A test plan for SyncE jitter and wander peformance to G.8261 and G.8262. This paper details the test procedures specified in the ITU-T G.8261 and G.8262 standards for Sync-E Jitter and Wander performance.
A ready-made test plan for Telecom Boundary Clocks to ITU-T G.8273.2 standard. This paper details the tests available to comply with G.8273.2. Calnex makes recommendations on what tests may be appropriate.
The accuracy of Telecom Time Slave Clocks (T-TSCs) is essential to the successful roll-out of LTE-A and TDD-LTE. To meet the new G.8273.2 compliance limits, T-TSCs must meet a very stringent constant Time-Error (cTE) limit of 20 or 50 nanoseconds.
The Calnex Analysis Tool (CAT) provides a range of pre-defined ITU-T masks to verify that the performance of network devices meets the relevant standards. The CAT also lets you define your own masks; this application note shows you how.
The issues that need to be considered and some tips on how to ensure the uncertainty due to cable delay is minimised when performing high accuracy Time Error measurements. Down at the ns level it is important to consider the cabling in all test set ups.
