Black Box G.SHDSL Two-Wire Extender/NTU Product Details
Featuring symmetric high-speed digital subscriber line technology, the G.991.2 standard device delivers rate-adaptive nx64 speeds as high as 4.6 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.
Using 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 - up to 9.9 miles (16 km) when using 19 AWG wiring and operating at 192-kbps speeds.
The X.21 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 X.21 extender/NTU also features a PRBS pattern generator and detector, and supports basic error rate (BER) testing.
Use the X.21 G.SHDSL two-wire extender/NTU to connect to an X.21 network. The extender/NTU has a DB15 connector that can be used for links to routers and other data terminal equipment (DTE) or to multiplexors or similar data circuit terminating equipment (DCE). The X.21 extender/NTU supports local and remote loopbacks.
