JITTER AND INTERFERING TONE TOLERANCES
The jitter measurements described in this subsection are performed using an ANRITSU model ME502B Digital
Transmission Analyzer, or equivalent.
Jitter Tolerance
ITU-T Recommendations G.823 and JT-G703 specify that network equipment must be able to accommodate
and tolerate levels of jitter up to certain specified limits. The MRT accommodates and tolerates more input jitter
than the level of input jitter specified by these Recommendations.
With input jitter applied to the MRT line side receive input DI1 (pin 29), the MRT properly recovers clock,
decodes the signal, and outputs error-free NRZ data over (and beyond) the ITU-T ranges specified for jitter
input and frequency. Performance characteristics are shown below in Figure 16 (34368 kbit/s operation),
Figure 17 (8448 kbit/s operation) and Figure 18 (6312 kbit/s operation).
