scope:

The scope of this ITU-T Recommendation is to define the parameters and the relevant values that are able to control satisfactorily the amount of jitter and wander present at the SDH network-network interfaces (NNI).

SDH network interfaces, to which this ITU-T Recommendation is applicable, are defined in terms of bit rates and frame structures in ITU-T Recommendation G.707; their electrical characteristics are described in ITU-T Recommendation G.703 and the optical characteristics in ITU-T Recommendations G.957 and G.691.

Additional information regarding the architecture of SDH networks is found in ITU-T Recommendation G.803.

Jitter and wander requirements for PDH and synchronization networks are specified in ITU-T Recommendation G.823, for networks based on the first level bit rate of 2048 kbit/s, and in ITU-T Recommendation G.824 for networks based on the first-level bit rate of 1544 kbit/s.

The jitter and wander control philosophy is based on the need:

- to recommend a maximum network limit that should not be exceeded at any relevant interface;

- to recommend a consistent framework for the specification of individual digital equipment (i.e. jitter and wander transfer, tolerance and generation requirements);

- to provide sufficient information and guidelines for organizations to measure and study jitter and wander accumulation in any network configuration.
