Confidential / Released
Unsolicited Result Codes
URC 1
^SYSSTART
Indicates that the ME has been started and is ready to operate. If autobauding is active (AT+IPR=0) the URC
is not generated.
If the ME is configured to enter the Airplane mode after restart or reset the following URC is received on boot-
up: "^SYSSTART AIRPLANE MODE". In this mode, only the AT commands listed in Section 23.4, Avail-
ability of AT Commands Depending on Operating Mode of ME can be used. For details please
refer to the AT^SCFG command, parameter <mapos>.
URC 2
^SYSSTART CHARGE ONLY MODE
Indicates that the ME has entered the CHARGE ONLY mode. This occurs if the charger is connected while
the ME is in POWER DOWN mode. If autobauding is active (AT+IPR=0) the URC is not generated. In
CHARGE ONLY mode the ME is neither registered to the GSM network nor are the serial interfaces fully
accessible. Only the AT commands listed in Section 23.4, Availability of AT Commands Depending
on Operating Mode of ME can be used. For further details on charging refer to the Hardware Interface
Description [2].
Parameter Description
0 NON-CYCLIC SLEEP mode:
In this mode, the AT interface is not accessible. Consequently, after setting
<fun>=0, do not send further characters. Otherwise these characters remain
in the input buffer and may delay the output of an unsolicited result code.
Due to the fact that the serial interface is disabled, this mode cannot be used
if a Remote SIM Access (RSA) connection is ongoing (reason: during RSA
connections the SIM communication is routed via a serial channel).
The first wake-up event stops power saving and takes the ME back to full func-
tionality level <fun>=1.
[1](&F)(P) Full functionality (no power saving).
If the ME is in one of the CYCLIC SLEEP modes you can issue AT+CFUN=1
to stop power saving and return to full functionality. If the ME is NON-CYCLIC
SLEEP mode, <fun>=1 can also be sent by the Java application.
Keep in mind that, unlike the reset command described below, this action does
not restart the ME but only changes the level of functionality. See parameter
<rst> for details on the reset.
7 CYCLIC SLEEP mode:
In this mode, the serial interface is shortly enabled while CTS is active. If char-
acters are recognized on the serial interface, the ME stays active for 2 seconds
after the last character was sent or received.
The ME exits SLEEP mode only, if AT+CFUN=1 is entered.
9 CYCLIC SLEEP mode:
In this mode, the serial interface is shortly enabled while CTS is active. If char-
acters are recognized on the serial interface, the ME stays active after the last
character was sent or received for at least the time, which can be configured
by AT^SCFG="PowerSaver/Mode9/Timeout",<psm9to> (temporary wakeup).
In contrast to SLEEP mode 7 assertion of RTS can also be used to temporarily
wake up the ME. In this case too, activity time is at least the time set with
AT^SCFG="PowerSaver/Mode9/Timeout",<psm9to>. RTS can be activated
either from ASC0 or ASC1.
The ME exits SLEEP mode only, if AT+CFUN=1 is entered.
