"unknown") occurs in the list of active calls or when a traffic ch annel is

established, if AT^SCFG setting <succ>="verbose".

Also refer 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 no t 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.

0 Indicator is deregistered. The indicator will not be presented as "+CIEV" URC,

but can be queried with AT+CIND?.

[1](P) Indicator is registered, indicator event report allowed.

Notes

• Due to its restrictive range of values, there are events when it is not entirely clear from the context, which

event has led to the output of indicator "call". Rather than as an information in itself, indicator "call" sh ould

therefore be used as a trigger to look up the new call status in the list of current calls with AT commands

AT^SLCC, AT+CLCC or AT^SCNI.

• If AT^SCFG setting <succ>="verbose", indicator "call" will be is sued also when a traffic channel is estab-

lished, or when a call enters states "terminating" or "dropped" (see chapter Call Status Information).

In these cases, the relevant information about the cause of the display is availabl e only from AT command

AT^SLCC.

• The indicator "sounder" signals every event a tone is generated in the ME. For instance, if a waiting call pro-

duces a tone, this will be indicated.

• If the ME is switched on all indicators are in registered state.

•Use

AT+CMER command to allow Indicator Event Report of all registered indicators.

Example

<state>(num)

^SYSSTART

AT+CPIN=9999

AT+CIND?

+CIND: 5,99,1,0,0,0,0,0,5

The battery is either full or no battery is connected to the ME. The bit

error rate of the signal quality is not available (since there is no call in

progress). The ME is registered to its home network.

AT+CMER=2,0,0,2

Now activate the Indicator Event Report with AT+CMER.
