87-3 Pattern
Figure 51 presents an illustration of the "87-3 Continuous Pattern" Pointer Adjustment Scenario per Telcordia
GR-253-CORE.
Telcordia GR-253-CORE defines an "87-3 Continuous" Pointer Adjustment pattern, as a repeating sequence of
90 pointer adjustment events. Within this 90 pointer adjustment event, 87 pointer adjustments are actually
executed. The remaining 3 pointer adjustments are never executed. The spacing between individual pointer
adjustment events (within this scenario) can range from 7.5ms to 10seconds.
Telcordia GR-253-CORE mandates that the Intrinsic Jitter, within the DS3 signal that is de-mapped from a
SONET signal, which is experiencing the "87-3 Continuous" pattern of Pointer Adjustments, must not exceed
1.0UI-pp.
