MediaPack
SIP User's Manual 18 Document #: LTRT-65408
Note 1: MediaPack refers to the MP-124, MP-118, MP-114, and MP-112 VoIP
gateways.
Note 2: MP-11x refers to the MP-118, MP-114, and MP-112 VoIP gateways.
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.
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: The MediaPack is supplied as a sealed unit and must only be serviced
by qualified service personnel.
Warning: Disconnect the MediaPack from the mains and from the Telephone
Network Voltage (TNV) before servicing.
