Address 00C5h
Local BER Receive Length Register (LRXBLR) defines how many channels the BER sequence will be received
during each frame. The LRXBLR register is configured as follows:
13.10.3
Address 00C6h
Local BER Start Receive Register defines the Input Stream and Start Channel and the stream in which the BER
sequence shall be received. The LBSRR register is configured as follows:
13.10.4

Local Bit Error Rate Count
The binary value of the bits define the Local Bit Error count.
Reserved.
Local Receive BER Length Bits
The binary value of these bits define the number of channels in addition
to the Start Channel allocated for the BER receiver. (i.e., Total Channels =
Start Channel + LRXBL value)
Reserved.
Local BER Receive Stream Address Bits
The binary value of these bits refers to the local input stream to receive
the BER data.
Local BER Receive Channel Address Bits
The binary value of these bits refers to the local input channel in which
the BER data starts to be compared.
