C/I:
two bits for the 16 kbit/s D-channel
The four command/indication (C/I) bits are used for control of the U
transceiver (activation/deactivation and additional control
functions).
MR, MX:
two bits MR and MX for the handshake in the Monitor Channel 0

C/I1 to C/I6 are used for control of a transceiver or an other device in IOM®-2
channel 1 (activation/deactivation and additional control functions).
MR, MX:
two bits MR and MX for handshake in the Monitor Channel 1

BAC-bit
(Bus ACcessed). When the TIC bus is occupied the BAC-bit is low.
