Direct conversion
On smart-forward mode, the converter can change to direct conversion
automatically when it detects same speed on both TP port and FX port.
Direct conversion method converts the signal between TP port and FX
port without storing the received packet on one port then forwarding to
another port. The media converter operates with the minimum latency.
Note:
1. In direct conversion, be sure both devices connected to the TP port
and FX port have same duplex mode for proper transmission.
2. In direct conversion, 802.3x function is disabled and the media
converter will not generate pause frame, but just forwards the
received pause frame directly from one port to another port.
3. In direct conversion, the media converter is not limited to the
maximal length of the receiving packets.
