IEEE Rail Transit Vehicle Interface Standards Committee
WG9 STANDARD P1544
TRANSIT COMMUNICATIONS INTERFACE PROFILES FOR RAIL APPLICATIONS
Fifth Meeting, Nov 18, 1998
MTA-NYC Transit
130 Livingston St., Brooklyn
5th Floor Conference Room
Meeting called to order at 9:10 a.m.
1.0 Welcome
Rob McHugh introduced himself and introductions continued around the table. A list of attendees is attached (Attachment 1). Max Louis-Jacques was thanked for arranging the meeting room.

2.0 Agenda and Meeting 4 Minutes
The agenda was reviewed and accepted as attached (Attachment 2). The last meeting minutes were reviewed and accepted without change.
3.0 IEEE–TCIP Co-ordination
Tom McGean updated the group on the potential working arrangements between the IEEE–RTVISC WG9 and the Transit Standards Consortium (ITE–TCIP). This arrangement will allow balloting by the Rail Community. The registration and validation of the WG9 data object database should be done at the TCIP level.
4.0 TCIP Overview and Report
The TCIP effort initiated by the Institute of Transportation Engineers, Standards for Intelligent Transit Systems, uses the NEMA hierarchical addressing convention and ASN.1 data types to create data and message object databases. The on-board object sets were of particular interest to the IEEE-RTVISC WG9 since they have rail object set placeholders. The web site for TCIP will soon be linked with the Transit Standards Consortium.
5.0 Data Object Modelling
Hubert Kirrmann of ABB Corporate Research distributed a presentation on object modelling methodology in railways. The ROSIN framework object-oriented approach meshes well with the TCIP ASN.1 model. WG9 needs to consider how to converge the bottom–up vehicle equipment approach with the top-down TCIP business unit. Rob will make Hubert’s PowerPoint presentation available.
6.0 Related Standards & Publications (OMG)
Tom McGean has established an informal working relationship between the Object Management Group (OMG) and the IEEE RVISC. Formal arrangements should be established through the TSC. The restrictions required to be placed on ASN.1 to make mapping to IDL simpler should be discussed at the TSC level.
7.0 WG9 Standard Document Structure
Wording for the PAR title, scope and purpose was accepted by the IEEE. The title was agreed as: TRANSIT COMMUNICATIONS INTERFACE PROFILES FOR RAIL APPLICATIONS. The standard will be referred to as P1544 with a draft extension. Discussions of the table of contents did not lead to any additions, however the equipment modeling technique should be explained in section 4. Also, the data dictionary will be completed before the message objects.
8.0 Entering IEEE WG Data into a Database
Microsoft Access will be the database program ( Office 97 or its predecessors ). Rob McHugh agreed to distribute the TCIP database form to facilitate the entry of their working groups’ data elements. Rob McHugh agreed to enter WG5 data elements into the database at this time. Pierre Zuber volunteered to review data elements pertaining to WG3. Joe McDermott volunteered to review data elements pertaining to WG2. Mike Barnett volunteered to review data elements pertaining to WG6. Gopendra Dash volunteered to review ATC data elements. Hubert Kirrmann volunteered to review data elements pertaining to ROSIN. All tables and Access files will be collected electronically by the chair for Dec. 15th . A unified database will be circulated by Feb. 15th.
9.0 Next Meeting
It was proposed that the next meeting be held the week of Feb.15,1998.
Rob will try to dovetail with WG1 or 3 if possible; exact date and location will be posted on
