P-663H-51 گیت وی 4 پورت +ADSL2

 توضیحات : 

Higher-speed Broadband Access

The P-663H-51 has two ADSL2/2+ WAN ports. With the ATM-based multi-paired bonding feature, the two ports can be grouped into a logical link boasting the bandwidth twice as fast as a single ADSL2/2+ port, and the bit rates of each individual port can be freely and independently changed by their respective PHY layer. If one of the member ports fails, the conveyed traffic will be moved to the other port. When the failed port recovers, it will seamlessly return to the logical link and share the transmission/reception of the upper-layer traffic.
 

Robust, State-of-the-Art IP Security

The P-663H-51 supports state-of-the-art Firewall features, Stateful Packet Inspection, anti-DoS (Denial of Service) and IP/MAC address spoofing protection for basic defense against hackers, network intruders and other hazardous threats.
 

Sophisticated QoS for Triple-Play Services

The P-663H-51 comes with complete ATM and Ethernet QoS mechanisms, as well as various IP QoS features (Packet classification/Rate Limitation/Queue Scheduling). The seamless QoS-mapping not only allows consistent and appropriate traffic treatment of packets, but also enables fulfillment of triple-play services. The IGMP proxy/snooping and fast leave (v1, v2) features also supports the IP multicasting service easily.
