Acquiring/Releasing the User Interface
You can access the user interface from either the front panel, the COM port, the
MODEM port (for standalone CSUs), or the SDCP (for carrier-mounted CSUs).
The CSU allows only one user interface to be active at a time. The front panel is
the default user interface at power-on 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.
The inactive interface displays the following message when a Function key is
pressed or a connection is made on the inactive user interface and control cannot
be switched because the currently active interface is in use. On the screen, either
Ft. Panel (front panel), Com Port, Modem, or SDCP is displayed in the user
interface (
User I/F ) field.
