Product Overview

Main Features
  • E1/T1 G.SHDSL Two-Wire Extender/NTUs
Save in cabling costs! BLACK BOX® G.SHDSL Two-Wire Extender/NTUs enable you to use just two wires to extend communications at higher speeds in a point-to-point application.

Featuring symmetric high-speed digital subscriber line technology, these G.991.2 standard devices deliver rate-adaptive nx64 speeds as high as 4.6Mbps for extending Ethernet/Fast Ethernet, E1/T1, X.21, or V.35 networks.

The extender/NTUs work in pairs 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 extender/NTUs' DIP switches or an RS-232 console connection, you can set their rate in 64kbps increments to provide a precise amount of bandwidth to users and to get either greater speed or greater distance. The extender/NTUs use Trellis Coded Pulse Amplitude Modulation (TCPAM) to enhance their 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 192kbps speeds.

The G.SHDSL Two-Wire Extender/NTUs also include 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/NTUs feature front-panel LEDs and other diagnostic tools for detecting errors on the two-wire connection. The E1/T1, X.21, and V.35 extender/NTU models also feature a PRBS pattern generator and detector, and support basic error rate (BER) testing.

For G.703/G.704 connections, order the E1/T1 G.SHDSL Two-Wire Extender/NTU (ME231A). It features two BNC connectors and an RJ-48C jack, so it suits both unbalanced E1/T1 connections. Use this extender/NTU to connect to either a 75-ohm dual coax E1 or T1 network, or to link it to either a 120-ohm E1 or 100-ohm T1 twisted-pair network interface. It supports local and remote loopbacks.
