• Ethernet data interface and RS-232 / RS-485 asynchronous multiple port options
• Software selectable dual / single antenna port options (dual antenna port for external duplexers or
filters)
• Data encryption and authentication using 128,192 and 256 bit AES and CCM security standards
• Terminal server operation for transporting RS-232 / RS-485 traffic over IP or Ethernet and converting
IP packets to a local physical serial port

• QoS per port (Ethernet, serial, management)
• L2 / L3 / L4 filtering for security and avoiding narrow band radio network overload
• L3 Gateway Router mode with standard static IP route for simple routing network integration
• L3 Router mode with per Ethernet interface IP address and subnet
• L2 Bridge mode with VLAN aware for standard Industrial LAN integration
• Ethernet header and IP/TCP / UDP ROHC header compression to increase the narrow band radio
capacity
• Ethernet and serial payload compression to increase the narrow band radio capacity
• Pseudo peer to peer communication between remote radios through base-repeater or repeater
stations
• SuperVisor web management support for element and sub-network (base-repeater-remotes)
management
