Logging in via Access Security Gateway 
(session establishment)
Use the following procedure to log in to the system via the ASG interface:
NOTE:
The numbers shown as challenges and responses in the procedures below 
are for example purposes only. They will not be the numbers you actually 
use or see on your ASG Key.
1. Connect to the system administration/maintenance port.
The system responds with the login prompt.
2. At the prompt, type your valid login ID and press 
Return.
The system verifies the login ID and transmits the challenge in the form of a 
7-digit number (for example, 
5551234).
3. Turn on your ASG key, press the button labeled 
Red to enter authentication 
mode, type your PIN, and press 
Enter.
The ASG key responds with a challenge prompt.
4. On the ASG key, at the challenge prompt, type the 7-digit challenge 
number you see on your PC (leave out the “-”, for example, 
5552739) and 
press 
Enter.
The ASG key generates a response number (for example, 
999-6713).
5. On the PC, at the 
Response prompt, type the response number generated 
by the ASG key (leave out the “-”, for example, 9996713) and press 
Return.
The system verifies the response. If correct, DEFINITY logs you on. If the 
response is incorrect, return to Step 1. 
NOTE:
Three login/challenge/response attempts are permitted. If the user is not 
authenticated after the third response, the user sees the message
INVALID LOGIN
 and the session will be terminated. If this happens, see 
the appropriate maintenance book for your system.
