MN/U-SDM309B Rev. #
Test Mode (Yellow LED)
Flashes when the modem is in a test configuration.
3.1.3 Front Panel Controls
The Modem is locally operated by using the front panel key-pad (Figure 3-1). The key-
pad consists of six keys: Enter, Clear, Right Arrow, Left Arrow, Up Arrow, and Down
Arrow. Each key has it’s own logical function or functions:
Enter Key
The “Enter” key is used to select a displayed function or to
execute a change to the Modem’s configuration.
Clear Key
The “Clear” key is used to back out of a selection or to cancel
a configuration change which has not been executed using
the “Enter” key. Pressing the “Clear” key generally returns the
display to the previous selection.
Left & Right Arrow Keys
These keys are used to move to the next selection or to move
the cursor for certain functions.
Up & Down Arrow Keys
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 that
the key pressed was a valid entry and the appropriate action was taken. However, a
double beep when a key is pressed indicates that the key pressed was an invalid entry.
The Modem front panel control uses a tree structured menu system (Figures 3-2 to 3-7)
to access and execute all functions. The base level of this structure is the sign-on
message which is displayed at the front panel upon modem power up. Line one of the
sign-on message is the modem model number (SDM309) and line two is the version
number of the firmware implemented in your modem. The main level of the menu system
is the ‘sELECT” menu which may be accessed from the base level by pressing any of the
arrow keys. From the ‘sELECT” menu you may select any one of five functional
categories: configuration functions, monitor functions, fault functions, stored fault
functions or utility functions. Use the right and left arrow keys to move from one
selection to another, when the desired function is displayed on line two you can enter
that level by pressing the “Enter” key. Once you have entered the functional level of your
choice, move to the desired function by using the right and left arrow keys. Refer to the
following text for information on individual functional categories and there functions.
