MP-1xx

MP-1xx 6 Document #: LTRT-61406

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 MP-1xx is supplied as a sealed unit and must only be

serviced by qualified service personnel.

Warning: Disconnect the MP-1xx from the mains and from the Telephone Network

Voltage (TNV) before servicing.

Note: Where “network” appears in this manual, it means LAN, WAN, etc. accessed

via the gateway’s Ethernet interface.
