When might Eircom to enable vectoring on their eFibre/VDSL service?

Is their Vectoring rollout nearly finished now at this stage?

i doubt it as my local cab aint fully vectored, ive had these stats near a year, but yet its claimed by vodafone im locked to 50/15.

10 months ago my snr was 6.0, with a sync speed of 50/20. so id say im still waiting as the jump in snr is nowhere near as large as most people get.

+ if i check a address thats right beside my cab it says the max package is 70/20 , so im doubting its fully vectored as it should show as 100/20

Downstream line rate (kbit/s) 50176
Upstream line rate (kbit/s) 15360
Downstream attainable data rate(kbit/s) 69532
Upstream attainable data rate(kbit/s) 23908
Downstream SNR (dB) 14.4
Upstream SNR (dB) 14.4

There are definitely many cabs not vectored!

I'd say your cab has been vectored if your SNR has more than doubled from 6 to 14

Dazdrog, do you mind me asking which cabinet you are served by? If I remember correctly, you might be on the same cabinet as some of my relations. DBC 027 I think.

How do you find your cab number?

find it on the map here, http://fibrerollout.ie/where-and-when/ - click on your nearest cab and it will tell you its 'name'

well i wouldnt say its fully vectored, ive seen people with the same stats as mine go from a attenuation of 14.2 with snr downstream of 6 and they jumped to around 28dB

+ my cab only shows as a max of 70/20

What do you mean by fully vectored? Either it's vectored or not. In my limited knowledge of vectoring the idea is to reduce snr (crosstalk) between the cables in the cabinets. When that is done the other line values, attenuation etc will adjust in proportion to the new snr value which in your case has now improved from a very poor 6 to a quite acceptable 14. How far are you from the cabinet?

failing that, it's usually written on it on a yellow sticker

just about 600m following the cable route along the paths from my house, theres only one way the cables come into the estate, my line attenuation says otherwise tho, looked more like i was connected to DBC1_040 (thats about 1000m away) but i had a kn tech confirm i was indeed connected to DBC1_046

dazdrog · 11-09-2014 04:55PM

The cab im connected to has grown a foot overnight. Its had a extension about a foot high added to the top of it, ill get a pic on way by it again.

That's a copper extender, its used to make room for the cables over to the fiber cab.

No this is the vdsl cab labeled dbc1_046a and new part dbc1_046b

That's so weird looking, is that perhaps for more lines to connect to it?

What exactly does it do?

thats what im guessing, theres well over 250 houses served by that one cab

Yeah the bit on the top is for more lines

KOR101 · 11-09-2014 07:21PM

I was on 20/50, and could see attainable of 24/90 (checked many times) , so I called them and they did a manal prequal.

Witihn a couple of days, i had a new profile 20/80.

I just checked my attainables this morning, and it shows 24/99, and I have a new profile 20/90.

Is this just normal variation, or is the vectoring 'refined' over time?

Your on a rate adaptive profile, what that means is as your snr (signal to noise ratio) changes as the day goes on your sync speed will vary. This would be why you see changes in sync speed

KOR101 · 11-09-2014 09:39PM

Okay, so is there anything else over the immediate horizon than vectoring.

Nonoperational · 11-09-2014 10:30PM

Nope

Ah ok, thats the first time Ive seen that done. Normally busy areas get a second cab. They way the cabs are wired its hard to guess how much extra capacity that'd give.

They need to extend the existing. Extra space is required because they are not just running jumper cables from exchange side to distribution like has always been the case, they now need to loop it through new blocks which go to the fibre cabs.

sparky63 · 11-09-2014 11:22PM

Its used to add an additional 200 pair copper link from the VDSL cabinet to the copper cabinet. Its called a top hat.

ED E · 11-09-2014 11:27PM

What I'd thought originally. Only thing though is I've seen CCP cabs with them when their counterpart VDSL cab doesnt have one, so why the need in some cases and not others, unless they're adding line cards?

sparky63 · 11-09-2014 11:36PM

It was added first to ccp cabs that didn't have the room for the vdsl splitters. Now it's being used to increase the copper link in the VDSL cab as there is no space in the VDSL cabs for an additional link. Shows that the uptake in fibre in a particular cab far exceeded their expectations.

Depends on how full the cab is, some have space, others need extending. The vdsl cab is new, would be the required size, no need to extend it

has to be for more lines, ive just added up roughly how many houses it covers

2 estates around 100 houses each, then two smaller ones with around 30+ each then about 10-15 houses out a country lane and a college of further education

so say near enough 300 houses served by the one cab

ive also just noticed that my line attenuation is up from 14.1 this time last year to 14.3dB now

When might Eircom to enable vectoring on their eFibre/VDSL service?
