The temperature thresholds are defined in Table 60.
Symbol
Parameter
Temperature
Remarks
t
-2
Low temperature shutdown
–40 °C
Equal to the absolute minimum temperature rating for the cellular
module (the lower limit of the extended temperature range)
t
-1
Low temperature warning
–30 °C
10 °C above t
-2
t
+1
High temperature warning
+77 °C
20 °C below t
+2
. The higher warning area for the upper range
ensures that any countermeasures used to limit the thermal
heating will become effective, even considering some thermal
inertia of the complete assembly.
t
+2
High temperature shutdown
+97 °C
Equal to the internal temperature Ti measured in the worst case
operating condition at typical supply voltage when the ambient
temperature Ta in the reference setup (*) equals the absolute
maximum temperature rating (upper limit of the extended
temperature range)

☞ The sensor measures the board temperature inside the shields, which can differ from the ambient
temperature.
3.17 Bearer Independent Protocol
☞ Not supported by the "01", "x2", "63" and "68" product versions.
The Bearer Independent Protocol is a mechanism by which a cellular module provides a SIM with
access to the data bearers supported by the network. With the Bearer Independent Protocol (BIP) for
Over-the-Air SIM provisioning, the data transfer from and to the SIM uses either an already active PDP
context or a new PDP context established with the APN provided by the SIM card.
For more details, see the u-blox AT Commands Manual [2].
3.18 Multi-Level Precedence and Pre-emption Service
☞ Not supported by the "01", "x2", "63" and "68" product versions.
The Multi-Level Precedence and Pre-emption Service (eMLPP) permits to handle the call priority. The
maximum priority associated to a user is set in the SIM: within this threshold, the user can assign
different priorities to the calls. This results in a differentiated treatment of the calls by the network in
case of abnormal events such as handovers to congested cells.
For more details, see the u-blox AT Commands Manual [2].
3.19 Network Friendly Mode
☞ Not supported by the “01", "x2", "63" and "68" product versions.
The Network Friendly Mode (NFM) feature provides a more efficient access to the network since it
regulates the number of network accesses per service type over a configurable amount of time,
avoiding scenarios in which the cellular module continuously retries a registration or a PDP context
activation procedure until it is successful. In case of appropriate network rejection errors, a back-off
timer can be started: when the timer is running or the number of allowed accesses is reached, further
attempts are denied and an URC may be enabled to indicate the time remaining before a further
attempt can be served. The back-off timer controls the temporal spread of successive attempts to
register to CS or PS services, to activate a PDP context and to send SMS messages.
For more details, see the u-blox AT Commands Manual [2].
