Descriptions
The SHDSL (Single-Paired High Speed Digital Subscriber Loop) routers comply with G.991.2
standard with 10/100 Base-T auto-negotiation. It provides business-class, multi-range form
64Kbps to 2.304Mbps (for 2-wire mode) or 128kbps to 4.608Mbps (for 4-wire mode) payload rates
over exiting single-pair copper wire. The SHDSL routers are designed not only to optimize the
service bit rate from central office to customer premises also it integrates high-end
Bridging/Routing capabilities with advanced functions of Multi-DMZ, virtual server mapping and
VPN pass-through.
Because of rapid growth of network, virtual LAN has become one of the major new areas in
internetworking industry. The SHDSL routers support port-based and IEEE 802.1q VLAN over
ATM network.
The firewall routers provide not only advanced functions, Multi-DMZ, virtual server mapping and
VPN pass-through but advanced firewall, SPI, NAT, DoS protection serving as a powerful firewall
to protect from outside intruders of secure connection.
The 4-port routers support four ports 10Base-T /100Base-T auto-negotiation and auto-MDIX
switching ports to meet the enterprise need.
The SHDSL routers allow customers to leverage the latest in broadband technologies to meet their
growing data communication needs. Through the power of SHDSL products, you can access
superior manageability and reliability.
