Not supported by the "01", "02", "03", "52", "62", "63", "68", "83" product versions.
In the event of a power supply outage (i.e. main supply interruption, battery removal, battery voltage
below a certain threshold), the cellular module can be configured to send an alarm notification to a
remote entity after a trigger by a properly configured GPIO pin. The alarm notification can be set with
an AT command.
For the detailed configuration description, see section
and the u-blox AT commands manual
+ULGASP commands.

Smart radio coverage manager
☞
Not supported by the "01", "02", "03", "52", "62", "63", "68", "83" product versions.
Smart radio coverage manager is a feature that aims to reduce the power consumption in those
cellular scenarios where the radio coverage or the network conditions would cause an inefficient use
of the power supply. If the feature is enabled, when the device cannot get a reliable network coverage
or is not reachable for CS services for a user defined time interval, the cellular functionality is
automatically switched off and, after a user defined delay, re-enabled to react to possible changes in
radio coverage conditions.
For the detailed description, see the u-blox AT commands manual
, +UDCONF=57 AT command.

In-Band modem (eCall / ERA-GLONASS)
☞
Not supported by supported by the "01", "x2", "63" and "68" product versions.
LISA-U2 module supports an In-Band modem solution for eCall and ERA-GLONASS emergency call
applications over cellular networks, implemented according to the 3GPP TS 26.267
, BS EN
16062:2011
and ETSI TS 122 101
specifications.
eCall (European) and ERA-GLONASS (Russian) are two initiatives to combine mobile communications
and satellite positioning to provide rapid assistance to motorists in the event of a collision,
implementing automated emergency response system, based respectively on the corresponding GPS
and GLONASS positioning systems.
When activated, the in-vehicle systems (IVS) automatically initiate an emergency call carrying both
voice and data (including location data) directly to the nearest Public Safety Answering Point (PSAP)
to determine whether rescue services should be dispatched to the known position.
