Advanced Security ADSL 2+ Gateway
Benefits
Higher-speed Internet Access
The P-661H 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-661H 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. With
excellent performance and upward compatibility, the P-661H Series is great
as the bridge between today's communications needs and tomorrow's
converged services.
Robust Firewall Security and IPSec VPN
The ICSA-certified ZyNOS operating system ensures state-of-art firewall
performance and robust security from the P-661H series. Based on Stateful
Packet Inspection, DoS (Denial of Service) and DDoS features, it provides the
first line defense against hackers, network intruders, and other harmful
threats. Furthermore, its VPN feature supports data encryption over the
Internet to ensure secure data transmission between two sites, and can be
used to replace a private leased line, allowing global interconnectivity with
minimal expense.
Media Bandwidth Management
The P-661H series enables network administrators to allocate network
resources and to guarantee Quality of Service (QoS). The MBM (Media
Bandwidth Management) function prioritizes media services, and increases
productivity and efficiency in daily operations by tailoring a system to
specific demands such as VoIP, video streaming, video-conferencing or MP3
applications.

Trend Micro Security Service (TMSS)
The embedded TMSS (Trend Micro Home Network Security Service) feature
not only helps to identify the vulnerabilities and security holes on PCs, but
also protects both the network and the PCs within from virus and hacker
attacks. TMSS includes redirected page setting, virus protection and
parental control that are easy to configure via the TMSS Dashboard.
