(speaking as a contributor and co-author of RFC 3877) Our intention with ituAlarmTable was stated in 4.1.3 > Optionally, ituAlarmPerceivedSeverity models the states in terms of ITU perceived severity. and then in 5.1: > The ituAlarmTable contains information from the ITU Alarm Model about possible alarms in the system. My recollection is that we did not seek exact emulation, but a mapping that makes sense for the severity levels. We looked at the ITU-T standards because we did not want to reinvent the wheel. I personally was not aware about the differences between M.3100 and X.733 on this respect, but frankly I was relying on Sharon who was at that time directly involved in the ITU-T work.
