Acquiring/Releasing
the User Interface
You can access the user interface from either the front
panel, the COM port, or the MODEM port. The
DSU/CSU allows only one user interface to be active at a
time. The front panel is the default user interface at
power-up or after a reset. It is also the default during a
software download or when a failure occurs at either the
local or remote PC interface.
You can switch an inactive user interface to active if,
• The current active user interface has had no activity
(no key was pressed) for at least five minutes.
• The active user interface has been released with the
Release command.
• The active interface connection is broken. This
includes the call disconnect for a modem interface
or the termination of the front panel emulation
program on a locally-attached PC (if the PC
supports DTR) or the termination of the async
terminal interface on a remote or locally-attached
terminal.
Acquiring the Active User Interface
To acquire the active user interface, press any key. If
you are using the PC interface, use the mouse to click on
the desired Function key.
The top-level menu screen appears on the active user
interface, regardless of what screen was displayed at the
previous active user interface.
