The IBUS-interface D- and B-channels are used to convey the 16-kbit/s signalling
channel and the two 64-kbit/s user channels in both directions. However, the transceiver
only transfers the data transparently in the activated state (incl. analog loop activated)
while the data are set to ‘1’ in any non activated state.

The layer-1 activation/ deactivation can be controlled by an internal statemachine via the
IBUS C/I0 channel or by software via the UBUS interface directly. In the default state the
internal layer-1 statemachine of the INCA-D is used.
By setting the L1SW bit in the TR_CONF0 register the internal statemachine can be
disabled and the layer-1 transmit commands, which are normally generated by the
internal statemachine can be written directly into the TR_CMD register or the received
status read out from the TR_STA register, respectively. The INCA-D layer-1 control flow
is shown in figure 18-3.
Figure 18-3 Layer-1 Control
In the following sections the layer-1 control by the INCA-D statemachine will be
described.
The layer-1 functions are controlled by commands issued via the C/I channel 0 of the
IBUS interface to the layer-1 to trigger certain procedures, such as activation/
deactivation, switching of test loops and transmission of special pulse patterns.
