G.SHDSL Ethernet Extender, 2-wire

Save in cabling costs! The Black Box 10BASE-T/100BASE-TX G.SHDSL Extender works as a symmetrical high data rate DSL (G.SHDSL) modem and enables you to use just two wires to extend Ethernet and Fast Ethernet communications at higher speeds in a point-to-point application.

Speeds Featuring symmetric, high-speed digital subscriber line technology, the G.991.2 standard device delivers rate-adaptive nx64 speeds as high as 15 Mbps.

Wiring The extender/NTU works in a pair communicating across dry, two-wire copper cable of any gauge from 19 AWG (0.9 mm) to 26 AWG (0.4 mm). You may even be able to use the telephone wiring already connecting offices or buildings in your application.

Settings Using the DIP switch on the extender or a Telnet connection, you can set its rate in 64-kbps increments to provide a precise amount of bandwidth to users and to get either greater speed or greater distance. The extender/NTU uses Trellis-Coded Pulse Amplitude Modulation (TCPAM) to enhance its performance and support distances twice as far as conventional TDM technologies.

Mirroring The G.SHDSL Two-Wire Extender also includes a probe to determine the optimum data rate supported by the link between local and remote units. In addition, an error monitor inspects the line for intervals that exceed its user-set error threshold and, if necessary, restarts the link automatically.

For easy troubleshooting, the extender features front-panel LEDs and other diagnostic tools for detecting errors on the two-wire connection.

Ethernet The 10BASE-T/100BASE-TX G.SHDSL Extender features (4) RJ-45 connectors, that autosense 10- or 100-Mbps network links, and autonegotiate for full- or half-duplex operation, and delivers bridged-Ethernet connections to distant users.
Web Management You can extend corporate LAN-to-WAN communications at higher speeds or at a longer distance.
