Alarms
BDI (Backward Defect Indication)
RX: The BDI bit in the TCM overhead field Byte 3, bit 5 is “1” for at least
5 consecutive frames.
TX: Generates a "1" in the BDI bit of the TCM overhead field (byte 3,
bit 5) continuously.
BIAE (Backward Incoming Alignment Error)
RX: The BEI/BIAE bits in the TCM overhead field Byte 3, bits 1 to 4 are
“1011” for at least 3 consecutive frames.
TX: Generates "1011" in the BEI/BIAE bits of the TCM overhead (byte 3,
bits 1 to 4) continuously.
IAE (Incoming Alignment Error)
RX: The STAT information in the TCM is “010” for at least 3 consecutive
frames.
TX: Generates "1" in the IAE bit of the TCM overhead (byte 3, bit 6)
continuously.
LTC (Loss of Tandem Connection)
RX: The STAT information in the TCM Byte 3, bits 6, 7, and 8 are “000”
for at least 3 consecutive frames.
TX: Generates "000" in the STAT field of TCM overhead (byte 3, bits
6 to 8) continuously.
TIM (Trace Identification Mismatch)
RX: The SAPI and/or DAPI do not math the expected SAPI and/or DAPI.
This alarm is only available when the Enable TIM SAPI and/or DAPI
check boxes are selected from PT on page 147.
