Subject: CFP - Home Informatics International Conference
Organization: IFIP WG 9.3
Date: Mon, 13 Dec 1993 14:25:57 GMT
A cross-disciplinary international conference
HOME-ORIENTED INFORMATICS, TELEMATICS & AUTOMATION
From 'State of the Art' through 'Prospects'
and 'Blueprints' to 'Implementation'
organized by IFIP Working Group 9.3
in cooperation with the University of Copenhagen
University of Copenhagen, Denmark
June 27 - July 1, 1994
BACKGROUND
The home offers a great potential for new automation, information and
communication technologies and related services. A wide array of
innovations are already under way, with many more to come. They will
transform the home and everyday life in the emerging information
society. They will condition how private households will be enabled to
function in changing social, economic and political structures.
AIMS AND SCOPE
The conference will assess and conceptualize perspectives and options,
which attach to developments of domestic informatics, telematics and
automation across the levels of
- consumer hard- and software,
- network infrastructures
- storage & distribution media,
- teleservices and
- socio-cultural & economic structures.
How can these new technologies - seen together - be used to empower
consumers and private households?
How can both users and suppliers get the optimal benefits from the
possible new technologies? - and with which global impact?
Can these technologies contribute to the emergence of a new home
concept, an "Oikos", where the private household can reestablish itself
in an experienced way as a living and production centre, embedded in
and interacting with a larger community?
Addressing such questions requires a multi-disciplinary approach.
Therefore the conference aims to bring together experts from many
fields and disciplines. Researchers and practitioners, designers and
users, policy makers and industrialists, each with new knowledge and
new questions from their experience of recent and expected
development.
The conference will not only serve as a forum to present and exchange
experience, results of research and ideas, but also to explore and
discuss strategic approaches and alliances for product research and
development, and for prototyping and field experiments.
MAJOR THEMES
* The social construction of new domestic technologies.
* Bridging between the various disciplinary approaches.
* The changing position and importance of households in the new social
and economic structure of the information and communication society.
* Strategies for creating professional and public awareness of the
converging potentials and implications of constructive innovations for
everyday life and for social, cultural, educational, health, energy,
and economic policies.
* Ways of organizing relations between research and product
development which can further the long-term interest of consumers, and
save producers from waste of investments in development of products
and services which are doomed to failure.
* Relevance for developing countries, cultural diversities and the
general goals of the UN year of the family 1994.

Subject: History of Blue Boxes

Organization: Opinion Mongers Incorperated...
Someone posted an (unattributed) note to the effect that blue
boxes had been around "10 or 15 years". This is wrong - try 40 years
or so.
For what it is worth, blue boxes have been around almost as
long as the underlying MF in-band address signaling that they exploit
(since 1948). And will probably exist until there is none of this
left (we're getting there).
The first one I am certainly aware of was built by an IBM
engineer working on some sort of government telephone switching
project in or around 1957. I have heard rumors of the devices being
built by other engineers in the telephone R&D community significantly
before that time but have never heard any definate proof one way or
the other as to the actual existance of such or to their use for
hacking. These early devices of course mostly used vacuum tube
oscillators and relays rather than the software and sound board
approach that is common now.
The famous "Blue Box" which gave the device its common name
was the fruit of a hacking project at MIT and Harvard in 1960 or 1961
and was in fact really a blue metal box. I suspect but do not know
for certain that that this project which ended in criminal legal
negotiations between the students involved and telephone security
personel was the first time telephone company operating management
became widely aware of the potential of such sophisticated (at least
for its time) toll fraud. I was told at the time that the president
of the New England Telephone Company was absolutely flabbergasted when
he was told of the technology and given a demonstration -- before that
time operating telco management has no idea whatsoever that such
things were even remotely possible.
One suspects that the spooks knew of the technology earlier
than this and no doubt kept the secret classified just as they did
many other holes in the security of society so they could exploit them
for "purposes of national security".
The first public discussion of blue boxes that I am aware of
was an article in the {Boston Herald} in 1964 or 1965 that resulted
from a political fight between the {Boston Herald} and the New England
Telephone Company. Apparently the Herald felt that the Telco had
screwed them in a legal battle over a story they had published earlier
and got revenge by printing the blue box story which they had known
about for some years (since 1961 or so) in order to damage the telco
since it was known that it would take years to plug the holes that
blue boxes exploited.
By the time this article was published, the technology of
telephone signalling and automatic billing and its weaknesses was
fairly well know amoung the nascent MIT centered hacker community and
blue box projects were common amoung students there.
Blue boxes surfaced nationally in the media in 1971 when
{Esquire} published an article about them. But by that time the
telephone industry had mounted an aggressive campaign to prosecute and
monitor blue box use and the whole matter had become one aspect of the
ever present toll fraud problem rather than a marvel that stunned
senior managment.

Does anyone know where I can get a programming manual for my NOKIA M10
cellular telephone? I would like to change the "default" lock code ...
or am I stuck paying my cellular provider to reprogram it. Thanks.

Subject: Prodigy-Nynex Online Yellow Pages
Nynex announced plans to team with Prodigy in the first ad-supported
on-line interactive Yellow Pages system. The database, consisting of
some 300 on-line telephone books, is expected to be available by the
end of next year. The service will be delivered over Prodigy's
network and will be owned exclusively by Nynex. The listings can
include photos, maps, menus and up-to-the minute information, such as
interest rates at banks. Nynex plans for the system to eventually be
interactive, whereby customers could make reservations on-line.
Subscribers will not be charged for the service since it is supported
by advertisers, and businesses would only pay for advertising beyond
their name and phone number listing. The team plans to push other
regional telcos to join them in listing and selling Yellow Page
advertising on-line. The value of the agreement was not disclosed.

Subject: Call Return on Pay-per-Use Basis
[from Bell News, Bell Ontario, 13 Dec 93]
We get thumbs up for two pay-per-use services:
Last Call Return and Busy Call Return
Last Call Return and Busy Call Return -- two calling features normally
available on a subscription basis -- are now available on a
pay-per-use basis to individual-line residence and business customers.
The features were offered on a three-week, free-trial basis starting
November 8, in Belleville and Trenton, Ontario and Sherbrooke and
Magog, Quebec. They became available in Ottawa-Hull and Quebec City as
a full service on November 29.
A charge of 50 cents applies for each use of last call return or busy
call return, up to a maximum limit, or cap, of $6.00 per month (plus
tax).
Both capabilities have been available to Bell customers on a
subscription basis. Customers can use Last Call Return and Busy Call
Return for local or long distance calls within or between areas where
the features are available.
The features will be introduced in other Ontario and Quebec
communities where calling features are now offered, on a phased basis
during the first six months of 1994.

Since the LATA boundaries aren't changing (only the dialing), why
would the LD carriers be upset (assuming no IXC defaults are changed).
Won't the same calls to the same inter-LATA numbers still use the same
IXCs? The IXC sure can't tell that you dialed a '1+' at the beginning.

Bad guess -- first of all, Bellcore didn't exist when the 10XXX
dialing plan was devised, but many folks from AT&T that worked on the
plan became Bellcore employees in 1984.
Secondly, 10xxx can validly appear in front of any standard numbers
of 7, 1+7, 10 or 1+10 digits, assuming you could dial them without the
10xxx prefix. I just tried calling myself using:
NXX-XXXX (IBT oops, I mean Ameritech)
1+708+NXX-XXXX (ditto)
10288+ 1+708+NXX-XXXX (AT&T)
10222+ 1+708+NXX-XXXX (you know who)
10333+ 1+708+NXX-XXXX (ditto)
10288+ NXX-XXXX (AT&T)
10222+ NXX-XXXX
10333+ NXX-XXXX
These all rang the "second line" on my ISDN set. No form of
1+NXX-XXXX worked -- IBT intercepted. But if IBT permitted it, 10XXX
could precede it. All the forms with 1+708 could also be 0+708. IBT
doesn't support 0+NXX. The only form of 10XXX access that doesn't
work are those where your presubscribed carrier would not be selected,
such as 1+800 or 1+900 calls. Note these shorthands:
00 = 10XXX+0# IXC operator
0# = LEC operator
Also, 10XXX+# is cut-thru to IXC dial-tone (sorta like 950-0XXX).
There is no shorthand for this access, since '#' by itself is an
error.

Correct me if I am wrong. Exactly the opposite happens. The 0015 lines
primarily use the satellite route while the 0011 numbers has the cable
route when ever possible to provide better voice quality (no echoes).
Apparently the fax machines are immune to echoes. I got these from a
telecom rep.

Subject: Re: Emergency Services Will be Elsewhere in a Moment, Sir
I don't know what would be displayed if I had to call 911 from my
present phone on 410-287; my mail (including my phone bills) goes to a
PO box in another town. Utility companies need to know where you
live, because that is where the physical connections for service
(electricity, phone, etc.) go, even if the bills don't. (Perhaps
you'd want to find out what exchange serves 820 Old Apex Road. I did
find Apex Road and Street listed for zipcode 27707, and Apex Hwy.
listed for zip code 27713, both in Durham.)
Question: What about foreign exchange service? An old example in
Maryland was someone in an area served by 287 prefix who brought in
642 Perryville (the next exchange to the west) as a foreign exchange
because it is local to Aberdeen (272,273,278) and Havre de Grace
(939). Another case (glaring because a state line is involved, and I
recall seeing this at least once in the Wilmington, Del. directory),
would be someone in the Wilmington or Holly Oak exchange area bringing
in Chester Heights (Pa.) as a foreign exchange; that choice:
-Keeps Wilmington, Newport, Holly Oak as local calls
-loses local service to other parts of New Castle County, Del.
and part of southern Chester County, Pa.
-GETS LOCAL SERVICE TO ALL OF PHILADELPHIA METRO AREA
Remote-forward, which I set up in Delaware, would not be involved in
911. No calls can originate on my Delaware number; it can only be
activated by an incoming call, and can only automatically call the
number I am forwarding to.
