Jitter Transfer at the STM-N
Interface
The jitter and wander transfer function at the STM-N interface
depends on the synchronization mode of the equipment. For
details, see relevant definitions in G.783, G.812, and G.813
recommendations.
The jitter transfer function of the SDH regenerator is defined as
follows: The ratio between the jitter of the output STM-N signals
and the jitter of the input STM-N signals varies with the
frequency.
