3.7.5.1
The TIC bus is imlemented to organize the access to the layer-1 functions provided in
the SBCX-X (C/I-channel) and to the D-channel from up to 7 external communication
controllers
Note: The TIC Bus can be used in TE/iNT mode only. In other modes it has to be
To this effect the outputs of the D-channel controllers (e.g. ICC - ISDN Communication
Controller PEB 2070) are wired-or (negative logic, i.e. a “0” wins) and connected to pin
DU. The inputs of the ICCs are connected to pin DD. External pull-up resistors on DU/
DD are required. The arbitration mechanism must be activated by setting
TR_MODE2.DIM2-0=00x.
Figure 60
The arbitration mechanism is implemented in the last octet in IOM-2 channel 2 of the
IOM-2 interface
by software via a µP access to the C/I channel or by one of the D-channel controllers
(ICC). A software access request to the bus is effected by setting the BAC bit (CIX0
register) to ’1’.

switched off in order not to disturb the layer-1 control. This is done by
setting bit DIM 1 in register Mode D and bit 4 in register IOM_CR. For more
details please refer to the application note “Reconfigurable PBX”.
