A3LA-RG-reported values:
16
Modem has been locked and may not make SBD calls (see +CULK command)
17
Gateway not responding (local session timeout)
18
Connection lost (RF drop)
19
Link failure (A protocol error caused termination of the call)
20..31 Reserved, but indicate failure if used
32

This instructs the GSS to disable (detach) SBD ring alerts for the calling A3LA-RG. Successful
completion of the detach command implies that the GSS has performed the requested detach
action and the A3LA-RG is no longer registered for SBD ring alerts. This session does not
transfer any MO or MT messages.
Note: A user can send an MO-SBD message and request a detach at the same time by using
the +SBDI command. The +SBDI command always requests a detach.
A.8.105 +SBDI – Short Burst Data: Initiate an SBD Session
Note: The +SBDI command is provided for backwards compatibility with existing DTEs which
do not use SBD Ring Alert functionality. For SBD calls invoked with this command:
The SBD session type is fixed at type 0 – MO call
The SBD Delivery Short Code will be the value specified by the +SBDDSC command
An SBD Detach is performed as part of the call
No SBD location update is performed
DTEs requiring SBD Ring Alert functionality should use the exSBDIX command.
Exec Command: +SBDI
This command initiates an SBD session between the A3LA-RG and the GSS. If there is a
message in the mobile originated buffer it will be transferred to the GSS. Similarly if there is
one or more messages queued at the GSS the oldest will be transferred to the A3LA-RG and
placed into the mobile terminated buffer.
The message, if any, in the mobile originated buffer will be sent from the A3LA-RG to
the GSS
If there is a message queued at the GSS it will be transferred to the A3LA-RG and
placed into the mobile terminated buffer
Command Response:
+SBDI:<MO status>,<MOMSN>,<MT status>,<MTMSN>,<MT length>,<MT queued>
where:
<MO status>: MO session status provides an indication of the disposition of the mobile
originated transaction. The field can take on the following values:
0
No SBD message to send from the A3LA-RG
