DISCUSS:
----------------------------------------------------------------------

It is unclear to me what the purpose of the pause and resume is here?

Is it to enable the router to build the queue rather than the modem if there is
a queue buildup in the modem? If that is the case, then pause and resume will
be done frequently and on short time scales due to variability of the link. And
then the router resumes transmission to the modem when the buffer has been
reduced? As this is enabled to be done on a queue level what how does one
ensure the per hop behavior that is intended based on the DSCP with this split.
Because you will get an interaction between the two queue that are in series
for the same link which makes ensuring the PHB difficult.

I hope for a timely clarification to determine if this is a discuss or not and
make it more actionable.
