(S800T)
Working Group website

Chair and webmaster is Michael D. Johas Teener
Secretary is Les Baxter of Baxter Enterprises

(p1394c passes first ballot, important information below)

What is p1394c?

This is a full-use standard whose scope is to provide an amendment to IEEE Std 1394-1995TM, IEEE Std 1394a-2000TM and IEEE Std 1394b-2002TM that defines features and mechanisms that provide gigabit speed using catagory 5 cabling over single hop distances of up to 100M. The following are included in this amendment:

  1. Automatic negotiation that allows a port to connect using either the IEEE Std 1394 or IEEE Std 802.3 higher layers;
  2. An updated beta port specification that provides easy connection with the same PHY specified in IEEE Std 802.3 clause 40; and
  3. Various minor updates to IEEE Std 1394b-2002TM.

Kevin Brown of Broadcom has prepared a short summary of p1394c technology.

Communication

The working group does most of its work via email on the 1394 standards reflector. Non-members cannot send to the reflector, you must first send "subscribe stds-1394 your-real-name" to "listserv@listserv.ieee.org" and wait for the challenge/response anti-SPAM process ...

Schedule

There are no further meetings planned. All technical issues have been resolved and a ballot-ready draft is in preparation.

All following meetings will be ballot review committee work to incorporate comments and suggestions received during balloting.

Document status

The P1394c sponsor ballot closed on March 30th, 2006, with the following result:

  • 52 affirmative votes
  • 3 negative votes with comments
  • 0 negative votes without comments
  • 3 abstention votes

58 votes received = 81% returned, 5% abstention

Approval Rate

  • 52 affirmative votes
  • 3 negative votes with comments
  • 55 votes = 95% affirmative

There were a total of 58 comments - 16 technical, 6 general and 43 editorial.

The negative votes with comments furnished a total of 9 technical comments that the respective balloters indicated must be satisfied.

BRC

The BRC has been appointed and comprises

  • Les Baxter
  • Kevin Brown
  • Michael Johas Teener
  • Colin Whitby-Strevens

Given the relatively few comments, and their nature, the BRC has adopted an aggressive schedule for resolving the comments and initiating a recirculation ballot by April 24th, and making a submission to RevCom by the IEEE deadline of April 28th (I understand that under the IEEE rules this is in order, provided that the recirculation ballot has been initiated), thus allowing final approval to be considered at the Standards Board meeting on June 8th.

The first meeting of the BRC is scheduled for Wednesday April 12th.

Current draft
(password protected)

The last draft before balloting was p1394c draft 0.4 (thank you very much, Colin!). This draft has been renamed as draft 1.0 with minor changes and is up for IEEE ballot.

A zipped archive of the FrameMaker sources of all previous drafts is available here.

Note that all draft standards are password protected. This is IEEE policy. The password is only available to participants in the 1394 standardization process (in effect, this means those that are on the stds-1394 reflector).

Source code

The normative description of the protocols used in all 1394 standards is done in c-language files that are embedded within the document. For 1394c, these are available separately as a zip-compressed file. The current version was created on July 5, 2005, and is maintained by Colin Whitby-Strevens .
