FTTC when super close to exchange?

Discussion in 'Broadband' started by www.GymRatZ.co.uk, Jul 31, 2013.

  1. Hi Folks.
    Looks like FTTC has been put forward as scheduled 1/09/13 which is good
    however I'm wondering whether my proximity to the exchange will screw
    things up? the actual line length between building and exchange is
    around 200m which is brilliant for ADSL2+ with download of 20Mbps but
    there doesn't appear to be any old-style green cabinets in the area and
    as far as I'm aware the lines all group together at the top of a pole
    then drop down and go under the road back to the exchange.

    Anyone come across this scenario before? Is there a chance being too
    close to the exchange means I can't get FTTC when it's in the area?

  2. I am going to make a probably rash assumption that the ALSO put the guts
    of a green cabinet INSIDE the exchange for 'extremely local' customers,
    i.e. there is a dslam equivalent in there that they will use to serve a
    500 meter radius.

    After all FTTC is simply a way to extend fibre backhaul closer to the
    end user. The last 200m is till a form of DSL AIUI

    Yup. found a tekky dokky. VDSL2 is up to 100Mbps and the range extends
    to a couple of hundred meters at that speed over single twisted pair. a
    little speed loss up to 300 meters than it really starts to plummet,
    at 1km its down to 30Mbps..

    So if BT play the smart card, they simply put a VDSL2 DSLAM in the
    exchange to handle the 20 odd customers less than 300m away.

    Of course with BT, that's a big IF.

    Thanks TNP.

    Be interesting to find out what gives.
    Download speed isn't an issue as 20Mbps is ample. What I'd really like
    though is the "close to" 10Mbps up stream like wot I have at home to
    improve speed of my home<->work VPN as 1Mbps of ADSL2+ can get a little
    laggy using VNC.

  4. you should be so lucky. stuck on 5megs down 376k* up here, and it is
    pretty shity NFS mounting my (very) remote server over that.

    But I thought that FTTC was 100Mbps symmetric? or do BT in their
    Infinite-y stupidity go 16Mbps up?

    *what I actually get post packet header overhead.

    So far you are indeed correct, that, of course, doesn't mean that it will
    stay like that for ever

    No currently they don't, FTTC can only be provided to customers with
    cabinets. Last I heard they were looking at ways to provide it to
    directly connected customers.

    I'm directly connected but we are stuck on MAX from 20CN and I'm close
    enough to get 8128k sync. I'm not too worried about what BT do since
    I'm going to have to move so that HS2 can go through my lounge.

    IIRC it's 40/10 or 80/20. I get about 40/10 on the 80/20 version.

  8. @home I get 50/10 on the 80/20 I guess you gotta be real close to the
    box to get near the upper limit.

    www.GymRatZ.co.uk has brought this to us :
    I'm a BT cable jointer and also a union rep. for the Communication
    Workers Union. Our office is in the grounds of Telephone House and the
    Telephone Exchange and no, we can't get BT Infinity (or any other fibre
    product from anyone) because we're fed directly just like you are.

  10. Useful information. I did muse that the way BT works anything
    'different' no matter how technically simple and feasible 'just wouldn't

    For example ADLS repeateer fiully weatherproof and powered off the line
    voltage are cheap and would get broadband to many who simply can't get
    it now. But BT have never seen fit to deploy them.

    Well just where would they put them? Presumably they would need to be
    within 1km of the exchange to get 8128k sync. Then they would need
    another at 1km and don't forget they would probably need 60 of them for
    the village. Would they just dump them in the dyke and then the line
    voltage would drop after every set of repeaters.
    Rodney Pont, Aug 1, 2013
  12. they needn't target that. 1 @ 3km is about what it takes to take a 6km
    circuit from no go to 5Mbps
    No they wouldnt'. That' the pint MOST people are within range enough to
    get 2Mbps or better. Id like to see that as a MINIMUM standard for DSL.

    And a lot of people who are marginal are NOT in villages. They are on
    the outskirts of major towns. Or in isolated locations of 2-3 houses only.

    It becomes even more complicated when you look at some residential complexes
    where the PCP is in fact an internal room and the buildings have marginal
    DSL service.

    Got a couple of examples on my patch and no they can't/won't be getting NGA.

  14. Update: Just had the official answer for my line as follows:

    "Exchange Avonmouth
    Cabinet Direct E/O
    Tele No: 01179 823400

    Peter, yes you are correct your line is connected directly to the
    exchange (E/O), in the current phase of work we are not looking at fibre
    enabling E/O customers as they on the whole receive a much faster
    service at the moment compared to a lot of other customer fed by cabinets.

    In the next phase of work due to start 2014/5 we will be looking at ALL
    customers to upgrade to Superfast Broadband (90%) of the country.

    Regards Clive"

    So there we have it. No joy for the moment but hope is on the horizon so
    all is not lost.

    Cheers Pete@

    Watch it slip as they won't have covered most of the country (aka the 90%)
    which are being fed from PCPs let alone start on those who are fed directly
    (my exchange has slipped from 2012 all the way back to coming soon, over the
    last year) by 2015
