JITTER TOLERANCE
Jitter Tolerance Definition
Bellcore TA-NWT-000253 (Issue 2), section 5.6.4.2:
"For Category II SONET interfaces, jitter tolerance is defined
as the peak-to-peak amplitude of sinusoidal jitter applied on
the input OC-N/STS-N signal that causes a 1dB power penalty.
This is a stress test intended to ensure that no additional
penalty is incurred under operating conditions."
Jitter Tolerance Requirement
Bellcore TA-NWT-000253 (Issue 2), section 5.6.4.2: "OC-
3/STS-3 and OC-3 Category II SONET interfaces shall tolerate,
as a minimum, the input jitter applied according to the mask in
Figure 3, with the parameters specified in the figure for OC-3."
