fact better than the guess.

Else it is who you know that makes the difference ..... and I was rather hoping it was not that.

I do not understand what causes a refusal that can be overcome by a personal contact.

ED E

Borderline results.

Say 30dB gives a prequal raw value of 6Mb. This will fail to prequal for the 7Mb min. If you call a sales team they'll say nope. But if you know somebody high enough they can presumably ignore the test and issue it anyways. The line is still gonna be slow, but it could get you up from say 1Mb Adsl. But any degredation and sync will fail, its a borderline connection.

Please ignore. I seem to have picked up a quote from another thread and do not know how to get rid of it.

The prequals for fibre seem to vary a bit.

I'm 488m from the cab and my prequel gives me 47.6meg
A friend up the road @ 922m is getting a prequel of 57.8meg
Cable routes have been confirmed.

Something is way off or I have a line problem.

Kaizer, I wish I had a problem like yours.
