5221G G.SHDSL 4-wire Firewall Router

The Proscend 5221, SHDSL (Single-Paired High Speed Digital Subscriber Loop) 4-wire routers with VLAN and firewall, comply with ITU-T G.991.2 standard optimized for small to medium size business environment. The SHDSL interface provides business-class, multi-range form 64kbps to 4.608Mbps symmetric payload rates over exiting copper wires.

With always on connection that DSL provides, the SHDSL routers provide advanced firewall, Stateful Packet Inspection (SPI) and DoS protection, serving as a powerful firewall to protect from outside intruders of secure connection. Proscend 5221 also support IP precedence with which network packet transverse IP precedence devices priority and the priority traffic is always serviced before traditional traffic.

Proscend 5221 are integrated 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 VLAN and IEEE 802.1q VLAN over ATM network.

The LAN interface of SHDSL 4-wire routers support 10/100 Base-T auto-sensing, auto-negotiation and auto-MDIX switching ports to meet the enterprise need. internetworking industry. The SHDSL 4-wire routers support port-based and IEEE 802.1q VLAN over ATM network.

Proscend 5221 support four ports 10Base-T /100Base-T auto-negotiation and auto-MDIX switching ports to meet the enterprise need.

The Proscend SHDSL routers allow customers to leverage the latest in broadband technologies to meet their growing data communication needs. Through the power of Proscend SHDSL products, you can access superior manageability and reliability.
