These results correspond to different values of the $C_{10}$ parameter. As it is discussed in more detail below (see Sec. IV A subsection 3 and 4), a CIR process belongs to the transmission minima which occur in the interval of energies among the open channels. Specifically, in Fig. \[fig:transmission\_trend\_s\] (a) we observe that for $\epsilon<1$, ie between the thresholds of the ground and first excited transverse state, the transmission minima for varying values of the scattering lengths leads to a transmission blockade. For $1<\epsilon<2$ and higher energies the minimal value of the transmission is nonzero and increases with increasing channel the energy belongs to. The transmission exhibits a repeating pattern shifted to higher values. The locations of the minima with varying scattering length form thus a “topos“ which in Fig. \[fig:transmission\_trend\_s\] is denoted by the black dot-dashed line: This is the [*confinement-induced*]{} (CI) unitarity bound and represents a universal feature. We should note however that the specific functional form of the CI unitarity bound depends on the particular $\ell$-wave character of the collisions. Furthermore, in Fig. \[fig:transmission\_trend\_s\](a) we observe that a CIR occurs for positive scattering length at $\Delta\epsilon < 0.69$, while CIRs of negative values of $\bar{a}_0$ emerge for
