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. 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 mission- critical Internet applications with benefits of the integrated bandwidth.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. 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.
