This Enhanced Feature Pack upgrade enables Virtual Private Networking (VPN) and Voice Quality (VQM) monitoring in the NetVanta 4305. With this upgrade, the NetVanta 4305 supports up to 1,000 simultaneous IPSec VPN tunnels and encryption algorithms like DES, 3DES, and AES. By supporting IPSec, the NetVanta 4305 is fully compatible with other IPSec VPN-equipped NetVanta products. In addition, with the added VQM capabilities, the NetVanta 4305 also captures MOS, jitter, delay, and packet loss statistics necessary to troubleshoot VoIP calls. This powerful, yet graphically intuitive, diagnostic tool allows for quick isolation of network issues to ensure superior call quality.
