We consider a two-phase queueing system with a finite number of places in the buffer between phases and unreliable servers. The servers at phases function synchronically. The ergodicity condition is obtained and functioning of the system under heavy traffic assumptions is studied.

Key words: multiphase queueing systems, ergodicity condition, heavy traffic assumptions.
