However, their long-term future will continue to be threatened by end-of-life (EOL) of crucial subsystems and components such as the TSI148 VME-to-PCI bridge chip that’s been at the heart of VME adapter (carrier) boards. Some VME suppliers have left it up to their customers to address these EOL problems on their own. But for end users, dealing with VME platform issues is at best an engineering distraction. At worst, it requires them to decommission perfectly adequate VME systems and commit to the enormous expense of purchasing more up-to-date systems and porting legacy application programs to them.

Within a few years it became a standardized bus in Europe and North America (ANSI/IEEE 1014-1987). Since then, designers at military and civilian avionics suppliers have used the VME architecture in thousands of test and simulation systems, and many of these systems require [MIL-STD-1553 and ARINC 429 avionics bus interfaces](https://info.aviftech.com/rfi-vme)..

With shared data busses like MIL-STD-1553 and ARINC 629 monitoring equipment could easily access all avionics system data from a single connection to the shared bus. With switched networks there is no signle connection point with access to all data.
