Description
This parameter indicates the number of seconds with
one or more coding violations or one or more incoming
defects (SAIS-P, LOP, UNEQ-P) at the Path Layer.
This parameter indicates the number of seconds with x
or more coding violations at the Path Layer, or a second
during which at least one or more incoming defects at
the Path Layer has occurred (Values of x vary dependent
upon the line rate and the Bit Error Rate).
This parameter indicates the time in seconds that the
Path Layer has been unavailable for data delivery
Condition Description
This condition indicates the unit has lost the network
receive signal.
This condition indicates the unit detects a framing loss
from the network.
This condition indicates the unit is unable to detect a
valid pointer in the receive signal.
This condition indicates the unit detects loss of H4 mul-
tiframe from the network.
This condition indicates the unit is receiving a line
alarm indication signal (the section terminating equip-
ment generates AIS-L after detecting LOS or LOF).
This condition indicates the unit is receiving a line
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).
This condition indicates the unit is receiving a line
remote failure indication (RFI-L is declared when the
incoming line remote defect indication [RDI-L, "110" pat-
tern in bits 6, 7, and 8 of the K2 line overhead byte] lasts
for 2.5 ±0.5 seconds.
