The modem is locally operated by using the front panel keypad (Figure 4-1). The keypad
consists of six keys. Each key provides one or more logical functions:

] and [

] These keys are used primarily to change configuration data (numbers), but are
also used at times to move from one section to another.
The modem responds by beeping whenever a key is pressed:
•
A single beep indicates a valid entry and the appropriate action was taken.
•
A double beep indicates an invalid entry or a parameter is not available.
The modem front panel control uses a tree-structured menu system (Figures 4-2 through
4-16) to access and execute all functions. The base level of this structure is the sign-on
message that is displayed on the front panel when the modem power is turned on:
•
Line 1 of the sign-on message is the modem model number (SDM-9000).
•
Line 2 is the version number of the firmware implemented in the modem.
The main level of the menu system is Function Select. This may be accessed from the
base level by pressing any of the arrow keys. From the Function Select menu, the user
may select any one of five functional categories:
Note: The user should proceed to the Utility menu and establish the identity of the
modem before proceeding with the Configuration menu.
