Auto-Negotiation and Speed Sensing
All of the TN-5308’s Ethernet ports independently support auto-negotiation
for speeds in the 10BaseT and 100BaseTX modes, with operation according
to the IEEE 802.3u standard. This means that some nodes could be operating
at 10 Mbps, while at the same time, other nodes are operating at 100 Mbps.
Auto-negotiation takes place when an M12 cable connection is made, and
then each time a LINK is enabled. The TN-5308 advertises its capability for
using either 10 Mbps or 100 Mbps transmission speeds, with the device at the
other end of the cable expected to advertise in the same way. Depending on
what type of device is connected, this will result in agreement to operate at a
speed of either 10 Mbps or 100 Mbps.
If a TN-5308’s Ethernet port is connected to a non-negotiating device, it will
default to 10 Mbps speed and half-duplex mode, as required by the IEEE
802.3u standard.
