I have been studying the Hithachi state tables, http://www.oasis-open.org/apps/org/workgroup/ws-rx/email/archives/200511/msg00183.html, and am currently creating a corresponding set of state charts which express the same information. I have a few High level comments regarding the Hitachi State Tables to stimulate discussion on this email list : 1) In the RMS state table for the "terminated" state column, it shows the RMS transmiting sequence related faults. When would the RMS be required to transmit such Faults back to the RMD for a terminated sequence? 2) We need to address all of the boxes in the Hitachi contribution which have a "?" as contents. As I am working to make the state chart diagrams, I have been thinking of some answers to these question boxes. We all should look at the these ? boxes. such faults? I am impressed with the Hitachi Contribution, and expect we will have a better spec after we answer all these questions.
