Receive FS/DL Bits on RDO
Each data bit is repeated for two frames. The reception of a new FS/DL bit is indicated by the
Receive Data Change Flag (normal operation: RDCF toggles; transparent mode enabled via bit
GCR.TM: RDCF is set, if the FS/DL bit-slot contains valid DL information). For further support in
locating optionally defined subchannels, the Receive Multiframe Flag and the Transmit Multiframe
Flag are provided for marking the beginning of the multiframe. In addition, the signals RMFB and
XMFB may be used for that purpose.

Transmit FS/DL Bits on XDI
The FS/DL bit of every second frame is inserted into the transmit FS/DL-bit location of the assigned
outgoing 193-bit frame.
