Through Subscriber Management, the Cuda 12000 provides added security
for your cable network against:

■Unwanted traffic from entering the cable network
To achieve added security, the Cuda 12000 provides protocol filtering to and
from the cable modem, and limits the number of IP addresses available to
Customer Premise Equipment (CPE) devices.
