<groid> Ring on incoming GPRS IP data packets
This parameter can be used to control the behavior of the RING line for
incoming IP packets in GPRS online mode.
The parameter is local for the interface, volatile, and will not be reset by AT&F.
on If ME is in power saving mode 7 or 9 (see AT+CFUN) and hardware
flow control is in use (AT\Q3) and RTS line is inactive and there are
incoming IP packets for a GPRS context which is online, then the RING
line will be activated once, for a time which is configured by the
parameter “URC/Ringline/ActiveTime” (<urat>). The RING line that will
be used can be configured by the parameter “URC/Ringline” (<uri>).
off RING line is not activated for incoming IP packets. Default (a powerup
default value which is not stored at power down).
<map> MEopMode/Airplane: Enable/disable Airplane mode during operation
The two parameters <map> and <mapos> can be used to enable/disable the
Airplane mode. Airplane mode shuts down the radio part of the ME (PA and
receiver), causes the ME to log off from the GSM/GPRS network and disables
all AT commands whose execution requires a radio connection. A list of AT
commands supported during Airplane mode can be found in Section 21.4,
Availability of AT Commands Depending on Operating Mode of ME. The
benefit of Airplane mode is that, at locations where no RF emission is allowed
(typically airplanes, hospitals etc.), the subscriber can continue using network-
independent features rather than powering off the entire device (e.g., a PDA or
smartphone).
If the subscriber tries to use an AT command not available in Airplane mode,
the response "+CME ERROR: Unsupported AT command" is returned.
Parameter <map> allows entering or leaving the Airplane mode any time
during operation, eliminating the need to enter the SIM PIN again. It can be
used no matter whether the parameter <mapos> is "on" or "off".
Parameter <map> is global for all interfaces, volatile, and will not be reset by
AT&F.
on Activates Airplane mode and shuts down the radio part of the ME. The
URC "^SYSSTART AIRPLANE MODE" appears.
off Deactivates Airplane mode, wakes up the radio part of the ME and
restores access to network-dependent AT commands. The URC
"^SYSSTART" appears. Default (a powerup default value which is not
stored at power down).
<mapos> MEopMode/Airplane: Airplane mode upon ME restart
There are two ways to enter Airplane mode upon restart:
1 One is using AT^SCFG with <mapos> as described below.
2 Another approach is configuring the ME to restart into Airplane mode at a
scheduled time. In this case, use the AT+CALA command, set an alarm
time and then switch the ME off. When the alarm time is reached the ME
wakes up to Airplane mode, whether or not <mapos> was set "on" or "off".
Parameter <mapos> is global for all interfaces, non volatile, and will not be
reset by AT&F.
on Causes the ME to enter the Airplane mode each time the ME is
restarted or reset.
After restart or reset, the URC "^SYSSTART AIRPLANE MODE"
appears and parameter <map> is "on". The SIM PIN can be entered
using the AT+CPIN command. This enables the ME to read data from
the SIM and give access to SIM PIN dependent AT commands which
are available in Airplane mode, such as phonebook commands or
several SMS commands. To notify the user when SIM data are
accessible it is recommended to activate the "^SSIM READY" URC and
store its presentation mode to the user profile with AT&W.
To return from Airplane mode to Normal mode set the parameter <map>
to "off" as described above. If PIN authentication was already done, the
ME will try now to register to the GSM network.
off Airplane mode will not be activated after ME restart or reset. Default
(This is a powerup default value of a parameter which is not stored at
power down).
