ZYXEL SBG3500 VDSL2/ADSL2+/4GE/WLAN/VPN

Flexible WAN Connectivity with High Availability for Small Offices
Networking services are now becoming more imperative for small businesses to take advantage of easy communication and effective services. The ZyXEL SBG3500-N Series Wireless N Fiber WAN Small Business Gateway is the “multi-WAN gateway” that provides high-speed Internet access for business users. Featuring not only VDSL2/ADSL2+ functionality but also one GbE WAN with Small Form Pluggable (SFP) interface, this device offers flexible multiple-WAN connectivity to adopt various Internet interfaces. It also enhances network performance for small businesses to pursue the ultimate success.

Multi-WAN connectivity with load balancing and failover
The ZyXEL SBG3500-N Series provides multiple WAN interfaces, including DSL and Gigabit Ethernet, for load balancing and WAN backup. Service providers can flexibly offer WAN services of the highest availability in one single box for small business owners to enjoy non-stop services. Powered by the load balancing and fail-over mechanisms among multiple WANs, it maximizes WAN stability for missioncritical Internet applications with benefits of the integrated bandwidth.

Increased bandwidth and flexible range
The advanced VDSL2/ADSL2+ bonding and dual-personality Ethernet WAN functionalities enable service providers to increase bandwidth and extend coverage. With the available copper lines, service providers can take advantage of VDSL2/ADSL2+ bonding to not only provide higher speeds for the existing subscribers, but also improve the user experience for those who are far away from the cabinet with stable, sufficient bandwidth regardless of the distance. Besides, if fiber lines are preferred, the ZyXEL SBG3500-N Series can use the Small Form Pluggable (SFP) interface to connect Fiber Ethernet for distances much longer than Gigabit networks, or simply connect to other Ethernet WAN devices without additional cost laying new fiber.

Robust security design
Based on Access Control List (ACL) rules, Stateful Packet Inspection (SPI), Denial of Service (DoS) and Distributed Denial of Service (DDoS) measures, the ZyXEL SBG3500-N Series provides the first-line defense against hackers, network intruders and other harmful threats. The configurable Demilitarized Zone (DMZ) is another benefit that provides more flexible accessibility while preventing external attacks toward the confidential resources and databases.

Superior wireless performance and high expandability
With built-in 802.11n technology, the ZyXEL SBG3500-N Series is the ultimate solution for exceptional security, speed and coverage. Featuring multiple SSIDs that allow companies to protect sensitive data by separating public Internet access from the company’s private LAN for staff and guests. These features not only provide high quality Wi-Fi access, but also make it easy for companies to share wireless connectivity without compromising security.

Moreover, the ZyXEL SBG3500-N Series has been designed to simplify the deployment and management when small businesses plan to build or expand the Wi-Fi network. SBG3500-N is with integrated WLAN controller functions capable of managing up to 10 Wi-Fi APs; this gives small businesses a quick, flexible approach to meet the growing Wi-Fi demand.

Safe, reliable Virtual Private Network (VPN) connections
The ZyXEL SBG3500-N Series allows small businesses to establish stable VPN connections with partners and branch offices; road warriors and telecommuters can use IPsec as well as L2TP or PPTP VPN to safely access corporate networks without maintaining VPN software on their PCs. Designed with VPN HA features to ensure that the VPN connectivity is always on for the business needs.

Inclusive network management
The ZyXEL SBG3500-N Series offers two-level login privilege mechanism to differentiate user segments; and the Internet service providers can also define the policies for the limited accounts to easily manage them with the integrated profile database. It also provides TR-069 and simple network management protocols for service providers to conduct remote device management tasks.
