web site by clicking on the blue URL in the Update Firmware window.
Update Firmware Window
The Update Firmware window lists the version of the firmware the Router is
currently using. If you would like to update, follow the instructions given on the
D-Link web site firmware update page to download the new firmware. You can
then use the DSL-504 Firmware Upgrade Utility included with the Router to
transfer the new firmware to the Router. For instructions on using the Upgrade
Utility software please read Appendix C.
The Installation CD-ROM included with the Router contains an installation file
for the DSL-504 Firmware Upgrade Utility. You should install this on the
computer you will use to make the occasional upgrades. Click on the setup.exe
file and the utility will be automatically installed.

OAM Loopback Test

OAM (Operation, Administration and Maintenance) loopback tests are used to
verify connectivity and path integrity along a specified ATM circuit. In the test,
an OAM cell is sent to an endpoint or to the end of the first segment of the ATM
path. If the path is available and the connections are functioning, an OAM cell
will be returned along the same ATM path and be detected by the Router. This is
very similar to a Ping test. The test can help to determine whether or not
connectivity problems originate from outside the LAN. Accessing the OAM
Loopback Test menu can perform an OAM loopback test. Click on the OAM
Loopback Test menu button to view this menu.
