<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.
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 which will be used, can be
configured by the parameter "URC/Ringline" (<uri>).
"off" RING line is not activated for incoming IP packets. Default.
<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.
<mapos> MEopMode/Airplane: Airplane mode upon ME restart
There are two ways to enter Airplane mode upon restart: One is using AT^SCFG with <mapos> as described
below.
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, no matter whether <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.
<psm9to> Power Saving Mode 9 Timeout
This parameter can be used to query or configure the wake up time for power saving mode 9 (see AT+CFUN
with parameter <fun>=9). The granularity of the timeout value is 100ms (i.e. a value of 10 equal 1 second).
The minimum timeout value that can be applied is 5, but accuracy is only guaranteed for timeout values
greater than 20.
Parameter is global for the ME, volatile and will not be reset by AT&F.
