|
||
Well, here it is, the list from hell. Sure beats the old lists of 100
|
||
or so three letter acronyms. The whole reason for this list is so that
|
||
you can crack almost ANY bell document. This list came from a few
|
||
lists (one in Phrack a while back) and a few other Telephony lists
|
||
here and there. Though it must be noted (and i want to take credit for
|
||
it) that well over half of the acronyms and abbreviations were typed
|
||
in by me, inputed into my database (of course I am not about to give
|
||
out my database).
|
||
It is always a good idea to start a database, one will learn a lot
|
||
faster. It is doing things scientific like, and for someone as
|
||
compulsive as I, solving the puzzle of the telephone company was easy
|
||
as pie. I must say that all the hackers I have meet, and talked to are
|
||
all compulsive as hell <G>. I think it is just what it comes down to,
|
||
who is willing to learn. Any ways here is two fields in my database,
|
||
one small part, but worth it. Though i do not think it will be able
|
||
to help most of you out, just gets into too much, and understanding
|
||
which acronym goes where, and understanding what goes where is hard.
|
||
Well good luck!
|
||
|
||
Greets to Bell Northern Labs, never see too much from you press wise!
|
||
and to SRI, should have come to Cal. hah (Don knows what I am talking
|
||
about, his funding is short)
