Multi-Tech Systems, Inc. AT Commands for EDGE Modems (S000371B) 32
<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. This is the powerup default value of this
parameter; it 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 20.4, 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.
<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.
5.....36000 (default is 20)
<rba> Allowed Radio Band(s)
The parameters <rba>, <rbp> and <rbc> allow the subscriber to set and query preferences for selecting
frequency bands.
Before changing <rba> or <rbp> ensure that no network activity occurs. The write command cannot be
executed when making a call or sending/receiving short messages.
Execution of the write command causes the ME to deregister from and re-register to the network, no matter
whether the selected <rbp> or <rba> setting really changes. Therefore, it is useful to have the URC “+CREG”
enabled.
The status of the SIM PIN authentication remains unchanged, eliminating the need to enter the SIM PIN again
after the change.
