LABEL DESCRIPTION
Interface Select an interface for which you want to configure here.
PTM: The P-2812HNU-51c uses the VDSL technology for data
transmission over the DSL port.
ATM: The P-2812HNU-51c uses the ADSL technology for data
transmission over the DSL port.
Ethernet: The P-2812HNU-51c transmits data over the Ethernet WAN
port. Select this if you have a DSL router or modem in your network
already.
Current Mode This displays whether the P-2812HNU-51c uses the DSL port or
Ethernet WAN port for Internet access.
When you set the DSL/WAN switch (on the back of the P-2812HNU-
51c) to the DSL side, this displays PTM/ATM WAN. The WAN port
will be disabled automatically.
When you set the DSL/WAN switch to the WAN side, this displays
ETH WAN. The DSL port will be disabled automatically. This allows
the P-2812HNU-51c to work as an Ethernet gateway instead of a DSL
router. To access the Internet, connect the WAN port to a broadband
modem or router.
