THREE CHANNEL E3/DS3/STS-1 LINE
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 "Continuous" pattern of Pointer Adjustments, must not exceed 1.0UI-
pp. The spacing between individual pointer adjustments (within this scenario) can range from 7.5ms to 10s.

Continuous Add
Figure 56 presents an illustration of the "Continuous Add Pattern" Pointer Adjustment Scenario per Telcordia
GR-253-CORE.
Telcordia GR-253-CORE defines an "Continuous Add" Pointer Adjustment, as the "Continuous" Pointer
Adjustment pattern, with an additional pointer adjustment inserted, as shown above in Figure 56.
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 "Continuous Add" pattern of Pointer Adjustments, must not exceed
1.3UI-pp.

Continuous Cancel
Figure 57 presents an illustration of the "Continuous Cancel Pattern" Pointer Adjustment Scenario per
Telcordia GR-253-CORE.
