Chapter 3 – Status Control Commands
Multi-Tech Systems, Inc. AT Commands for EDGE (E1) Modems (S000474A) 49
Parameters:
<indValue> Integer type value, which shall be in range of corresponding <indDescr>
<indDescr> String values and their <indValue> ranges.
More indications are available via AT^SIND. Therefore use of AT^SIND for
control of all indications is recommended.
The following indications are accessible via AT+CIND:
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 estimated
values. See 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 network
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 output 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).
0 Signal strength <= -112 dbm
1-4 Signal strength in 15 dbm steps
5 Signal strength >= -51 dbm
99 Not known or not detectable
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>
0 Indicator is deregistered. The indicator will not be presented as
“+CIEV” URC, but can be queried with AT+CIND?.
1 Indicator is registered, indicator event report allowed. Default.
(This is the factory default value and will be restored to 1 with
AT&F. It is also a powerup default which is not stored at power
down).
Notes:
• Due to its restri
ctive value range, indicator “call” does not clearly reflect specific call states (such as alerting,
active, held etc.), but rather serves to trigger the application to retrieve the new call status from the list of
current calls with the AT commands AT^SLCC, AT+CLCC or AT^SCNI.
• If AT^SCFG setting <succ>=”verbose”, indicator “call” will be issued also when a traffic channel is established,
or when a call enters states “terminating” or “dropped” (see Call Status Information). In these cases, the
relevant information about the cause of the display is available only from AT command AT^SLCC.
• This command is not PIN protected.
• This command is available in airplane mode.
