Performance monitoring
suppressed. This means that the data would not be transferred to the next available, or
recent bin. The default value for the maximum number of consecutive suppressed
intervals is zero, but can be provisioned per termination point for each accumulation
period.
UAP log
The UAP log is an additional storage method. This log is a register that holds data of
the six most recent periods of UAT. The UAP log timestamps each period of
unavailability with a UAT begin and UAT end time. A period of UAT starts at the first
second of a first UAS occurrence (see UAS, in SDH Measurement Parameters). UAT is
implicitly provisioned as soon as a unidirectional termination point is configured. An
operator can view the UAP log, maintain log of last month and use the NE data to
synchronize the ITM CIT data.
If during an UAT period the NE clock is reset, the current UAT period shall end with a
timestamp of the old time and a new UAT period shall be started with a timestamp of
the new time.
UAP counter
A UAP counter, called BiDirUAPcount, tracks the number of unavailable periods. This
counter can be viewed and reset by the operator.
Reset of PM counters
The ITM CIT offers the possibility to reset the parameters counter for uni and/or
bidirectional monitoring in order to assist with maintenance activities. When the
management system sends this request to the NE, the bin content is reset for the
current 15 minutes bins and the content of the current 24 hours bins associated with a
termination point.
Resetting the counters has the following consequences:
• Elapsed time is reset to zero;
• PM counters value (BBE, ES, SES, UAS, UAP) are reset to zero;
• UAPlog counter is NOT affected;
• Suspect indication is set.
Data Recovery Following Loss of Association
If the association between ITM-CIT and the NE fails, the ITM-CIT regains information
about the lost time by reading the NE bins for the relevant interval. If the association
fails for a longer period of time the NE may not be able to store sufficient information
for a full recovery.
