Warnings:
• The device is supplied as a sealed unit and must only be serviced by
qualified service personnel.
• Disconnect the gateway from the mains and Telephone Network Voltage
(TNV) before servicing.
• To protect against electrical shock and fire, use a 26-AWG min wire to
connect FXO ports to the Public Switching Telephone Network (PSTN).
• FXO and FXS ports are considered to be TNV-3
Notes: Throughout this manual and unless otherwise specified, the following terms
are used:
• Device refers to the MediaPack series gateways.
• MediaPack refers to the MP-124, MP-118, MP-114, and MP-112 VoIP
devices.
• MP-11x refers to MP-118, MP-114, and MP-112 devices.
Note: Where ‘network’ appears in this manual, it means Local Area Network (LAN),
Wide Area Network (WAN), etc. accessed via the device’s Ethernet interface.
Note: The terms IP-to-Tel and Tel-to-IP refer to the direction of the call relative to
the AudioCodes device. IP-to-Tel refers to calls received from the IP network
and destined to the PSTN/PBX (i.e., telephone connected directly or indirectly

Notes:
• 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
device 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 device
interfaces between the analog telephone devices and the Internet.
