That was my first reaction too. But I think Ty meant that CMIP
was called CMOT in an IP environment.

Actuall the standards do not describe management information but
define in which way management information should be defined.

Also CMIS/P is used in the TMN environment which is defined in
CCITT recommendation M.3010. Here CMIS/P is used on the so called
Q-interfaces. TMN (Telecommunications Management Network) is used
for managing telecommunications network.

A number of CCITT recommendations define management information
for different technologies like SDH (G.774) and SS#7 (Q.751).
There are others but I don't know the relevant CCITT
recommendations.

Now that we are on the subject. Does anyone feel the need for a
newsgroup about TMN and OSI management? If more of you think such
a group is usefull we could start an RFD for it. Please let me
know your opinions, preferably by email and I will post a summary
later.
