4-Port Ethernet Extender

Featuring symmetric, high-speed digital subscriber line technology, the G.991.2 standard device delivers rate-adaptive nx64 speeds as high as 15 Mbps. 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.Features:Provides data rates up to 15 Mbps over 2-wire, voice-grade wiringSelectable 64-kbps rates enable you to choose the bandwidth you needHas 4-Port integrated 10/100 Ethernet switchProbes voice-grade wiring to determine the optimum data rate supportedSupports G.994.2 handshaking, enabling it to adapt the rate automatically to the existing line conditionsSimple to set up and, once configured, operates transparentlyTransformer-coupled two-wire interface boasts 1500-VAC isolationWorks with other extender/NTUs to provide interface conversion along with network termination and extensionMax reach of 30 kftUsing the DIP switch on the extender/NTU 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. The G.SHDSL Two-Wire Extender/NTU 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/NTU features front-panel LEDs and other diagnostic tools for detecting errors on the two-wire connection.The 10BASE-T/100BASE-TX G.SHDSL Two-Wire Extender/NTU features (4) RJ-45 connectors, autosenses 10- or 100-Mbps network links, autonegotiates for full- or half-duplex operation, and delivers bridged-Ethernet connections to distant users. You can extend corporate LAN-to-WAN communications at higher speeds or at a longer distance.
