2 Initial Connection and Settings
2.1 Power and Network Connections
2.1.1 Connecting to a Network
Prior to the configuration, make sure that broadband Internet access services are available in the current
environment.
With a broadband router
Establish connections between the network hardware by connecting one end of the network cable to the
WAN port of the IP phone and the other end to the LAN port of your broadband router. In most cases,
configure your network settings to DHCP mode.
Without a broadband router
Establish connections between the network hardware by connecting one end of the network cable to the
WAN port of the IP phone and the other end to the LAN port of your broadband modem. If a TV cable
broadband is used, in most cases, you need to set the network mode of your IP phone to DHCP. If
ADSL is used, you need to set the network mod to PPPOE.
With a substitute broadband router
NRP1004/P itself has the broadband routing capability. As long as the WAN port of the NRP1004/P is
properly connected to the broadband modem and the LAN port of the NRP1004/P is connected to your
computer or other devices with Internet capability, you can access the Internet.

User Manual NRP1004 Series IP Phone

NRP1004/P to access the network as long as there is a DHCP server. If there is no DHCP server
available, you need to change the network mode of the NRP1004/P to Static IP or PPPoE according to
the network type.
