Characteristics kỹ thuật
- Truyền data đối xưng speed high: GRT-504 used technology G.SHDSL.bis new most, for phép transmission data đối xứng ở speed 11.4Mbps on 4 sợ dây.
- Supports CO and CPE
- Firewall: Supports NAT and chưc năng firewall Advanced Stateful packet Inspection (SPI) firewall.
- QoS (Quality of Service): Supports ATM QoS and IP QoS. ATM QoS threeo gồm UBR (Unspecified bit rate), CBR (Constant bit rate), VBR-rt (Variable bit rate real-time) and VBR-nrt (Variable bit rate non-real-time).
- Supports VLAN: Supports IEEE 802.1Q Tagged and port-threesed VLAN.
- Chế độ hoạt động: Supports 2 chế độc connection router and bridge.
- Virtual Server:Allows users outside Internet truy cập ando server dựng bên in LAN network
- VPN Pass through Support:máy tính PCs with software VPN (Virtual Private Networking) used PPTP, L2TP, and IPSec has thể tạo connection VPN đi qua GRT-504.
- Supports DMZ Support:The GRT-504 has thể dịch địa chỉ IP network công cộng thành địa chỉ bên trọng LAN network tạo connection 2 chiều between máy chủ and ngừơi dùng bên outside Internet. Nó provides phương pháp brand quả to chạy the ứng dụng not chạy in mội trường NAT.
- Supports RIPv1/v2
- Supports Simple Network Management Protocol (SNMP):SNMPv1/v2
- Supports xác thực users PPPoA or PPPoE
