Warning: Ensure that you connect FXS ports to analog telephone or to PBX-trunk
lines only and FXO ports to CO/PBX lines only.
Warning: Disconnect the Mediant 1000 from the mains and from the Telephone
Network Voltage (TNV) before servicing.
Warning: To protect against electrical shock and fire, use a 26AWG min wire to
connect FXO ports to the Public Switching Telephone Network (PSTN).
Warning: The FXO port is considered to be TNV-3. FXS ports are considered to
be TNV-2.
Note: Where ‘network’ appears in this manual, it means Local Area Network
(LAN), Wide Area Network (WAN), etc. accessed via the gateway’s
Ethernet interface.
Note: 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.
Note: Throughout this manual, the term 'Trunk' is used synonymously with 'Hunt'.
Trunk typically refers to digital modules while Hunt typically refers to analog
modules
