VDSL-class Bandwidth with
ADSL2+ Port Bonding
Benefits
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.

P-663H-51
ZyXEL P-663H-51 is an all-in-one ADSL2+ gateway for Home, SOHO and
SMB applications. Featuring two ADSL2+ WAN ports and four
10/100 Mbps Ethernet LAN ports, the P-663H-51 provides SPI (Stateful
Packet Inspection), anti-DOS (Denial of Service) and many Firewall
security features to protect against network intrusion and attacks.
In addition, advanced features such as IP multicasting, IGMP
proxy/snooping, fast leave and IP QoS fulfill the need of triple-play
services, while the G.bond-based port bonding feature groups the 2
ADSL2+ physical ports into a logical link. The link not only provides
VDSL-equivalent bandwidth with much longer loop length, its load-
balance feature between the two ports also makes the P-663H-51 the
best choice for business and high-end market applications.
