Monitoring Data

simultaneously. For monitoring on DU and/or DD the channel registers with even
numbers (CDA10, CDA20) are assigned to time slots with even numbers TS(2n) and the
channel registers with odd numbers (CDA11, CDA21) are assigned to time slots with odd
numbers TS(2n+1). The user has to take care of this restriction by programming the
appropriate time slots.
However, this rule is only valid if two blocks (e.g. transceiver and HDLC controller) are
programmed to these timeslots and are communicating via IOM-2. If only one block is
programmed to this timeslot, the timeslots for CDAx0 and CDAx1 can programmed
completely independently.

Monitoring TIC Bus (TE mode)
Monitoring the TIC bus (TS11) is handled as a special case. The TIC bus can be
monitored with the registers CDAx0 by setting the EN_TBM (Enable TIC Bus Monitoring)
bit in the control registers CRx. In this special case the TSDPx0 must be set to 08
monitoring from DU or 88
monitor the TIC bus (TS11) and the odd numbered D-channel (TS3) simultaneously on
DU and DD.
