2.3.5
The upstream D-channel is arbitrated between the S-bus and external HDLC controllers
via the TIC bus (S/G, BAC, TBA bits) according to the IOM -2 Reference Guide
Further to the implementation in the INTC-Q it is possible, to set the priority (8 or 10) of
all HDLC-controllers connected to IOM -2, which is particularly useful for use of the Q-
SMINT I together with the UTAH.
