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

BArra

Thank s, its the number and I'm around 200m so it should be decent enough speed, touch wood

Ah-Watch

My line prequalled for a month prior to going kuve and said beforehand it would take 100. When it went in it prequalled at 90. We wont fight over the 10 meg

Line attenuation wouldn't be dependent on the type of signal... It can be reported to increase if higher speeds are enabled on a line just because higher frequencies are being used and the average attenuation across the used bandwidth is higher.

I'm at a loss as to what this has to do with my post.

You had said that vectoring would increase attenuation but the kind of signal or noise that exists on a line has no impact on the line's attenuation value. I guess it can impact on what some routers describe as signal attenuation and many routers just treat the two as the one and the same.

My point is that attenuation increases are not really connected to vectoring but possibly to the speed increases and higher frequencies used as a result. Depending on what kind of attenuation the modem is reporting.

Its a bit dry but : http://forums.thinkbroadband.com/technical/4280862-signal-attenuation-vs-line-attenuation.html?page=1

Interesting some more results =

My brother's line is going from 50 x 16 to 90 x 20 now with vectoring upgrade. Pretty nice result! This is a 400-450 metre long line.

My other brother is only gaining a little from 25 to 30 this is a really long line though.

and my sister is only going from 30 to 40 also a long line.

You know it is interesting how quickly expectations change. Looking at this thread and the UPC upload thread, we (myself included) are complaining about upgrades of only 5 to 10mb/s. Just two years ago and still many people in rural Ireland, would kill for a 5 to 10mb/s upgrade!

Just something to keep in mind.

Got vectored as well. Had initially got 70 down but this degraded to 50 down over time. Now have 80 down with the attainable saying 90+. 400-500m line.

Low SNR, if you notice instability drop it back to 80.

I'm assuming going by these stats I'll be able to reach 90 or 100 / 20 up. I'm on 70/20 at the moment.

Have an odd issue now though. I get the speed above wired directly to the router, but my download via my homeplugs and over wifi have both decreased since the speed was upped. Both cap out at 30Mbps whereas I was getting near enough the full whack with the homeplugs on 50

Your upstream and downstream signal to noise ratios are dreadfull and thats with a link up time of 12 minutes, i'd be concerned as the longer the modem is left on that you will have a lot of issues. The thing that concerns me is before your increase your link up times were in minutes. A better gauge of how your line is performing with vectoring, is to monitor line stats over an extended period, with no reboots or not being switched off. As a better analysis of attainables is when the modem is left on for a prolonged period.

Thanks, I'll keep an eye on it and if there's any instability I'll get them to roll it back to 80 as was suggested. The SNR has increased slightly since I took that screenshot. It's synced at 85, the up is closer to 9dB and the down is over 7 dB for the moment.

Anyone have any idea why the homeplugs would have decreased in speed? I did a speedtest over them right before they upped the profile and was getting about 40Mbps but, ever since it hasn't been managing to get over 32Mbps

I rang them and they said they'd put me on a 100/20 profile and it looks like they have but there hasn't been a change in speed at all . Does it take a while or whats the story? Thought I'd see an increase into the 80's at least?

Meant to say I was on a 70/20 profile and get in the mid 60's for download

Some really interesting news about vectoring from Eircoms submission to the DECNR about the national Broadband Plan. One of the new technologies they say they currently have in development is:

Node Level Vectoring – this is a technology being developed which allows Vectoring to be deployed in two DSLAMs in a single cabinet. Vectoring itself has already been successfully deployed in over 80% of the eircom network: this functionality allows customers on FTTC to obtain speeds of 100 Mbps instead of up to 70 Mbps in non-vectoring cabinets. The non- vectoring cabinets in the eircom network are cabinets that currently or are likely to require a second DSLAM due to demand. Dual DSLAM cabinets require the node level vectoring technology to deploy the vectoring for this subset of customers.

This reveals a couple of important points to us:

- Vectoring has been enabled in up to 80% of cabs
- The cabs that haven't received vectoring yet are in areas with the most demand for VDSL.
- Eircom is working on a solution to enable vectoring on these remaining cabs

This is probably part of the hold up for exchange launched VDSL as they have to get NLV down before that can properly go ahead.

Nope. This isnt ATM based with the overheads that introduces. Effective throughput of a 50_20 line should be around 48 and 19Mbps.

In any case, he was talking about the increase when his DLSAM starts vectoring. This will bring his attainables from 51Mb to XMb, probably around the 60Mb mark or so, but the odd time a lot higher.
