12.1.2 Functionality
M13860-3 v10
To achieve instantaneous fault clearance for all line faults, scheme communication
logic is provided. All types of communication schemes for permissive
underreaching, permissive overreaching, blocking, delta based blocking,
unblocking and intertrip are available.
The built-in communication module (LDCM) can be used for scheme
communication signaling when included.
