- Boxing in the late '80s:
-
- While most of us have reverred to hacking and L/D accounts, some of us
- refuse to give up the purest form of telecommunications experimentation.
- While almost every step has been taken to secure the lines from unauthorized
- trunk access and use, what remains true even now, is that the learned phreaker
- always stays a step or two ahead of whatever forces prevent the phreakers'
- manipulation of controlled network facilities. While most of the information
- contained here is common, some truly dedicated to the art of Blue-Boxing may
- be oblivious to some of these methods of boxing with Big Brother:
-
- 2600htz line detection units:
-
- The infamous 2600htz Tone detection/traps can detect a 2600 going
- through the system without proper network procedure. These traps are
- newer than the Bell equipment installed in some of the earlier switching
- systems, so they are more versatile. In order for a TDU to be activated,
- the trunking frequency must be fairly pure; It must differentiate between
- a possible human voice in that range, or an innocent instrumental source,
- so they are much more liberal than the older Bell equipment.. When a
- fairly equal ratio of pink/white noise combined with a 2600htz tone is
- applied to the line, bell equipment may respond to the signal, while TDU
- may not. This method is not failsafe.. It has about a 10-15% failure
- rate (if not more) but is better than nothing.
-
- Network Toll-trunk test lines (trunk lines:)
-
- The phone system, in many cases, will have numbers for testing purposes
- which drop the line at the CO into a trunk. Many numbers like these exist
- in newer ESS installations, or many Xbar/Cbar systems. These numbers seem
- to be predominant in the 99XX range. This method is probably the safest,
-
- Screening-code initialization faults:
-
- Some phone systems have absent screening codes. For instance, if one
- were to dial 800/141-1212 they would reach an inward. This is HIGHLY
- unlikely, for DMS-100 / SR-100 systems (and probably most all others,)
- have the screening code set as a default in the software. Just check
- it out, or if you know any Telco employees, it may be possible to coax
- them into disabling "Subscriber-to-station screening." I know I did.
-
- Another way is to call your local intercept operator, and ask her to
- dial 800/141-1212, as intercepts are generally stupid, knowing only how
- to dial.
-
- Well, armed with this information, one may continue to explore the network with
- minimized paranoia. Enjoy, and look out for updates...
