Reserve of Red LEDs

[colin_mcgeechan]

I've been told that in telecom related equipment the red LED indicates a 
particular alarm. Can someone help me here with more specific information, such 
as industry or international standards which identify the use of red for some 
error condition? (Any such "official" information would be helpful.)
     
     Many thanks,
