Embedded LAPB Protocol Stack
TargetLAPB from Blunk Microsystems is a full-featured ISO/IEC 7776 compliant
LAPB protocol stack for use in embedded applications. TargetLAPB supports
both RTOS and polling environments.
Programmable Window Size
Multiple HDLC Channels
Reliability and Flow Control
LAPB Protocol Decoder
LAPB Test Set
TargetLAPB supplies an easy-to-use application program interface for
exchanging frames of data on a point-to-point network. It is an advanced
implementation supporting delayed acknowledgements, programmable window
size, extended sequencing, and multiple HDLC channels. Window size, DCE or
DTE addressing, and parameters T1, T2, T4, and N2 are programmed
independently for each channel. LAPB events, such as channel disconnect, are
reported to the application layer through a callback function installed
during initialization. TargetLAPB's protocol decoder prints a complete
decode of every frame transmitted or received.
TargetLAPB is Site licensed and includes source code, sample applications,
and technical support. Distribution of executable code is royalty-free.
Blunk Microsystems also provides a Hardware/Software LAPB test set solution,
The BlunkBoxTM. BlunkBox is designed to exercise the HDLC, LAPB, and
application software of products containing a LAPB connection. Based on a
single board computer, BlunkBox is used for both engineering development and
manufacturing test. BlunkBox uses one RS-232 connection for the
terminal-based user interface and two RS-422/RS-530 synchronous connections
for LAPB/HDLC testing.
Together, TargetLAPB and the BlunkBox will significantly reduce your
development cycle, and help you get your product to the market quickly.
