E3/DS3/STS-1 LINE INTERFACE UNIT WITH SONET DESYNCHRONIZER
REV. 1.0.2

Telcordia GR-253-CORE defines an "87-3 Cancel" Pointer Adjustment, as the "87-3 Continuous" Pointer
Adjustment pattern, with an additional pointer adjustment cancelled (or not executed), as shown above in
Figure 53.
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 Cancel" pattern of Pointer Adjustments, must not exceed 1.3UI-
pp.

Continuous Pattern
Figure 54 presents an illustration of the "Continuous" Pointer Adjustment Scenario per Telcordia GR-253-
CORE.
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 55 presents an illustration of the "Continuous Add Pattern" Pointer Adjustment Scenario per Telcordia
GR-253-CORE.
