CSU Status
Indicates the status of the network interface located in
the unit base. These LEDs show the same indication
as the DSU and Module, with the addition of the Error
LED. The Error LED indicates an error such as BPV,
XSOs, or CRC error.
Operation Keys

Used in the DS0 mapping menu operations to copy the
last data entered into the current DS0. This key
operates without pressing the Shift key.
Remote

Home
Used to return home to the Main menu from any
menu location. This is the same as pressing Cancel
multiple times until the Main menu screen is reached.

Used as quick access to the active alarm display
menus. This can be activated while any other menu
item is in use. When the Alarm menu is exited, the
unit returns to the location of the same menu that was
active when Alarm was selected.
Shift
When pressed and held, causes the shift functions
(identified above the keys) to be activated.
Clear
Used in various menus to clear data/result fields.
Cancel
Cancels the last operation or exits the current menu
level to the next higher level. If a value on a menu
was selected but not entered, Cancel terminates the
function and restores the previous setting.
