Telcordia GR-253-CORE defines a "Continuous Cancel" Pointer Adjustment, as the "Continuous" Pointer
Adjustment pattern, with an additional pointer adjustment cancelled (or not executed), as shown above in
Figure 63.
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 Cancel" pattern of Pointer Adjustments, must not
exceed 1.3UI-pp.

A Review of the DS3 Wander Requirements per ANSI T1.105.03b-1997.
To be provided in the next revision of this data sheet.
8.7
A Review of the Intrinsic Jitter and Wander Capabilities of the LIU in a typical system
application
The Intrinsic Jitter and Wander Test results are summarized in this section.
8.7.1
Intrinsic Jitter Test results
The Intrinsic Jitter Test results for the LIU in DS3 being de-mapped from SONET is summarized below in Table

A detailed test report on our Test Procedures and Test Results is available and can be obtained by contacting your
Exar Sales Representative.
These test results were obtained via the LIUs mounted on our XRT94L43 12-Channel DS3/E3/STS-1 Mapper
Evaluation Board.
These same results apply to SDH/AU-3 Mapping applications.
