Reserved. In normal functional mode, these bits MUST be set to zero.
Local BER Receive Stream Address Bits: The binary value of these bits refers to
the local input stream which receives 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.
Reserved. In normal functional mode, these bits MUST be set to zero.
Local BER Length Bits: The binary value of these bits refers to the number of chan-
nels, the BER data will last. The maximum number of local BER channels is 127.
Local Bit Error Rate Count: The binary value of these bits refers to the local bit error
count.
