Enhancing system security
Toll fraud is the theft of long distance service and can come from both internal and 
external sources. When toll fraud occurs, your company is responsible for usage 
charges. In addition, unauthorized use may tie up your system, preventing your 
customers from reaching you and your employees from doing business.
Lucent Technologies designed the DEFINITY ECS to help you to limit toll fraud. 
However, there are steps that you, as the administrator, must also take to keep your 
system secure from unauthorized use.
