Node D squelch map (example)

Connection	SAP node ID	End node ID
b	A	B
c	D	A
d	C	D

If Node D fails, path c is squelched at Node A and path d is squelched at Node C. Path b is not squelched, as the path is rerouted from Node A to Node B by the protection switch. Path a is unaffected by the protection switch, as it does not route through the failed node.
