The P-662H-D series is compatible with high-speed ADSL, ADSL2 and ADSL2+ interfaces over existing copper lines. With speeds of up to 12Mbps (ADSL2) or 24Mbps (ADSL2+), the P-662H-D series offers higher data transfer rates and better bandwidth than traditional ADSL gateways. It also supports RE ADSL (Reach Extended ADSL) for higher speed and longer distance.
The ICSA-compliant ZyNOS operating system ensures state-of-art firewall performance and robust security on the P-662H-D Series. Based on stateful packet inspection, DoS (Denial of Service) and DDoS features, it provides the first line of defense against hackers, network intruders, and other malicious threats. Furthermore, its VPN feature supports data encryption over the Internet to ensure secure data transmission between two sites, and replaces expensive leased lines, allowing global interconnectivity with minimal expense.
The P-662H-D Series features a fail-over and fall back WAN backup solution for complete reliability. When the DSL connection fails, traffic is forwarded to either a backup ISDN or analog modem to maintain data transfer. When the DSL connection is re-established, traffic is fully restored. The P-662H-D Series also performs backup functions by redirecting traffic to a specific gateway to ensure availability of the Internet. The WAN backup solution saves device maintenance cost and reduces loss from daily operation.
