    Default DSL modem recommendation

    Hello,

    Could anybody recommend a good, solid DSL modem that is supported nicely
    by FreeBSD? An internal modem would be preferred but I would consider
    otherwise. My main requirements are stability and a lack of any kind of
    external management (I want my box to be solely in control, not a
    proprietary web or telnet interface).

    I have suffered for far too long with an awful DSL router/firewall that
    goes down at the slightest provocation and offers no real
    authentication!

    Cheers,
    Mark

    Default RE: DSL modem recommendation

    What is your DSL provider, what telephone company are they using?
    Are you running bridged or ppp mode DSL?

    DSL modems all use proprietary implementations of the DMT protocol,
    while many will interoperate with different DSL providers and
    DSLAMS, not all will.

    Hi Ted, the relevant info:

    ISP: Pipex UK - [url]www.pipex.net[/url]
    TelCo: British Telecom

    I am currently connecting to them via PPPoA (I assume this is what
    you're referring to, I'm not as knowledgeable as I'd like to be about
    DSL).

    Cheers,
    Mark

    Hi Mark,

    OK, pipex is one of those ISP's that doesen't give support to
    non-customers
    so your going to have to do a bit of legwork for me.

    First, are we talking PIPEX Xtreme Solo, or PIPEX Xtreme Business?

    Next, log into the Pipex support site for the appropriate service you
    have:

    [url]https://www.mypipex.net/solo/[/url] or [url]https://www.mypipex.net/solo/[/url]

    and go to the support section on DSL modems. Let me know what the
    DSL modem models are that are listed as supported.

    If there isn't a listing there, then go to the online ordering
    [url]https://secure.pipex.net/cgi-bin/products/xtreme/modem-mf-order.pl[/url]
    and make an order like you are ordering another modem, go almost
    all the way through then abort the order, and in the middle of the
    order it should give you a selection of modems that are available
    from them for ordering.

    Lastly, if you get nothing either of those methods, CALL them at
    0845 077 2455 / (0845 077 BILL) and ask for tech support and
    ask for a list of supported modems. ALSO, very important, if you
    do call them ask what the VPI/VCI the modem is supposted to be
    set at. Usually 1/1, or 0/32, or 0/35, those are commonly used
    ones. If you have administrative access to the modem you have
    now, it should show this. Also ask them if it's regular DMT
    issue or G.Lite DMT? Adminstrative access to the modem you have
    now should also tell this.

    Also, please post the modem model that you are currently using
    now (the piece of junk one that isn't working well)

    I need to get an idea of the DSL modem chipsets they have their
    service setup for.

    Default RE: DSL modem recommendation

    Hi Mark,

    Well, looks like I was able to bypass that login thingie, here's
    the info:

    Settings:

    [url]http://www.pipexsupport.com/main/pipex.php[/url]

    Modems:

    [url]http://www.pipexsupport.com/main/hardware/[/url]
    >From the looks of it, they are using standard DMT issue, not G.Lite,
    with the Alcatel chipset, VPI/VCI 0/38

    This is a really good universal combination. Many DSL modems will
    work fine. But there's 1 modem that I would strongly recommend
    in this instance over any other modem:

    Westell C90-36R516-01

    Why? Here's why:

    1) These are dumb bridged modems so they aren't interfereing with
    your BSD box.

    2) Westell has updated firmware and a diagnostic utility that
    talks to the modem, and has a secret command key sequence that
    will tell all of the good line stats (signal to noise ratio,
    received and transmitted power, etc.) which are vital to
    troubleshooting.

    3) Since these modems were obsoleted and were used by Bell Atlantic,
    there are tons of them on the used market for very cheap.

    4) Other ISP's I've talked to have said these things are rock
    solid reliable. I have never had one of them fail in service
    for any of our customers either.

    5) It has an honest-to-god Alcatel DSL chipset in it, not the
    globespan which is becoming more popular (primariarly because
    it's cheaper)

    Now, note the following: if you have a very spotty DSL line, then
    get the following:

    Westell B90-36R515

    NOT the B90-36R515-01!!!

    Why? Because the 36R515 has a design flaw in it- it massively
    overexceeds the transmitted power allowable for DSL - this is
    why Bell Atlantic quickly switched over to the -01 model - that
    will sometimes allow you to punch though a crummy line and
    get a stable connection. But the downside is it's DSP microcode
    is non-upgradable. You don't want to use it unless you have to.

    Now because this is NOT a PPPoA modem, you must run PPP on your
    FreeBSD box. The big advantage is that since your FreeBSD box
    is the PPP terminator - not the DSL modem/router - you get a
    legal public number on the ppp interface in the BSD box, which
    means if you want to set it up as a server your in business.

    The only possible problem is that these Westells were sold
    only in the US, they take 24 volt AC (NOT DC!) and come with a 24 volt
    AC adapter. But, you can just go to any junk store and buy
    a 24 volt UK style AC adapter and cut off the useless US-style
    adapter from it's cord and solder the cord onto your adapter.
    (or use a voltage converter from 220-to-110) The adapter is
    NOT AUTOSENSING so don't attempt to just plug into UK power
    or you will blow the modem up.

    The modem isn't particular about 50-60 hertz so no worries
    there. I also don't think you would have a problem with
    the UK/US phone line voltage difference either.

    You also will need to change the VPI/VCI setting to 0/38 it
    is normally 0/35, westell has a utility for that.

    If you are a bit sqeamish about this, then looking at the PIPEX
    recommendation page, go for a ZyXEL Prestige 630

    STAY AWAY from ANY dsl modem that does NOT have an ethernet
    jack on it!!! Such as the USB speedtouches that Pipex
    was handing out for free!! There's a reason they are free!!
    You can't pay people (who know anything) to take them!!!

    Thanks for the recommendations and the detailed info! I will
    probably give both a try and I definitely not be touching those
    sorry USB things (I've recently been trying to get one up and
    running on my friends BSD box and have pretty much given up
    in disgust).

    I'll be trawling eBay within the hour. :)

    Thanks again,
    Mark

    What is so wrong with USB DSL modems? I have an Alcatel Speedtouch
    modem that has been absolutely rock solid since I bought it on ebay for
    £8.50. It was very easy to setup. I just installed the pppoa port and
    set up the ppp.conf file and plugged it in. Takes about 30secs to
    1minute to start-up on a boot but once it is running I have no problems
    at all. Using it for my home server and I route all of my home network
    traffic out through it. No problems at all.

    The USB port was designed for use with joysticks, keyboards,
    mice, etc. Not ethernet speeds.

    If you ever have an opportunity to do a side-by-side comparison
    between an ethernet modem and a USB you will see your CPU
    utilization much lower on the ethernet. Ethernet controllers
    are far superior and efficient than USB chipsets.

    Now of course, DSL is not high bandwidth (compared to Ethernet)
    so there is that argument that it makes no difference.

    Another argument is that if you have no need to run a server,
    USB means you have to waste CPU on translation. Of course the
    counter to that is that with a modem/router, you can't get a
    public IP address.

    And yet another is that if the hardware changes in the future,
    a day might come when a new motherboard with a new USB chipset
    is not detected and usable by some version of FreeBSD. Ethernet
    your pretty much guarenteed will be around forever.

    But, speaking as an ISP I can tell you the biggest reason
    we recommend against USB for our customers - most of our
    customers are windoze users, and if you put a USB modem on
    their windows boxes, when they connect in, they get a public
    IP address assigned to their Windows box.

    And if they aren't currently patched (few 'doze user are ever)
    within an hour their machine will be compromized by someone's
    trojan and their machine will then become a menace and a problem
    on the network. Our network.

    We do not see the advantage to us to have a couple dozen
    'doze users on our 1.5x1M DSL circuits, infected with the
    latest virus and attempting to reinfect the rest of the
    Internet. Maybe you do? Certainly the cable Internet providers
    in the US seem to think there's an advantage, that is why
    the cable networks all run like dog crap.

    I was just thinking that. :)

    I guess generally most would not require to run a server so thats a fair
    point.

    Why would I buy a computer with a motherboard not supported by FreeBSD?
    I guess if we are speaking about the general user that may apply but
    you could also argue the general user would most likely be using windows
    and pretty much guaranteed a working proprietary driver. Of course by
    the time this new chipset is out, Windows may be dead and FreeBSD is the
    new ruler of the free world. You just never know. ;)

    Yeah, I can understand why that might be a problem.

    You come across as being a very smart guy so why ask this question? I
    am asking a general "why not USB?", not "USB modems are awesome and you
    should all convert!".

    I know.. This is a google question... But anyone know the speed of
    USB???

    I am considering modifying our wireless modem pcmcia to usb instead...

    Of course you can get a public IP address. The standard ADSL equipment
    here (Denmark) is a Siemens modem. You connect the modem to your
    computer over Ethernet, and get a public IP using DHCP...

    Sorry. I'm just ranting. USB ethernet is an abomination and I cannot
    forgive the morons in the industry that did away with RS232 serial
    ports in favor of USB. Espically since I have tons of equipment I
    service that have serial ports on them. Ever have the pleasure of
    working with one of those USB-to-serial port adapter POSs?

    Seriously, if what the PC industry had done was when USB came out, just
    completely did away with the keyboard port and the PS/2 mouse port, and
    tied those interrupts to the USB controller, so that the new PC
    motherboards
    required USB mice and keyboards, then I would not be so disgusted with
    it. Instead, they just layered it into the PC architecture. I have
    PCs here that when you put 2 nics in them, you lose one of the on-board
    serial ports, and this is without even a sound chip in the system.

    Only if the Siemens modem is in bridged mode, and most DSL providers
    ship these devices in routed mode, not in bridged mode. If Network
    Address
    Translation (NAT) is turned on, which it is by default when these devices
    are in routed mode, then the IP address you get is a private address
    handed out
    by the Siemens modem, something like a 192.168.1.x number.
