SyncE Wander Tolerance using Tones: Option 1 and Enhanced (Tolerance Level 2)
(Note that for Enhanced SyncE clocks (specified in G.8262.1), there are two tolerance levels. Level 2 is the same as the tolerance for standards SyncE clocks (specified in G.8262).
Parameters used:
- Measured at each corner point in G.8262/Figure 7
- At least one point per decade
