3Com NBX 100 Administrator's Manual page 303

the access digit for the Personal Operator is the digit you did not use for
the System Operator. (Access digits cannot be the same for both
operators.)
The two operators are functionally identical: either can be referenced as
the Personal Operator or the System Operator, depending on your site's
requirements. For example, you could designate the extension for the
System Operator as your Personal Operator.
What Can You Assign As An Operator?
