The FALC
by registers RTR1-4 and TTR1-4, to the RFIFO and XFIFO, respectively. Any
combinations of time slots can be programmed for the receive and transmit directions. If
CCR1.EITS = 1 the selected time slots (RTR1-4) are stored in the RFIFO of the signaling
controller and the XFIFO contents is inserted into the transmit path as controlled by
registers TTR1-4.

In receive direction, transparency for ternary or dual/single rail unipolar data is always
achieved if the receiver is in the synchronous state and bit FMR5.RTF is set. All bits in
the F-bit position of the incoming multiframe are forwarded to RDO and inserted in the
FS/DL time-slot or in the F-bit position.
In asynchronous state the received data may be transparently switched through if bit
FMR2.DAIS is set.
For the receive path bit FMR5.RTF has the same function as bit FMR4.TM.
