    16. What is a CNA number?



CNA stands for Customer Name and Address. The CNA number is a phone
number for telephone company personnel to call and get the name and
address for a phone number. If a telephone lineman finds a phone line
he does not recognize, he can use the ANI number to find its phone
number and then call the CNA operator to see who owns it and where
they live.

Normal CNA numbers are available only to telephone company personnel.
Private citizens may legally get CNA information from private
companies. Two such companies are:

Unidirectory (900)933-3330
Telename (900)884-1212

Note that these are 900 numbers, and will cost you approximately one
dollar per minute.

If you are in 312 or 708, AmeriTech has a pay-for-play CNA service
available to the general public. The number is 796-9600. The cost is
$.35/call and can look up two numbers per call.

If you are in 415, Pacific Bell offers a public access CNL service at
(415)705-9299.

If you are in Bell Atlantic territory you can call (201)555-5454 or
(908)555-5454 for automated CNA information. The cost is $.50/call.

    22. What is scanning?



Scanning is dialing a large number of telephone numbers in the hope
of finding interesting carriers (computers) or tones.

Scanning can be done by hand, although dialing several thousand
telephone numbers by hand is extremely boring and takes a long time.

Much better is to use a scanning program, sometimes called a war
dialer or a demon dialer. Currently, the best war dialer available to
PC-DOS users is ToneLoc from Minor Threat and Mucho Maas. ToneLoc can
be ftp'd from ftp.paranoia.com /pub/toneloc/.

A war dialer will dial a range of numbers and log what it finds at
each number. You can then only dial up the numbers that the war
dialer marked as carriers or tones.


    23. Is scanning illegal?



Excerpt from: 2600, Spring 1990, Page 27:

-BQ-
In some places, scanning has been made illegal. It would be hard,
though, for someone to file a complaint against you for scanning since
the whole purpose is to call every number once and only once. It's
not likely to be thought of as harassment by anyone who gets a single
phone call from a scanning computer. Some central offices have been
known to react strangely when people start scanning. Sometimes you're
unable to get a dialtone for hours after you start scanning. But
there is no uniform policy. The best thing to do is to first find out
if you've got some crazy law saying you can't do it. If, as is
likely, there is no such law, the only way to find out what happens is
to give it a try.
-EQ-

It should be noted that a law making scanning illegal was recently
passed in Colorado Springs, CO. It is now illegal to place a call
in Colorado Springs without the intent to communicate.

Notes:

[C1] - Means code used for Cellular One service
[1] - for cellular in Pittsburgh, PA A/C 412 in some areas
[2] - indicates that you are not local and maybe how to reach you
[3] - found in Pac Bell territory; Intercom ring causes a distinctive
ring to be generated on the current line; Hold keeps a call
connected until another extension is picked up
[4] - applied once before each call
[5] - A.C.R. blocks calls from those who blocked Caller ID
(used in C&P territory, for instance)
[6] - cancels further return attempts
[7] - *82 (1182) has been mandated to be the nationwide code for
"Send CLID info regardless of the default setting on this
phone line."
[M: *xx] - alternate code used for MLVP (multi-line variety package)
by Bellcore. It goes by different names in different RBOCs.
In Bellsouth it is called Prestige. It is an arrangement of
ESSEX like features for single or small multiple line groups.

The reason for different codes for some features in MLVP is that
call-pickup is *8 in MLVP so all *8x codes are reassigned *5x

    29. What is Caller-ID?



This FAQ answer is stolen from Rockwell:

Calling Number Delivery (CND), better known as Caller ID, is a
telephone service intended for residential and small business
customers. It allows the called Customer Premises Equipment (CPE) to
receive a calling party's directory number and the date and time of
the call during the first 4 second silent interval in the ringing
cycle.

Parameters
~~~~~~~~~~
The data signalling interface has the following characteristics:

Link Type: 2-wire, simplex
Transmission Scheme: Analog, phase-coherent FSK
Logical 1 (mark) 1200 +/- 12 Hz
Logical 0 (space) 2200 +/- 22 Hz
Transmission Rate: 1200 bps
Transmission Level: 13.5 +/- dBm into 900 ohm load


Protocol
~~~~~~~~
The protocol uses 8-bit data words (bytes), each bounded by a start
bit and a stop bit. The CND message uses the Single Data Message
format shown below.

| Channel | Carrier | Message | Message | Data | Checksum |
| Seizure | Signal | Type | Length | Word(s) | Word |
| Signal | | Word | Word | | |

Channel Seizure Signal
~~~~~~~~~~~~~~~~~~~~~~
The channel seizure is 30 continuous bytes of 55h (01010101) providing
a detectable alternating function to the CPE (i.e. the modem data
pump).

Carrier Signal
~~~~~~~~~~~~~~
The carrier signal consists of 130 +/- 25 mS of mark (1200 Hz) to
condition the receiver for data.

Message Type Word
~~~~~~~~~~~~~~~~~
The message type word indicates the service and capability associated
with the data message. The message type word for CND is 04h
(00000100).

Message Length Word
~~~~~~~~~~~~~~~~~~~
The message length word specifies the total number of data words to
follow.

Data Words
~~~~~~~~~~
The data words are encoded in ASCII and represent the following
information:

o The first two words represent the month
o The next two words represent the day of the month
o The next two words represent the hour in local military time
o The next two words represent the minute after the hour
o The calling party's directory number is represented by the
remaining words in the data word field

If the calling party's directory number is not available to the
terminating central office, the data word field contains an ASCII "O".
If the calling party invokes the privacy capability, the data word
field contains an ASCII "P".

Checksum Word
~~~~~~~~~~~~~
The Checksum Word contains the twos complement of the modulo 256 sum
of the other words in the data message (i.e., message type, message
length, and data words). The receiving equipment may calculate the
modulo 256 sum of the received words and add this sum to the received
checksum word. A result of zero generally indicates that the message
was correctly received. Message retransmission is not supported.

Example CNS Single Data Message
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
An example of a received CND message, beginning with the message type
word, follows:

04 12 30 39 33 30 31 32 32 34 36 30 39 35 35 35 31 32 31 32 51

04h= Calling number delivery information code (message type word)
12h= 18 decimal; Number of data words (date,time, and directory
number words)
ASCII 30,39= 09; September
ASCII 33,30= 30; 30th day
ASCII 31,32= 12; 12:00 PM
ASCII 32,34= 24; 24 minutes (i.e., 12:24 PM)
ASCII 36,30,39,35,35,35,31,32,31,32= (609) 555-1212; calling
party's directory number
51h= Checksum Word

Data Access Arrangement (DAA) Requirements
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To receive CND information, the modem monitors the phone line between
the first and second ring bursts without causing the DAA to go off
hook in the conventional sense, which would inhibit the transmission
of CND by the local central office. A simple modification to an
existing DAA circuit easily accomplishes the task.

Modem Requirements
~~~~~~~~~~~~~~~~~~
Although the data signalling interface parameters match those of a
Bell 202 modem, the receiving CPE need not be a Bell 202 modem. A
V.23 1200 bps modem receiver may be used to demodulate the Bell 202
signal. The ring indicate bit (RI) may be used on a modem to indicate
when to monitor the phone line for CND information. After the RI bit
sets, indicating the first ring burst, the host waits for the RI bit
to reset. The host then configures the modem to monitor the phone
line for CND information.

Signalling
~~~~~~~~~~
According to Bellcore specifications, CND signalling starts as early
as 300 mS after the first ring burst and ends at least 475 mS before
the second ring burst

Applications
~~~~~~~~~~~~
Once CND information is received the user may process the information
in a number of ways.

1. The date, time, and calling party's directory number can be
displayed.

2. Using a look-up table, the calling party's directory number can be
correlated with his or her name and the name displayed.

3. CND information can also be used in additional ways such as for:

a. Bulletin board applications
b. Black-listing applications
c. Keeping logs of system user calls, or
d. Implementing a telemarketing data base

    30. How do I block Caller-ID?



Always test as much as possible before relying on any method of blocking
Caller-ID. Some of these methods work in some areas, but not in others.

Dial *67 before you dial the number. (141 in the United Kingdom)
Dial your local TelCo and have them add Caller-ID block to your line.
Dial the 0 Operator and have him or her place the call for you.
Dial the call using a pre-paid phone card.
Dial through Security Consultants at (900)PREVENT for U.S. calls
($1.99/minute) or (900)STONEWALL for international calls ($3.99/minute).
Dial from a pay phone. :-)


    31. What is a PBX?



A PBX is a Private Branch Exchange. A PBX is a small telephone switch
owned by a company or organization. Let's say your company has a
thousand employees. Without a PBX, you would need a thousand phone
lines. However, only 10% of your employees are talking on the phone
at one time. What if you had a computer that automatically found an
outside line every time one of your employees picked up the telephone.
With this type of system, you could get by with only paying for one
hundred phone lines. This is a PBX.


    32. What is a VMB?



A VMB is a Voice Mail Box. A VMB is a computer that acts as an
answering machine for hundreds or thousands of users. Each user will
have their own Voice Mail Box on the system. Each mail box will have
a box number and a pass code.

Without a passcode, you will usually be able to leave messages to
users on the VMB system. With a passcode, you can read messages and
administer a mailbox. Often, mailboxes will exist that were created
by default or are no longer used. These mailboxes may be taken over
by guessing their passcode. Often the passcode will be the mailbox
number or a common number such as 1234.


    33. What are the ABCD tones for?



The ABCD tones are simply additional DTFM tones that may be used in any
way the standard (0-9) tones are used. The ABCD tones are used in the
U.S. military telephone network (AutoVon), in some Automatic Call
Distributor (ACD) systems, for control messages in some PBX systems, and
in some amateur radio auto-patches.

In the AutoVon network, special telephones are equipped with ABCD keys.
The ABCD keys are defined as such:

A - Flash
B - Flash override priority
C - Priority communication
D - Priority override

Using a built-in maintenance mode of the Automatic Call Distributor
(ACD) systems once used by Directory Assistance operators, you could
connect two callers together.

The purpose of the Silver Box is to create the ABCD tones.

See also "What are the DTMF Frequencies?"


    34. What are the International Direct Numbers?



The numbers are used so that you may connect to an operator from a
foreign telephone network, without incurring long distance charges.
These numbers may be useful in blue boxing, as many countries still have
older switching equipment in use.

    * Section C: Cellular *


~~~~~~~~~~~~~~~~~~~

    01. What is an MTSO?



MTSO stands for Mobile Telephone Switching Office. The MTSO is the
switching office that connects all of the individual cell towers to the
Central Office (CO).

The MTSO is responsible for monitoring the relative signal strength of
your cellular phone as reported by each of the cell towers, and
switching your conversation to the cell tower which will give you the
best possible reception.


    02. What is a NAM?



NAM stands for Number Assignment Module. The NAM is the EPROM that
holds information such as the MIN and SIDH. Cellular fraud is committed
by modifying the information stored in this component.


    03. What is an ESN?



ESN stands for Electronic Serial Number. The is the serial number of
your cellular telephone.


    04. What is an MIN?



MIN stands for Mobile Identification Number. This is the phone number
of the cellular telephone.


    05. What is a SCM?



SCM stands for Station Class Mark. The SCM is a 4 bit number which
holds three different pieces of information. Your cellular telephone
transmits this information (and more) to the cell tower. Bit 1 of the
SCM tells the cell tower whether your cellphone uses the older 666
channel cellular system, or the newer 832 channel cellular system. The
expansion to 832 channels occured in 1988. Bit 2 tells the cellular
system whether your cellular telephone is a mobile unit or a voice
activated cellular telephone. Bit's 3 and 4 tell the cell tower what
power your cellular telephone should be transmitting on.

Bit 1: 0 == 666 channels
1 == 832 channels

Bit 2: 0 == Mobile cellular telephone
1 == Voice activated cellular telephone

Bit 3/4: 00 == 3.0 watts (Mobiles)
01 == 1.2 watts (Transportables)
10 == .06 watts (Portables)
11 == Reserved for future use


    06. What is a SIDH?



SIDH stands for System Identification for Home System. The SIDH in your
cellular telephone tells the cellular system what area your cellular
service originates from. This is used in roaming (making cellular calls
when in an area not served by your cellular provider).

Every geographical region has two SIDH codes, one for the wireline
carrier and one for the nonwireline carrier. These are the two
companies that are legally allowed to provide cellular telephone service
in that region. The wireline carrier is usually your local telephone
company, while the nonwireline carrier will be another company. The
SIDH for the wireline carrier is always an even number, while the SIDH
for the nonwireline carrier is always an odd number. The wireline
carrier is also known as the Side-B carrier and the non-wireline carrier
is also known as the Side-A carrier.


    07. What are the forward/reverse channels?



Forward channels are the frequencies the cell towers use to talk to your
cellular telephone. Reverse channels are the frequencies your cellular
telephone uses to talk to the cell towers.

The forward channel is usually 45 mhz above the reverse channel. For
example, if the reverse channel is at 824 mhz, the forward channel would
be at 869 mhz.
