    Vodafone anyway have it set so the downstream SNR target is 10db. It's unnecessary. Before the latest updates I was connected for weeks with not one disconnect at a downstream SNR of 6db. I asked them to change my SNR target to 6db but they didn't understand what I was talking about.

    Exactly the same experience here - right down to the phone call and the feeling that the person I was speaking to couldn't appreciate why I was asking for a change in target SNR. For me too the connection was always stable at 6 (even when it went a little less than that) and I'm fairly certain that it would make the difference between the highest available profile to me being the 25Mb one I'm on now and the 30Mb one I've always been just short of.

    EDIT:
    Also I used to have 5Mb upstream when the SNR was targeted at 6 - now that it's targeted at 9 I only get 2.5Mb.

    Its CPE defined isnt it? Probably hardcoded into the firmware.

    Hi Ed. I don't what CPE is but it seems that not all providers are targeting SNR to a minimum of 9. I'd be interested to see SNR stats from people 1.5km+ from the cab who are with the different providers.


  • Registered Users, Registered Users 2 Posts: 36,169 ✭✭✭✭ED E


    Modem/Router. I think the SNR target is built into them. Arctan might know.

    It'd be interesting if any boardsies had a Draytek they might be able to play with it. They'd also have to be set to a high rate adaptive profile for it to go that low.

    I'd formed the impression (partly from info in this thread and partly from speaking to TS at Vodafone) that the SNR is set as part of the rate adaptive profiling of my line. I don't know what system does this or who is responsible for it but I had pretty much ruled out my router as being responsible: Its firmware updated more than two weeks before the target SNR changed (which I'm tentatively thinking resulted as part of the implementation of G.INP) and I've already changed the firmware to older versions and back again to see if it makes a difference: it doesn't. (The experiment did have a few curious side effects though - btw: if anyone wants one of the 12 most recent versions of the HG658c firmware they're available from Vodafone here: http://publicacs.vodafone.co.uk/firmware/IE/Huawei/HG658c/)

    Well I was a month on a SNR of 6db before the G.INP update and my modem hasn't changed.

    I asked the Eircom rep I have been in contact with to tell me the line distance but I didn't get any feedback - perhaps he can't actually say and only an engineer can. My attenuation, by the online checkers, puts me further than I actually think the line is. My latest best guess is the line length is 1.25Km (as I was told it actually runs to one cabinet, but since that was full it then runs back on itself to another and Google maps gives that as the distance). I think the joints and the internal cable run of 40m results in the higher attenuation of 25dB for the distance. This still ties in with Eircom initially saying I could not get fibre as I was over 1Km distance from the cabinet.

    Thanks for trying to get a reading on your distance - I'd still be most interested to know if you find out. In my case it was only the visiting engineers who could tell me alright. Your explanation would go a long way to accounting for your attainable speeds though (at least, based on my patchy knowledge of all this, I imagine it does). I did a very careful check of my own (seeming) physical distance from the cab using Google Maps as well some time back - literally plotting telegraph pole to telegraph pole and, coincidentally enough, I also got just over 1.2km. The line disappears under the ground some 100 meters from the cab so I have to assume that the remaining 700m odd is the result of the very circuitous route it must take to travel those last 100m as the crow flies.

    Is it bad?

    At times with vectoring enabled, FEC and CRC errors will be in the thousands. As the line is sampled for interrupting signals and an antiphase of that signal is introduced to counteract the interrupter, in essence this registers as errors. Taking into account that vectoring has significantly increased the frequency at which transmission occurs and recurs there should be no adverse affects on your line.

    Got the UK edition on the 7360 on Monday with a beta firmware.
    No improvements anywhere. But I'm giving line diagnostics back. I'm working with Digiweb, I think they are working directly with the firmware team in AVM.

    I'm guessing if the issue is resolved they shud release firmware for ur model also.

    As far as I can tell, Eircom / Telecom Eireann / P&T, don't use the 26AWG cable that that site presumes. Therefore the attenuation / Km is probably quite a bit out.

    I'd stand to be corrected on that if we have anyone knowledgable on the type of TP cable Eircom use(d)?

    Visited my parents this weekend, they're pretty far from their cabinet and before vectoring was enabled they were getting 12 down and 1 up (a vast improvement over their old DSL).

    This weekend though their speedtests are 20 down and 3 up, very nice! Vectoring is effective even on very long lines it would appear.

    Would you be able to hazard a guess as to the distance from the cab they are? You can get down to street level on the fibre map here http://www.eircomwholesale.ie/Our_Network/. Tick the Live box on the right.

    My line got reprofiled last night.
    Suddenly went from 10 / 40 to the maximum the line will take which is 20/70 roughly.

    Not bad at 650m from the cabinet!

    Not bad! That is super.

    This VDSL and vectoring really is fantastic news. It looks like superfast broadband should be a reality for the majority of people in urban and semi-urban areas.

    That is fantastic news, we finally have the urban broadband problem fixed.

    Now we just need rural Ireland sorted.


  • Registered Users, Registered Users 2 Posts: 2,191 ✭✭✭MBSnr


    ^^^
    Yeap have to say I'm more than impressed with the Eircom VDSL connection I have at work! A guy in Eircom told me that anyone within 300m of a cab should expect the 100Mbps profile with vectoring (obv. if their line is suitable).

    We just need more reports of lines on longer runs (which unfortunately is a bit lacking but should increase in time...). As I mentioned before, I'm hopeful that vectoring has provided a chance of the reach being extended out beyond 2Km for suitable lines (esp. those directly connected lines to exchanges). It seems (based on the limited reports/versus longer known distance) that the speed profile used has been a pleasant surprise - in that it's more than was expected.

    I've seen the stats for a connection with Vodafone (easily within 300m) still on the 70Mbps profile - but didn't get to see the net attainables - so perhaps vectoring is not enabled there. I don't like the way the HG658 doesn't show them on the main status screen unlike the F1000....


  • Closed Accounts Posts: 9,088 ✭✭✭SpaceTime


    The small distributed cabinets make a lot of sense with population distributions like we have here in Ireland.

    Even our urban areas are fairly low density.

    I'm within 2km of Patrick's St in Cork but it's an old mostly Victorian (some Georgian) area with lots of space between houses. UPC coverage is patchy. They've done a terrace here and there and some individual houses that paid for ducts in the 80s.

    So VDSL has been a massive improvement. Entire area is adequately covered with about 5 cabinets.

    Yes vectorised VDSL2 is proving to be quiet a good solution for Irelands unique challenges.

    I'm also looking forward to the rollout of VDSL to exchange only lines and to see how VDSL handles longer lines in rural Ireland.

    In the longterm, I'm hoping they will introduce smaller, pole mounted VDSL cabs, that might help serve rural Ireland even better.

    Ohh pole mounted VDSL cabs.... they exist? About 300m from my house all the lines from the exchange are terminated on a pole (with the weather proof connectors) then disappear underground for a few hundred metres under power lines.... That's the phone line for nearly every house 2km and further East of the exchange. If there was ever a location for a pole mounted VDSL cab then that's it....

    There are pole mounted and also underground ones that can be fitted into vaults.
    However, I haven't seen one from Huawei yet. I'd suspect if they're going to be used here they'll probably stick to the same supplier to keep it all in one maintenance contract.

    The Huawei gear is proving to be very good though and they've really innovated on VDSL2 stuff. Seems it's getting excellent reviews from operators that have used it elsewhere too.


    That's a "mini cab" https://www.ecitele.com/OurOffering/Products/Pages/MiniCab-64V.aspx for example from ECI.

    Supports up to 64 lines and you can mount it on a pole or in an underground vault. They require no cooling or anything like that, it's all passive.

    Obviously, for eircom it would need to support the same kind of vectoring and it if were from the same vendor as the existing small cabinets, it would make a lot of sense.

    Ohh pole mounted VDSL cabs.... they exist? About 300m from my house all the lines from the exchange are terminated on a pole (with the weather proof connectors) then disappear underground for a few hundred metres under power lines....

    Yup there are some mini pole mountable VDSL cabs. As you say excellent solution for a situation like yours. Here is an example of a 16 port model:

    http://www.zyxelonline.com/showpic.php?categid=2&picid=84&view=1

    I don't think they will look to do this for at least another year, maybe even two or more. There is too much low hanging fruit of standard VDSL cabs and exchange only lines to do first. But I'm hopeful they will.

    Ireland's climate actually has serious advantages for this kind of technology (and poses a few problems too)

    Advantage:

    It's very temperate and cool meaning that you don't need complicated air conditioning and cooling systems on most outdoor plant. That's a huge issue in most other countries as on warm days it can easily go >30ºC and in winter you can risk freezing temperatures which can cause problems too.

    In general you should be able to install quite compact cabinets as there are no real heat/cooling issues whatsoever and most equipment would be able to cool completely passively all year.

    The biggest issue you have to contend with in Ireland is waterproofing as we get a lot of driving rain, drizzle and plants that will happily penetrate enclosures i.e. moss, ivy etc.

    So, all in all it's not a bad place to use outdoor equipment and is far more suited to it than say Spain, most of France, or California in some ways where you'd have serious heat issues. In fact, almost everywhere else other than Ireland, Britain, Iceland, New Zealand, Western France and maybe parts of Western Scandinavia etc tends to face far more extreme weather.

    BTW: Really impressed with eircom's ping times! They've improved dramatically in the last few months.

    IPoE helps there as your packets go direct to their destination, not to an access server that could be half way across the country and back.

    Any way of finding out when your cabinet is going to get vectoring enabled? Like a roll out plan?

    AFAIK, they're all enabled at this stage.

    Check your modem stats and see if your 'attainable speed' has gone up. You could still be on a slower profile. In that case, you might need to contact your ISP's technical support.

    Eircom seem to be re-profiling their own customers automatically (bit by bit), but that doesn't necessarily mean that other ISPs using the cabinets are necessarily doing the same.

    The profile is just the speed that your account is set to rather than what the line's capable of.

    When i originally got VDSL months back it was synching at 40mb , recently this dropped to 36-38. I am about 1 KM away from cab. My SNR has not changed signficantly or attentionuation leading me to believe vecitoring has not been enabled?


  • Closed Accounts Posts: 9,088 ✭✭✭SpaceTime


    At 1km from the cabinet, that's probably within the norms.

    There are two issues :

    1) Noise - vectoring actively cancels this. So on shorter lines this can see big speed improvements.
    2) Attenuation - signal fading and becoming weaker as it passes through a medium i.e. copper wire in this case.
    Unfortunately, at 1000m away from the cabinet, that's a lot of copper to get the signal through and vectoring doesn't do anything to reduce attenuation.

    It's possible the line has vectoring switched on but that it's just having no impact on your speed due to your distance from the cabinet.

    Yeah maybe will check when home. Also measure distance from cab. I think it's probably less than 1km

    Check it out, but just remember that the distance to the cab may not be the distance along the road.

    Occasionally phone wiring can take some odd routes for historical reasons i.e. you might have a line going to a cabinet that might have made sense in 1967 when your house was built but doesn't make sense now due to other local developments.

    You can also find that the cabinet could be directly opposite your house, but the wiring takes a scenic route through your estate (happened a friend of mine! - they can see the cabinet outside the window on a green outside their house but the wiring goes right around the outside of the estate and back in the main entrance adding about 600m to it!)

    Telecom/P&T/eircom also used various different gauges of wire over the decades (although most of it seems to be very good quality surprisingly enough. The main issue in Ireland is that the lines can be VERY long). However, you can get slight variations in attenuation so, it's not always a 100% accurate judge of distance.

    I am with VF and waiting patiently for vectoring to be enabled, I have the latest frimware in modem, but its bridged. When I check eircom site it says line can take 50mb, it used to say 40mb but when I check VF site it says up to 100mb. I am 800 metres from cabinet and get around 35mb/8mb but when I got fibre first it was a steady 38/8. Pings have improved on speedtest and I notice GALWAY has been deleted. I am in clare.

    If I ring VF tech support should they be able to up the profile or is it still like the old days they wait for eircom? In other words do I just hang on?

    The roll out has been a shambles so far.

    Ring em, if the stats are good they'll do it in a few minutes.

    What roll out has been a shambles?

    I haven't had vectoring enabled yet, I think I on one of the big cabinets that needs different tech.

    To be fair to them, the rollout hasn't been a shambles. It's actually been very quick and very smooth.

    AFAIK, the entire NGA rollout is using a standard type of Huawei cabinet. There was an early trial in Dundrum and Sandyford in Dublin that used Alcatel cabinets which were an earlier design - very large white ones rolled out about 5 years ago at this stage.

    I had assumed they'd been replaced with the standard Huawei ones that were selected in the end.

    The shambles is that there has been no news by VF about vectoring, all they have done is change theIr website to show " up to 100mb" which I detest.

    Eircom did a press release aeons ago and nothing else. One has now way of knowing if local cabinet has been enabled so you are at the mercy of the provider.

    Eircom will understandably upgrade their customers automatically but the rest of us are faffing about waiting for news.

    The roll out was expected to finish end of March 2014.

    What eircom could do and should have done was mark the cabinets on their map as enabled for vectoring as they went along. They could also do a few updated press releases advising of progress.

    I am only ranting as my line went bad as vectoring was being rolled out but a great guy on VF tech support told me just now, line has a fault so until that is fixed no point in enabling vectoring but he has put my speed back up to 39mb/8.5mb, however until fault is fixed this may drop again. Its now over to eircom.

    I was expecting vectoring by end of March and its nearly June now. I know I should not moan but a lot of the blurb promises great things.

    What happens is vectoring is enabled and higher speed profiles are made available for the lines by eircom wholesale. It is then up to each retail operator to apply the higher profiles to their customer's lines.


  • Registered Users, Registered Users 2 Posts: 5,577 ✭✭✭swoofer


    jd thanks, does that mean VF should do it automatically? But, as in my case, if there is a line fault they will do nothing until I ring them???

    Do they still contain the original Alcatel-Lucent DSLAMs though?
    It's quite possible that eircom re-kitted them out with Huawei gear since. Or, at least have AlcaLu gear that's to the same more up-to-date spec.

    The white box is just a cabinet with racks. It's what's inside that matters.
