Physical media
To use the G450 as the endpoint device for a WAN, install a WAN media module and connect
the WAN line to a port on the media module. When you connect a WAN line to a media module,
the G450 serves as the router for the WAN line.
You can also use the fixed ETH WAN Fast Ethernet port as a WAN endpoint by configuring the
port’s interface for PPPoE encapsulation (ADSL modem) or Ethernet-DHCP/static IP (cable
modem).
To use the G450 as a router, connect the external endpoint device to the ETH WAN port on the
G450 front panel using a standard network cable.
WAN line support
The G450 supports the following types of data WAN line:
● E1/T1
● Universal Serial Port
● PPPoE (ADSL modem)
● Ethernet-DHCP/static IP (cable modem)

The table below lists which media modules to install to connect each type of outside WAN line.
