Connecting the DS3 Line
Plug the DS3 Tx and Rx cables into the corresponding DS3 connection BNC ports on
the back of the DNE4500. Verify the connection: the DS3 Lnk LED will pulse once per
second to indicate that the DS3 connection is established and operational.
A DS3 network extender subscriber unit (DNE4500-S) must be connected via DS3 line
to a DS3 network extender provider unit (DNE4500-P or DNE4500-P-6-AC/DC). A
subscriber-to-subscriber or provider-to-provider connection will not function.
Connecting the Ethernet Line
The Ethernet port is 10/100 auto-negotiating. Set your PC, hub, or switch to
auto-negotiate (if applicable) before making the Ethernet connection. Plug the Ethernet
cable into the Fast Ethernet RJ45 port on the back of the DNE4500. Verify the
connection: solid illumination of the Fast Ethernet Lnk LED indicates an Ethernet
connection has been established. If the Fast Ethernet Lnk LED is illuminated but not the
Fast Ethernet 100 LED then a 10 Mbps connection has been established. If the Fast
Ethernet 100 LED is also illuminated, then a 100 Mbps connection has been
established.
For most applications, the DNE4500 connects to a PC using a straight-through Ethernet
cable and to a hub or a switch using a crossover Ethernet cable. For any other
connection combinations you must verify the pinout of the Ethernet device to which you
are connecting the DNE4500 in order to determine which type of cable is required.
