Bonded ADSL2+/VDSL2 + 4-Port WiFi

THE SR550n BONDED DSL/FTTH GATEWAY provides high performance and flexibility for broadband and IPTV subscribers, effectively bridging the gap between copper and fiber. Utilizing the latest Broadcom VDSL2 chipset, the SR550n bonds two VDSL2 lines (or two ADSL2+ lines), extending the rate/reach of high-bandwidth services and providing high-availability with automatic failover. Under the hood of the SR550n is also a high-power output 802.11n WiFi Access Point and 4-port Ethernet switch. The highly-integrated design consumes less power than previous generation VDSL2 gateways. The SR550n can also be used as a Gigabit Ethernet WAN gateway, via the onboard SmartPort™, and includes a carrier-grade router, firewall, and industry-leading TR-069 management.

The SR550n is designed with ease of deployment in mind. The Automatic Broadband Connection feature eliminates the need for an installation CD or manual configuration and, if you decide to deploy a remote management solution, the SR550n offers maximum interoperability with industry-leading TR-069 remote management systems.
