%T "Teach Yourself Web Publishing with HTML"
For those of us, hoary old techies that we are, who had to deal with
TeX, SGML, and the manual insertion of escape codes into documents for
the earliest laser printers, HTML (HyperText Markup Language, the
instruction set for World Wide Web) holds no terrors at all. 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.

%T "HTML Sourcebook"
For those who are serious about creating World Wide Web pages and
presentations, this is a very thorough reference.
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.

SIEMENS ROLM and NEWBRIDGE TEAM TO PROVIDE INTEGRATED SOLUTIONS FROM
DESKTOP ACROSS ENTERPRISE TO WANS
Siemens Rolm Enhances Wide-Area Network Integration Capability With
Full Line of Newbridge Products, Including ATM
FT. 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.

We have a Northern Telecom SL100 switch at our company. 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.

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?

[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,

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.

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.
