The Adtran NetVanta 1335 is a 1U rack-mountable multiservice access router and Layer 3 switch engineered for small to medium-sized businesses. It consolidates IP routing, Layer 3 switching, firewalling, VPN termination, and DSU/CSU functionality into a single platform, eliminating the need for separate appliances. The unit delivers 8.8 Gbps switching capacity with non-blocking architecture and 45,000 PPS routing throughput across a 24-port managed Fast Ethernet switch with two combo Gigabit uplink ports.
