PART I: Introduction

This is a file typed up for beginners on PBXing.
If you know anything about PBX's at all this file will do you no good at all. It is very basic. Hope this helps some of you beginners. Now, on with the Gfile.

PART II: What are PBX's?

PBX's are telephone systems set up by very large corporations to make long distance (LD) phone calls for free.

I have heard many definitions for PBX's:

Public Brand Xchanges
Personal Business Xchanges
and a few other

Actually it stands for Private Branch Xchange [Useful to know this when you are asked to define abbreviations on those info-forms.

PART III: How do PBX's Work?

You should be familiar with 1-800 dialups already [1-800-xxx-xxxx]. If not get a gfile called "Phreaking - For the Beginners." These 1-800 allow dialups form mainly anywhere in the United States. But, not in some Foreign countries. It depends on what WATS line Company you are using. WATS [Wide Area Telephone Service] Lines are offered by AT&T at a rate of around $2000 dollars a month, which allows and unlimited amount of phone calls to that companies 1-800 number. The PBX works almost the same as a MCI, SPRINT, and other LD services work. It uses an INWATS [Inward Wats] line t the employees [or phreakers in your case] phone charge. Next, you dial the PBX, the computer on the other end will pick up the phone automatically and send you a tone [Similar to a dial tone]. This is when you enter you code. Next, enter the long distance number you wish to call [known as the Target Number]. If the code you entered is a valid one, the computer will call the number automatically and connect you too the BBS you wish to call. If you have a friend that moved or just some one you want to chat with that lives out of your area code. You can also do this without the use of you computer, just do it manually on your receiver.

PART IV: PBX's of The Past

A few years ago, PBX's were constructed without codes All you would have to do was call up the PBX [1-800-xxx-xxxx] and enter the number you wished to call. But then, Companies soon found out that their phones were being used by other people than their employees. So, they decided to add a little code to keep these people [Phreakershose were the good 'ole days. But it hasn't stopped anybody yet. And they never will.

PART V: Dialing a PBX

To dial the PBX, get a blank screen on your Communication package and type:

ATDT1800xxxxxxx,,,,,CODE,,Target.

Each comma tells the computer to pause for two seconds. You will have to fool around with a few times to find out the pauses. Also, you will have to experiment a little to find the length of the code.
