1149.5: now it's a standard, so what?

The 1149.5 standard provides an extensible and robust infrastructure for the communication of test and maintenance messages within a system. This infrastructure offers many advantages over other backplane test bus solutions in terms of both its extensibility, and error handling capabilities. Since becoming a standard, 1149.5 has been gaining momentum within the electronic community and has been successfully deployed within the communication and avionics industries. The general availability of commercial 1149.5 interface devices, expected later this year will provide an emerging market for 1149.5 based products and technologies.
