Transmit Pseudo Random Bit Sequence
A one in this bit position enables transmitting of a pseudo random bit
sequence to the remote end. Depending on pit LLBP the PRBS is
generated according to 2
restriction ( ITU-T O. 151).
H
(register PCR) is detected during the time interval which is
defined by register PCD.
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 TR-NWT 499).
no more than 99 contiguous zeros are detected during the
recovery interval. (according to TR-NWT 820).
Pseudo random bit sequence (PRBS) monitor is disabled.
PRBS monitor is enabled. Setting this bit enables incrementing
the CEC2 error counter with each detected PRBS bit error. With
any change of state of the PRBS internal synchronization
status an interrupt ISR1.LLBSC is generated. The current
status of the PRBS synchronizer is indicated by bit
RSP.LLBAD. The expected PRBS sequence has to be selected
by bit LCR1.LLBP.
The PRBS status signal is output on pin RFSP, if
FMR3.CFRZ=0 and LCR1.EPRM=1. It is set high, if the PRBS
monitor is in synchronous state.
