1.1 Introduction
This document provides you with the 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 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 MediaPack MP-1xx Series
Analog VoIP gateways are cost-effective, cutting edge technology
solutions, providing superior voice quality and optimized packet voice streaming (voice, fax and
data traffic) over the same IP network. These gateways use the award-winning, field-proven
Digital Signal Processing (DSP) voice compression technology used in other MediaPack and
TrunkPack
TM
series products.
The MP-1xx gateways incorporate 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-TX Ethernet port for connection
to the network.
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 network ensuring that voice traffic uses minimum bandwidth.
The MP-1xx gateways are very compact devices that can be installed as a desk-top unit (refer to
Section
3.3.1) or on the wall (refer to Section 3.3.4) or in a 19-inch rack (refer to Section 3.3.3
and Section
3.3.3).
The MP-1xx gateways support SIP (Session Initiation Protocol) or H.323 protocols, enabling the
deployment of "voice over IP" 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 capability to
transmit the voice and telephony signals over a packet network.
The MP-124 supports up to 24 analog telephone loop start FXS ports, shown in Figure
1-1.
