Alarms/Errors Overview
ODUCn
Note: For OPUCn alarms/errors see page 439.
Alarms
AIS (Alarm Indication Signal)
RX: The STAT information in the PM byte 3, bits 6 to 8 of ODUC #1 is
“111” for at least 15 consecutive frames.
TX: Generates an all "1"s pattern in the entire ODUC signal, excluding
the frame alignment overhead (FA OH), and OTUC overhead (OTUC
OH).
LCK (Lock)
RX: STAT information in the PM byte 3, bits 6 to 8 of ODUC #1 is “101”
for at least 15 consecutive frames.
TX: Generates a repeating "01010101" pattern in the entire ODUC
signal, excluding the frame alignment overhead (FA OH) and OTUC
overhead (OTUC OH).
BDI (Backward Defect indication)
RX: The BDI bit in the PM overhead field (byte 3, bit 5) of ODUC #1 is
“1” for at least 15 consecutive frames.
TX: Generates a “1” in the BDI (byte 3, bit 5) of the PM overhead field of
the ODUC #1 continuously.
TIM (Trace Identification Mismatch)
RX: The received SAPI and/or DAPI do not math the expected SAPI
and/or DAPI. This alarm is only available when the SAPI ODU-TIM
and/or DAPI ODU-TIM check boxes are selected from PT / Global PT on
page 379.
