Archiving Analog & Digital Audio for Railway Application
Unified archiving of analog and digital audio communications 
"What happened? What did he say?" "I’m not sure." "Oh, no."
This might be acceptable in everyday conversation, but not when it comes to the
communications of large commercial outfits. Having recordings protects everyone in the case of major
incidents. Being able to analyze problems and miscommunications and then discuss possible ways to
resolve the issue is invaluable.

One major stumbling block to this is the mix of analog phone communications and modern
digital communications. This case study looks at the equipment that was chosen to bring
together and record all the analog and digital communications in a major railway.
