DCC Working Group Inactive Topics

A discussion topic can become "inactive" when interest wanes before some conclusion is reached. The NMRA DCC Working Group maintains them in this list of inactive topics so that historical information is still available if the topic is later revived.

Topic 0107122 - User Defaults

This became inactive in August of 2004. No prior information was available.

Topic 0104191 - CV Table Structure Proposal

This became inactive in August of 2004. No prior information was available.

Topic 0307161 - Clarification of sequence of Multiple Protocols

An additional comment was received about command stations and decoders supporting more than two protocols (i.e. DCC, Bi-Directional, Motorola), and what order that they should be in.

After discussion at the Summer 2004 and Fall 2004 Working Group meetings and on the Working Group mailing list, it was decided to move this topic to the inactive list on September 29, 2004. No drafts or background information had been created for this topic while it was active.

Topic 0307162 - Transition Sequence for Multiple Protocols

As a corollary to Topic 0307161, a comment was received about adding a possible transition sequence before changing to an alternative protocol in multi-protocol systems. An separate proposal was received to add a requirement in S-9.2 that all multi protocol operations end with the second half of a zero bit. This improves backward compatibility and resynchronizes the DCC signal.

Due to there being nobody actively working it, this was made an inactive topic in August of 2004.

Little historical information was available.
