Current Focus Definition and cataloging of data elements for

BOU interoperability. Data elements and data structures are based

on those defined in UIC 556 for TCN WTB (IEEE 1473-T train network).

Data elements defined by WG9 will be used by LonMark Transportation Group in defining functional profiles and SNVTs.

Current Status Third internal draft of IEEE P1544 is in

development. Relevant sections of UIC 556 are either

referred to or duplicated (with extensions in some cases); this requires consent of UIC.

Draft will be released as P1544/D1 and distributed by 2/5/2002.

Next meeting to review P1544 scheduled for 2/25/2002.

Revised PAR needs to be submitted.

Coordination RequirementsWG3- UIC 556 defines certain

mechanisms for diagnostics; this needs to be coordinated with WG3.

LonMark- First joint meeting held with LonMark on 1/8/2002 at Echelon in San Jose.

TWC working group.
