Odd issue with trying to order eFibre. Anyone help?

Nonoperational

A few months ago I got a letter saying eFibre was available in the apartment where I live. Got around to ordering it and got a phone call today...

Apparently the exchange I'm connected to, DGS (douglas) only has "3 eFibre customers and they have really bad speed" and because I'm over 1000m from the cabinet then my line is not suitable for eFibre.

A few things about this...

1) There is a cabinet around 200m from my house, it's on the map and I've seen it in person. It is DGS - Entrance to Rathmore Lawn.

2) The eircom line checker says I can get 50Mbit eFibre.

Anyone have any idea why this might be happening?

Thanks!

I've ordered now with Vodafone and they said they can see no reason it won't do 50Mbit. Fingers crossed. Better deal anyway.

yeah defo sounds like bull****, im over 1000m from mine and sync at

Line Rate (Down / Up) 50174 Kbps / 20479 Kbps
Noise Margin (Down / Up) 9.6 dB / 8.7 dB
Attenuation (Down / Up) 14.1 dB / 5.2 dB
Power (Down / Up) 12.4 dBm / 1.3 dBm

currently getting a ping of 15ms, download of 46.73Mb and upload of 19.26Mb

I really don't get it. The eircom rep on boards said the limit is 150 Meters....

Anyway, lets hope Vodafone can sort it.

150 metres for what?
I'm 350m from the cabinet and I'm getting 70Mb sync, 67Mb actual download. VF customer, so the copper on my line is extra special:rolleyes:

Eircoms call centre staff are unreal, ring them twice and you will Get contradicting answers those two times alone. Give them another whirl and see what say.

This is the link to the Eircom reply on boards.ie

I can't understand it at all to be honest.


I've ordered with Vodafone, have enough of them.

Nonoperational

And still the official Eircom response is that eFibre is only possible under 150M from a cabinet. Extraordinary.

I see the penny has finally dropped in the eircom support board:rolleyes:

Vodafone technician coming Monday. Hopefully the mysterious reason my line isn't suitable for fibre won't reveal itself!

Installed. Pretty unbelievable from Eircom.

What are your speeds like in the end?

Nonoperational

I'm syncing at 40Mbit down, but I'm going to give Vodafone a call tomorrow to up the profile a bit. My SNR and attenuation suggest I could do a bit better than that. Maybe 50Mbit....

Even as it stands it's 4 times what I was getting before. Very happy with it.

fat-tony

I looked at your sync figures in your other thread - SNR is ok, but note it will disimprove at higher sync speed. Your attenuation at 12dB is more than twice mine is at 8dB. You say that you are only 200m from the cabinet? I'm 350m and have lower attenuation. Is it possible that the path from the cabinet to your house is much longer?

dazdrog

ive a higher attenuation then you have (12dB) mines 14dB and i get the following



Line Rate (Down / Up) 50174 Kbps / 20479 Kbps
Noise Margin (Down / Up) 9.1 dB / 8.5 dB
Attenuation (Down / Up) 14 dB / 5.1 dB
Power (Down / Up) 12.4 dBm / 1.1 dBm

so you defo should be able get more, my closest cab is 600m from me but my line length is around 1000m, strangely enough tho, theres also a cab bang on 1000m from my front door following the only path that the cables take from my house

Ya it must be... There must be quite a long route from the cabinet. Looking at my figures I'd say it's more like 500m. Still inexplicable why Eircom refused to do the job. The guys that came to install it said they get very good speed up to 1km from the cabinet.

Thanks, ya I phoned Vodafone and he said the order has not gone through yet but the phone back tomorrow and they will tinker with the profile...

@dazdrog - attenuation goes up (and SNR goes down) the higher the sync speed, so you might find that your attenuation would be better at a lower speed, but line quality and the quality of the internal wiring and how well the connections are made all have a bearing on your measured attenuation and SNR so individual circumstances will vary. When I was first connected to fibre in November I had SNR in the 8dB range, but replacing some of my house wiring I got the downstream SNR to 14dB.

ive no problems with my line at the speed im synced at, my SNR is fine and my connection is always stable and has never disconnected once, why on earth would i lower my speed?

Attenuation is fixed buddy. Line length(and cable quality/guage) = attenuation.

SNR and Sync speed are variable and inversely proportional.



Its worth noting that while SNR room may be there for a higher speed due to other conditions attainable sync rates may not allow for the next profile up. Each line is very much unique(the big downside to UTP).

fat-tony

Attenuation is related to frequency for any given line (cable) type. Depending on the profile in use - ADSL VDSL the frequencies in use change and attenuation increases for any given length. It's not the same as DC resistance.

dazdrog

still why the suggestion to lower speed? ive no problems

No, but we are talking within ADSL here. In those circumstances attenuation as measured by the DSLAM will not change unless a physical fault becomes present.

I didn't suggest you should lower your speed. You mentioned that you had higher attenuation but had higher speed than the OP and I pointed out that circumstances differ and that line quality is more critical at higher sync speeds. The OP's SNR would go down if he was put on higher speed, but it might be stable and perform ok. The only way to check is to get VF to put him on the higher speed.

I'll let ye know what happens when they check it out tomorrow!

Accepted the 50/20 profile no problem. Vodafone tech support aren't bad so far. Hopefully won't need them anymore now!
