Effective Access Level
The ATI effective access level is the more restrictive between the Port/Session
access level and the Access level associated with the Login ID. For example, if a
login ID is created with an Access Level 1 and the Terminal Port is set for a Port
Access Level of 2, the effective access level to the ATI is 2.
