VNTU 767 Series

VDSL2 Modem

VNTU series works as an Ethernet extender through VDSL2 lines, it provides rich Ethernet features for different applications, including firewall, IEEE 802.1Q, policy-based QoS functions such as traffic policy, traffic meter, and flexible scheduling. It also supports port-based and tag-based VLAN with up to 16 VLAN groups. VNTU series also provide high-speed dedicated symmetrical data transmission and utilizes DSL bandwidth.

  • VNTU 767 is a standalone model. For line card type compatible to iEAC-16, please refer to VNTU 766
