Transmit Pseudo-Random Binary Sequence
A one in this bit position enables transmission of a pseudo-random
binary sequence to the remote end. Depending on bit LLBP the PRBS
is generated according to 2
H
Transmit clock is generated from the clock supplied by MCLK
which is synchronized to the extracted receive route clock. In
this configuration the transmit elastic buffer has to be enabled.
Refer to register FMR5.XTM. For correct operation of loop
timed the remote loop (bit LIM1.RL = 0) must be inactive and bit
CMR1.DXSS must be cleared.
Normal operation
The LOS alarm is cleared if the predefined pulse-density
(register PCR) is detected during the time interval which is
defined by register PCD.
Additionally to the recovery condition described above a LOS
alarm is only cleared if the pulse-density is fulfilled and no more
than 15 contiguous zeros are detected during the recovery
interval (according to GR-499-CORE).
Pseudo-random binary sequence (PRBS) monitor is disabled.
PRBS is enabled. Setting this bit enables incrementing the bit
error counter BEC with each detected PRBS bit error. With any
change of state of the PRBS internal synchronization status an
interrupt ISR3.LLBSC is generated. The current status of the
PRBS synchronizer is indicated by bit FRS1.LLBAD.
