All I hear about is how a Phonecord and an ethernet cord have differet wire numbers. The last time I brought up a similiar plant i concocted it involved the USB Coder's Cable and dead drivers and ether converters.

How different are the BBAs from the 33/56k? Is it the dial up process? Could a disk be used to set a 56K up to behave like a BBA? A main issue for everyone is this:
I. 56K Dial up is a way of the past
II. Since no one uses dial up Cable/DSL is the only form of internet
III. Since we have phones the DC would keep it busy.
IV. Some games just want non DialUp.


This might not get you above 56k speeds but it might free your phoneline.

I want to add that

this thing.

that might be of help.

You know I always hate this many converters but togethor all are cheaer then a BBA. As for the Pipe-Hose situation I think it might be possible to get more ks then 56.

Dialup is still very prominent in certain areas of the United States and many other parts of the world (though nearly nonexistant in others still). But enough about that.

Dialup and broadband work on a very different system, and won't work that way, though both use the TCP/IP method for communicating when connected to the internet. What dialup mainly differs in is how it connects. It works on the assumption that there is a dial tone, and using different DTMF tones, one can reach a destination (ISP) and begin transferring data converted to audio over the phone line. It's an offshoot of the days of very old modems that actually worked with a real phone held up to a speaker. No communication will be made until the modem recognizes that it has connected to a remote machine accepting connections.

Ethernet (Broadband) works on the assumption that the connection is direct, and that any actual physical negotiation to the ISP is done by a different device (eg. cable modem, dsl modem, etc). It simply transmits electrical pulses over eight copper wires at a rate of upwards to 100mbps (Cat-5E). Newer Cat-7 cables can support over 10gbps, given that the devices connected by the cable also support it (otherwise, the lowest speed is used).

These both use different drivers to work properly, and thus a dialup modem will never be capable of connecting to broadband. Furthermore, the first device you've shown looks to me like a USB modem, which will definitely not support what you're trying to do (since it's a modem, itself), and the same goes for the ethernet device. This added to the fact that they both draw power from the USB bus, and thus won't be powered in the first place if used in this configuration. If it were possible to get these devices to work in the way you want them to work, the differences in the wiring layouts would mean you'd have a lot of issues with actually getting data to transport correctly.

In order to set a Dreamcast up to broadband without a BBA, you would need to connect it directly to a PC using a phone cable (assuming the PC has a modem). With a little fudging around (I haven't done it), you can make your PC listen for dialup connections, and once the Dreamcast makes the connection, you can use the broadband set up for that PC. This is much more complicated than it seems, and I've read that it takes a lot of trial and error to even get the Dreamcast to accept having no dialtone and just use the null modem. However, if you do get it working, you will still be limited to 56k speeds, since that is all that a standard modem (and traditional audio-based communications) can transmit/receive. I have no idea if this can be used to do development.

i kno about the PCDC connection. EVERYBODY knows. No 1 with a non 98/2000/me can get it to work. I tried this on my XP. The first device IS a phone jack. Its a phone jack to USB hook up for a laptop I guess.


Will this not at lowest work as a sorta primitive cable modem? What is it that tells the DC eventhough the end goes to the ethernet socket its not comming from a BBA? And i thought the ethernet cable itself going into the modem gave the line power. If the phoneline has copper in it too why cant it make some pulses? some weak ones?

No, it won't work, and no, that is not a phone jack, that is a modem; Otherwise, it would do absolutely nothing when plugged into a computer, and in fact would not even be detected by the computer.

Ethernet devices do not receive any power from being plugged into a line, and they must be powered, either by being a part of the computer itself, an expansion card, a router, or any other powered device, and the same goes for modems, though a certain amount of power does travel through the phone line.

The problem is that the DC can't even get out if it doesn't hear a dial tone and can't connect to the ISP. It expects to have to dial out; That's what it means to have a dial-up modem. The data that's transferred is translated to audio signals that go through the phone line - That's the static you hear when you're connected on dialup if you pick up the phone. Ethernet simply uses electronic signals passed down the copper lines; A standard modem's signal cannot be converted to the electronic signals put forth by ethernet without another modem to convert the audio data into such signals.

Therefore, no, you can not do it this way. There has to be a gateway device between the Dreamcast and the ethernet connection (a PC), and those USB devices simply won't work. To further add to the reasoning, USB devices expect to be plugged directly into a computer's (or any other USB-compatible host's) USB slot. USB devices contain on-board chips that allow them to communicate to the computer, identify themselves and tell it their capabilities. Most also require power to be fed through USB (there are rails assigned to this purpose) in order to operate properly (others have power plugs). If you plug two USB devices end-to-end like that, there is no chance of either communicating with each other. The reasons are twofold: First, they are not designed to communicate with each other, and second, they are not receiving any power. Even if one of them is plugged into a phone line, the power from that isn't enough to amply power even one of the devices, and thus it just won't happen.

So you see, even if you could get over the audio/electronics barrier between the two standards, your system still won't work. I'm sorry.

thats the site. that will show you the first converter is a phone jack.

if the USB cant communicate back to back why the hell do they make that adaptor?

and what if i add a volt simulator to the phone part? will that increase the power?

and the ethernet gets no power? how do you think i got this set up? if the modem itself want put thru power to the ethernet will not a hub?

and u claim the DC is listening for a dialtone but if that is the case how are BBAs possible period? is there no way to disable the dial up elements of the 56k modem?

you dont seem to understand how i have this set up.

You've obviously ignored all my attempts at explaination thus far, but bear with me.

First, the eBay auction *itself* says that it's a modem. I don't know why the guy says phone jack, but it's very much obviously a modem.

The adaptor you're looking at is for coupling two USB cables together; Plugging a USB device whose cable isn't long enough into another USB cable to make it longer. It will not allow two USB devices to communicate with each other. USB operates on the assumption that both devices will actively communicate, and is not simply a direct pass-through for information like an audio jack might be.

Another reason it won't work is because these components are not designed to draw power from the phone line, and no power comes from the ethernet line to boot. Any power coming from the phone line wouldn't be enough to run a modem by itself anyway.

The reason the Dreamcast can use a broadband adaptor is because there exists a special kind of software - Called firmware - that are inside the modem and broadband adaptor. They contain instructions which are passed on to the Dreamcast as to how the hardware can be used. When a modem is connected, the modem tells the Dreamcast "OK, I'm listening for a dial tone - There it is, I'm dialing. Waiting for a response... OK, I'm connected, I'm negotiating... OK, we're on the internet". When a Broadband Adapter is connected, it tells the Dreamcast "OK, there's a network cable connected. I'm getting an IP address... OK, we're on the internet." Using a modem, you cannot physically transmit information to an ethernet cable no matter what you do.

Again, a modem translates data into audio information. This cannot be translated back into data (eg. Ethernet) without being connected to another modem first (eg. PC).

If you still want to try it, that's no difference to me, but don't say you weren't warned. Just because everything plugs into each other doesn't mean you'll automagically get it all to work.

So again, no, this does not equal a BBA, or even an internet connection at all.
