Bit 1 and bit 2 cannot be ON at the same time. Loopback configured through the DIP
switch should be cancelled by the DIP switch. After loopback is configured through
the DIP switch, you cannot enable/disable loopback through the NMS. If you need to
configure loopback through the NMS, make the DIP switch OFF.
5.2 Default configurations
By default, all DIP switches are OFF.
