TCAS is rather the US name for it while ACAS came from EASA (i.e. JAA).
Since the American where first (well, they mostly are...), sometimes TCAS is also referred to TCAS I and II. ACAS is mostly considered TCAS II.

TCAS Bulletins
Check out this link to Eurocontrol.
On the bottom of the page you will find links to 9 very well written bulletins, from daily practice in European airspace.
http://www.eurocontrol.int/msa/publi...html#Bulletins
If above link fails, because it right away delves too deep, then try the one below. On the bottom of that page you will find a link to the bulletins (the link given above).
http://www.eurocontrol.int/msa/publi.../homepage.html
If this link fails as well, try simply eurocontrol.int and search for the subject "msa", that should take you to the subsite.
Good luck.

my understanding is that TCAS is a brand name for the generic ACAS (much like Hoover is for vacuum cleaner). When ACAS first appeared on the scene the only real contender was TCAS and hence the name has stuck.
I have no references for this, it's purely what I've been told over the years.

ACAS is the acronym for the standard set by the authority.
TCAS is the acronym for the Rocwell/Collins system (and currently the only one?) that meets that standard.

That makes things easier to understand! When we get a 'TCAS fail' on the EFIS (because that is the brand name used by Rockwell), there is no mention of it in the MEL, only ACAS (which is the generic name for the system).
