1 MP-1xx/H.323 Overview
1.1 Introduction
This document provides the User with the information about installation, configuration and
operation of the MP-124 24-port, MP-108 8-port, MP-104 4-port and MP-102 2-port VoIP Media
Gateways. As these units have similar functionality, except for the number of channels and some
minor features, they are referred to collectively as the MP-1xx. It is expected that the readers are
familiar with regular telephony and data networking concepts.
1.2 Gateway Description
The MP-1xx telephony Media Gateway provides excellent voice quality and optimized packet
voice streaming over IP networks. The product enables voice, fax and data traffic to be sent over
the same IP network. It is based on AudioCodes award-winning, field-proven TrunkPack design
using the AudioCodes well-established DSP voice compression technology.
The MP-1xx incorporates up to 24 analog ports for connection, either directly to an enterprise
PBX (MP-10x/FXO), to phones, or to fax (MP-1xx/FXS), supporting up to 24 simultaneous VoIP
calls.
Additionally, the MP-1xx units are equipped with a 10/100 Base-T Ethernet port for connection to
the LAN.
The MP-1xx Gateways are best suited for small to medium size enterprises, branch offices or for
residential Media Gateway solutions.
The MP-1xx Gateways enable Users to make free local or international telephone/fax calls
between the distributed company offices, using their existing telephones/fax. These calls are
routed over the existing IP Internet or Intranet corporate data networks ensuring that voice traffic
takes the minimum of space on the data network.
The MP-1xx Gateways are very compact devices, designed to be installed either as a desk-top
unit (refer to
Figure 1-2) or installed in a 19-inch rack (refer to Figure 2-1).
The MP-1xx supports H.323 ITU, SIP, MEGACO (H.248) and MGCP protocols, enabling the
deployment of "voice over packet" solutions in environments where each enterprise or residential
location is provided with a simple Media Gateway.
This provides the enterprise with a telephone connection (e.g., RJ-11), and the ability to transmit
the voice and telephony signals over a packet network.
Additionally, for emergency use, the MP-10x/FXS Gateway provides a Life Line, connected to the
unused pins on port #4 (or port #2 for MP-102), with a relay to an analog line, even if the
Gateway is powered off.
The layout diagram, Figure 1-5 on page 15, illustrates a typical MP-108 and MP-104 or MP-102
VoIP application.

$ To connect the cables for Desk-top or Rack-mount go to Step 4 below:
Step 4 When using MP-10x/FXS Gateway, insert each of the RJ-11 connectors on the 2-wire
line cords of the POTS phones into the RJ-11 sockets on the rear of the Gateway.
When using MP-10x/FXO Gateway, insert each of the RJ-11 connectors on the 2-wire
line cords coming from PSTN/PBX into the RJ-11 sockets on the rear of the Gateway
Telephone lines and extensions of up to 7,300 m (24,000 ft) can be achieved using
regular 24 AWG line cord.
Step 5 Insert the RJ-45 connector on the 10/100 Base-T cable from your LAN to the ETH RJ-
45 socket (on the rear of the MP-10x) to provide the link to your LAN.
Step 6 Connect the MP-10x Gateway to the correct AC power supply, and the installation is
now complete.
2.1.5 Installation of the MP-10x/FXS Life Line
Note: The MP-124 and MP-10x/FXO Media Gateways do NOT support the Life Line.
The MP-108/FXS and MP-104/FXS Gateways provide a Life Line connection on port #4.
The MP-102/FXS Gateway provides a Life Line connection on port #2.
This feature provides a wired phone connection to any PSTN or PBX FXS port, upon power-down
conditions. When the power outage occurs, the phone that is connected to the Life Line port (see
above), on pins #2 and #3, is wired to the PSTN or PBX FXS wires on pins #1 and #4 on the
same connector. Therefore, the User of the MP-10x/FXS, can use the phone even when the MP-
10x/FXS is not powered-on. To use this function, the User must utilize a splitter that connects
pins #1 and #4 to another source of an FXS port, and pins #2 and #3 to the POTS phone.
The pinout of the Life Line RJ-11 phone connector is as follows:
1 = Life Line TIP
2 = TIP
3 = RING
4 = Life Line RING
Refer to Figure 2-4 below for the RJ-11 connector pinout.
