No.  Ala Q.703 it sends LS PR when it recovers and only then both
sides exchange LSR.  Neither side resynchronizes until the link
becomes unblocks which requires no processor outage (local or remote).

Each side resynchronizes independently per Q.703.  The sequence when the
last terminal recovers is the same as though only one processor was out.
