If you think an ORC is one of those ugly buggers in the Lord of the Rings, think again. It's actually a highly reliable radio-over-IP (RoIP) system that has brought New Zealand's railway communications into the 21st century.
You've heard of applications where failure isn't an option. This is one of them. The ORC transmits all voice communications between rail vehicles and the train control center, and handles any emergency calls that a train may transmit if a derailment occurs. So it's got to run 24/7, with no excuses. To achieve that goal, it takes advantage of QNX Neutrino's dynamic upgradability and software fault tolerance.
Enough introductions. Click here and check out the ORC for yourself.
