In the present work we have computed
the ON- and OFF-state generations on high resolution
grid for microquasar CYG X-1. The results shows that
in disk the ON-state time intervals are equal to OFF-
state time intervals and these intervals are equal to 2
precession periods. The OFF-states are corresponding
to low disk mass accretion rate and ON-states are cor-
responding to high disk mass accretion rate. The tran-
sition between both states is suddenly, on very short
time scale order of 20 minute of orbital time.
