SHDTU03bF-ET10RS/A 2/4-Wire G.SHDSL.bis ATM/EFM Ethernet Bridge/Router

G.SHDSL.bis ATM/EFM TR069 Bridge/Router

The SHDTU03bF-ET10RS/A is a G.SHDSL bis Bridge/Router in 2-wire or 4-wire which complies with G.991.2 (2004) standards and has an optional built-in four port 10Base-T /100Base-TX auto-negotiation and auto-MDIX switch. The SHDTU03b family provides business-class, multi-range 192Kbps to 5.7Mbps (2-wire) or 384Kbps to 11.4Mbps (4-wire) payload rates over existing single or two pair copper wire. SHDTU03b-ET10R is designed not only to optimize the service bit rate from central office to customer premises but also integrates high-end Bridging/Routing capabilities with advanced functions such as Multi-DMZ, virtual server mapping and VPN pass-through. The G.SHDSL.bis router allows customers to leverage the latest in broadband technologies to meet their growing data communication needs. In bridge mode, the four switching ports may be configured for IEEE802.1Q VLAN or port based VLAN applications. The modem can be configured in either central or client mode providing a point-to-point solution.
