The multimedia information control and exchange isn¡¯t needed in fact, but
in some cases, the multimedia information control and exchange still
works. For example, three terminals in a five-endpoints conference leaves,
but the conference still continues, the multimedia information control and
exchange still is needed though only the two terminals in this conference.

following is the propositional modification text :
There are two types of terminal:
¨C Hard terminal, which includes two sub-type of terminals:
dedicated studios equipped for multimedia conferences, named special
conference terminal; equipment only part-time used for teleconferencing,
can be moved from here to there, named Portable Terminal
¨C Soft terminal, running on Computer

since the function of "Voice/Video/Data Switch & Process function" is
mainly about media processing, so my suggestion to this problem is another
¡°gateway function¡± is added for the PSTN and IP transition, also for the
mobile.
