For the other ninety-nine percent of the computer-using populace, Lemay has written a solid, realistic, well-paced and readable introduction to the topic. Having seen numerous recent exhortations that "Web publisher" is one of the "coming" jobs, I hope she makes a fortune. The fourteen chapters give a thorough coverage to both HTML tags and W3 page design. Topics include background; presentation and page design; basic, linking, formatting, media and form tags; examples; W3 servers; gateway scripts; and HTML tools. Appendices list further resources and a summary of commands. The "in a week" timeframe may be stretched by the forms and gateway scripting, but a dedicated student equipped with server and browser should be able to be well familiar with everything in the book after seven days. Lemay's pacing, organization and structure are sound. The content is clear and the text quite readable. Given the subject matter, some of the typos are ironic, but none should be a hindrance. In fact, the only problem I have with this book is that nine out of every ten readers will be using it to turn out the same guff we've seen on twenty thousand other Web servers. The ones, though, might make it worthwhile. copyright Robert M. Slade, 1995 BKWPHTML.RVW 950322. Distribution permitted in TELECOM Digest and associated publications.

Chapter one is a lesson in HTML (HyperText Markup Language). It covers elements right up to multimedia and forms. The overview, though, is quite brief. Anchors are explained as links to other documents, but the function of linking to a specific section of a document is not covered. This function *is* covered in chapter two, which details all the HTML elements, including those proposed for HTML+. Subsequent chapters deal with Universal Resource Locators (URLs); the Common Gateway Interface (CGI); tools, editors and document translators; browsers; servers; and examples. The material is technical and detailed, right down to mention of security considerations on clients. The pace and technical level may not be suitable for beginners, who may want to look at Lemay's "Teach Yourself Web Publishing With HTML" (cf. BKWPHTML.RVW). The organization of the all important second chapter takes some getting used to. The anchor element is included with "List Elements", is not referenced by the "anchor" entry in the index, and the "A element" index listing is out of order. copyright Robert M.

LAUDERDALE, Fla., April 24, 1995 -- Siemens Rolm Communications has entered into an agreement with Newbridge Networks to offer the entire Newbridge product line, a move that greatly strengthens Siemens Rolms wide-area, voice/data network integration capability. The agreement, announced at the National Rolm Users Group conference here, significantly enhances the NetAsset networking products and services Siemens Rolm offers through its Network Systems Group. The Newbridge line, one of the broadest in the networking industry, includes time division multiplexers, frame relay and LAN products, ATM switches and Newbridge network management systems. Siemens Rolm will sell Newbridge products under a joint NetAsset/Newbridge label, and it will support all Newbridge products within its accounts. "Having access to the entire Newbridge line extends the breadth and depth of our offerings," Siemens Rolm President and CEO Karl Geng said. "Newbridge is a leader in technologies such as TDM, frame relay and ATM, and its single-platform architecture lets our customers easily migrate from one technology to another as the need arises." International Data Corporation (IDC) ranks Newbridge first in the worldwide T1/E1 multiplexer market, first in ATM enterprise switch installed base and second in frame relay revenue*. "Siemens Rolm views networks as strategic assets," Geng added. "Our strength is our ability to put it all together. We substantially simplify network operations and reduce cost by consolidating voice and data networks, reducing the required number of circuits. We also provide a single contact for sales, implementation and support." Sandy Teetsel, director of I/S technology services at Mercy Healthcare Arizona in Phoenix, said, "We needed to expand our network quickly to support remote locations statewide, but we did not have sufficient internal resources to plan, implement or support the project. Few integrators can provide voice and data services, as well as offer full support. Most can tell you technically how to do it, but then you are on your own. They lack the depth of understanding of strategic applications and cost-effective support. But Siemens Rolm brought all the right players to the table." Newbridge Networks Inc., President Mike Pascoe said, "We selected Siemens Rolm because of the synergy between our companies. We believe their products and after-sale support, coupled with our networking capabilities, enable them to provide superior turnkey solutions." Pascoe added that the Siemens Rolm installed base of more than 35,000 systems and its nationwide sales and support organizations offer Newbridge a large additional channel for sales and service: "Customers in markets such as health care, education and financial services will now have greater access to Newbridge products." Curtis Price, research manager for data communications at International Data Corporation, said, "The depth and quality of the Newbridge line puts Siemens Rolm in an even stronger competitive position in regard to turnkey networking solutions." This agreement builds on an existing relationship between Siemens Rolm and Newbridge, which has already resulted in a number of sales. Newbridge Networks is a world leader in designing, manufacturing and servicing a comprehensive family of networking products and systems that deliver the power of multi-service communications to organizations in more than 100 countries. It has facilities throughout the United States, Canada, Latin America, Europe, the Middle East, Asia and Australia. Newbridge Networks Corporation common shares are traded on the New York Stock Exchange (NN) and The Toronto Stock Exchange (NNC). Siemens Rolm is a leading provider of private telecommunications solutions. The company pioneered the digital PBX and integrated voice messaging and is at the forefront in developing advanced CTI applications and integrated voice/data networks. Siemens Rolm is part of Siemens Private Communication Systems, the world's largest supplier of private telecommunications systems, with approximate annual sales of $4.2 billion and more than 450,000 customers and 900,000 systems installed worldwide. # # # * International Data Corporation, March 1995 Siemens Rolm is a registered trademark of Siemens Rolm Communications Inc.

Certain phones (such as Meridian 2616) have a display on which the caller's name and number are displayed for any incoming or outgoing call. I have noticed that when we place a call to or receive a call from a number OUTSIDE of our company, and the phone at that number is also being served by an SL100 (or DMS100), the distant caller ALSO sees my name and number, and I see the distant caller's name and number. I recently noticed this when a friend of mine at our company called a hotel which happened to have a DMS100. When the hotel operator transferred him "anonymously" to a certain room, the hotel guest's name and room number popped up on his display phone! Nice security. I only barely understand what is going on here and I'd like to know more. Specifically, 1. I can understand how a distant phone user might get my phone number, via the standard Caller-ID signaling mechanism. But is the additional information (the string including my name and my extension) also transferred to all phones as part of the standard Caller-ID signalling mechanism, or is this indeed part of some Northern Telecom- specific protocol that somehow piggybacks its way over the public net? 2. Regardless of the answer to #1, can someone point me to a spec describing the signals used for Caller-ID (I understand they are wedged between the first and second ring in a call) ? I'd like to understand exactly what kind of information is carried by this protocol and how. 3. If the additional information from #1 is carried in an NT-specific signal, can someone point me to a spec for the NT-specific signal? 4. Can someone explain exactly what the deal is with Caller-ID and California? What forms of Caller-ID are allowed and what aren't? What are the restrictions on calls that are CA-to-CA, CA-to-outside, and outside-to-CA ? If this is an FAQ item please lead me to the right place. 5. If the additional information from #1 is carried in an NT-specific signal, is that signal also subject to the same legal constraints in California as "standard" Caller-ID information? Thanks, Chris Pirazzi ------------------------------ I'm looking for pointers to phone encryption products, for voice calls, both cellular and desktop. I've seen some product flyers from Transcrypt, but that's it. Any information or pointers to sources would be appreciated. Ben ------------------------------ I just had two AT&T long-distance calls charged to my number, and had to call AT&T to have them removed -- AT&T isn't my long-distance provider. How / why is it possible for someone to have calls -- especially long- distance calls -- charged to my number? Is there any way I can detect this happening or prevent it in the future? Alex P. Madarasz, Jr. - Hughes Training, Inc. - alex@eagle.hd.hac.com ·_ [TELECOM Digest Editor's Note: You can prevent it from happening with a slight bit of inconvenience to yourself, but it may be worth it. Find out of your local telco offers 'billed number screening'. This is a database used in common by AT&T, Sprint, MCI and a couple other long- distance carriers which prevents anything but direct dialed calls from your actual telephone from being being to your account with the exception of credit card calls. That is, calls made 'collect' to you will be turned away as will attempts to bill 'third number' calls to you. The network simply won't allow those calls. Now if *you* have reason occassionally to call your number collect or place a call and bill it to your number, then you too are going to be rejected, but this may be a minor issue considering all the options available these days such as 800 numbers, calling cards and other methods. PAT] ------------------------------ Does anyone know what sort of phone system is used on the island of St. Maarten (Dutch side)? Specifically, if I bring my laptop, PCMCIA modem, and RJ-11 cord, will I be able to connect to the phone system and dial out? (Right now I operate using the US phone system; in Boston, MA specifically.) Thanks in advance, John Irza jirza@marinet.com ------------------------------ As most of you know, the new 911 law was signed by Governor Jim Edgar on September 1, 1994 (Public Act 88-604). The law requires, in our case, colleges and universities, within the state of Illinois, providing "private residential switch service", to integrate with the E-911 centers by June 30, 1995. Ameritech has not been able to handle the requests for integration. Partly because, Ameritech just completed and submitted the tariff requests for approval. It is my understanding that if no opposition is given within 45 days, the following tariff requests will be approved. I was given the following information, VERBALLY by Ameritech. Each college and university would need to set-up and maintain an ALI (automatic line identification) database in the Ameritech 911 center database. The requested tariff for this service is: one time set-up fee $5,000.00 monthly access charge $ 109.00 (additional, changes, deletions) Each college and university would be required to have at least two trunk lines which would be dedicated to 911 traffic. one time installation fee $450.00 monthly Trunk (line) cost $ 65.00 / trunk If anyone can add to this, please respond accordingly.

Gladstone Avenue Aurora, IL 60506 ------------------------------ Hi, As I arrived at Atlanta Airport, I bought a prepaid phonecard from U.S. Telecard. I was very happy about the message features. I had a special message PIN (different to the PIN which is needed to place a call), who allowed anybody who knew the PIN to leave me messages. This call was free for the caller, only I had to pay 80c for each message. Now, I would like to use this feature for international calls (especially from Germany). The problem is, that 800 numbers can not be reached from outside the U.S. So I would like to know if there are calling-cards (prepid or not) with an international message feature. I am interested in general inform- ation about calling-cards too. Thank you very much for your help in advance. Thomas Feiner Munich, Germany ------------------------------ The following is an announcement by the U.S. FAA Technical Center that was published in the April 14, 1995 issue of the {Commerce Business Daily}. I am cross posting it here in hopes of reaching a wider audience. ------------------------ Special Studies and Services - Not R&D - Potential Sources Sought Federal Aviation Administration Technical Center (FAATC) Atlantic City, NJ 08405 Sources Sought, suppliers of voice digitizing equipment for evaluation of applicability to Air traffic control applications.
