Security
Certain features of the system can be protected by passwords to prevent
unauthorized users from abusing the system. You should assign passwords
wherever you can and limit knowledge of such passwords to three or fewer
people.
Nondisplaying authorization codes and telephone numbers provide another
layer of security. For more information, see Appendix A, "Customer Support
Information."
Throughout this document, toll fraud security hazards are indicated by an
exclamation point inside a triangle and the words Security Alert.

Security Alert:
Security Alert indicates the presence of toll fraud security hazard. Toll
fraud is the unauthorized use of your telecommunications system by an
unauthorized party (e.g., persons other than your company's employees,
agents, subcontractors, or persons working on your company's behalf).
Be sure to read "Your Responsibility for Your System's Security" on the
inside front cover of this book and "Security of Your System: Preventing
