they can receive data.
•
In Full-Duplex mode data can be transmitted and received at the
same time.
However:
a) Full-Duplex transmission is only possible between two devices
with a dedicated link (e.g., Switch-Switch, Switch-PC)
b) Both devices must have Full-Duplex capability
c) Both devices must be set to Full-Duplex (e.g. Auto-
Negotiation – Auto-Negotiation, Non-Auto-Negotiation to Non-
Auto-Negotiation)
•
The 100BASE-TX/10BASE-T ports on the Switch detect and set the
line's operating mode by using their Auto-Negotiation function.
Auto-Negotiation
Every 100/10Mbps dual speed port on this LevelOne FSW-1611TX
10/100Mbps Fast Ethernet Switch has a built-in "Auto-Negotiation"
function. This technology automatically sets the best possible
bandwidth as soon as a connection is established with another network
device (usually at Power “On” or Reset). This capability is achieved via
the Switch’s Auto-Negotiation function that automatically detects the
modes and speeds the second (attached) device is capable of.
Evaluating Auto-Negotiation Capability:
If the attached device is: This Switch Will Automatically Set Its
TP Ports to Operate At:
100Mbps, no Auto-Negotiation 100Mbps Bandwidth
(100BASE-TX, Half-Duplex)
100Mbps, with Auto-Negotiation 200Mbps Bandwidth
(100BASE-TX, Full-Duplex)
10Mbps, no Auto-Negotiation 10Mbps Bandwidth
(10BASE-T, Half-Duplex)
