The Myth of the 2600Hz Detector
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Just about everyone I talk to
these days about ESS seems to be
scared witless about the 2600Hz
detector. I don't know who thought
this one up, but it simply does not
exist. So many of you people whine
about this so-called phreak catching
device for no reason. Someone with
AT&T said they had it to catch phrea-
kers. This was just to scare the
Blue-Boxers enough to make them quit
boxing free calls.
I'm not saying ESS is without its
hang-ups, either. One thing that ESS
can detect readily is the kick-back
that the trunk circuitry sends back
to the ESS machine when your little
2600Hz tone resets the toll trunk.
After an ESS detects a kick-back it
turns an M-F detector on and recordes
any M-F tones X-mitted.
---------------------------------------
DEFEATING THE KICK-BACK DETECTOR
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
As mentioned in my previous
note, kick-back detection can be a
serious nuisance to anyone interested
in gaining control of a trunk line.
The easiest way to by-pass this
detection circuitry is not really by-passing
it at all, it is just letting the
kick-back get detected on some other line.
This other line is your local
MCI, SPRINT, or other long distance
carrier (except AT&T). The only
catch is that the service you use
must not disconnect the line when
you hit the 2600Hz tone.
This is how you do it: Call
up your local extender, put in the
code, and dial a number in the 601
area code and the 644 exchange.
Lots of other exchanges work across
the country, I'm sure, but this is
the only one that I have found so
far. Anyway, when it starts ringing,
simply hit 2600Hz and you'll hear the
kick-back, (ka-chirp, or whatever).
Then you are ready to dial whoever
you want (conferences, inward, route
and rate, overseas, etc.) from the
trunk line in operator tones!
Since blowing 2600Hz doesn't make you
you a phreaker until the toll equip-
ment resets the line, kickback
detection is the method AT&T chooses
(for now).
This information comes as a
result of my experiments & experience
and has been verified by local AT&T
employees I have as acquaintances.
They could only say that this is
true for my area, but were pretty
sure that the same idea is imple-
mented across the country.
=======================================
Now that you know how to access a trunk
line or as operators say a loop, I will
tell you the many things you can do
with it.
Here is a list of AT&T services acces-
sible to you by using a Blue Box.
A/C+101 Toll Switching
A/C+121 Inward operator
A/C+131 Information
A/C+141 Route & Rate op.
A/C+11501 Mobile operator
A/C+11521 Mobile operator
Starting Conferances:
---------------------
This is one the most useful attributes
of blue boxing. Now the confs. are up
24 hours/day and 7 days/week and the
billing lines are being billed.
Since I beleive the above is true
(about the billing lines being billed)
I would recommend that you never let
your # show up on the conf. if you
started it, put it on a loop and then
call the loop. ENOUGH BULLSHIT!!!!!
To start the conf. dial one of these
three numbers in M-F while you are on
the trunk.
213+080+XXXX
XXXX=1050,3050
special XXXX=1000,1100,1200,1500,2200,
2500.
These #s are in L.A. and are the
most watched, I do not advise using
this NPA.
312+001+1050 or 3050
914+042+1050 or 1100,1200 ect..
