New Discussion:

There was no interconnect task group meeting to report on

BIRD 123:
- Arpad: I sent am email on this topic
  - Arpad showed text from the email
- Walter: I disagree because someone may know what their DCD is
  - They may want a separate Rj
  - DCD has a different spectrum from Rj
- Fangyi: I agree with Walter
- Walter showed BIRD 123.4 draft 3
  - A sentence has been added to clarify Rx_Clock_Recovery_Dj
- David: The user should be able to put all jitter in a single parameter if he chooses
- Walter added a phrase to incorporate that possibility.
- Radek: This does not add clarity
- Fangyi: Can we say "one or more"?
- Arpad: Why do we need this?
- David: It will be unclear what to do with this parameter
- Walter made further edits to the BIRD, moving some language to Other Notes
- Bob: This could be in the notes section.
- Fangyi: Model makers will have questions if their jitter is combined differently
  - The main rule is that we must not have any double counting
- David: Three small sentences might be better than one long one.
- Fangyi: What goes in may depend on whether clock times are available
- David: I thought these separate parameters were all to be used for clock times
- Walter continued editing along these lines
- Fangyi: What about the non-Clock_Recovery jitters?
- Ambrish: All three can be defined?
- Walter: Yes, but they don't have to be
- David: I sometimes set two of them to zero
- Fangyi: The "Total ... is the sum" sentence is not clear enough.
- More brainstorming on how to describe clock and non-clock jitter summation
- Walter changed the format of jitter equations for clarity
- Walter: I will make more edits and post this as draft 4
- Fangyi: What if Rx_Clock_PDF is specified together with this?
- Bob: What does the spec say?
- Walter: I will check on that

AR: Walter post BIRD 123.4 draft 4 with updates

BIRD 121:
- Arpad: I found only one spelling mistake.
- Walter showed BIRD 121.2 draft 4
  - This becomes draft 5 now
- Arpad: We will be able to vote on this next week

AR: Walter post BIRD 121.2 draft 5 with updates

BIRD 150:
- Walter showed BIRD 150.1 draft 2
- Walter: I added an underscore to Column_Types
- Arpad: Has this been reviewed to check for translation problems?
- Mike: Side by side review seems like an individual task
- Ambrish: Is there a list of editorial changes that will go into 5.2?
- Michael M: We are open for suggestions
- Walter: We could have an errata page to accumulate typographical errors
- Ambrish: The Value Format change changes the meaning
- Bob: Is Dependency_Table a reserved word?
- Walter: It is a new Usage
- Bob: Do the parameters have to be defined?
- Walter: Yes it requires that
- Arpad: Do we need a new Usage for parameters that only control the table?
  - We will review this again
