PPP interfaces you can define for a Virtual Circuit (VC),
the other type being PPPoE. You can define only one PP-
PoA interface per VC.

is installed by your telephone company where the DSL
line enters your home. The CO also contains splitters that
separate the voice and data signals, sending voice to the
PSTN and data on high-speed lines to the Internet. See
also CO, PSTN, splitterless, microfilter.
