Your Responsibility for Your System’s Security
Toll fraud is the unauthorized use of your telecommunications system by an unauthorized party, for example,
persons other than your company’s employees, agents, subcontractors, or persons working on your company’s behalf.
Note that there may be a risk of toll fraud associated with your telecommunications system, and if toll fraud occurs, it
can result in substantial additional charges for your telecommunications services.
You and your system manager are responsible for the security of your system, such as programming and
configuring your equipment to prevent unauthorized use. The system manager is also responsible for reading all
installation, instruction, and system administration documents provided with this product in order to fully understand the
features that can introduce risk of toll fraud and the steps that can be taken to reduce that risk. Lucent
Technologies does not warrant that this product is immune from or will prevent unauthorized use of common-carrier
telecommunication services or facilities accessed through or connected to it. Lucent Technologies will not be
responsible for any charges that result from such unauthorized use. For important information regarding your
system and toll fraud, see Appendix A, “Customer Support Information.”

frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference, in which case the user will be required to correct the interference at his own expense. For further FCC
information, see Appendix A, “Customer Support Information.”
