Auto-negotiation is configured for both Internet and PC ports on the IP phone by default.

Auto-negotiation

Auto-negotiation means that all 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 IP phones to auto-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 IP phones to transmit in 10Mbps, 100Mbps or 1000Mbps
(not applicable to SIP-T41P).

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 IP
phones to transmit in 10Mbps, 100Mbps or 1000Mbps (not applicable to SIP-T41P).
