DMD20/DMD20 LBST Universal Satellite Modem
B.3.3 Running in Demonstration Mode
Because of the possible interruption in traffic when the demonstration mode expires, several
indicators are used to inform an operator that the modem is indeed, operating in demonstration
mode. The most obvious of these are the flashing LEDs.
When the modem is running in demonstration mode, the Mod and Demod Test LEDs will be
flashing. The flashing will occur even when the modem is placed in a test mode where the LED
would normally be lit continuously.
A second indication can be found on the Features Menu as follows:
1. From the modem's Main Menu, scroll right to the SYSTEM Menu.
2. Scroll down.
3. Scroll right to the HW/FW CONFIG Menu.
4. Scroll down.
5. Scroll right to the FEATURES Menu. The second line will display DEMO.
A third indication can be found in the upgrade list as follows:
1. From the FEATURES Menu.
2. Scroll down.
3. Scroll right to the UPGRADE LIST Menu.
4. Scroll down.
5. Scroll right through the available list of options.
The top line identifies the options and the second line identifies the options status.
DEMO MODE indicates that the option is has been temporarily activated and is now available for
evaluation as part of the modems feature set.
At the end of the demonstration period, the modem will revert back to its permanent configuration.
When it does, an interrupt in traffic will occur, regardless of whether or not a demo enabled
features was being run at the time. In addition, operator intervention may be required to restore
the data paths. In order to avoid this interruption in service, the user can cancel the
demonstration at any time by following the instructions outlined in the section on Canceling
Demonstration Mode.
