An error occurred while attempting to perform a mailbox check or receive a
message from the GSS
<MTMSN>: The Mobile Terminated Message Sequence Number (MTMSN) is assigned by the
GSS when forwarding a message to the A3LA-RS. This value is indeterminate if the field <MT
status> is zero. This wraparound counter can range from 0 to 65535.
<MT length>: The MT length is the length in bytes of the mobile terminated SBD message
received from the GSS. If no message was received, this field will be zero.
<MT queued>: MT queued is a count of mobile terminated SBD messages waiting at the GSS to
be transferred to the A3LA-RS.
A.8.107 +SBDDSC – Short Burst Data: Delivery Short Code
Set Command:
+SBDDSC=<dsc>
Set the Delivery Short Code (DSC), which provides dynamic routing or control information for
MO or MT messages. This is an 8-bit value providing the ability to set individual fields. Value
0x80 (hexadecimal) sets the most significant bit. Value 0x01 sets the least significant bit. Flag
values can be added together to achieve a combination of settings. Some fields are overridden
during certain SBD sessions (e.g. a +SBDREG registration session sets flag 0x80).
Enable or
disable ring indications for SBD Ring Alerts.
<dsc>:
0..255 DSC to be used for subsequent MO messages (0 default)
0x80 Hold MT message delivery
0x40 Leave MT message in queue after delivery
0x20 Destination in MO payload
