This command returns current state of the mobile originated and mobile terminated buffers,
and the SBD ring alert status.
Command Response:
+SBDSX: <MO flag>, <MOMSN>, <MT flag>, <MTMSN>, <RA flag>, <msg waiting>
where:
<MO flag>: The MO flag indicates the existence of a message in the mobile originated buffer.
The response from the A3LA-RS is one of the following numeric codes:
0
No message in mobile originated buffer
1
Message in mobile originated buffer
<MOMSN>: The MOMSN identifies the sequence number that will be used during the next
mobile originated SBD session.
<MT Flag>: The MT flag indicates the existence of a message in the mobile terminated buffer.
The response from the A3LA-RS is one of the following numeric codes:
0
No message in mobile terminated buffer
1
Message in mobile terminated buffer
<MTMSN>: The MTMSN identifies the sequence number that was used in the most recent
mobile terminated SBD session. This value will be –1 if there is nothing in the mobile
terminated buffer.
<RA flag>: The RA flag indicates whether an SBD ring alert has been received and still needs to
be answered.
0
No SBD ring alert
1
SBD ring alert has been received and needs to be answered
Note:
The RA flag is set whenever the A3LA-RS receives an SBD ring alert; this happens even if
the +SBDMTA setting specifies that SBD ring indications are disabled.
The RA flag is cleared only on successful completion of an SBD mailbox check, i.e. an SBD
session invoked with +SBDI[X[A]] in which the returned MT status indicates that no error
occurred.
The value of the RA flag is stored in non-volatile memory so it is preserved across power cycling
of the A3LA-RS.
<msg waiting>: The message waiting flag indicates how many SBD mobile terminated
messages are currently queued at the gateway awaiting collection by the A3LA-RS. This flag is
updated after every SBD session, including +SBDI, +SBDIX, +SBDIXA, +SBDREG and
+SBDDET.
