INTRODUCTION: ������������� Perhaps one of the greatest systems created by AT&T is the System 75. With access to one of these, a user will have virtually unlimited control of a companie's phone systems. These can be used to create PBX's, bridges, and loops. This is a step, by step guide to creating your own PBX. In order to make this easier to understnad, we have included a capture from an actual System 75 as we created a PBX on it. Without further delay, we will now procede. STEP 1. FINDING A SYSTEM 75: ���������������������������� System 75's are usually found in large companies, so you would be best off scanning downtown areas, but they have been found everywhere. After you have gotten a list of carriers, now you have to indentify a System 75. STEP 2. IDENTIFYING A SYSTEM 75: �������������������������������� First of all the first tell-tell sign of a System 75 is the 1200 baud connection. To connect with a System 75, you will want to set yourself for 1200 7-E-1. You will also want to use VT100 emulation. I will now include a capture from a System 75: ������������������������������������������������������������������������������� ATDT ******* CONNECT 1200 KEYBOARD LOCKED, WAIT FOR LOGIN (screen clears) Login: **** [Note: The account names and passwords have] Password: ****** [not been included for obvious reason.] INCORRECT LOGIN Login: ***** Password: ******* Terminal Type (513, 4410, 4425): [513] [Bell 513 emulation is basically] [VT100] ������������������������������������������������������������������������������� STEP 3. THE INITIAL SURVEY: ��������������������������� I suggest making two calls to the System, first to make a survey and capture all of the information in the system. Your first just trying to get information on all of the lines running into the system to find a suitable host for the PBX. In making it easier to understand, all of the things you need to type are in the { }. Once your in, you will see this screen: �������������������������������������������������������������������������������
