where
Network service availability is equivalent to a signal strength greater than 0. The
service availability indicator provides a way for the FA to wait until the 9601 can start an
SBD session without receiving continual notifications of changes in signal strength.
:
<antind>
Control reporting of "antenna fault" indicator changes:
No "antenna fault" indicator reporting.
0
Enable "antenna fault" indicator reporting using result code
1
+CIEV:2,<value>
where
An antenna fault indicates that the antenna is not correctly attached, and in order to
protect the transmitter no more transmissions are permitted. On seeing an antenna
fault, the user should check the antenna connection; the fault will be automatically
cleared once the 9601 detects network service availability again.
Read Command:
+CIER?
Query the current indicator event reporting settings. The response is of the form:
+CIER:<mode>,<sigind>,<svcind>,<antind>
Test Command:
+CIER=?
List the supported settings. The response is in the form:
supported
+CIER:(
<antind>
Note: In
1, the DTE may miss some indicator state changes if they occur while
<mode>
the data port is reserved. However, the buffering mechanism ensures that the most
recent change for each indicator during reservation will be flushed to the DTE after
reservation; thus the DTE is always made aware of the latest state of each indicator.
Note: The DTE may initiate an SBD session even if service is unavailable; in this case,
the 9601 makes an immediate search for the network and, if successful, starts the SBD
session, otherwise the SBD session fails.
