The IETF PCN Working Group has continued its work investigating pre-
congestion and admission control mechanisms.  This work has
progressed under the current charter, but has not yet considered
related legacy PSTN interactions or the need for ubiquitous
connectivity between users on dissimilar networks.  The PCN charter
could be improved by a strong positive statement to the effect
committing to future work addressing legacy networks.

In that light, please consider the questions below which include
differential PCN treatment based on traffic types, security, and PSTN
interoperability concerns.  It seems helpful to have a touchstone of
some concerns relative to the PSTN network and IP network Gateway in
order to confirm that they will be addressed in future work.  This
attempt is motivated by a desire to avoid the accidental omission of
a topic that may be hard to "retrofit" in later.
