Basic Network Overview

Before using the UC-Series VoIP PBX in your network, you must configure the basic network.

Network interfaces

UC-Series VoIP PBX supports LAN interface and WAN interface. By default, the WAN interface is enabled, and the LAN interface is disabled.

According to your network environment, you may need to use dual network interfaces.

If you use dual network interface, the system route entries are automatically created for the default network interface. To properly route the network traffic through the desired network interface, you need to add a static route on the PBX.

Ethernet modes

UC-Series VoIP PBX supports three Ethernet modes:

• Single: Only LAN port will be used for connection, WAN port is disabled.
• Double: Both LAN port and WAN port can be used for connection. If you use Double mode, you need to choose a default network interface for the PBX.

IP address assignment

UC-Series VoIP PBX supports three types of IP address assignment:

• Assign a static IP address

Contact your network administrator to assign an IP address to the PBX. Then you need to manually configure settings such as the IP address, subnet mask, default gateway, and DNS servers on the PBX.

• Obtain an IP address from a DHCP server

You can configure the PBX to automatically obtain its IP address when it starts up from a DHCP server running in your network.

Note: The IP address assigned to the PBX may vary every time the PBX is started up.
