Note 1: The MP-124 24-port, MP-108 8-port, MP-104 4-port and MP-102 2-port

Media Gateways have similar functionality except for the number of channels

(the MP-124 and MP-102 support only FXS), and all versions are referred to

collectively in these release notes as the MP-1xx.

Note 2: MP-10x refers to MP-108 8-port, MP-104 4-port and MP-102 2-port

gateways.

MP-1xx User’s Manual 1. Overview

Version 4.0 17 October 2002

1.1 Introduction

This User’s Manual provides you with information on installation,

configuration, and operation of the MP-124 24-port, MP-108 8-port, MP-104 4-

port and MP-102 2-port 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 Readers are

familiar with regular telephony and data networking concepts.

1.2 Gateway Description

AudioCodes’ MP-1xx telephony Media Gateway provides excellent voice

quality and optimized packet voice streaming over IP networks, enabling

voice, fax, and data traffic to be sent over the same IP network.

Based on AudioCodes’ award-winning, field-proven TrunkPack design, the

MP-1xx uses 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), and to phones or fax (MP-1xx/FXS),

supporting up to 24 simultaneous VoIP calls. Additionally, the MP-1xx is

equipped with a 10/100 Base-T Ethernet port for connection to the LAN.

MP-1xx Gateways are best suited for small to medium-sized enterprises,

branch offices or for residential Media Gateway solutions.

MP-1xx Gateways enable Users to make free local or international

telephone/fax calls between 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.

MP-1xx Gateways are compact devices, designed to be installed either as a

desk-top unit (shown in Figure 1-1 to Figure 1-4 on page 18) or installed in a

19-inch rack (see Figure 2-1).

The MP-1xx supports MGCP (Media Gateway Control Protocol) and

MEGACO (Media Gateway Control) Protocol (ITU H.248 and RFC 3015),

enabling the use 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 voice and telephony signals over a packet network. The

Media Gateways are controlled by a Media Gateway Controller MGC (or Call

Agent) that performs the routing of the calls.

Additionally, for emergency use, the MP-10x/FXS provides a Life Line, connected to

the unused pins on port #4, (MP-102/FXS uses port #2) with a relay to an analog line,

even if the MP-10x is powered off.

The layout in Figure 1-5 on page 19 illustrates an MP-1xx VoIP application.
