Product Code:SAE AS4074
Title:Linear Token Passing Multiplex Data Bus (NONCURRENT Oct 2004)
Issuing Committee:As-1a Avionic Networks Committee
Scope:This standard specifies the characteristics of the SAE Linear Token Passing Bus (LTPB) Interface Unit. The LTPB provides a high reliability, high bandwidth, low latency serial interconnection network suitable for utilization in real time military and commercial applications. Multiple redundant data paths can be implemented to enhance reliability and survivability in those applications which require these attributes. The token passing and data exchange protocols are optimized to provide low latency and fast failure detection and correction. Physical configurations with bus lengths up to 1000 m can be accommodated.
