How can BT tell the # of actual users? Also service levels?

    BT offer a "single PC" BB package. I spoke to them yesterday and they
    say they have software to detect multiple users. I asked how can they
    tell, given that they even give people a NAT router which conceals all
    stuff behind it? They said they can still tell, and kick people off.

    I suppose they could detect usage which is unlikely to come from a
    single *human* user, e.g. concurrent HTTP sessions. But they could
    come from a piece of software.... like a www browser!! Perhaps
    concurrent POP sessions?

    So, how can they tell?

    I am after two fixed IPs, and no restriction on the # of PCs. In
    reality, it will be very light usage, although we will be running a
    www and email server on the end of it.

    The other thing is whether going to BT for BB is likely to get a
    better service than using another BB ISP.

    AFAIK, the only physical presence of another ISP is that ISP's
    building, plus a fibre connection from them to BT. After that,
    everything is over the BT network anyway. And given that the ISP will
    have a very big incentive to keep their fibre to BT going at all
    costs, I don't see how *BT* BB will be less likely to fail than
    somebody else's BB.

    I have to buy an analog line anyway (have 4xISDN at present which we
    need for other stuff) and for £3/qtr I can get a 4hr response time
    from BT on the analog line (only). Nobody will offer any response
    level on BB, it seems, so what is the chance of BB failing but the
    underlying analog line still working?

    The ISPs I am looking at are Clara (currently use them with a 64k
    dial-up and they are generally up OK, if unresponsive to customer
    service issues) and Onyx (who I have used for about 10 years for www

    Any comments would be appreciated.

  2. Sequence numbering on the packets is one indication. While it's not
    going to be 100% conclusive it will (especially if Windows is the OS
    in use) be indicative of more than one TCP/IP stack in use. ie there's
    more than one machine behind the NAT.

    Why they should give a damn is another matter entirely.

    PlusNet will offer two static IPs as part of their unrestricted BB
    packages. I don't know about other providers.
    No. The general consensus appears to be that there are better ISPs
    around. Check out for details.
    ADSL gets you from your premises to the ISP. After that there's the
    ISP's equipment (routers, proxies, caches, mail servers, and whatnot),
    and after that there's the connection to "The Internet" (whatever you
    like to define that as).
    Ah. BT Broadband is not BT Openworld is not
    BT-the-ADSL-transport-layer-provider. Honest.
    Yes, that's right (except *possibly* Andrews & Arnold), as the ADSL
    layer is not under the direct control of any single ISP (including BT).
    Surely that's a problem when you have an issue? I'm generally very happy
    with PlusNet (I've been with them just about a year for BB; before that I
    used Demon, Freeserve, and UKU for analogue dialup), and would be happy
    to recommend them to you.

    Surely, ADSL is just the data encoding method used on the local loop.
    From the local exchange, all the way back through BT's network, it is
    ATM, 155mbits/sec. A neighbouring business has just got 2mbit/sec DSL
    put in - cost them a fortune but it is just a different box at the
    local exchange. I don't think the ISP knows any different.

    Yes, the ISP can fall over but they have a big incentive to get back
    up. Whereas if I get a problem between (or in) the local exchange and
    my premises, absolutely nobody will fix it unless I complain and it
    will have to be BT doing the work because all the equipment is BT's.

    There are options using other equipment than BT's network. Certainly
    not available nationwide, but Easynet and Bulldog have their own kit
    in some exchanges. Anyway, the general advice is that you will find
    better deals looking around... There have also been comments which
    are positive about BT's services (under their several brandings, in
    that you can get BT Broadband or BT Yahoo! Broadband depending on
    what you are after. I don't remember seeing either listed in the
    'top 10' at but maybe I just didn't spot the month(s)
    where they managed it. Speed isn't everything, of course, and you
    might want a fixed IP address or to use some other facilities which
    another ISP offers... Down to you to choose. Good luck with BT !!

    Yes. From your questions I figured it was better to simplify that part
    of the description, though, and call the entire DSL/ATM bit "ADSL".
