2.2.2 MC (Media Converter) Mode
MC (Media Converter) mode is selected and configured using hardware pins: MCCS and MCHS.
Terminal MC mode without port 3 support is enabled when MCCS=0 and MCHS=1. In this mode, port 1 is 100BASE-
FX, port 2 is 10BASE-TX or 100BASE-TX and port 3 is disabled. Terminal MC function is enabled, and the OAM sub-
layer responds to the center MC with OAM frames, such as condition inform reply, loop mode start reply, and loop
mode stop reply.
Terminal MC mode with port 3 support is enabled when MCCS=1 and MCHS=1. In this mode, port 1 is 100BASE-FX,
port 2 is 10BASE-T or 100BASE-TX and port 3 supports MII or SNI interface. Terminal MC function is enabled, and
the OAM sub-layer responds to the center MC with OAM frames, such as condition inform reply, loop mode start reply,
and loop mode stop reply.
Center MC mode with port 3 support is enabled when MCCS=1 and MCHS=0. In this mode, port 1 is 100BASE-FX,
