D-channel access control is defined to guarantee all connected TEs and HDLC
controllers a fair chance to transmit data in the D-channel. Collisions are possible
• on the IOM-2 interface if there is more than one HDLC controller connected or
• on the S-interface when there is more than one terminal connected in a point to
Both arbitration mechanisms are implemented in the ISAC-SX and will be described in
the following two chapters.
3.7.5.1
The TIC bus is imlemented to organize the access to the layer-1 functions provided in
the ISAC-SX (C/I-channel) and to the D-channel from up to 7 external communication
controllers (see
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
MODED.DIM2-0=00x.

switched off in order not to disturb the layer-1 control and the HDLC
controller. 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
