THREE CHANNEL E3/DS3/STS-1 LINE INTERFACE UNIT WITH SONET DESYNCRONIZER
REV. 1.0.4
NOTE: All of these intrinsic jitter measurements are to be performed using a band-pass filter of 10Hz to 400kHz.
Each of the scenarios presented in Table 31, are briefly described below.
10.5.1
DS3 De-Mapping Jitter
DS3 De-Mapping Jitter is the amount of Intrinsic Jitter that will be measured within the "Line" or "Facility-side"
DS3 signal, (after it has been de-mapped from a SONET signal) without the occurrence of "Pointer
Adjustments" within the SONET signal.
Telcordia GR-253-CORE requires that the "DS3 De-Mapping" Jitter be less than 0.4UI-pp, when measured
over all possible combinations of DS3 and STS-1 frequency offsets.
10.5.2
Single Pointer Adjustment
Telcordia GR-253-CORE states that if each pointer adjustment (within a continuous stream of pointer
adjustments) is separated from each other by a period of 30 seconds, or more; then they are sufficiently
isolated to be considered "Single-Pointer Adjustments".
Figure 49 presents an illustration of the "Single Pointer Adjustment" Scenario.
Telcordia GR-253-CORE states that the Intrinsic Jitter that is measured (within the DS3 signal) that is
ultimately de-mapped from a SONET signal that is experiencing "Single-Pointer Adjustment" events, must
NOT exceed the value 0.3UI-pp + Ao.
NOTES:
1.
Ao is the amount of Intrinsic Jitter that was measured during the "De-Mapping" Jitter portion of this test.
Continuous Pattern
A4
1.0UI-pp

ping and Pointer Adjustments.
Continuous Add
A5

ping and Pointer Adjustments.
Continuous Cancel
A5
1.3UI-pp
Includes effects of Jitter from Clock-Gapping, De-Map-
ping and Pointer Adjustments.
