23G/T21(P) E2/T19(P) E2 IP phones support two Ethernet ports: Internet port and PC port. The
CP860/CP920 IP phones have Internet port only. You can enable or disable the PC port on the
IP phones. Three optional methods of transmission configuration for IP phone Internet port or
PC port:
 Auto-negotiate
 Half-duplex
 Full-duplex
Auto-negotiate is configured for both Internet and PC ports on the IP 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
IP phone to automatically negotiate during the transmission.
