2.048 MHz Receive Signaling Highway
Time-Slot Assigner
The QuadFALC offers the flexibility to connect data during certain time-slots, as defined
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) will be stored in the RFIFO of the
signaling controller and the XFIFO contents will be inserted into the transmit path as
controlled by registers TTR1-4.
