Receive Line Attenuation Indicators. Convert this binary output to a decimal number
and multiply by 2.9 dB to determine the approximate cable attenuation as seen by the
receiver.
For example, if LATN7:4 = 1010
attenuated by approximately 29 dB (2.9 dB x 10) of cable. This approximation
assumes that a 3 V pulse was transmitted.
1 = Enable detection of HDB3 code violations at the BPV pin along with bipolar
violations and Zero Substitution Violations (if enabled).
0 = Disable detection of HDB3 code violations.
1 = Enable detection of HDB3 Zero Substitution Violations (four consecutive zeros).
Note that Zero Substitution Violations are reported at the BPV pin.
0 = Disable detection of HDB3 Zero Substitution Violations.
1 = Set LOS detection threshold to 2048 consecutive zeros.
0 = Set LOS detection threshold to 32 consecutive zeros (for E1 operation) or to 175
consecutive zeros (for T1 operation).
