Erratum
Description of Correction to
address Erratum
Change
Request
Reference
In the SMPP Protocol Specification
v3.4. version 30-July-1999 Issue 1.1
section 4.1.5 “Bind_Transceiver”
the interface_version field was
inadvertently not included in the
bind_transceiver PDU.
The erratum was corrected in the
SMPP Protocol Specification v3.4
version 12-Oct-1999 Issue 1.2 as
follows:
In section 4.1.5 “Bind_Transceiver”
the interface_version field was
added as a mandatory field to the
bind_transceiver PDU.
Since it is a mandatory field all
implementations of the SMPP
Protocol Specification v3.4 must
include the interface_version field
when using the bind_transceiver
PDU.
