SDSL NETWORK EXTENDER 2000
NOTE
While both ends of the Ethernet connection must have the
same duplex mode configuration, partner Provider Units
and Subscriber Units don’t have to be configured the same.
Duplex mode does not apply to the SDSL connection.
In half-duplex mode, Switch #4 is down. Receive and
transmit functions are mutally exclusive; data transmission
occurs in only one direction at a time. Packet collisions are
not uncommon.
In full-duplex mode, Switch #4 is up. The Ethernet line can
receive and transmit simultaneously, preventing packet
collisions and increasing aggregate bandwidth from 10
Mbps to 20 Mbps.
3. Plug the output cord of the Provider Unit’s power
supply into the barrel jack on the Unit’s rear panel.
4. Plug the power supply’s input cord into a working
AC outlet. Make sure that the Power, Link, Tx,
and Rx LEDs light up.
