Zyxel VMG3925-T10C - ADSL / ADSL2+ / VDSL (FTTC) / FTTP / G.FAST Compatible
(includes initial despatch and configuration)

The Zyxel VMG3925-B Series Dual-Band Wireless AC/N VDSL2 Combo WAN Gigabit Gateway provides high-speed VDSL Internet access to meet the worldwide market requirements for multi-play services. 


G.vector to optimize performance and CAPEX

The Zyxel VMG3925-B Series of Dual-Band Wireless AC/N VDSL2 Combo WAN Gigabit Gateway features Vectoring technology to eliminate cross-talk or interference among different VDSL lines. With the mechanism, Vectoring significantly increases the bit rates to compete with cable/fiber technology as well as to enlarge the service coverage without changing the current infrastructure – a way to save cost significantly comparing to Fiber-To-The-Home (FTTH) deployments. In the meantime, the CAPEX can also be optimized by the improved data rates and coverage without upgrading the existing equipment.

Combo WAN for simplified ISP logistics and optimized CAPEX

With the Zyxel VMG3925-B Series, there’s no need for service providers to invest on and replace CPEs at customer sites when customers migrate from ADSL2+ or VDSL2 to PON or 3G as all they need to do is to unplug the DSL line, and then plug an Ethernet cable to the Ethernet WAN port. The existing CPE VMG3925-B Series will be used to terminate the IP connections via the WAN interface. In most cases, users can still connect with the original CPE without replacing the unit due to the difference between physical interfaces.

802.11ac technology for extreme performance and coverage

The Zyxel VMG3925-B Series features 802.11ac technology to provide the ultimate solution for both speed and coverage. With 802.11ac wireless data rates of up to 1.3 Gbps*, the VMG3925-B Series provides stable, reliable wireless connections for high-speed data and multimedia usages. The 802.11ac technology empowered the device to eliminate dead zones and to extend coverage while retaining backward compatibility with any WiFi certified device.

Quality of Service (QoS) support

With the QoS features from Zyxel VMG3925-B Series, service providers can freely design their QoS policies and prioritize mission-critical services such as IPTV and VoIP based on their service plan offerings. This increases network efficiency and productivity that enable service providers to offer a real multi-play solution that meets the needs of residential users.

TR-069 remote management

The Zyxel VMG3925-B Series incorporates the TR-069 standard management specifications for service providers to manage and configure client devices remotely without any end-user intervention. This feature offers a true “plug-and-play” experience while reducing deployment complexity to help saving operating and maintenance costs for service providers.
