Overview

NB-301A (G.shdsl bis LAN Extender) from Netsys provides a broadband transmission speed up to 5.7Mbps through

G.shdsl bis connection over single pair copper line for point-to-point LAN connectivity between two sites. With its rate

adaptive features, NB-301A provides longer reach on transmission distance. Users may also select a fixed data rate for the

copper line ranging from 144kbps to 5,696kbps.

A pair of NB-301A offers a cost effective solution for bandwidth-hungry applications such as video-conferencing and

distant learning over twisted pair telephone line. NB-301A is indeed an ideal symmetrical broadband solution for

LAN-to-LAN connectivity, Internet access, VOIP application and etc.

Step 2. Connect Ethernet to RJ-45 Port with CAT 5 LAN cable

Step 3. Connect the power adapter to the NB-301A 12VDC outlet

Step 4. Turn on the power. Set one NB-301A as STU-C from Console port, and the other NB-301A as STU-R

Step 5. Set the desired Data Rate for G.SHDSL connection from Console port. Note that both NB-301A must set the same

data rate settings.

Step 6. Both units of NB-301A will automatically connect with each other.

Turn on the power and NB-301A will then execute self-test routines. There will be 2 or more handshaking cycles when adaptive

rate is selected. The system will automatically adapt to maximum rate according to the line distances. The maximum rate is

5696 kbps for 1-pair G.SHDSL line.
