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.
