TR-512.6 Equipment model v1.6 work plan

  • Start at the virtual Meeting discussing sections that need refinement
  • In May timeframe (May xx) to
    • Have a shallow section-by-section review of TR-512.6 
      • Add necessary appropriate covering note for each of the sections to indicate any further enhancement
  • This will give more time for the group to finish the other higher priority documents of TR-512.

Also discussed the presentation material in general.

To look at the presentation material (OIMT Presentations) to see if any of those provide significant material can be used in another . (dot) series of the core model. 

May want to add a cover slide that disclaims the material. May want to add a watermark on each slide to indicate the informal nature. 

Kam/Nigel to review repository for relevant material as candidate to be published in  the deliverable.

TR-512.8 Control


Further discussed the multiplicities of the association ends among the object classes ControlConstruct, ConstraintDomain, ViewMappingFunction, ExposureContext, VmfPort, and CdPort. 

View mapping function (VMF) lightweight view:

Bottom level of view mapping: Multiple Nodal view mapping,  each is 1-in 1-out (so multiplicity = 2); normalization, simple transformation, adjacency discovery of neighboring nodal view, trivial tasks

Multiple VPs (view mapping port): *

Simplified Spec model (Not discussed due to running out of time)

Plan of next calls

23 March

  • Controller model
  • Simplified Spec model
    • To clarify "Simplified" means more to Uniform approach and system/component pattern. That can be applyied, e.g., to TAPI connection rules, etc.


  • IETF I-D generation: Nigel will provide a pre-tool format example
