Application
The Model 3231 is used as a network extender using a PPPoH bridge over DSL. PPPoH is an Ethernet exten-
sion because the same logical LAN exists at both ends of the modems and only bridging is required. PPPoH is
network extension in the more general sense since a different logical network is on each end of the modems.
