TELECOM Digest is an electronic journal devoted mostly but not
exclusively to telecommunications topics. It is circulated anywhere
there is email, in addition to various telecom forums on a variety of
networks such as Compuserve and America On Line, and other forums.
It is also gatewayed to Usenet where it appears as the moderated 
newsgroup 'comp.dcom.telecom'.

You assume that the Government is monolithic. It's not, and Congress is often at odds with the executive agencies that seek to enforce the laws that Congress botches up ^H^H^H^H^H^H^H^H^H writes. Mitnick may not need publicity among the cognizenti (I guess that's us), but his career as a black-hat hacker is probably over. He's now repositioning himself as a "security consultant," quite possibly to the CIS departments of the same government agencies and private companies (such as the New York Times) that tried so hard to put him in jail. Moreover, he can do this without ever actually *touching* a computer. (He may be high-paid enough to do what little actual computer work he must do by dictating to a typist, as Dick Stallman did when he had carpel tunnel syndrome.) Indeed, as reported in this story, Mitnick got the endorsement of his persecutor: [sic] > Los Angeles Assistant U.S. Attorney Chris Painter, who won the

That is surely good for Mitnick's future security business, giving lectures on "human engineering." Kevin Mitnick knows *exactly* what he's doing, and he's playing those Senators (and prosecutors) like a violin.

Last time I checked, Congress had no power to overturn a court order, and judgments are court orders, or to pass bills ex-post facto (after the fact) or to pass bills of attainder (affecting one person.) John Willkie [TELECOM Digest Editor's Note: They certainly can pass bills which affect one person, although it is not done a lot. I think at the very least, they might have held a hearing a year or two ago, placed Janet Reno and a couple of her head honchos on a hot seat and asked her, 'Just why is Kevin Mitnick, a national hero in the estimation of many in this country being held in prison unconstitutionally without any trial for four years?' When they finally got around to letting him out of prison, he should have been allowed to walk freely, without any restrictions whatsoever on his speech or actions. They could have done a lot for him, but chose not to. PAT]
From: Linda Harris <tamworth@voicenet.com> Subject: Re: Communication Tower Date: Sun, 05 Mar 2000 01:53:34 GMT First of all, thank you to everyone that has responded to our query. I will e-mail all concerned ASAP. We are a farm, southwest of Pittsburgh PA, with an elevation Bench Marker on our property of 1320ft above sea level. The site for the Tower is even higher than the Marker. From the intended site, you can see for a radius of over 30 miles. Saying this, it does not affect any property apart from our own. We have road access already in place, telephone cable and electricity. The site is a perfect spot for the erection of a tower. The tower company is offering us $5,000 per annum, with a 15% increase every 5 years. The lease will run for 55 years. We feel that because we are farmers, and the way farming has declined over the last few years, the tower company is taking advantage, thinking that we will snap up their offer. Obviously they want to get the site for the best possible price, we on the other hand feel that we should try and negotiate to get a fair and more reasonable offer. After all this will affect the next generation on the farm and possibly the one after that. We have read and re read all the e-mails that we have received, and will reply to them all, within the next day or so. Please e-mail me if you have anything more to say since receiving more details. Yours Faithfully, Linda Harris

I've seen such code used in both e-mail spam and newsgroup postings, and Netscape Communicator automatically executes it upon viewing the message. (Communicator has settings to turn off Java and JavaScript in messages, but not HTML. The only reliable way to avoid connecting to the web site in such cases is to download your messages, unplug your PC from the network, then read the messages.) I have complained to Netscape, was brushed off, and even wrote the problem up in comp.risks. I don't know if MSIE or other Internet software has the same vulnerability. Combine this with a malicious web page, and it will give the lie to the old saw that you can't get a computer virus merely by reading a message. Maybe after this happens and hurts enough people, Netscape will do something. John David Galt

It seems that there are two issues concerning the use of subscriber loop carrier arrangements: v.90 modems and xDSL capabilities. I more or less agree with Bill Horne concerning xDSL -- you just can't make copper pairs appear out of nowhere. The incumbent telco is not in the business building copper plant anymore (unless, of course, the incumbent telco sees xDSL as a line of business it wants to be in.) But the v.90 modem problems are just plain lazy engineering even if not a conspiracy. (or maybe a little bit of both) There have been discussions about DLC in this forum on several occassions. If properly implemented, it shouldn't matter where the analog-to-digital conversion happens: at the CO or in a vault near the subcribers' homes. As I understand the issue from past discussions here, the problems arise when these digital carrier arrangements are improperly configured -- or when somebody uses them at *both* ends, converting back to analog before presenting the loop to the CO switch. If the ILEC wanted to accommodate v.90 modem traffic (and those nasty long duration calls which internet junkies and VPN-using telecommmuters make), the very well could. The thing that amazes me most, however, is the difficulty that the ILECs seem to have in understanding that CLECs are not going to go away and that if they stopped digging in their heels they could make their wholesale business very profitable indeed. If the 'carrier hotels' that are spring up can make money renting space to various service providers, why aren't the ILEC's building or leasing vault space in subdivisions or city blocks where they can terminate short subscriber copper loops and lease rack space and fiber backhaul to wherever. Nobody's going to build competing last mile facilities if the ILECs maintain their advanatage as efficient producers and progressive stewards of that portion of their plant. Somehow, however, I think that the ILECs are so focused on long distance services -- ironically an increasingly competitive market with decreasing margins and under the sword of Damocles caleld internet telephony -- that they cannot figure out the long-term profit opportunities imbedded in their local plant, engineering expertise, relationships with local government, and remaining craft workers.
From: Joe Machado <jmachado@webzone.net> Subject: Give me Some of That New Wireless, Maybe Date: Sun, 5 Mar 2000 00:15:43 -0600 It may have started with Eniac, the big beast that would perform calculations quicker than a human could, supposedly. Soon, the need arose for more computing power and a smaller footprint. IBM and folks provided the solutions but still more power and a smaller footprint was needed, especially one where people could easily use the beast. Gates and Jobs provided the footprint and solution, later Compaq and IBM, and soon we were computing on the desktop as well as the data center. My old Kaypro 10, with its CPM operating system could perhaps be considered an early form of mobile computing; just latch the keyboard on and take the whole thing to another location. Wonderful stuff! Laptops later came and got better screens, video, and power. Now we could really compute anywhere! The trend continued and motherboards got smaller as did 'mainframes', while also gaining in computing power. These communication resources were not sufficient, we also needed to speak to one another no matter where we were. Portable phones provided the answer ( no pun intended ) and it looks as if just about everyone in modern civilization today has a cell phone. However, if you could speak using a cellular telephone, and surf using the laptop, why not have the information one gets while surfing on the telephone? Sure, there was the matter of different screen sizes and amount of content, but WAP fixed all that. Now, you can speak on the cell phone, surf the net, receive and send emails and messages, and more, all on the same unit, the cellular telephone. You can also speak through your computer with someone else far away, and for free ... oh no! That is just free stuff, not WAP ). Wonderful opportunities, very interesting, and great fun!!! Excuse me, but is miniaturization going on? Yes, the world is shrinking due to the convergence of technologies and the accessibility we realize by using them, but, is not the technology also shrinking? It seems that what we are trying to do is exert ourselves into the many possibilities available not just as we knew them with a telephone and a computer, but also our realizations due to maturation of the Web with our participation in it, and all by using one single device. ( BTW, where is my cellular Cisco Pix on a chip? Also, can other people hear and see what I am doing? And, am I frying my brain or ear drum with this new gizmo? ). All the things we can do with multiple devices we can now do ( just about ) with one small handheld unit that can fit in a pocket on our clothes. This technology is cool, interesting, useful, and at many times necessary. It is also affordable for many. The technology really works and virtually anywhere, thanks to the big boys, including the Satellite folks! Hopefully everyone will be able to partake of these many options. My question is when are we going to stop using screens? Instead of screens an image could be projected using Red, Green, and Blue from a transmitter in glasses, or from a pendant, or from a wristwatch, or some other such device that does not use a screen to deliver the content. We could also use holographic projections and project the image into 3d space, again, in color. Why can't we look at a web page projected in front of us in space in a size that is relevant, complete with sound and all the content? Why can't we enter a web site and move around in it? Going to the grocery store ahem...) might really be fun, especially if other people were also in the site at the same time. Why can't we see the scene or image and engage in 3d communication with others from a chip planted in our brain? Why can't we think and realize the intent? Will we have to discuss the collective unconscious and how to not just materialize it but also use it? Do we need a chip in our brain? Would I not prefer being in my own home with my family instead of with the world in 3d virtual space? So how do we do a holographic projection that can fill a room? What kind of power source would be required for a set of glasses to deliver a 2 foot by 2 foot image in front of our faces? What technology would be required? Interesting issues and they are pressing. I think some grandchildren today will provide the answers, hopefully sooner than we are ready for them to. The way they would relate with each other would still be as we know it today, an age thing, but their communication would be more meaningful, complete, sharing, and indeed diverse, as well as dimensional. Why? Because they have bridged time and space and now share the world through common experiences ( can the new Cisco PIX prevent my daughter from being with that guy? ). Hopefully they would not forget us, but we are history moving forward. In the meantime, why can't we work at projecting a web page or a NetMeeting type interaction inside a car windshield instead of the speedometer?

From: Steve Hayes <stevehayes@compuserve.com> Subject: Re: An Electronic Spy Scare Is Alarming Europe Date: Sun, 5 Mar 2000 12:15:57 +0000 Hi Pat and everyone, In TELECOM Digest V20 issue 4, Monty Solomon forwarded an article by Suzanne Daley about concerns with potential commercial espionage via the Echelon network. This network is run by the U.S. with various English speaking allies including Britain and intercepts all sorts of telephone, fax and e-mail traffic. Supposedly the network is used to gather intelligence about terrorists and drug traffickers (and, when it was dreamt up, about our Cold War adversaries of course). However, it is obvious to anyone that it can also intercept commercially sensitive information and this is what most concerned the French government when it kicked off the furor. In V20 issue 5, W.D.A. Geary pointed out that it is a bit rich of the French to complain about this in view of their long record of commercial espionage. This is quite true but the U.S. has an equally sordid record and I'm sure that Britain wouldn't fare any better if the facts were all known. If someone warns you not to leave your front door unlocked, you should listen even more carefully if you know that they are a burglar -- after all who would know more about the dangers. There is a story about the well known novelist and politician Jeffrey Archer which non-British readers may not have heard. Some years ago, a friend of Archer made a nice profit on some Anglia TV shares which he bought (or did Archer buy them in his name?) just before a takeover bid was announced. Archer's wife was a director of Anglia TV and the authorities suspected insider trading. Even if Mrs. Archer had kept quiet about the bid, she had been sent faxes about it which must have been hanging out of the Archers' fax machine until she collected them. Even in a case like that, the authorities could not prove anything and the case was dropped. Archer has since come unstuck over a completely unrelated scandal from his past. The point is that if even a case like this is inconclusive, what are the chances of detection - let alone prosecution - if similar information was leaked after it was intercepted by a network like Echelon. The spying agencies (especially the CIA) have long records of partnership with criminals (e.g. drug traffickers) where they could further the agencies' other goals. On top of that, information is passed to politicians who are rarely adverse to a bit of "you scratch my back and I'll scratch yours" (see the current French Elf Oil scandals). Then of course, low level personnel in the agencies may seize their own opportunities. As an old cynic, I suspect that it's private gain rather than the desire to catch terrorists which explains the willingness of governments to fund systems like Echelon. The French have now warned their European partners and companies as well as everyone else that no e-mail, phone call or fax is safe from prying eyes (unless strong encryption is used). I don't think we need be paranoid about the insignificant details of our everyday lives but no-one should send unprotected information which would be worthy of exploitation by someone else. I think that the French have done us all a great service and only wish that my country was not being used so blatantly as part of this network. Steve Hayes South Wales, U.K.

The point of pain would at least be on the person who decided to make that call. Cellular Caller ID would help, but I carry a cell phone so that certain people can always reach me. I don't want to pay for calls from just anyone, so my number remains private. And the cell company loses business because those calls are never made. I believe that caller pays would lead to an increase of cell phone usage, sharing the infrastructure costs out over more minutes of actual use, and lowering the overall rate paid per minute to the point where calling a cell would cost the calling party a reasonable rate. I would be willing to give out that number more (since I don't have to pay for it) and, just as it is in caller party pays countries, usage goes up. > There is little restraint to imposing fees on non-customers.

If I use a 'foreign ATM' I am in a sense a customer of that institution. They pay to maintain the location, stock the machine, and network to the national system. I realize that they would spend that money for their own customers only, to a certain extent, but there is cost involved, and some banks have chosen to charge fees instead of eating them. (I also get to pay to talk to a teller at my bank, where I AM a customer. Fees are getting out of hand.) Foreign ATM fees have been around for years, and I dispute your claim that 'most ATMs' were deployed before fees. Too many "ATM Inside" gas station and mall locations popping up over the past few years. I'd like to see some real numbers from the US on the Caller Pays issue. Cincinatti would be a good place to start as they have had a mix of caller pays and cellphone pays prefixes for many years. The foreign trends look good, but it would be nice to see NANP numbers. JL

San Francisco, and many California communities, have been working to place overhead wiring underground for several decades. One serious drawback to overhead wires is that they tend to suffer damage in large earthquakes when the spacing between the tops of the poles oscillates wildly. Obviously, maintaining emergency communications is a issue. But even more is the risk imposed by fallen power lines and poles which can and do become debris blocking streets and preventing access by emergency vehicles. Poles don't go away after an undergrounding project, however. They are still needed in some form to support street lights and traffic signals. However, by not being yoked together at the top, these posts can be designed to vibrate like a diving board stood on end. As for the locals "killing themselves when digging fence post holes," I'd be surprised if the number of such incidents is even significant compared with the number of people who drive into utility poles or are injured when someone else shears off a power pole and it falls onto someone or something.
