With the configuration settings shown above the Q-SMINT I in intelligent NT
applications provides for equal access to the D-channel for terminals connected to the
S-interface and for D-channel sources on IOM -2.

the number of ’1’ on the IOM -2 D-channel and BAC corresponds to the BAC-bit on
IOM -2. The number n depends on configuration settings (selected priority 8 or 10) and
the condition of the previous transmission, i.e. if an abort was seen (n = 8 or 10,
respectively) or if the last transmission was successful (n = 9 or 11, respectively).
