Internet port and PC port. Three optional methods of transmission configuration for Skype for
Business phone Internet or PC Ethernet ports:
Auto-negotiate

Half-duplex

Full-duplex

Auto-negotiate is configured for both Internet and PC ports on the Skype for Business phone by
default.
Auto-negotiate
Auto-negotiate 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
Skype for Business 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 Skype for Business phone to transmit in 10Mbps or 100Mbps.
