Zyxel VMG3312-T20A, Wireless N VDSL2 4-port Gateway Combo WAN Gigabit Gateway

The Zyxel VMG3312-T20A is an advanced VDSL2 gateway that provides autosensing between VDSL2 and ADSL2+ for high-speed Internet access. In addition, with supports to G.vectoring, it increases speed and coverage to compete with other broadband technologies without infrastructural change.

The Zyxel VMG3312-T20A integrates an IEEE 802.11 b/g/n access point and a 10/100 Ethernet switch for Local Area Network (LAN) access. It can act as a concentrator or power hub to distribute contents between different devices connected inside the LAN wired and wirelessly. We’ve also enhanced the WiFi ability to ensure a quality user experience.

Additionally, it comes with the multiple-WAN function suitable for future FTTH deployments with optimized CAPEX.

Users could also leverage the USB interface on the Zyxel VMG3312-T20A for file sharing or pair with a 3G USB dongle for mobile connectivity.

VDSL2 G.vectoring for maximized service coverage

Combo WAN-in-a-box for optimized CAPEX in FTTH/VDSL2 deployments

2.4 GHz 11n (2x2) for superior performance and coverage

Advanced QoS to ensure quality of triple-play services

Remote provisioning and management through TR-069/TR-181 issue-2

ROM-D feature for easy distributor/operator customization

Easy upgrade to 3G USB support through configuration files

VDSL2 Vectoring for maximized service coverage
The Zyxel VMG3312-T20A Wireless N VDSL2 Combo WAN Gateway comes with USB supports to the Vectoring technology that eliminates crosstalk or interference among different VDSL lines. With the mechanism, Vectoring significantly increases bit rates to compete with cable/fiber technologies as well as to enlarge service coverage without changing the current infrastructure — a way to significantly save cost comparing to fiber-to-thehome (FTTH) deployments, and the CAPEX can be optimized by the improved data rates and coverage without upgrading equipment.
