Auto-negotiation
Auto-negotiation means that two connected devices choose common transmission
parameters (e.g., speed and duplex mode) to transmit voice or data over Ethernet. This
process entails devices first sharing transmission capabilities and then selecting the
highest performance transmission mode supported by both. You can configure the
Internet port and PC port on the IP phone to automatically negotiate during the
transmission.
Half-duplex
Half-duplex transmission refers to transmitting voice or data in both directions, but in one
direction at a time; this means one device can send data on the line, but not receive
data simultaneously. You can configure the half-duplex transmission on both Internet
port and PC port for the IP phone to transmit in 10Mbps or 100Mbps.
Full-duplex
Full-duplex transmission refers to transmitting voice or data in both directions at the
same time; this means one device can send data on the line while receiving data. You
can configure the full-duplex transmission on both Internet port and PC port for the IP
phone to transmit in 10Mbps or 100Mbps.
