  T CrB is a symbiotic recurrent nova that exhibits quiescent and active phases
between its classical nova eruptions. The statistical properties of these
active phases have been poorly studied thus far. Because of that their nature
remained unknown. Here we study statistical properties of the active phases and
show that they are consistent with outburst and superoutbursts observed in SU
UMa type dwarf novae. The recurrence time of these outbursts is consistent with
theoretical predictions for similar systems. Moreover, the visual and X-ray
evolution of the last active phase is consistent with a superoutburst. This
suggests that T CrB is a dwarf nova with an extremely long orbital period,
closely related to SU UMa dwarf novae. The similarities between the last
superoutburst and the reported activity preceding the 1946 nova eruption may
suggest that next classical nova eruption in T CrB could be indeed soon
expected.
