4.1.2 Front Panel Controls
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:
Key
Function
[ENTER]
[ENTER] is used to select a displayed function or to execute a modem
configuration change.
[CLEAR]
[CLEAR] is used to back out of a selection or to cancel a configuration change
which has not been executed using [ENTER]. Pressing [CLEAR] generally
returns the display to the previous selection.
[
←
] and [
→
]
These keys are used to move to the next selection or to move the cursor for
certain 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.

] to move from one selection to another. When the desired function is
displayed on line 2, select that level by pressing [ENTER]. After entering the appropriate
functional level, move to the desired function by pressing [

]. Refer to the
following section for information on individual functional categories and their functions.
