1)     Greetings! (5 min; 9:30-9:35)

2)     Review decisions made at last meeting (30 min; 9:35-10:05).

Discussion of Bombardier “difficulties” with conforming to the IEEE WG9 P1544.  One drawback is the lack of services defined by UIC 556 for coach-to-coach communication.  Chris Holliday stated that NJT would be willing to wait to ensure IEEE compliance on Comet V.

Actions:

NJT to send IEEE docs to Bombardier Zurich.

NJT to arrange a meeting between IEEE and Bombardier Zurich to discuss IEEE/Comet V “merging.”

3)     Recent developments.

a)     Comet V/ALP 46 (15 min; 10:05-10:20).

See above.

b)     LonMark (15 min; 10:20-10:35).

WTB-to-Lon Gateway discussion.  PDM needs to be developed for WTB to Lon; this was agreed.  EKE has implemented this already in their gateways and states that it is not difficult to do.

Concern about boxing in functionality by standardizing.  My point is that this is a fundamentally philosophical issue and applies to all standardizing efforts, not just this one.  Isabelle stated that the IEEE needed to ensure that this standard is not just for Comet V.

Discussion of LonMark Transportation Group activity.  WG9 needs to start having joint meetings with the LonMark association; also with WG3.  Next meeting of LonMark will be set to coincide with the RTVISC meeting.  Also combine WG9 and WG3?

c)      Next RTVISC meeting (5 min; 10:35-10:40).

Next meeting is tentatively scheduled for January 9 & 10, 2002, at MUNI.  However, it was reported that NYCT employees are prohibited from traveling by air anywhere.  Since Stanley Kwa of NYCT needs to be at the meeting, this may affect the location.

Use of UIC 556 was discussed.  Are there any copyright concerns?

4)     PAR renewal (15 min; 10:40-10:55).

It is agreed that the PAR should be amended to expand the scope.

5)     Discussion of status of standard gateway project.

a)     Gateway specification (15 min; 10:55-11:10).

This has been updated and will be disseminated.

b)     APTA participation (15 min; 11:10-11:25).

NJT is holding things up; APTA is basically ready to go.

c)      NJT participation (15 min; 11:25-11:40).

This is critical.  Chris Holliday has been trying (and will continue to try) to get the required commitment from NJT.

d)     Supplier participation (15 min; 11:40-11:55).

Interest in this is not as great among the suppliers as it was in July.  ALSTOM has lost interest since the Comet V gateway (two step) is allowed in the NJT spec for the multi-level coaches; Microsym/Oerlikon has lost interest since EKE already has a gateway developed.  Also, the 500 ms point-to-point time response requirement and TWC requirement is not compatible with the WTB-Lon gateway, since large file transfers are needed.  Lon is more important for the doors, brakes, ATC, HVAC; the gateway doesn’t have to control any Lon-based US system directly.

6)     Review of draft standards.

a)     P1544-1- Data element definitions (30 min; 11:55-12:25).

7)    Lunch (65 min; 12:25-1:30).

8)     Review of draft standards (cont.).

a)     P1544-1- Data element definitions (60 min; 1:30-2:30). (see doc markup)

b)     P1544-2- R-Telegrams (30 min; 2:30-3:00). (see doc markup)

c)      P1544-3- E-Telegrams (30 min; 3:00-3:30).

9)     Next Actions.

a)     WG3 coordination (15 min; 3:30-3:45).

b)     Other (30 min; 3:45-4:15).

10)Wrap-up (15 min; 4:15-4:30).

11)Next meeting (5 min; 4:30-4:35).
