No, this might seem trivial but it is not. The Q3 is an interface
whereas the reference point is called q3. (Capital Q versus little q)

The Q.xxx recommendation (can't check at home) describes protocol stacks
for the Q3 interface and not for the reference point. See also my
earlier posting for the difference between the reference point and the
interface (posted under the name of mschenk@research.ptt.nl because of a
change in posting software).

The Q1 and Q2 interfaces are not used anymore. The Qx interface is.

You should try to get hold of M.3010 which defines the entire TMN
concept. This recommendation also refers to other documents.
