Where ‘network’ appears in this manual, it means LAN, WAN, etc. accessed via
the gateway’s Ethernet interface.
FXO (Foreign Exchange Office) is the interface replacing the analog telephone
and connects to a Public Switched Telephone Network (PSTN) line from the
Central Office (CO) or to a Private Branch Exchange (PBX). The FXO is designed
to receive line voltage and ringing current, supplied from the CO or the PBX (just
like an analog telephone). An FXO VoIP gateway interfaces between the CO/PBX
line and the Internet.
FXS (Foreign Exchange Station) is the interface replacing the Exchange (i.e., the
CO or the PBX) and connects to analog telephones, dial-up modems, and fax
machines. The FXS is designed to supply line voltage and ringing current to these
telephone devices. An FXS VoIP gateway interfaces between the analog
telephone devices and the Internet.
The FXO port is considered to be TNV-3. FXS ports are considered to be TNV-2.
