The output jitter for jitter frequencies from 0 to 6.6 Hz (for DSX-1 interfaces) or
from 0 to 8.8 Hz (for E1 interfaces) is no more than 0.1 dB greater than the input
jitter, excluding the residual jitter. Jitter frequencies above 6.6/8.8 Hz are
attenuated at a level of 6 dB per octave, as shown in Figure 14 and Figure 15.
