PNNI topology state elements (PTSEs) would overwhelm the network if they were transmitted every 
time any parameter in the network changed. To avoid this problem, PNNI uses significant change 
thresholds that control the origination of PTSEs.

Any change in administrative weight (AW) and cell loss ratio (CLR) is considered significant and 
triggers a new PTSE.
