Acquiring/Releasing the User Interface
You can access the user interface from either the front panel, the COM port, the
MODEM port (for standalone DSU/CSUs), or the SDCP (for carrier-mounted
DSU/CSUs). 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.
