Ordering Information
NV-720D ADSL2+/VDSL2 Wi-Fi 11ac Modem Router





NV-720D is an ADSL/VDSL2 with 802.11b/g/n/ac Wi-Fi router modem. It is compliant with ITU-T G992.5 / G.993.2 standards and Auto-following CO side Band plan & Band profile. With built-in 802.11b/g/n/ac dual band wireless, it is able to deliver Wi-Fi speeds up to 867Mbps and is perfectly suitable for triple-play applications. NV-720D is designed to meet the ISPs requirements with future proof Vectoring and backward compatible with ADSL to cover end users in different loop range areas.

Vectoring Technology friendly Mode support

Vectoring is a transmission method that employs the coordination of line signals for reduction of crosstalk levels and improvement of performance. It is based on the concept of noise cancellation, much like noise-cancelling headphones. The ITU-T G.993.5 standard, "Self-FEXT cancellation (vectoring) for use with VDSL2 transceivers" (2010), also known as G.vector, describes vectoring for VDSL2. The scope of Recommendation ITU-T G.993.5 is specifically limited to the self-FEXT (far-end crosstalk) cancellation in the downstream and upstream directions. The far end crosstalk (FEXT) generated by a group of near-end transceivers and interfering with the far-end transceivers of that same group is cancelled. This cancellation takes place between VDSL2 transceivers, not necessarily of the same profile.

Easy Installation

The NV-720D is suitable for installing on any level surface (e.g. a table or shelf). NV-720D supports plug-and-play installation and is fully compatible with all kinds of network protocols. Furthermore, user can watch the status of each individual port via the LED indicators.

Enhanced Management

For efficient management, via Web interface, the NV-720D can be configured for enhancing managed functions such as QoS (Quality of Service)/DSCP, IEEE 802.1q Tag VLAN, SNMP v1/v2c, IGMP v3 and SSL/SSH security functions such as Packet filtering, DMZ, Mac Address based filtering, Parental Control, Application based filtering. NV-720D also support wireless security such as WEP, WPA, WPA2, TKIP, AES.
