    (off on a tangent) I recall many years (1970s?) ago how they did (and maybe still do) broadcasts in Boston of Boston Symphony concerts at TangleWood in the Berkshires, over 100 mile away. They had recordings of the original source, they had the signal at the end of the phone line, and they knew what the difference was. They merely amplified the signal at the source end to compensate for the losses, making sure to not clip the signals. Result at the end in Boston was a signal completely acceptable for FM Stereo broadcasts.

    So I can see if you are not completely expert in the technology, being able to make up your own examples, and talking yourself into believing that Certain Limitations had been exceeded.

Since you telephone signal goes into a 64 kbps digital channel there, you cannot get any more than 64 kbps out of the analog end. DSL requires the telco to install new hardware that splits the high frequency and low freqency components, sends one to the phone connection and one to the DSL hardware.

      Even so, noise, loss, and crosstalk are all problems for DSL causing it to be limited range, especially for the high bandwidth versions. In addition, equipment installed to prevent ground loops and improve the quality of audio freqnecy transmission, especially in older or long distance phone runs wasn't designed to pass high frequency and can wreak havoc on DSL. None of these problems have to do with the wire itself, though. Copper has plenty of bandwidth, the purpose of coax and so forth is to decrease losses and interference.

If they say it doesn't work and it does, they get sued by the inventor. So, what do they do? They hedge their bets. They say that "more study" is needed, etc. To business types, this sounds like they are just being nerdy and cautious.

Most never got in, but every now and then one would. As a fairly visible, and known very cynical, engineer, I often was invited to meetings with these types to try to flesh out if they were full of it, or had something interesting.

BUT, we (as well as every other modem mfg) shipped a free driver along with our modem that fixed that problem. MS also fixed the problem in Win98. When I showed them the same type of t-put on another PC in our lab, with the updated driver, their faces dropped, they shook in disbelief that some other genious had discovered this before them. I escorted them out of the building. As a parting gift I gave them a copy of the driver we used, and told them my shortcut back to the airport and recommended a bar on the way.

Though not entirely incorrect, the goofy phone network did pose some serious challenges (particularly in US, Canada and Korea), and it took a couple years to really refine it.

    The Rutherford Appleton Lab's VULCAN X-ray Laser here in the UK gets down to about 5.9nm, though it's apparently huge (providing 90J of energy IIRC) whereas the CMT ('Comet') is obviously compact but only produces 5 or 6J of energy.

    That's probably out of date by now but the point stands...

    However -- 56k depends on one end of the connection being DIGITAL . You're eliminating quant error on one side of the connection, thus you can get better downstream speeds. Upstream speeds, if you notice, are still limited to 33.6k due to quant error on the end user's modem.

      Technically, you are quite correct, I will not argue with you on that fact from a technical perspective. From a perception perspective, he did indeed. Most folks thought, based on Shannon's statements, that we were done and could not squeeze any more data through using a voice channel. So, in many ways, he really did.

      Hmmm, tell that to the folks using V.92 modems with upstream PCM that claim up to 45K upstream. I have not been involved with them, so can't give you any figures, but I do know that it works for some percentage of the population. From what I understand, quantization is the issue that is keeping it down to 45K, but acquiring timing was the main issue preventing PCM modulation from working in the upstream (A to D) direction. That has now been broken as they figured how to do timing. Yes, this still requires digital on one end, plus I suspect not too many ISPs have installed gear to service it.

      Is this technically breaking Shannon's Law? I am not sure enough to make the bold statement that it is.

      Nope, it's not breaking the Shannon limit, because nothing can break it. It's impossible. So if somebody does manage exceed the "Shannon limit" on some channel, it can only be because it was incorrectly calculated.

      The Shannon capacity in bits/sec of a noisy, band-limited channel is C = B*log2(1+SNR).

      So to compute the Shannon limit, you need to know both the bandwidth and the signal-to-noise ratio of the channel. Both numbers can vary quite a bit for plain copper pairs. The signal-to-noise ratio is affected by things like attenuation, crosstalk from other pairs and transmit power limitations to avoid crosstalk to other pairs. And bandwidth is affected by the length of the cable, its insulation and wire gauge, the presence of loading coils, etc.

      That's why DSL speeds vary so much from one place to another, and why it's no big deal to send at much faster rates than DSL over short (a few hundred meters max) twisted pairs that have been carefully constructed (i.e., Cat 5 cable).

Now Cisco is a big, reputable company, not some small time con artist and we are friends with the engineer in this city. Doesn't matter, we STILL wanted to test it for ourselves. So they sent us an LRE switch and two remote units. We tested it, and indeed it does perform as advertised.

    Now we know for a fact that it works. This wasn't a smoke and mirrorrs test, it was conducted in our lab, by our people. They weren't even around (the just loaned it to us for a month and said have fun). We got to run all the tests we chose on it. All this, for a product from a reputable company. But you know what? That's how you need to do it. Don't rely on what the people who make something tell you, demand to test it yourself. See if it works as advertised in YOUR environment.

    This is doubly true for new technologies. Make the inventor bring his tech to your labs, demo it on your terms, and have your people run the tests.

    Yup, a hair under 10% is a very large number of people. Sorry to hear you are a part of that large minority. Unless you know for a fact you have an additional A/D in the path, be sure to check you have the latest code. There were some significant improvements made to the code, post V.90, that got a whole lot more people working with V.90. A good sign that you have the latest code is if you get 3 "bongs" at the end of the training sequence. Note: not all models had new code built for them. Also note: the third "bong" only kicks in during certain conditions (the modem "thinks" there is a chance it might work). These fixes were to deal with situations like a long local loop (often rural lines) that caused the signal to appear to have encountered an additional A/D when in fact it did not. YMMV.

  36. I saw a demo from these guys... by Anonymous Coward · · Score: 5, Informative
    I don't remember the exact year, probably like 1996 or so. I was working as an engineer for xxxxx. One of our VPs asked me to go with him to Jacksonville to see a demo of a device which could transport a DS-3 over a dialup line.

    In the demo, however, they were just going to do a DS-1. I took a t-berd DS-1 test set, a Navtel protocol analyzer, and some cables, including a DS-1 loopback plug (RJ-48). We met them at some hospital in Jacksonville, present were Madison Priest and Mark Strong. Mark video taped the whole thing, which made me kind of nervous.

    They took us down to the communications room in the basement of the hospital. There were two Packard Bell computers sitting on the floor. They were both plugged into the same powerstrip. The interesting part was there was not one power cable, but three for each computer. I think two of them ran into one of the ISA slot openings, and were "expoxied" in by what looked like latex caulking. It was a real mess.

    Each computer also had an RJ-45 for the T-1, and an internal analog modem. I plugged the t-1 test set into one computer, and a loopback plug into the other. Madison then used hyperterm or procom (I forget which) to dial from one computer to the other thru the Hospital's PBX. When the modems synced up, the T1 came up. I verified I was seeing the loopback, sent some different bit patterns, and errors. When he pulled the pots line, the T1 went down (loss of signal).

    Next, they wanted to show it ran over long distances. They used one computer to dial a number in my office in xxxx which was forwarded to the number of the other computer next to us. This worked just as expected. The T-1 came right up. We let the test set run awhile to make sure the line was error free. Mark Strong made it a point to videotape him asking me if it was working. About all I could say was that "It appears to be."

    We went to a conference room nearby to talk while the test ran. Madison was pretty strange. He got, what I would term, angry several times during the meeting. I stayed out of it pretty much till at what point our VP asked me what else I needed to verify to make sure that it was capable of carry a T-1. I said I wanted to put the protocol analyzer on the circuit and make a call through xxxx. Then I wanted to send frames and measure the latency of the circuit. I said I know about how much latency I should see, given that signals travel about 100 miles per millisecond.

    Then all hell broke loose. They refused to allow that test, or any others. They claimed I was trying to steal their technology. We ended up packing up and going home.

    Over the next several months, we heard from them about doing more tests. We wanted to do a long distance video feed, but the week that was supposed to happen, weather was not good (I think it was too icy) for their general aviation plane to make it. They started calling themselves VisionTek, and they informed us, of all things, that we wouldn't see the latency we expected because this thing could transfer a signal faster than the speed of light.

    I had suspected the power cords were the actual data path, and my latency test was going to test that theory, but they never allowed it to happen. I don't think they had come up with the "faster than light" story by that time, so I believe we caught them with their pants down.

    I don't think we ever invested any money in them. I always believed it to be a hoax, but was just doing my job to investiagate it. I also knew that Madison Priest was an ex-con, and after witnessing his temper, I didn't want to become any more involved than I had to. I certainly wasn't going to challenge him or do anything that would lead him to believe that I *personally* was the reason he didn't get money from my company.
