61200659L1-1 MX2800 STS-1 User Manual 4-3
LOMF (Loss of Multiframe)
The controller card detects loss of H4 multiframe
from the network.
AIS-L (Line Alarm Indication Signal)
The controller card is receiving a line alarm
indication signal. The Section Terminating
Equipment generates AIS-L after detecting LOS
or LOF.
AIS-P (Path Alarm Indication Signal)
The controller card is receiving a path alarm
indication signal. AIS-P is defined as all ones in
bytes H1, H2, and H3 as well as all ones in the
entire STS synchronous payload envelope.
RFI-L (Line Remote Failure Indication)
The controller card is receiving a line remote
failure indication. RFI-L is declared when the
incoming line remote defect indication (RDI-L,
“110” pattern in bits 6, 7, and 8 of the K2 line
overhead byte) lasts for 2.5 +/- 0.5 seconds.
RFI-P (Path Remote Failure Indication)
The controller card is receivinga path remote
failure indication. RFI-P is declared when the
incoming path remote defect indication (RDI-P, “1”
in bit 5 of the G1 path overhead byte for
contiguous frames) lasts for 2.5 +/- 0.5 seconds.
SLM-P (Path Signal Lavel Mismatch)
The controller card is detecting a signal label
mismatch. A received signal label is mismatched
if it does not equal the locally provisioned value or
the value “equipped non-specific”.
UEQ-P (Path Unequipped)
The controller card detects that the path is
unequipped. The path is unequipped if it is not
provisioned. Byte C2 of the STS path overhead is
set to zero.
