All:
Is this worth bringing up at the next ATM meeting?
If there is need to revert back to including Usage Out
for Tx_Jitter and Tx_DCD in Version 6.0 we could do it
with a quick correction BIRD. Usage Out is currently supported
in Version 5.1, so there is no known damage. We could
consider other Jitter and Noise Parameters at that time.
We are editing this area, so we want to get this right
for the next release.
Bob

Walter can answer the direct question, but for background Tx_Jitter
and Tx_DCD were changed to Info only in BIRD 123.5
(http://www.eda.org/ibis/birds/bird123.5.docx).
