Lamp Test
The Lamp Test is a test of the status indicators (LEDs) and liquid crystal display (LCD) on the DSU's control panel (both models). Any indicator that does not flash is not functional.
Note that if all LEDs are functioning, all the indicators on the Model 3550 DCP are flashing steadily. In a COMSPHERE 3000 Series Carrier, the indicators on the SDCP remain ON. The LCD on the DCP or SDCP alternately flashes solid blocks, moving from position to position on the display until the test is aborted.
Pressing any key except the 
key will stop the LCD portion of the Lamp Test and return you to the DSU Test menu so you can abort the test. Once aborted, the LCD and LEDs stop flashing.
Configuration Branch
The Configuration (Confg) branch allows you to configure or customize the DSU and its equipment (DBM or TDM/Flex) to fit your site's requirements, to enter and change telephone numbers (if a DBM is installed), and to specify the mode for viewing or editing configuration options.
The 3550 Series DSUs have two special features that simplify configuration of your DSU: Menu mode and the preset
It is recommended that you set the Menu mode before you select an application configuration, or access option sets.
Selecting Menu Mode
By selecting Menu from the Configuration Options (Opts) branch, you can
•View and configure options in each option set, or

This feature saves time and simplifies customization of your DSU's configuration. Appendix B, Configuration Worksheets, summarizes the unit's configuration options for each Menu mode selection.
