To configure PPPoE via phone user interface:

->Network->WAN Port->IPv4->PPPoE IPv4 Client.

2. Enter the user name and password in corresponding fields.

3. Press the Save soft key to accept the change.

The IP phone reboots automatically to make settings effective after a period of time.

Two Ethernet ports on the back of the IP phone: Internet port and PC port. Three optional

methods of transmission configuration for IP phone Internet or PC Ethernet ports:

 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.
