Test Results
344 FTB-700G/800 Series
Alarms/Errors
ERDI-PCD (Enhanced RDI - Path Connectivity Defect)
RX: Bits 5, 6 and 7 of the G1 byte contain the “110” pattern in five to ten
consecutive frames.
TX: Generates a “110” pattern for bits 5, 6 and 7 of the G1 byte.
ERDI-PPD (Enhanced RDI - Path Payload Defect)
RX: Bits 5, 6 and 7 of the G1 byte contain the “010” pattern in five to ten
consecutive frames.
TX: Generates a “010” pattern for bits 5, 6 and 7 of the G1 byte.
PLM-P/UNEQ-P (Payload Label Mismatch - Path / Unequipped - Path)
check box when selected (cleared by default) enables the Signal Label
Mismatch for the expected message defined as well as UNEQ-P
monitoring.
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.
