Digital fallback solutions for railway audio systems: the good without the bad

For a long time, audio systems have been vital for communication on trains. Digital Ethernet connections have recently expanded their capabilities, but the old standard, UIC568, hasn't adapted. When Ethernet fails, it's still used as a backup, but it has limitations.

Dual homing, a costly Ethernet redundancy option, can solve this, but there's a better, cost-efficient solution. Discover it in this white paper.
