Users are not advised to change the default status.
3.2.2 Fault-Pass-Through Capability Explanation
When Fault-Pass-Through capability is enabled, there are 3 situations that we call it a link
fault.
1．The equipment will monitor the status of remote Ethernet interface. When it changes to
link down from link up, we take it as a link fault of remote Ethernet. At the same time, the
status of local module will change to link down form link up. It will not be recovered until
the fault disappears at remote site.
2．The equipment will monitor the status of remote E1 interface. When it changes to loss of
signal status from normal, we take is as a link fault of remote E1 link. At the mean time,
the equipment will cut off the transmission of local E1 interface but not send AIS signal.
