NOTE 1: If the MGC uses an IP Realm Identifier (ipdc/realm) property exceeding the maximum length limitation defined in ITU-T Recommendation H.248.41 [8], the MG shall reply with an error descriptor using error code #410: "Incorrect identifier".

NOTE 2: The MODIFY command is listed due to the fact that subsequent Streams may be "added" by MODIFY requests in case of multi-Stream-per-Termination structures. The subsequent Streams shall then carry the same IP Realm Identifier (ipdc/realm) property value as the very first Stream.

NOTE 1: When the MG is overloaded, overload Events may be sent either only following the first ADD.request which creates a new Context, or following all ADD.request commands (see ITU-T Recommendation H.248.11 [13] Corrigendum 1).
These two options result in different normalisations of the overload event rate as an indicator of the level of MG overload.
