Siemens MC55 AT manual Also refer to .1, Call Status Information

<indDescr>(str)

String values and their <indValue> ranges.

More indications are available via AT^SIND. Therefore use of AT^SIND for control of all indications is recom- mended.

The following indications are accessible via AT+CIND:

"battchg"	Battery charge level 0..4 or 5 if no measuring is performed, e.g because no bat-
	tery is connected. Also refer to AT^SBC.
"signal"	Signal quality (0..7) or (99) if not measurable
	The indicated value is the bit error rate of the signal received. Bit errors are esti-
	mated values. See also AT+CSQ.
"service"	Service availability (0-1)
	0: Not registered to any network
	1: Registered to home network or, if "roam"=1 then registered to another net-
	work
"sounder"	Sounder activity (0-1)
	Reports every event that causes the ME to generate a tone.
	Value 1 means for example:
	Incoming call - ME is ringing. Note that the URC "+CIEV: sounder" will be out-
	put only if ringing tones are activated with AT^SRTC.
	Waiting call - ME generates waiting call tone (if call waiting is enabled).
	Outgoing call - ME generates Call Progress tone.
	Outgoing call - ME generates BUSY tone.
	The value changes to 0 when the tone stops.
"message"	Unread short message at memory location <mem1> (0-1); refer to AT+CPMS
"call"	Call in progress (0-1). Indicator value is "1" if at least one call is in state "active"
	or "held".
	Depending on the parameter <succ> selected with AT^SCFG the indicator
	"call" will be issued
	• when a state transition ends in state "active" or state "unknown", if
	<succ>="restricted",
	• when any state transition (including transitions beginning or ending in state
	"unknown") occurs in the list of active calls or when a traffic channel is
	established, if <succ>="verbose".
	Also refer to Section 7.1, Call Status Information.
"roam"	Roaming indicator (0-1)
	0: Registered to home network or not registered
	1: Registered to other network
"smsfull"	A short message memory storage in the MT has become full (1) or memory
	locations are available (0), i.e. range is (0-1)
"rssi"	Received signal (field) strength (0..5) or (99) if not measurable
	0: signal strength <= -112 dbm
	1-4: signal strength in 15 dbm steps
	5: signal strength >= -51 dbm
	Received signal (field) strength can also be obtained with AT+CSQ. However,
	the signal strength is scaled to value range 0..31 by this command.
<mode>(num)
0	Indicator is deregistered. The indicator will not be presented as "+CIEV" URC,
	but can be queried with AT+CIND?.
[1](&F)(P)	Indicator is registered, indicator event report allowed.
