Priority of configuration and command of network management software is higher than
configuration of SW1. Configuration of SW1 is invalid when using network management
software to configure.
Note: The other dip-switch SW2 is a 2-bit switch, which shall be used by manufacturing
people. 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. The local E1 interface will not recover until the fault disappears at
OFF (default status)
