• If multiple displays of identical list configurations occur, this happens because of intermediate states of the
list, that have already been overridden by new transitions and states. Thu s, it is guaranteed that the configu-
ration displayed in such cases is the current configuration at the time of the last display.
• It is adviseable to receive URC "^SLCC" on an interface that is not used for call initiation, if verbose output is
configured. If only voice calls are expected, a setting of AT^SM20= 0 may be used alternatively in ord er to
keep the call from blocking the interface.
