Feb. 14, 1994 GTE BRINGS HIGHLY ADVANCED TECHNOLOGY TO CALIFORNIA THIS WEEK; "WORLD CLASS NETWORK" A REALITY GTE California today announced that it will install highly advanced switching technology this week in the Los Angeles area as part of the company's continuing effort to build a "World Class Network" for customers. The company said ATM switches -- some of the final components that permit access to the information superhighway -- will be installed Tuesday (Feb. 15) at company facilities in Santa Monica, Ontario and Thousand Oaks. Additional ATM switches are scheduled to be installed at other California sites before the end of the year. ATM (Asynchronous Transfer Mode) switches handle simultaneous video, data, image and voice traffic. A few of the customer service capabilities include: interactive distance learning among classrooms in different parts of a city or state; geographically distant employees sharing documents and images during video conference calls; medical experts in separate hospitals concurrently reviewing and diagnosing X-rays; and residential customers picking movies from video-on-demand libraries. GTE's ATM network initially will support educational institutions, businesses and government agencies. "The 1990s have been a challenging time for California, but also an exciting time as we work to build a future that's better than our past," said West Area President Larry Sparrow. "We've been aggressively installing advanced network systems here for several years. The addition of ATM switching makes our long-standing vision of a World Class Network a reality." ATM SWITCHES PART OF GTE PLAN TO SUPPORT EDUCATION Educational institutions are a critical component of GTE's World Class Network in California. More details of the World Class Network's educational aspects, as well as business and government applications, will be announced at a later date. "We've proven the value of telecommunications in the classroom, and we've learned that no single product can meet the diversity of needs present in our schools today. Another difficulty educators face is technological obsolescence," Sparrow said. "GTE will ensure that educators have access to technology that meets their individual needs. ATM's flexibility will help schools avoid dependency on technology that will become outdated." Using telecommunications, schools can improve the quality of education by pooling resources and accessing a tremendous variety of information and learning materials. The company has conducted several educational pilot projects, including programs in the Hacienda-La Puente and Norwalk-La Mirada school districts, and a distance learning program with California State University, Dominguez Hills and Coastline Community College. GTE also has conducted the world's most comprehensive technology test of educational applications as part of the company's Cerritos Project. ------------------------------ Date: Tue, 15 Feb 1994 13:42:29 -0500 From: Dave Banisar <cpsr@access.digex.net> Subject: Over 10,000 Sign Petition to Oppose Clipper Washington, DC February 15, 1994 Computer Professionals for Social Responsibility (CPSR) OVER 10,000 SIGN PETITION TO OPPOSE CLIPPER In only two weeks, over 10,000 users of the nation's computer networks have signed the CPSR petition calling for President Clinton to withdraw the Clipper proposal. Opposition has been widespread, from CEOs of large firms to college students in small towns, from librarians and civil libertarians to computer programmers and product marketers. To sign the petition, email <clipper.petition@cpsr.org> with the message "I Oppose Clipper" Encourage friends to sign. In 1990, over 30,000 people sent email message to Lotus asking that a product containing detailed personal information called "Marketplace" be withdrawn. Eventually Lotus withdrew the product. CPSR is a non-profit, membership organization based in Palo Alto, CA. CPSR's mission is to provide analysis of the effects of new technological developments on society.

The README file is in ASCII format and may be read on any word processor. The other files in the directory are in PostScript format and may be downloaded as needed by using the "mget" command while in the FTP. The PostScript files may be printed on a PostScript printer by using the "lprr" command. A typical Post Script print command may look like: lpr -P<printer> -h -v <filename.ps> where: <printer> represents printer name on your network, and <filename.ps> represents a PostScript file. '-h' corresponds to the option of suppressing the printing of burst page while '-v' corresponds to the option of printing raster image, i.e., PostScript. Please note that the printer must support PostScript imaging model in order to print these files.

Russia is beginning to offer tone-dialing (very limited number of exchanges even in Moscow), but as long-distance direct dialing is very common, standard (?) caller ID request/responce are used. It is worth to mention that in Russia all seven-digit calls are local (flat rate), so the problems with billing only begin when you call 8 (wait for dialtone) (area code) number. Your caller ID is requested after you dialed 8. If it failed after several trials or callback probe realized that the number is not busy (i.e. it is forged or incorrectly recognized), you get engaged tone and need to hang up. (International calling is 8 W 10 + ....; this 10 looks more familiar, eh?). Of course, there is nothing like custom calling services. (You cannot _dial_ * or #, can you?) That's why hardware-knowledgeable people began to create their own devices (mostly Z80-based, with 4K of ROM) to perform basic caller ID functions. Algorithms were getting better and better, and now such a device does caller ID (buffer for about 10, time and date), white (distinctive ringing), grey (regular) and black (rejected) lists of caller IDs, repetitive dialing, "answering machine" (outgoing message from RAM, incoming to an attached tape recorder), etc., etc. Very impressive, especially for those who understand that there is 1-bit FFT inside. What happened next -- it became almost impossible to call long distance, because the number of caller-ID generators was limited and if all of them on your local exchange are busy when you call long distance, it doesn't get your ID and rejects you. That's why the Ministry of Communications decided to introduce the fee for caller ID boxes. But it is not the end of the story. As those boxes are cheaper than answering machines, people used them in AM mode when leaving home, that is when you call a number equipped with caller-ID box, it picks up after the first ring, sends the request, decides what to do with you, and either simulates busy tone or hangs up (you're rejected) or simulates ringing and really rings the phone, but nobody answers. It is very annoying if you call from a payphone, that's why it is considered very impolite to set the device in AM mode. (regular mode is to detect ID after the receiver went off hook). Of course, anti-caller-ID were developed, but they work quite unreliably -- just trying to send pulses after remote picked up. Sometimes it helps, sometimes not. Last note: as the system was designed for billing, the ID only contains seven digits, so it is impossible to derive area code from ID, the best is to recognize "alien" phone number. I hope it was of interest, Leo [TELECOM Digest Editor's Note: Yes Leo, it was of interest. Thanks very much for passing it along, and please tell us more about telecom in Russia from time to time.

Date: Tue, 15 Feb 94 14:02:47 GMT My in-laws have a new Motorola flip phone that they love very much. They recently took a trip to Florida and while driving on Rt. 95 the phone rang and they got some sort of a "welcome" message from one of the local service providers. My FIL is constantly amazed by all the technology at work here and he would like to know basically how this works. I assumed that the phone, while in standby, can detect when it enters and leaves each cell. And when it sees that it enters the cell of a new carrier it (the phone) transmits some sort of a "here I am" message obviously this includes his phone number or some sort of serial number so that the cell can call back with the "welcome" msg. Is this about right?

Kimberlin <0004133373@mcimail.com> Subject: Request For Map Drawing Software I'm getting into software that draws network maps on the fly as people use it, with need to zoom in and out and place variable labels, like node names, on the maps, and have them ultimately printable on an attached printer or fileable in disk files. Can anyone suggest sources for some nice geographic outline map drawing code for PCs? The U.S., Canada, and world political outline maps are all ultimately needed. Windows/DOS preferred, but UNIX is acceptable, at least to try with. Ultimately, I will need to get the source to make modifications as to labeling and such. Commercial products are acceptable, but public domain is preferred. The choice depends on cost. All replies appreciated.
