For your safety, be sure to read and follow all warning notices and instructions before device use.
DO NOT open the device or unit. Opening or removing covers can expose you to dangerous high voltage points or other
risks. ONLY qualified service personnel can service the device. Please contact your vendor for further information.
Use ONLY the dedicated power supply for your device. Connect the power cord or power adaptor to the right supply voltage
(110V AC in North America or 230V AC in Europe).
DO NOT use the device if the power supply is damaged as it might cause electrocution. If the power supply is damaged,
remove it from the power outlet. DO NOT attempt to repair the power supply. Contact your local vendor to order a new power
supply.
Place connecting cables carefully so that no one will step on them or stumble over them. DO NOT allow anything to rest on
the power cord and do NOT locate the product where anyone can work on the power cord.

Description
1.1 Product Description
The NT205B, a SHDSL (Single-pair High-bit-rate Digital Subscriber Line) LAN Extender, provides a broadband transmission with
bandwidth up to 5.696Mbps over a single pair of copper wires for LAN connection between two local area networks. NT205B
provides a console port for users to configure the settings and to monitor the DSL connection status.
NT205B conforms to ITU-T G.991.2, the GSHDSL requirements. Each NT205B can be configured as either STU-C for the central
side or STU-R for the remote side. A pair of NT205B offers a cost effective symmetrical broadband solution for bandwidth-hungry
applications such as LAN-to-LAN connection, Internet, etc.
Features:
ITU G.991.2 Annex A, Annex B and Annex F
Symmetrical downstream and upstream data rates from 192Kbps to 5.696Mbps
Auto-Negotiation for 10/100 BaseT
Auto-MDIX for Auto Ethernet Tx/Rx Swap
