Query: New Look at Finite Single Server Queue with Poisson Input and
  Semi-Markov Service Times   The mathematics of the finite single server queue with Poisson input and
semi-Markov service times($M/SM/1/b$) is similar to that used for $BMAP/G/1/b$
systems. This observation results in new analytical formulas for a queue size
in the $M/SM/1/b$ system. Both stationary and the transient solutions are
considered
