After an initial series of overview chapters, the details are covered by specialists in the various fields. Most such works can vary a great deal in both content and quality. This text, however, maintains a consistent standard of both information and readability throughout. After a discussion of "open"ness and distributed systems, there is an introduction to the concepts of modularity, communication and concurrency, as well as a look at real time systems and reliability. Then comes coverage of security, formal methods, communications support, CORBA (the Common Object Request Broker Architecture), multimedia, network management, distributed file systems and load balancing issues. There is a final look at future trends and challenges. copyright Robert M. Slade, 1996 BKOPDSSY.RVW 960403. Distribution permitted in TELECOM Digest and associated publications.

That was what they said; I had a PCP account back then and in reality what happened was that people were using it for business, most of the time, multiplexed adult chat lines (sort of a pre-cursor to IRC). They did a study and found out that a few people (mostly the chat line operators) would connect straight, as you said, all night, and all weekend, tying down the dialouts for the rest of us. There were people (individual users) who'd use it the same but according to Telenet's stuff (wonderful tech support, btw) the chat lines were the biggest problem. Not to mention bugs in the billing software that allowed 24/7 dial in free as long as one connected during plan hours :-) Finally a study was comissioned and determined that the average use was 30 hours a month. New terms and agreements were done to reflect 30 hours a month, with extras billed at some $$$/hour. The billing turned out to be a spectacular problem in itself ... Another problem was that the Telenet founding fathers had all placed their dial out modems in locations close to their business users, i.e. downtown. This created a problem since most BBS's turned out to be in suburbs. For a few months to a couple of years no one really realized it but the dialout exchanges could call local TOLL numbers and cost Telenet some pretty serious money :-). i.e. I would call Detroit, and connect to a BBS in Rochester Hills (same area code, toll call). and it would be ok! They finally figured it out and actually added a few dial outs to cover suburbs (mostly in California). > At some point, Tymnet jumped into it with an offering of their own > which was quite competitive.

PAT] Tymnet was a bit more expensive but had FAR more cities; the support BBS for PC-Pursuit did not allow any messages related to the OTHER service :-) Eventually they stopped accepting new subscribers and it went downhill. Spiros Triantafyllopoulos Kokomo, IN 46902 (317) 451-0815 (8-322) Corporate Software Technology Email: c23st@eng.delcoelect.com Delco Electronics Corporation URL: http://expert.cc.purdue.edu/~strianta/ [TELECOM Digest Editor's Note: In the very beginning early days of PCP, we could not even use the regular dialups. They had a special group of numbers you called in and gave your user id and password. You then were disconnected, and you awaited their callback at the *phone number of record* for your account. That was intended to prevent hackers from getting on with your account. After awhile they changed it so we just called in on the regular dialups. Do you remember when they started adding some large BBS sites with their own @C aliases for direct connection so you no longer had to go to that city and dial out? The large one in Milwaukee comes to mind as does Portal Communications in San Jose, CA. You could reach both of those using your unlimited PCP account by entering something like @C PORTAL on the command line. The thousands of smaller BBS sites had to be reached through the dialouts however. I wrote an article which appeared in Usenet and several BBS's back about 1987 which Telenet thought was scandalous. They were very annoyed with me for writing it. The article was entitled, "Let Your Fingers do the Walking" and discussed all sorts of very obscure things people with PC Pursuit accounts were able to do which they were not supposed to be able to do, i.e. mouse around on the international network 'for free' using their unlimited connection account with PCP during overnight hours. In my list of addresses to connect with, I included the master clocks of several networks. For example, one could do @C something which was essentially an international call to an address in the UK which connected with the British Telecom Master Clock. The display on the user's screen was similar to what one gets now when dialing the NAVOBS modem number. I also included some addresses in Japan which got the same results from a data network there. Just like the telcos used to do years ago, Telenet also had some special addresses that were just 'loop arounds' for testing purposes. If you did @C (that address) it would connect and everything you typed would be repeated back to you. Also, many international data networks had 'manual help terminals' assigned network addresses of their own. If you did @C (those addresses) it connected to someone sitting at a terminal (usually a network technician) at the international point. One I was fond of connected to the technical support employees of the Hong Kong Telephone Company. Still another @C (address) we found was simply a gateway to Canada DataPak as it used to be called. They had in/outdials of their own all over Canada, and we found that by connecting with that address, we could then give instructions to DataPak and use their outdials to make modem calls to the few BBS's which were in Canada in those days. ... it was all pretty wild. Telenet had @C addresses to all the other major networks of the day including Western Union, Compuserve and many others. PC Pursuit users were **never** supposed to go anywhere near any of those. They had a gateway into Arpanet which we know as the forerunner to what we are on now. It just went on and on and on ... my article discussed all those -- one of my infamous 'tutorials' I used to print from time to time. Since PC Pursuit (and Telenet in general) were very popular 'toys' among hackers, getting a valid account id and password were the thing to do. Just as Compuserve and AOL today are getting hacked constantly with some hackers so bold as to go right into chat rooms, pretend to be employees and ask people to give them their passwords ... (yes! and do you know how many users are dumb enough to do it? Enough to make it one of the easiest scams around) ... well, I digress. What they did in those days was someone posted a list of the @C addresses for the dialups into the network. They would connect to that address but instead of taking the modem off hook to make a call out, they would just sit there and wait ... sooner or later, and usually sooner, a call would come in from some unsuspecting person from the other direction; someone using a dialup to get in and log on. The hacker would give them a 'please enter your password' request and then sit there and watch on their side as the caller who had 'glared' at them from the other side typed it in unwittingly. The hacker would then send a message back saying 'network problems, please hang up and dial again ...'. The person would do so, but in the meantime a new victim would hit the line the hacker was hiding behind and while he was tricking that one out of a password, the first one would dial in and land somewhere else on the rotary and go about his business thinking nothing was wrong. When Telenet found out about that, they flipped! They changed the network addresses on all the dialups and also did something to fix them so you could not call them from on the network; they would always be busied out or something from the network side. That ended that little hacker scheme. And do you remember Telemail, which was Telenet's email system for subscribers? If you did @C MAIL you were requested to enter a user name and password. If you entered name: phones and password: phones you got several large files which listed all the network dialup/dialout numbers, their network addresses, etc all over the world. A feast for a poor hacker's eyes. Included were the protocols used for connection to all the international data networks which gatewayed or interconnected with Telenet as well as all the domestic networks such as Western Union, Arpanet, etc, the network addresses used for those connections, etc. The best part of all was the bug in the software which allowed PCP users to tamper with all of it and not get caught. Telenet and the PC Pursuit admins were not at all pleased that I published a very detailed article on the whole thing.

Cuccia Subject: Bellcore TRA Downloadable Files Bellcore's TRA (Traffic Routing Administration) has now added downloadable files to their webpage. TRA maintains the databases of NPA-NXX codes and similar items for the North American Numbering Plan, and they sell various products regarding the NANP available on paper, fiche, diskette, datatape, data-transfer, CD-Rom, etc. The new downloadable files are available from the TRA webpage: http://www.bellcore.com/NANP/tracat.html Near the bottom of this page is an item for Numbering Information Plan Changes (NIPC). Clicking on the line to initiate the download (http://www.bellcore.com/NANP/legal.html) will bring you to a terms and conditions "legal" notice, which allows you to click on a line to continue the download. It is a compressed .exe file which when downloaded and expanded contains a list of new NPA-NXX codes announced for the month. A "readme" file is included, as well as a listing of Operating Company Numbers. It is my understanding that this file will be *REPLACED* with a new one on a monthly basis and that the new monthly file will contain *only* those codes which are still in the process of being changed or taking effect. Some of Bellcore TRA products (available for a fee) will contain "master" listings of NPA-NXX codes as of a certain date and subscriptions to packages (or "one-time" orders of such) which contain updates to NPA-NXX information for that month, quarter, etc. And Bellcore TRA products are usually divided into "routing/switching/ network" information (such as "wirecenters" with their V&H co-ordinates and CLLI codes) and "rating/billing/accounting" information (such as "ratecenters" with their V&H co-ordinates and CLLI codes). The UK's (government) regulatory agency and numbering administrator (OFTEL) has maintained an Internet site for almost a year now, containing similar numbering and code information for the UK. http://www.open.gov.uk/oftel/oftelwww/oftelhm.htm and click to Numbering along with ftp://ftp.open.gov.uk/pub/docs/oftel/oftelwww The ftp site contains downloadable files which are replaced monthly, but their files usually contain all of the earlier information even if it hasn't changed.

Organization: SoftQuad Inc., Toronto, Canada Date: Mon, 6 May 1996 16:59:06 GMT How widely available is the emergency number 911 in the US and Canada these days? Are there any large telcos that don't support it, or where it is supported only in some areas? Are there any that have implemented the new international emergency number, 112, in addition to 911? (Ideally, I'd like to see an answer of the form "911 can be called from 91% of all prefixes in the US and Canada. The largest company not offering it is AcmeTel, of Acme, XX." Well, really I'd like to see the answer that 911 now works from everywhere, but somehow I doubt that!) I'll throw in a few other questions in case someone has answers: * How much territory where 911 works has enhanced 911 (i.e. the caller's address made available automatically to the dispatcher)? * How widespread is the spelling-for-idiots version 9-1-1? * Is 911 used in the Caribbean countries that formerly were all in area code 809?

The Commission has the right to control junk calls, but they haven't really used it. If you wish you had the right to stop those calls, without interfering with the rights of others to receive the calls if they so wish, you may want to let the CRTC know. Bell Canada and BC Tel have asked for "limits" on unsolicited calls. The phone companies, in a letter to the CRTC have asked for a tariff change that would do two things: * to require telemarketers to add your name to their "do not call" list within 7 days rather than the current 30 day grace period. * to limit unsolicited faxes to the hours between 9:00 a.m. and 9:30 p.m., Monday to Friday, and between 10:00 a.m. and 6:00 p.m. on Saturday and Sunday.

PAT] Incorrect in the Chicago land area with Cellular One and Ameritech land line. My Ameritech (home) has CID. My cell phone is setup to call forward on RNA, BUSY, OUT-OF-AREA, or OFF and it passes along the CID information no problem. I do NOT subscribe to CID for the cell phone either. Also, my cell phone (when making a call from it) DOES pass along the CID informaiton for those who can recieve it. It shows up as "Cellular Call" with my number listed. Originally it did come up as "Anonymous" but I asked to have that switched as my home line blocks blocked calls ... Also, with land line phones I tried the following: forwarded calls from a line (no CID service on that line) at the office to my home. Office is Centrex and home is POTS. Caller id on the POTS line showed up from calls originally placed to the Centrex line but was passed along to the POTS. I'm not sure about hunting though ... can't do that test easily (yet :-) as we don't have CID on the line(s). That will be coming shortly as our phone system and phones have displays and can handle the info. ------------------------------ From: danny.bain@pobox.com (Danny Bain) Subject: Re: Does Caller-ID Hunt or Call-Forward?

What wasn't mentioned here is that when a call is passed from Line A to Line B via this hunt process, the call will hit Line B with caller information for Line A rather than the actual calling party. This is true in my telco, at least. The call id information for the calling party is only shown if the first line answers and is subscribed to caller id. ------------------------------ End of TELECOM Digest V16 #221 ******************************
