Resolved Software Caveats for Release 3.3
Figure 1
Provision a circuit over the UPSR with a DS-1 drop at each end. Clear all fifteen-minute counts on
near-end and far-end bins. From the variable optical attenuator, increase the attenuation ~20 db. The
OC-48 trunk card starts to see signal degrade (SD) on its line. The near-end DS-1 port on the ONS 15327
starts to accumulate CV-V and ES-V. The far-end DS-1 should also show PM counts (i.e. CV-V, ES-V,
SES-V, UAS-V), but does not. This issue is resolved in Release 3.3.
DDTS # CSCds66639
When the PM counters are zeroed, the entries for CV-V, ES-V, SES, and UAS-V are not colored yellow
to mark them as "invalid." Provision VT circuits. In CTC, browse to the Performance Monitoring tab for
one of the DS-1 facilities involved in the VT circuits. Attempt to zero the PM counters. The entries for
the zeroed counters should turn yellow to indicate that they are invalid assessments of the current time
period, but they do not change color. After zeroing the performance counters, all counters become valid
at the same time. To determine if an affected counter is valid, note whether all other counters in the same
time block are valid. This issue is resolved in Release 3.3.
DDTS # CSCds77660
The ONS 15327 might report TCAs for VT-level unavailable seconds (UAS-V), errored seconds (ES-V),
and coding violations (CV-V) when the PM counts are not changing. These TCAs have been seen on
DS-1 Ports 3 and 5. From the CTC Circuits tab, use the Create button to build VT circuits from several
DS-1 ports. Monitor the Alarms tab for TCAs. This issue is resolved in Release 3.3.
