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 com- pany’s employees, agents, subcontractors, or persons working on your company’s behalf. Note that there may be a risk of toll fraud associ- ated with your telecommunications system and, if toll fraud occurs, it can result in substantial additional charges for your telecommunica- tions services.

You and your system manager are responsible for the security of your system, such as programming and configuring your equipment to pre- vent unauthorized use. The system manager is also responsible for reading all installation, instruction, and system administration docu- ments provided with this product in order to fully understand the fea- tures 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 com- mon-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.
