•
•
•
•
Wire-speed performance for concurrent services at T1/E1 WAN rates
Enhanced investment protection through increased performance and modularity
Enhanced investment protection through increased modularity
Increased density through High-Speed WAN Interface Card Slots (two)
Support for over 90 existing and new modules
Support for majority of existing WICs, VWICs, and VICs (data mode only)
Two Integrated 10/100 Fast Ethernet ports
Security
o On-board encryption
o Support of up to 800 VPN tunnels with the AIM-EPII-PLUS Module
o Antivirus defense support through Network Admission Control (NAC)
o Intrusion Prevention as well as stateful Cisco IOS Firewall support and
many more essential security features
In ABC project an 1MBPS Lease line connected to one of the Serial port of this router
and the management port of External Tipping point connected with Fast Ethernet port.
