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 programming 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 unau-
thorized use. For important information regarding your system and toll fraud, see Appendix A, “Customer Support Information.”

Support Information.”
