LCD
The LCD is used to display two types of data:
Messages such as alarms, command/test completion, and action in progress
SDCP menu tree information (see Appendix A,
SDCP Menu
)
The LCD displays status messages as requested via the Device Health and
Status branch of the SDCP menu (see
Device Health and Status
in Chapter 4,
Monitoring and Testing
). In addition, the highest level status message appears on
the front panel automatically if no front panel action has occurred at the
DSU/CSU for the past five minutes.
The LCD also lists commands, configuration options, and test results. In most
cases, the top line shows the command or option name and default value, while
the second line displays options and responses. When a response is required,
select from the options displayed directly above the Function keys (F1, F2, F3);
make your choice by pressing the corresponding Function key.
Keypad
The 7-button keypad enables you to navigate through the menu tree and select
choices presented on the second line of the LCD.
