The TZ 170 SP, part of SonicWALL's TZ 170 Series, is a high-performance, multi-layer network security platform that provides businesses, telecommuters and small office networks with constant access to critical data. Should the primary broadband connection go down, the TZ 170 SP ensures continuous uptime for VPN connectivity by automatically failing over to either a second WAN connection or an integrated analog modem. Once the broadband connection has been re-established, the TZ 170 SP detects the restored connection and automatically fails back, ensuring the best possible connectivity.
