Well. Seems that I already found the answer in another post below.

    Hard CBR: no bit-reservoir, every frame (21.5-43 ms) has the same bit consumption (e.g. -hard-cbr in Opus)
    Soft CBR: small bit-reservoir, for example one with the size given in the MPEG standard (e.g. Fraunhofer CBR)
    ABR: large bit-reservoir, maybe up to a few seconds. Entirely up to the developer (e.g. ABR in Nero's encoder?)
    CVBR: very large bit-reservoir, maybe up to a minute. Entirely up to the developer (e.g. CVBR in Apple's encoder?)
    TVBR: maximum bit-reservoir, every frame and channel may use between ~10 and 6144 bits (e.g. Apple's or Fraunhofer's VBR)

Sorry for not checking before.
