4 Requirements for C&I The C&I functions are defined such that, under various appropnate circumstances, the audiovisual system will opérate in a fauH-free manner and also such that sympathetic presentation to users is possible. Some functions must therefore be mandatory, others optional. This section, together with the categorization in Table 1/H.230, clarines the circumstances under which C&I functions are mandatory. CM denotes "conditionally mandatory": if the terminal (or MCU) is capable of entering the given state, then it must transmit the given code and, when leaving that state, the complementary code. If it has no such capabiiity it can ignore both. M denotes "mandatory" for all equipments of either terminal or MCU type. X denotes "non-mandatory": on receipt of such a code, it may be unrecognized, or recognized but not acted upon, or recognized and acted upon, entirely at the discretion of the manufacturer or NA denotes that the code is not applicable in that case. It will be noted that there are only a few mandatory requirements on most terruinals. All audiovisual termináis must recognize and obey the command to make or break the digital loopback, and video loopback if they have video capabiiity. All termináis having a video capabiiity must also obey fast-update, freeze-picture, and MCS/MCN, otherwise there will be system misoperation on a multipoint cali.
