11.7.8 VDSL2 Impulse Noise Monitoring Profile Setup
Clusters (C in the following diagram) are short groups of severely degraded data symbols used in
monitoring impulse noise. A gap (G in the diagram) is a group of non-severely degraded data
symbols in-between two severely degraded data symbols. The cluster continuation parameter (CCP
in the diagram) sets how big a gap must be to separate a cluster. Clusters can contain gaps smaller
than or equal to the cluster continuation parameter. Gaps larger than the cluster continuation
parameter mark the start or end of a cluster.
