Error Analysis
³
BIP-2 (Bit-Interleave Parity - 2 bits): The BIP-2 error indicates a Low
Order Path parity error by performing a routine even-parity check over
all bytes of the previous VC frame.
³
LP-REI (Low Order Path Remote Error Indicator): The LP-REI error is
declared when bit 3 of the V5 byte is set to “1”.
Note: Refer to Alarm/Error Measurements on page 47 for H/C LEDs, Seconds,
