CiscoNetsyncQualityLevel

• Base type Enumeration

Clock source QL (quality level) is defined in ITU-T G.781 section 5.4 to reflect the synchronization quality within a network Option, i.e. I, II, and III. The following clock source quality levels are defined for the synchronization process of Option I: QL-PRC Primary reference clock QL-SSU-A Type I or V slave clock defined in ITU-T G.811 QL-SSU-B Type VI slave clock defined in ITU-T G.812 QL-SEC Synchronous equipment clock QL-DNU Do not use for synchronization QL-INVx Unallocated SSM value, where x represent the value of SSM received QL-FAILED Signal failure state QL-UNC Unconnected to an input QL-NSUPP Not supporting the SSM processing The following clock source quality levels are defined for the synchronization process of Option II: QL-PRS PRS traceable QL-STU Synchronized; traceability unknown QL-ST2 Stratum 2 QL-TNC Transit node clock QL-ST3E Stratum 3E QL-ST3 Stratum 3 QL-SMC SONET clock self timed QL-ST4 Stratum 4 freerun QL-PROV Provisionable by the network operator QL-DUS Do not use for synchronization QL-INVx Unallocated SSM value, where x represent the value of SSM received QL-FAILED Signal failure state QL-UNC Unconnected to an input QL-NSUPP Not supporting the SSM processing The following clock source quality levels are defined for the synchronization process of Option III: QL-UNK Unknown clock source QL-SEC Synchronous equipment clock QL-INVx Unallocated SSM value, where x represent the value of SSM received QL-FAILED Signal failure state QL-UNC Unconnected to an input QL-NSUPP Not supporting the SSM processing
