MediaPack SIP User's Manual
Where 'network' appears in this manual, it means Local Area Network (LAN),
Wide Area Network (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.
Ensure that you connect FXS ports to analog telephone or to PBX-trunk
lines only and FXO ports to CO/PBX lines only.
The MediaPack is supplied as a sealed unit and must only be serviced by
qualified service personnel.
Disconnect the MediaPack from the mains and from the Telephone Network
Voltage (TNV) before servicing.
