1.7.181 OPEN-SLOT

The Out of Use Transport Failure alarm is a VCAT member alarm. (VCAT member circuits are
independent circuits that are concatenated from different time slots into a higher-rate signal.) This
condition is raised when a member circuit in a VCAT is unused. It occurs in conjunction with the
"VCG-DEG" alarm on page

1.7.182 PDI-P

A PDI-P is a set of application-specific codes indicating a signal label mismatch failure (SLMF) in the
ONS 15310-CL or ONS 15310-MA STS path overhead. The condition indicates to downstream
equipment that a defect is present in one or more of the directly mapped payloads contained in that STS
synchronous payload envelope (SPE). For example, the mismatch could occur in the overhead to the path
selector in a downstream node configured as part of a path protection. The PDI-P codes appear in the
STS Signal Label (C2 byte).
An SLMF often occurs when the payload does not match what the signal label is reporting. The
condition on page 1-19
with the AIS, clearing PDI-P clears the AIS. PDI-P can also occur during an upgrade, but usually clears
itself and is not a valid condition.
