    I'm guessing it means broken, not working, useless etc.

    Something's not right here.. with an SNR on my downstream of 20+dB, I should be getting more than this, surely?

    I was getting 30/8 until today, now suddenly I'm on 20/10.

    Ring them and ask for a higher profile. You might get 100Mb.

    I rang the other day and was told I'd be able to get 92mbps - however was also told my exchange or cabinet isn't upgraded yet.

    @daffy - your signal attenuation is very high at 26.2dB and if you look at the D1, D2, D3 line attenuation it is very high at the higher signal frequencies. You are either very far from the cabinet or there is a high resistance joint or other fault on the line. The SNR is good, granted, but the attenuation is very high. If you think you are reasonably close to a cabinet then you need to start talking to eircom to investigate a possible fault.

    Eniskillen often reports latency of 0ms, when its at least 6ms to the public internet something is up there. Sometimes it reports figures that look right but as its erratic I tend to avoid it.

    I have the same value for D3 on mine and my attenuation places me 1.7Km from the cabinet. His looks to place him around 1.8Km from the cab.

    Hello all,

    It was I who started this thread and I thought I would look for advice on what you all make of the following

    The image was from August 2013 shortly after the VDSL was installed.

    I am thinking its a fault on the line. The building next door, which is futher away from the VDSL cabinet has improved in the same period.

    Distance from cab is around 800 meters.

    What do you all think?

    ^^^

    Your Up/Down in Aug 2013 was 7.167 Mbps/ 25599 Mbps and still today it remains the same. But your line attenuation of 20dB has increased to 29dB and your receive power has changed from -8dB to -17dB, so perhaps indicating an issue with the line.

    Is there only one cabinet near you?

    Yes speeds are the same, cant get a bump in speeds because the account name has "&" in it.....believe it or not! Working on getting that resolved.

    Yes, another cabinet is near but about the same distance.

    My CRC errors are way up too. Can anyone explain what's going on? SNR gone from 6 to 10 but attainable rate gone down from 60 to 50ish and CRC errors increased!



    Only positive is ping gone from 24 to 11.

    Profile is 17a and inp is 29 in both directions. What exactly does this mean?

    Cheers.

    OK from my limited understanding of reading it on google (I stand to be corrected by someone more knowledgeable)

    Profile 17a - means you can get upto 100Mb
    http://en.wikipedia.org/wiki/Very-high-bit-rate_digital_subscriber_line_2#Profiles

    INP
    This is the Impulse Noise Protection (Vectoring they are calling it at a guess) used over the phone line copper pairs. It was INP 2/3 for most people but now INP 29/30. It's apparently measured in DMT (Discrete Multi-tone) 'buckets or bins' and each DMT can carry a number of bits - more bits = more data rate down the cable. The non vectoring noise cancellation protected 2 or 3 bits per DMT Symbol (from noise). Post vectoring turn on it now protects upto 30 bits.

    Or at least I think so... Quite how that all adds up - I dunno....

    I don't think vectoring is connected with impulse noise protection as such. My (limited) understanding of the vectoring process is that it reduces crosstalk on the line (where the signal on a neighbouring wire pair interferes with others) such that the ratio of wanted signal to unwanted signal (noise) is improved. This means that higher frequency signals (ie more speed) can be received further from the cabinet. So, homes nearer the cabinet can get a boost in speed above the 70/20 potential of profile 17a and it extends the reach of reasonable speeds beyond the initial 1k - 1.5k distance limit set by eircom.

    I'm getting very technical here, but my D2 downstream attenuation is marginally higher than my D3. Is there an issue somewhere I wonder?

    Seems strange - attenuation goes up as frequency increases for a given cable type.
    I'm wondering about the value of all of these posts of attenuation figures and how they are measured and the fact that we are calculating distance from the cabinet based on some calculator published on one or other website. Without a stated reference frequency, attenuation is meaningless other than as a relative indicator. The kit (ISP modem) is mass produced in China to a price point and is unlikely to be finely calibrated. It's hardly scientific and there would seem to be a lot of speculative posts as regards potential speed estimates. I suppose it's good for boards to have a very active forum, but there are times when I wonder what is the purpose of all the speculation about potential speed. I'm guilty of it myself but I'm getting 70Mb download and have just been vectored, but would I notice if it got bumped up to 100Mb - meh :P

    I'm just home from sunny Lanzarote where I had to grin and bare very unreliable 3m/bit for the odd bit of work that i had to do for a week ;)

    Home to my cabinet vectored and amazingly low ping times which is a nice surprise. I'm hoping my stats are strong enough for a nice boost in downstream speed!

    I am thinking its a fault on the line. The building next door, which is futher away from the VDSL cabinet has improved in the same period.

    Distance from cab is around 800 meters.

    What do you all think?

    30mb/8mb is all your line will hold... call and get the eircom agent to run some line tests to check for faults

    Could well be! We really need an expert here :D

    vectoring reduces cross talk

    the next stage after vectoring is called bonding

    that reduces impulse noise and channels a virtual 3rd signal inbetween the copper pair... if on 100mb/20mb now when bonding is introduced speeds will hit upto 200mb/30mb

    As has been stated in thread several times, its very very unlikely that eircom will go for bonding. The next step is FTTDP or FTTH.

    I'm still very curious what happened to my line. When the SNR was 6 the attainable was 63Mbit. It's now 10 and the attainable is gone to 52Mbit!

    Very strange, and seems to have happened to people in Cork more so than elsewhere!

    Attainables arent everything. You can have a 5Mb ADSL2+ sync with 9Mb attains, set it to 9, the attains jump to 12. Its only a best guess from the broker process.


    That said the behaviour is weird. Have your had your provider run VDSL line tests for you?

    It happened overnight this week and was accompanied by a halving in pings which I assume was vectoring being turned on. Other people have had the same issue. It's not a line issue I'd imagine, more a profile change or something along those lines.

    Vodafone probably wouldn't be interested as the line is still syncing at 50Mbit.

    nice one... in summary (for those too lazy to follow links) go to status > WAN > DSL and there's a bunch of rows in the table that are set to display:none... so use a browser inspector to show them and voila... it'll show attainable data rate...

    I just signed up to eFibre and was expecting better speeds than what I'm getting below, from the stats below does it look like the line could be synced at a higher speed?
