Alarms/Errors Overview
Errors
B1 (BIP-8, Bit-Interleave Parity - 8 bits)
RX: Indicates a Section parity error by performing a routine even-parity
check over all Section bits of the previous frame of a composite signal
(located in the first STS-1 of an STS-n signal).
B2 (BIP-1536, Bit-Interleave Parity - 1536 bits)
RX: Indicates a Line parity error by performing a routine even-parity
check over all Line bits of the LOH and STS-1 frame capacity of the
previous frame of a composite signal (located in every STS-1 of an
STS-n signal).
B3 (BIP-8, Bit-Interleave Parity - 8 bits)
RX: Indicates a Path parity error by performing a routine even-parity
check over all Path bits of the previous SPE excluding the LOH and
SOH.
REI-L (Remote Error Indicator - Line)
RX: Bits 5 through 8 of the M0 byte contain one pattern from the
following binary range: “0001" through “1000" (1 to 8) (located in the
first STS-1 of an STS-n signal).
REI-P (Remote Error Indicator - Path)
RX: Bits 1 through 4 of the G1 byte contain one pattern from the
following binary range: “0001" through “1000" (1 to 8) (located in every
STS-1 of an STS-n signal).
