Brian,

Thanks. It is much clearer now - the only necessary condition for 
resumption of traffic is that processor outage ceases.

So please change the last paragraph of section 4.2.4 to:

"If the processor outage condition ceases, M2PA shall resume receiving
and transmitting messages."

Also, the draft would be much easier to follow if this sentence was moved 
to section 4.1.4.

Barry.Nagelberg,

If MTP3 wants to flush buffers before a processor outage condition
recovers, it does so.  If it does not, MTP2 (and M2PA) is free to
transmit buffered messsages when the remote processsor outage
condition recovers or to deliver received buffered messages when
the local processor outage condition recovers.

Thus M2PA can resume transmitting messages when it receives
FLUSH_BUFFERS/CONTINUE _and_ it receives LS processor outage ended,
and can also resume transmitting messages when it just receives
LS processor outage ended.
