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 standard SyncE clocks as specified in G.8262.
Parameters used:
- Measured at each corner point in G.8262/Figure 7
- At least one point per decade
