A low level of the V180 signal - in addition to the regular "^SHUTDOWN" URC issued by the
module - indicates that the switch off procedure has completed and the module has entered
the Power Down mode.
Note: Using the command AT^SMSO=”fast”, it is possible to trigger a fast shutdown procedure,
i.e., shutting down without gracefully deregistering from the network thus saving time between
T0 - T2. Same as with the fast shutdown procedure triggered with the FST_SHDN line (see
Section 2.1.11.3), there will be no ^SHUTDOWN URC in this case. The timings for module
switch off using AT^SMSO=”fast” are listed below in Table 16.
