== NSA Editorial ==
Welcome to National Security Anarchists Issue 4. Yes we at NSA do admit this
Issue has taken some time since our previous releases. Not to worry NSA is
still in existence and we shall continue always. Why for the delay, Muds.
Trust me, Muds eats Hackers. If you are planning to play muds, Rest assured
that you best say bye bye to your Hacking Career. As I type this
Introduction, Dead Addict is blabbing "Dick Van Dyke, Starring Dick Van
Dyke". And has raised an interesting question. Why do these old shows have
separate beds for the Married Coupled. And also these Married Couples have
Children?!?
Many of you have raised a point that is obvious. We copy our material from
books/trash/manuals. Yes we do and we always have admitted it. Our Motto
states "Plagiarism is the Basis of Creativity". Why do we copy straight from
the manuals/trash? Simple! The best source of Information is from the
Source. Here is a simple analogy to explain it even more. Information is a
juicy Steak. And Most groups take this information and reword it. Thus this
is Second Hand teaching, and plus you are learning what they learned.
Therefore that is in comparison to chewing up a steak and feeding you
tasteless bits. Now we at NSA give you that Steak, unchewed, unprocessed, so
you to can enjoy that same flavor that we experience when examining this
material.
Also many of our readers have made several interesting ideas and comments for
the newsletter. Now The Serious Side of Hacking is available in this
Newsletter. What is The Serious Side of Hacking, well let I'll let Dead
Addict explain his section.
NSA has released SlimJim Version 1.0 into the Hack/Phreak world. SlimJim is
a Unix Utility for MS/DOS machines. SlimJim slims those large password files
and makes them smaller. Plus SlimJim is very fast even on IBM XT compatible
computers, and saves you space at the same time. SlimJim can be found on
various Hack/Phreak boards.
Soon Silicon Slave Version 2.0 will be released. Yes, another Hack/Phreak
utility from NSA. Silicon Slave is a collection of common Hack/Phreak
utilities incorporated into one program. Details will be released later.

== Anti-Pirate Video Techniques ==
== GTE Project 358 ==
Project 358 continued to explore video techniques in areas of copyright
protection, scrambling, and video storage. Emphasis was placed on
development of hardware and software to demonstrate the feasibility of
network-based copyright protection. Figure 358-1 depicts VCS functional
blocks. The copyright protection scheme encrypts video material by
scrambling each vertical field and embedding program serial number, field
number, and error correction codes in one horizontal line of the vertical
blanking interval (VBI). Public domain encryption techniques are used to
recover 15-bit pseudo-random descrambling codes. Decryption requires the
keys(s) provided by a remote database, accessed through a low-speed
communication link (telephone network). This allows viewing control and
revenue collection by intelligence in the remote database, but facilitates
copying and distribution of protected material.
The encryption scheme has two levels, one for protection of video
descrambling codes embedded in the VBI, and one for protection of messages
between the home and the remote database. The encryption technique assumes
the potential pirate knows the encryption algorithm and demonstrates years of
work time to decrypt protected material without database-controlled keys.
The copyright protection scheme provides high-integrity protection of video
material until the key(s) is released, which provides security for live
broadcast and/or the recording and distribution phase of video cassettes.
While there are various schemes for protecting decrypted material from
copying during viewing, including locating the decryption function inside a
special TV or video monitor, none of the schemes provides significant
protection from the sophisticated pirate.

This project supports the implementation of a small field-deployable viewing
control-copyright protection system. Results will be used as building blocks
to define a viewing control field demonstration for the Cerritos ][ testbed.
The past year has seen the development for VCS of MCU software that is
modular
for flexibility during further development, yet does not exhaust the capacity
of the Motorola 6805 microcontroller and is able to operate within the bounds
of visual field time. VCS processing in the microcontroller of the Home Unit
is now able to serve three levels of message encryption and apply up to five
scrambling keys to each video program. It can also handle midtape video
start, viewing time control, and session cancellation. Developments of
message overlays and application of "anti-pirate" copy signatures are now
under way and are scheduled for completion in the 1991's.
A significant effort during 1990 was the design and implementation of a
unique scheme for generating robust scrambling codes that preserve the
smoothness of the presentation. The method is based upon encryption of
successive field numbers. It produces scrambling codes that are uniformly
distributed and unpredictable, hence largely pirate-proof, yet can be easily
recovered by the system when videotape flaws prevent reading of field numbers
from the tape itself.
Six patents were filed on viewing control system techniques during the year.
Preliminary meeting were held with three studios, one TV manufacturer, and
one anti-taping technology company. A presentation was also made to the T3
Standards Committee.
This project also supports activities relating to standards, including
attendance at T1Y1 and HDTV groups, as well as the EIA Multiport Receiver
Group. A North American standard for compressing digitized video is under
active investigation by the T1Y1.1 Experts Group on DS3 TV. GTE Laboratories
had increased activity in this field by attending the meetings held by the
Experts Group. These meetings are usually attended by representatives of the
T1Q5.5 Experts Group who are concerned with performance standards for
digitized video transmission and represent the broadcasters and others.

== The Challenge of the Industries ==
== Dennis C. Hayes ==
== Speech at BellCore's CPE WorkShop ==
== Contributing Writer ==
== Mobius Drux ==
Below is a capture from HAYES, it is from the President of Hayes speaking on
the future of ISDN. Hey, folks this is the future so it would be to your
advantage to at least know whats going on.
"Waiting for ISDN to Happen..."
That phrase is a phrase that is seen often -- in magazines we read -- in
speeches we hear or in meetings we attend. "When will ISDN happen?" Our
market and product planning departments ask. Our customers ask. The
analysts and media make their predictions.
In the last two years, the magazine articles and speeches are changing:
something has happened. In the last year people are now questioning
"WILL ISDN ever happen?"
As for the question, "Will ISDN ever happen?", we all know the answer is
yes. ISDN will happen and ISDN is happening. The countries in North America
cannot afford to allow our communications services to be incompatible or
non-competitive with communications services used by our companies' and
America's global competitors. ISDN is happening in Europe and is beginning
in Asia and our region of the world cannot afford to be left out. ISDN must
happen in North America.
But there is a perception problem and the members of our computer and
telecommunications industries must solve the problems that still inhibit the
commercialization of ISDN.
If we were to graph the public interest in ISDN, we would see a "Spike of
Expectation" during 1986 - 1987 -- even into 1988. People believed that ISDN
would make an impact on businesses and were excited about the possibilities
of using this technology. But when the expectations were not met,
excitement was followed by a "Valley of Disappointment." We must begin
building the excitement again -- but at a realistic level of steady growth --
where the public interest matches the industry's capability. A steady
growth of capability over the next year or two will rebuild confidence. We
must provide concrete and tangible evidence of this steady growth of ISDN
deployment on an ongoing basis. Keep in mind the person who has to make the
decision to buy the service. What makes the MIS Manager or Telecommunications
Manager buy the service and products that implement ISDN? What makes them
convince the CIO that ISDN is worth the investment?
The COS (Corporation for Open Systems) announcement about ISDN 1 has
rekindled public interest and is a step in the right direction, but we and
all of our colleagues in the industry must remove the real and perceived
barriers to successful commercialization.
Part of the problem that caused the "Valley of Disappointment" comes simply
from the concept of time in the computer industry being so different from the
concept of time in the telecommunications industry.
The computer industry: predominantly data oriented -- and not regulated.
People expect computer technology to change rapidly and it usually does.
It is much easier for the computer industry to develop new products because
they do not face the barriers that the telecommunications industry faces.
Look at local area networking. It took several years but it was fairly easy
for the computer industry to bring that technology into businesses. LANs
were market and technology-driven applications that faced no regulatory
barriers.
The telephone industry, on the other hand, is a much older industry that is
affected by a number of restraints which throttle change: compatibility with
the existing network and the federal and state regulatory barriers -- just to
name two.
The telephone industry's roots are with voice services to residential
customers even though data traffic is rapidly growing. There is less
understanding of data services and very little understanding of the
integration of voice and data by most employees in North American telephone
companies.
So the two different cultures must meet. And ISDN needs to bring the merger
of these two industries together very quickly. ISDN is causing a tighter
coupling, tighter integration -- particularly with the integration of voice
and data -- making computers and telecommunications come together faster.
But as we all know -- there are barriers we face. In March 1988, I gave a
speech for an ISDN User's Group here in Atlanta on "Removing the Barriers to
ISDN." I am sure that many of you have heard or have made a similar speech:
All of us must work to overcome the barriers, from those in the industry who
provide the service and equipment to the customers who use the service and
buy the products. It is our job to motivate the customers.
ISDN is being limited. Limited by service availability, the regulatory
environment, tariffs, incompatibility between products, complexity of
provisioning and installation, and knowledge about deployment -- just to name
a few of the barriers. Deployment plans and capital budget are crucial
elements that throttle the retooling of the telephone company workforce.
Service providers must rethink the way they develop and deploy technology.
If they want to play an increasing role in the rapidly growing data market,
the telephone companies will learn to think of central offices as "data
centers."
CPE vendors must evaluate and revise the way they develop and provide
equipment to users, as well as the way the applications get implemented to
use the service.
And as we begin to break down these barriers we must focus on our customers'
needs, keeping in mind the person who has to make the decision to buy the
service and equipment. We must offer the service and products that make
communications more efficient and cost effective, and that give the user a
competitive advantage in his business.
But, how can we expect a customer to implement ISDN today? We make it
difficult for the MIS Manager or Telecommunications Manager to buy the
service and our products. An MIS Director cannot plan a nation-wide or
global network for their company because he cannot easily determine where
service is available now -- and more importantly when service will be
deployed during his planning horizon. And, there is no direct single place to
go to find the answer. Very few user companies are US-based only. And
certainly very few companies are based only in one service area. So an MIS
Director is faced with going to a multitude of sources to collect data just
to evaluate if ISDN is a viable technology for an important application and
no one can tell him where to find all the needed information.
People in the communications business must communicate and share information.
With the two industries working together we can leverage our technical
expertise to benefit our customers.
ISDN is technically successful and working today even though improvements
will be made as standards evolve. What is needed now is the ability for
cooperative competition to allow the successful commercialization in the
North American markets. Customer needs can be met by cooperative behavior
between competitors which will remove real or perceived barriers that the
customer faces.
The Japanese understand cooperative competition. Look at the development of
the VHS tape player. The modem industry understands cooperative competition.
The development of CCITT V.42bis is an example of cooperative competition,
where companies worked together to offer the public the best technical
solution for compression in modems.
It is time to ask our legal departments how we can work together rather than
allowing them to say that we can't. There are areas such as standards,
sharing information with customers, and removing the barriers where we can
legally work together without crossing the line into areas where we compete
for business.
ISDN commercialization takes a great deal of team work from all of us:
Service Providers; Switch Vendors; CPE Vendors; Applications Developers;
Resellers. And, we must always be focusing on the end user and their needs.
Our goal as an industry should be to provide total customer satisfaction --
which will mean offering a range of solutions.
Some of the visionary people in the two industries believe that fiber optics
and broadband ISDN are the future. Basic Rate Access (BRA) and Primary Rate
Access (PRA) have their places. BRA can offer a range of applications that
can create the desktop telecomputing environment that starts the shift from
the paper-based office to one that is electronically-based.
Today the Xerox copier and the fax machine support the paper-based office.
Basic Rate ISDN is the technology which can initiate a wide-area change in
multiple locations and to electronic-based communications.
Trends show that businesses are changing. They need to be more competitive
in the global marketplace. They require a shorter cycle time from decision
making to implementation and they can no longer act as a single unit. A
business must work together with multiple enterprises. ISDN can be a major
catalyst that transforms businesses today and brings people into the
equation.
I believe that the integrated services and performance of ISDN will
fundamentally change the way people and businesses communicate. ISDN is not
a faster modem. It is not a "nicer" telephone. It is not easier wide-area,
dial-up switched 56K digital circuit and packet communications. It is the
combination of these things offered economically, worldwide, that are the
ingredients for an "office revolution" and a new market for all of our
industries.
ISDN can fuel the transition to an electronically-based office. Things are
happening in the computer industry -- large screen workstations from
companies such as Sun, HP, DEC, Apple and IBM. Applications like IBM Office
Vision, AT&T's Rhapsody, and Lotus Notes. Workstations are no longer for
"data" processing -- they are for information processing and with the
integration of voice and data, information processing can be brought to a
new level of interaction between the people who make decisions and take
action based on the information.
I am sure when the copier was first developed, no one imagined how businesses
would change -- with the ability of the printing press at their immediate
disposal. We in the ISDN industry can just begin to think about what can
happen with true multimedia integration. With voice and data integration,
people will be able to work on documents together -- no matter where they are
located.
Much of my company's focus has been on developing products that provide the
platform for good integration of voice and data --- not just products for
voice -- or products for data.
And, we realize the importance of applications developers, the people who
understand how work is done in an insurance company, a transportation
company, a retailer, or manufacturing company. These are the people that
have to drive the implementation of applications for the end user and can
assist us in exploring the integration of voice and data. We need those
people who understand the way businesses work to develop the applications
needed by real users who don't yet know how multimedia integration can change
their ability to get work done.
We have developed PC adapters for the computer to work with the service and
we have focused on the program interfaces (the Hayes Standard AT Command Set
for ISDN and the Hayes ISDNBIOS). These interfaces give applications
developers a platform to write their programs and provide the connection
between the CPE and the computer.
We strongly believe that it is the applications that will make customers want
to use any service. ISDN will be successfully implemented only when our
customers perceive it as faster and better, and offering improved price
performance and giving them some real advantage over their existing telecom
and datacom solutions. ISDN must allow our customers to meet their needs of
today but also allow them to take a large step forward in doing difficult
tasks more easily. ISDN must provide reasonably priced applications that are
not readily available today with alternative or bypass communications
solutions.
Our challenge is to bring our two industries together and to make ISDN
happen. To remove the barriers. Don't just create another spike of
expectation and excitement.
This afternoon the computer industry has an incredible opportunity -- the
opportunity to work together with the telecommunications industry to make
ISDN happen. For CPE vendors, applications developers, switch manufacturers
and telecommunications service providers to work together to launch a new
technology which will bring competitive advantage to our North American
customers, and fulfill user needs for easily accessed, integrated, efficient,
and cost effective integrated communications.
A simple concept: customers and suppliers working together letting each
other know what they need to make something happen.
Bellcore has given both industries this workshop to begin the talks and to
open the lines of discussion between the two industries. And, going forward,
they will continue to play this role through their Resource Personnel.
Together the two industries can make ISDN a reality.
Just as we heard for six or seven years "This is the year of the LAN"
announced by our or another of the LAN company's CEO's, there were six or
seven years of the LAN leading to the success we see today. Today's LAN is
an important business tool.
If we grasp the opportunity Bellcore has given the industry here today on top
of all that is already being done throughout the industry, then surely we
will be able to look back and say 1991 was the first year we claim "This is
the year of ISDN."

== Human Speech Understanding ==
== GTE Project 426 ==
Research in Project 426 focused on areas of human speech understanding and
cognitive psychology that are critical to introducing automation in telephone
operations, and to designing effective human-computer interfaces. In
addition, substantial support was provided to GTE Airfone, and research was
also directed at understanding how factors associated with wireless
communication (e.g., time delays, low-bit-rate speech coders, various channel
impairments) can influence conversations.
In 1990, Project 426 continued to support Project 533 (Application of
Automatic Speech Recognition to Telephone Operations) by providing
information on the characteristics of calls to Customer Service Order Centers
(CSOCs). Project staff completed analysis of a large set of conversations
have been cataloged on a variety of dimensions. Based on the information in
the database, a report was prepared on automating customer service contacts
by means of computer-based speech recognition. In addition, work has started
on characterizing vocabulary in different types of conversations (e.g.,
orders to install versus disconnect service) via automatic indexing and
cluster analysis.
To support detailed analysis of these recorded conversations, the VAX speech
editor was rewritten using a C++ style object-oriented user interface. A
study to analyze the timing of question-answer sequences between CSOC
representatives and customers is now under way.
The long-term issues pertinent to the development of speech-based automated
systems were addressed in a paper presented at an international conference.
Topics discussed included methods for measuring the complexity of dialogue,
convergence (the process by which conversant adopt aspect of each others
speech), and the use of dialogue control acts (extra conversational steps
that ensure that the conversation proceeds smoothly).
Project staff also completed a report on an experiment performed in 1989 that
was designed to investigate the effects of attentional constraints on the
processing of natural and synthetic speech.
In 1990, work continued on evaluating conversations recorded under controlled
conditions that simulated one or more factors found in mobile
telecommunication systems. A new test procedure designed in 1989 was
refined, and measurement techniques were developed. Using this new
procedure,
an experiment to investigate conversation dynamics over delay circuits with
600 and 1200 ms lags was completed. Resolving the delay question is an
important first step in the project's investigations of conversation dynamics
in wireless channels because speech-compression techniques can introduce a
delay on the order of 150 ms (delays due to switching or transmission may add
significantly to this figure). The project team is now in the process of
testing subjects in a second study that includes speech coder/bit error
conditions using the two-way ASET board developed by the Speech Technology
Group.
Work in support of the second-generation Airfone system focused on the design
and operation of Seatfone ][. In 1990, project staff completed a series of
experiments and reports, including a study on user preference for membrane
keypads, a study of dialing performance using membrane keypads under
different feedback conditions (both auditory and visual), an assessment of a
new Seatfone handset, detailed comments and suggestions on a set of flow
charts intended to illustrate the call-sequence logic of Seatfone ][, and a
report on the quality of new speech prompts. In addition, work has now
started on a comprehensive evaluation of the Seatfone ][ design using a
prototype developed by Airfone and ASIC Designs, and on the preparation of
detailed user-interface specifications.

This Phile is hopefully the first in a series of Philes on VMB's. This is
also dedicated to Night Stalker (.aka. Flt 255 of (313) in memory of..) , and
all the fellows at NSA and Disconnected, including but not limited to those
who have helped, Dark Druid, I-Shence-Master, Mind Rape, A.O.D., Dead Addict
and Mommie Dearest.
I would like to add that all this information contained here within is not
intended to cause, direct or in any means relate to any illegal activities. I
can also say the following is true.
Title 18 of the United States Code, Section 1030, (Revised 1986) gives the
Secret Service, among other Federal law enforcement agencies, the right to
investigate fraud and related activities in connection with "Federal-Interest
computers."
---------------------------------------------------------------------------
- The above is true and the information below is for educational purposes -
- only. Plus the information should be free to all! -
===========================================================================
8.8.91 VMB Number 1.00 A Info Series on 800.xxx.6245 MAIL Scans
===========================================================================
The purpose of this Phile was to Scan the 800.xxx6245, where xxx is all the
possible prefixes. 6245 represents MAIL on DMTF fones. So I realized that
many
people would take the time to check out this sub-prefix, 6245. I have done
all the initial information scanning and did not try to invade these systems.
I hope this information will help you to better understand VMB's. Heck if you
don't know what a VMB is you should do a little research. I believe LOL #10
or
12 is on VMB's. I will however cover some basics.
VMB - stands for Voice Mail(Message) Box, this is a voice message system,
that allows messages, call transfers. ect. - Most work on a 3 or 4
digit mail box and an associated password to access that box.
The problem is alot of systems are getting security wacko and have Password,
then Box or 8 digit boxes and 8 digits Passwords combos. This phile is not
meant for you to hack these numbers but just as an informational source. As
an Anarchist or CyberPhreak you can appreciate the wealth of this
information. These Corporations generally do not take the time to listen. I
really doubt if they even use there VMB's, however if you have a gripe leave
a message to those concerned.
========================================================================
-------- Doing The VMB Shuffle or How to spend a Summer Day -----------
------------------------------------------------------------------------
[A] FH (Fuckin Hacker) 2.0 - Modifications and Setups that were used.
[1] Main Menu , Type D for Utilities
[2] Type A for Config Modem
Suggest putting ATL0 or ATL1 in your Modem Initialization string
to turn the speaker low.
[D] PBX Dialing - Turn to YES
[E] Outgoing Digit - Set to 1800
[I] Speaker - ON
[3] Go to the Target and Valid files and leave only one entry, you can
delete all the entries, it will leave one that is set at default
values.
[4] Go next to EDIT EXTENDERS
Remember this is a VMB run so you need no extenders, but will Add
new ones. Choose ADD.
[A] None leave blank
[B] None leave blank - The PBX option in the config modem takes
care of the outdial digits.
[C] Leave at Local
[D] Adjust to your board or leave as defaults.
[E] Adjust to your board or leave as defaults
[F] leave off
[G] Answer Delay - set to 0
[H] Target Delay - set to 35 or more
[I] 0
[J] Code First - YES
[K] Sequential - I use sequential so I can watch when the cycle
ends and ESC back and flag ones that completed
off or read just the scan to the next prefix
series.
[L] Code Length - 7
[M] Code Template - ##abbbb where ## is the Digit Cycle, a is
the change cycle and bbbb in this case was
6245. (Mail). I use a random scan search for
example I know that the first two digits of
a prefix cannot be 1 or 2 and the third
cannot be 0, so I set up my ADDs in a random
number sequence to cover the numbers from 2
to 9, ie. 8,2,9,5,7,3,6,4 so the first
template is 82X6245 then 22X6245 then
92X6245. The X is important since this is
what changes from scan to scan. FH doesn't
go in order and may hit an code sequence two
or three times so you may hit an prefix once
every 15 dials.
[N] Starting Code - ##abbbb where # is your starting number ie
82, a is always 1 on the initial pass and increases, bbbb in
this case is 6245.
All other values I leave at default, once I have added the
prefixes, I go to the extender flagging and flag them all.
[5] Flag Extenders - flag all your additions
[6] ESC and start HACKING from the main menu. I may add that I
created a batch file that would random hack and wait for 5 - 15
minutes both ways. Do not spend 8 hours or even more than 30
minutes Scanning even if you have alot of Ports, running.
------------------ FH VMB Hints and Thins to Watch For. ---------------
[B] Pay Attention here. Alot of people miss these hints, they will
save you time and will even force you to listen durin scanning.
You hear a click before the ringing, this is 99% a invalid
prefix, prepare to hit the SpaceBar to skip this prefix.
You here a dial tone, hey this may be a PBX, let us know! If
you hear some DMFT tones then another ringing, this may be a
Diverter.
You get a message to leave a message, Hit * or # if it
continues wait for a double beep. This can be a diverter or a
backdoor into a PBX or you can just playback the messages or
other stuff.
You get a Carrier, fast hit spacebar record the number. In
the setup I have provided FH may error out because of no Code
File stated. Check the Carrier later.
VMBing works best at night, after business hours, since most
companies have operators during the day, and you will miss
and piss off people during the daytime.
Be careful of the MCI/US Sprint lines, they have Level D ANI
and see a display of who called. If they have CA (Call
Accounting) then they have a record of your number on a
printout (Sweep Finder).
Most Passwords can be the box number or an variation,
for boxes try either 999,9999,1000 or 1111 these are
generally the default Telco administrator boxes.
These are just a few notes...Now for the Good stuff. Remember, These
numbers are current as of 8.8.91 so they are fresh, don't burn them
out. If you do get a Slave going let me know. If there are any
additions or comments let me know. (See end of Phile to contact me)

Well, there's 70 VMB's for yah. These are just the .6245.'s believe me there
are a couple of hundred if not thousand more out there. If you get a slave
box, do us a favor...share your information.
This concludes the first in a series of VMB information. I hope in the future
to provide some more radical technical information..i.e. Interfacing VMB's
with PBX's and how it all works, Technical DoX on Major VMB's and maybe
develop a Scan Klub. Hope you have phun, but do remember if you have a Gripe
tell it to the President of the Company...LEAVE A MESSAGE IN THE VMB!

That is what The Serious Side of Hacking is all about. Poetic hackers are
perhaps one of the most neglected minorities in the country. Looking on a
list of possible scholarships, I see "Homosexual, Blind, Black Agraphobes",
but no poetic hacker. Lets face it, society just ignores us. Fellow hackers
just ignore us. No more. Now we have an entire dedicated section in the
most prestigious hacking newsletter (that has my name on it) ever produced.
Now, why me, why not our capable editor Mind Rape? Very good question... I
was going to let him write this section... Then I heard some of his poetry.
I handle this section now. (offence intended, Mind Rape). However, this is
not only a poets forum, we also support many other neglected hacker topics.
What topics you say? Lotsa topics.... Previously unreleased boxes, cool
anarchy techniques, and much, much, more.
Mind Rape wanted to call this area "Hacker Sarcasm". I said "ikes, that
sucks, Mind Rape". But we tried to keep a humoristic view about it, and
hopefully there will be a pinch of humor in all of this writing.
Where to complain if you do not like any of this: fuck you, go to hell,
lemme see you do better, you uncreative, unapreciative louse. (wow, that's
pretty cool word too - "louse")
Unclaimers, Reclaimers, Disclaimers, Recliners - I hereby claim every hacking
technique ever to be discussed here WORKS. I don't know what the word
RECLAIMERs means. The only DISCLAIMER this section has is that we take no
responsibility for the MANY crimes we hope to encourage you, and your friends
to commit. RECLINERS, great to laze around in.
Ok, kids, that looks like about it for now.... enjoy the TSSOH articles
contained herein (wow, what a cool word!), and Mind Rape, I sure hope to hell
you don't want me to write an introduction EVERY issue. (see definition of
RECLINER for my reasons for this request).

== The INVISIBLE Box ==
==The first in a series of previously unreleased boxes==
An Introduction
A friend of mine who is both an electrician and a phone technician has had no
contact with the computer underground, and yet has managed to design and
produce several incredible boxes that never have been released. This dear
soul was kind enough to take me under his wing and show me some of his
incredible inventions. Luckily for all of us he was not only interested in
saving some money (he too abhors the idea of paying for ANY phone call), but
had a healthy interest in anarchy as well. The INVISIBLE box I am about to
describe is SO incredible it makes the blotto box look like the DONUTHIN box
(to be released at a later time in this series).
DISCLAIMER: Important! This file was DESIGNED to ENCOURAGE others to break
laws, commit anarchy, and create havoc. If you have NO intention
of doing all of the above please do NOT read this. I however
will take NO responsibility for the MANY laws I hope I to
encourage you to break.
USAGE:
Essentially this is an improved blotto box. But the blotto box, as we know
was bullshit, this WORKS! (I have, um, er, friends that have told me so, I
would NEVER break any laws myself). Through the use of the RS232 port on
your 50mhz IBM compatible we will show you how to destroy ANY, I repeat ANY
area code you wish to destroy. I know this sounds incredulous but there is
an essential flaw in the surge protect system that is installed around the
country. (This system is the reason that the blotto box did not work and
was bullshit). One of the incredible features that this box has is that it
is IMPOSSIBLE to trace with existing current technology.
WHAT MAKES THIS BOX POSSIBLE:
The flaw with the infamous blotto box is that it tried to instantly fry the
area code (another flaw is that it tried to kill the area code that you were
IN). The INVISIBLE box slowly builds up voltage in the remote target until
the required voltage is established, then discharches just enough voltage to
create a spike to demolish an area code.
MATERIALS NEEDED:
Honda Generator:
Note: (hey, WOW, they DID get SOMETHING right on that blotto
bullshit)
How to obtain: Rent (this costs a bit, so stay with me)
Steal! (preferred method)
486 50mhz IBM Compatible: Why all this power? One of the reasons that this
has not been done before is that there is not
enough speed to properly kill off area codes with a
wimply 486 25mhz, so we have to use a 50mhz
machine.
How to obtain: Again, NSA STRONGLY recommends that you steal one
of these. (the chair-through-the-window-technique
is suggested).
!!!MOST IMPORTANT!!!!
The National Security Anarchists Release Of
"Area Sucking, Smashing Heroific Osculator: Lancaster Engineered"
I know the title is a bit of a mouthful, but the writer of the program (my
friend I was telling you about) insisted, so NSA finally gave in, and
released it under that name. This program has already been released to the
general public, and can be found on ANY worthwhile H/P/A/C/V/K/W board in the
country.
The interface between the components has been explained in detail with the
docs to that accompany the program. (we tried to think of an acronym for the
program, but were at a loss).
Well I guess thats pretty much it. I would explain how to use the program,
but it is SO painfully obvious once you load it in, I would feel like an
idiot spending precious disk space explaining it here.
NOTES: I would like to thank my friend (Lancaster) for thoughtfully
engineering this, and taking the time and energy to write the program
(he spent four LONG months doing so). I would also like to announce
with pride that this program is now Windows compatible, and soon will
be released for various other systems depending on the hardware that
is currently available on some systems. Thank you, and happy area
code killing.

We at NSA, decided that World News and Telco Briefs are basicly the same idea
divided up into two sections. Therefore resulting in the mixture of both,
Info World. This is where one can develop a good source of knowledge of
Teleco/Hacker Information. Here, one can see what new advancements have
taken place/problems have happened in the Teleco/Hacker World. Also one can
see and theorize how Ma Bell can use her new technology to destroy us. Even
if the idea is petty, but expand on that idea. We do tell you our views so
that hopefully Hackers/Phreakers will develop their own, be able to create
their own views/theories. To create that realization for him/herself, which
then creates a better understand of our Society and yourself. Do you limit

== PAC Bell, NEC Sign SMDR Pact ==
== Telephony ==
-------------------------------------
Pacific Bell has inked an agreement to market NEC Technologies' Centrex-based
station message detail recording (SMDR) and call accounting equipment to it's
California Centrex customers.
The additional products are expected to help make Pacific Bell's Centrex
offering more attractive and competitive with customer premises-based network
solutions.
The NEC gear, known as Centrex Telemanagement, lets telecos offer call
accounting, traffic management, automated directory, facilities management,
and equipment and feature inventory through the central office. The
equipment can interface with AT&Ts 5ESS and 1AESS switches, Northern
Telecom's DMS-100, and NEC's own equipment, according to Susan Schneider,
product marketing specialist with Boxborough, Mass. based NEC Technologies.
-----------------------------------
== MCI Readies Data Platform ==
== Telephony ==
-----------------------------------
MCI has unveiled the platform that will bring its Virtual Private Data
Services (VPDS) into the future, as well as the first offering via platform:
a frame relay service.
At the International Communication Association show in Anaheim, California,
in the first week of June. MCI unveiled plans to deploy a nationwide,
cell-based network platform to support next generation broadband data
services under its VPDS umbrella. The first service offered on the platform,
frame relay, will be available in the second quarter of 1992., according to
Don Heath, MCI vice president for data marketing. The network also offers a
migration path to future services, including switched multimegabit data
service and asynchronous transfer mod-based broadband integrated services
digital network, he said.
"What MCI is offering is a clear migration path to tomorrow's communications
networks," Heath said. "We're opening the door to make broadband ISDN
services a reality."
The broadband platform will be cell-based, using 53-byte, fixed-sized data
packets. Initially, MCI will offer the data services on permanent virtual
circuits. Later, MCI will offer switched virtual circuits, which will
permit direct dial-up network with ISDN primary rate interface access.
Network access will be offered at 56Kb/s, fractional T-1 and T-1 speeds;
the backbone will operate at full T-1.
----------------------------------------
== AT&T Previews New Marine Cable ==
== Telephony ==
----------------------------------------
AT&T Submarine Systems will introduce a new undersea cable product line at
Telecom '91 in Geneva this October, the company said at the beginning of
June. Known now as the SL2000 cable system, the product will be renamed, and
a prototype exhibit will be on display at the show.
Although AT&T will design, install and maintain the system, the company has
been working with Kokusal Denshin Denwa of Japan for the past year to develop
optical amplifier technology for the SL2000 according to Debra Guancione,
product manager for AT&T Submarine Systems.
Current underseas systems require repeaters every 20 mile to 60 miles.
AT&T hopes to reach beyond 60 miles by the time the product becomes
available for service in 1995.
The cable system will package together bit rate-sensitive terminal equipment,
dispersion-shifted fiber, optically amplified repeaters and cable, all
configured according to customer requirements. It will offer rates of 5
Gb/s, 25 Gb/s or 622 Mb/s per fiber pair.
-----------------------------------
== Motorola and Pactel Trial ==
== Telephony ==
-----------------------------------
Motorola and PacTel Corporation will conduct field tests and market trails of
Code Division Multiple Access (CDMA) digital cellular technology. The trials
will take place in PacTel Cellular's Southern California service area. The
agreement follows more than a year and a half of CDMA testing already
conducted by the two companies. Among the activities planned for the trial
is the validation of Common Air Interface (CAI) specification. CDMA and TDMA
represent two competing technologies designed for migrating cellular systems
to a digital standard and increasing subscriber capacity.
--------------------------------
== Teleport Opts for ISDN ==
== Telephony ==
--------------------------------
TC Systems, a subsidiary of the Telport Communications Group, is now
providing local ISDN connectivity for Manhattan-based customers that need to
maintain ISDN links with both Europe and the far Esat. The first customer to
sign up for the new service is banking giant Citicorp, who will use it to
establish connections with London, Brussels, Dusseldorf, and Singapore. TC
Systems also operates one of the nations' largest ISDN "islands" consisting
of over 6000 BRI liens, currently being used by its parent company Merill
Lynch.

------------------------------------
New York Telephone is reorganizing along geographical lines, it disclosed
Friday. The goal is to bring services, "closer to our customers," a
spokesman said, but gave no exact date for full implementation of the new
organization.
The reorganization creates three geographic market areas, each under a group
vice president, Douglas Mello, previously president of Nynex Business
Information Systems, will be responsible for midtown and southern Manhattan
and for the company's special data services for its top 200 accounts. Arnold
Eckelman, former assistant vice president-operations, will be responsible for
norther Manhattan, the Bronx, Brooklyn, Queens and Staten Island. Particia
Higgins, formerly AT&T's vice president for international sales operations,
will head the company's Long Island, mid-state and upstate New York
operations.
The decentralization is necessary to respond to "enormous" changes in the
telecommunications marketplace, including increased competition, said Richard
Jalkut, president and CEO. The new organizations "will give us the
flexibility we need to respond to these changes," he said.

== San Bernerdino Outage ==
== Internal GTE/AGCS Document ==
------------------------------------
On 6/19/91 at 7:34 P.M. San Bernardino, Ca. which serves 55,000 subscribers
experienced a 2 hour and 9 minute outage. This outage was caused by a fault
in the Space Switch Interface Controller (SIC). The SIC is the interface
between the APC/TPC's and the Space Switch portion of the Base Unit Network.
Without the SIC no call processing can take place since no network paths can
be established. The SIC portion of the GTD-5 is a duplex device and should
not cause a total outage. However, under certain double fault or backplane
fault conditions a duplex device can cause system outages.
San Bernardino has had a history of SIC problems, but none that had caused a
problem of this magnitude. During early 1990 West Area personal worked on
the SIC - and no problems were reported for 8 months.
Beginning 6/21/91 (after the latest outage) I have been working with AGCS and
West Area TSS personnel to resolve this problem. AGCS TAC and R&D personnel
were dispatched to the site to work with local personal on Saturday and
Sunday nights (6/22 and 6/23) to try and isolate the problem. While using a
scope to monitor certain suspect leads, a SMA syndrome similar to the
syndromes output during previous problems was output. No outage occurred.
Based upon this SMA being output when the pin was touched, a decision was
made to replace on of the wires that appeared to be very tight and could
possibly have "worn through" insulated or could have been pulling against
another pin. After replacing the wire AGCS and TSS personnel could not cause
the syndrome to be generated.
On 6/24/91 we held a meeting to assess the progress in resolving the problem.
At that time we could not get more than a 70 percent comfort level that the
fault that had caused the outage had been cleared by replacing the wire.
Inspection of the wire under a microscope has not displayed any flaws.
Based upon the risk that another outage could occur, TSS west and myself have
recommended that the SIC backplane be replaced as soon as possible. AGCS is
currently procuring the backplane. A decision has been made to use a roll
around/portable frame to house a temporary SIC while the backplane is being
replaced. The same concept used for the SVR 1641 16 Port BPC retrofit will
be used in San Bernardino to replace the SIC backplane. This process will
minimize the outage time caused by the changeout.
