                  CHAPTER TWO: SPECIAL BELL NUMBERS

     In chapter two we will explore the various special Bell #'s, 
such as:  CN/A, AT&T, NEWSLINES, LOOPS, 99XX #'S, ANI, RINGBACK, and 
a few others.

CN/A:
     CN/A, which stands for Customer Name and Address, are bureaus 
that exist so that authorized Bell employees can find out the name 
and address of any customer in the Bell system.  All numbers are 
maintained on file including unlisted numbers.
                        Here's how it works:
     1) You have a number and you want to find out who owns it.  For 
example, you know the number (914) 555-1234, and want to know whose 
number it is.
     2) You look up the CN/A number for that area code in the list 
below.  In the example, the area code is 914 and the CN/A number is 
518-471-8111.
     3)  You then call up the CN/A number (during business hours) and 
say something like, "Hi, this is John Jones from the residential 
service center in Miami.  Can I have the customer's name at 914-555-
1234.  That number is 914-555-1234."...make up your own real sounding 
name, though.
     4)  If you sound natural and cheery, the operator will ask no 
questions.

     Bell mainly uses these numbers listed below to find out who owns 
a number that a customer claims he never called.

NOTE:  The following is the most complete list of CN/A numbers in my 
possession.  This list was copywrited in 1982 by "Judas Gerard" as is 
originally appeared in TAP issue #78.

AT&T NEWSLINES:
     Newslines are recordings that Bell employees call up to find out 
the latest information about stock, technology, etc., concerning the 
Bell system.  Here are the currently known numbers:

                                LOOPS

     First, you must understand the concept of loops.  I think that 
the best way it can be explained is the way it was explained to me:
     "The Loop is a great alternative communication medium that has 
many potential uses that haven't been tapped yet.  Visualize two 
phone numbers (lines) just floating around in the Telco Central Of
fice (CO).  Now, if you and a friend were to call these two numbers 
at the same time, POOFF!  you are connected together.
     "What can you use it for?  Well, haven't you ever wanted someone 
to call you back, but been reluctant to give out your home phone 
number?  Or better yet, stumbling on a loop that has multi-user capa
bilities, for those late-night conferences.  Best of all, finding a 
non-supervised loop that doesn't charge any MSU's or tolls to one or 
both parties?"
     Here is how to find a loop:  First, remember to do all of your 
loop searching at night.  This is because loops serve a genuine test 
function during the day which Telco uses, and you don't want to run 
into an irate lineman now, do you.  To find a loop, having two num
bers is a definite plus.  If not, have a friend to dial numbers at 
his location.  As a last resort, try dialing from two adjacent pay 
phones.  Now get your trusty white pages, and turn to the page where 
it lists the numbers of MSU's from your exchange.  The idea is to 
find a loop that is within your primary calling area or is only one 
MSU in your area.  This is so you don't bankrupt trying to find a 
loop.  Write down all of these exchanges and do a 99XX scan of those 
exchanges (99XX scanning will be discussed shortly).
     Loops are found pairs which are usually close to each other.  
For example, in NPA 212, where the infamous loops are found, there is 
a standard loop format.

MANHATTAN & BRONX-------NNX-9977/9979
BROOKLYN & QUEENS-------NNX-9900/9906

     NXX is the exchange to be scanned.  Here are some loops that 
have been found in NYC.  These are sued mostly by phreaks and call-in 
lines for pirate radio stations:

212-220-9900/9906
212-283-9977/9979
212-352-9900/9906
212-365-9977/9979
212-529-9900/9906
212-562-9977/9979
212-982-9977/9979
212-986-9977/9979

     The lower number is the tone side (singing switch).  The higher 
number is always silent.  The tone disappears on the lower number 
when somebody dials in the other side of the loop.  If you are one 
the higher number, you'll have to listen to the clicks to see if 
somebody dialed-in.  The NYC 982 and 986 loops are different from the 
others.  Usually when you park on a loop, you will hear whoever cal
led in on the other half.  When they're done, the next caller, if 
any, will be queued in, one after another.  On the NYX 982 and 986, 
you sometimes can't get any more callers in after the first.  Fur
thermore, if you park one of these loops and there is nobody on the 
other end for more than four minutes, you may be automatically dis
connected.  These loops are good for back-up purposes when all other 
loops are busy.

99XX SCANNING:
     Most every exchange in Bell system has a wide variety of test 
numbers and other goodies, such as loops.  These goodies are usually 
found between 9900 and 9999 in your local exchange.  If you have the 
time and initiative, scan your exchange and you may become lucky.
     Here are my findings in the 914-268:

9901 - VERIFICATION (RECORDING OF A/C
       AND EXCHANGE)
9936 - VOICE # TO THE TELCO CO
9937 - VOICE # TO THE TELCO CO
9941 - CARRIER
9960 - OSC. TONE (TONE SIDE LOOP)
9963 - TONE (STOPS:  MUTED)
9966 - CARRIER
9968 - TONE THAT DISAPPEARS--RESPONDS
       TO CERTAIN TOUCH-TONE KEYS

     It will be easier for you to scan your exchange if you make up a 
chart like the one one the following page.  You should make your 
boxes big enough so that you can use a kind of shorthand to record 
your results in them.  For example:
B - Busy, try again later        R - Rings, try again later
O - intercept operator, "What # are you calling?"
R1- Recording 1, make a note of what recordings you get.
I - Ignore ] at a higher number, ignore it
T - Tone ] at a lower number...Loop!.

     There will be others and you should use other characters that 
you can understand.  Now, back to loops.  As you may have noticed, I 
found a muted loop and a tone side.  914-268 failed to come up with 
the silent side of a loop.  Therefore, there is no loop in that ex
change.  Then I scanned another exchange in my primary calling area 
(914-634) and I found a loop!

    (914) 634-9923/9924

     So, if at first you don't succeed, move onto another exchange.  
If you use the box chart method I outlined above, you will see a T 
and an I next to each other form a loop.  Some exchanges are special.  
For example, 914-623 is a testing bureau.  In this exchange, not only 
did I find a loop, but I also found several interesting tones, 
noises, and other testing functions.  Also, the more important the 
exchange is, the more you will find.  For example, in 914-623, I 
found well over 10 voice numbers.
     Also, loops are usually found in the 99XX series, foe example:

    (713) 324-1799/1499  is a loop.

     Also, 800 loops would be a definite plus, but they are not 
necessarily found in the 9900 through 9999.  I would check in the 
1XXX series first.
     Finally, remember that it is only a local call to find out what 
you CO has in store for you.  If you find anything interesting, be 
sure to drop me a line.

                ANI - AUTOMATIC NUMBER IDENTIFICATION

     ANI is a number that you call up that will tell you what number 
you are calling from.  This has a few uses.  First, were somewhere 
and the fone didn't have the number printed on it?  Or perhaps you 
were fooling around in some cans (those large boxes in fone poles 
that contain terminals for lineman use) and you want to know what the 
line number is.
     The ANI number varies from area to area.  Here are some I have 
seen:
  AREA CODE      ANI
    914          990
    212          958
    516          958

     To find others to add to this meager collection, check for three 
digit numbers, usually in the 9XX series, excluding 911.  In some 
areas, you will need to use 1-9XX-1111.  ANI may also be 99XX.

RINGBACK:
     Ringback, as its name implies, calls back the number you are at 
when you dial the ringback number.  You will need to do your own 
research to find the ringback number in your area.  It is usually 
three digits long, and you should: dial the 3 digit code, hang up and 
quickly pick up the receiver again, hang up again, and it should 
ring.
