Version 6.6 19 Mediant 600 & Mediant 1000
User's Manual 1. Overview
1 Overview
This section provides an overview of the Mediant 1000 and Mediant 600 media gateways.
1.1 Mediant 600
The Mediant 600 (hereafter referred to as device) is a cost-effective, wireline Voice-over-IP
(VoIP) Session Initiation Protocol (SIP)-based media gateway. It is designed to interface
between Time-Division Multiplexing (TDM) and IP networks in enterprises, small and
medium businesses (SMB), and CPE application service providers. Incorporating
AudioCodes’ innovative VoIP technology, the device enables rapid time-to-market and
reliable cost-effective deployment of next-generation networks.
The device is based on VoIPerfect, AudioCodes underlying, best-of-breed, media gateway
core technology. The device provides superior voice technology for connecting legacy
telephone and PBX systems to IP networks, as well as seamlessly connecting IP-PBXs to
the PSTN. The device also provides SIP trunking capabilities for Enterprises operating with
multiple Internet Telephony Service Providers (ITSP) for VoIP services. The device is fully
interoperable with multiple vendors of IP-PBXs, IP Centrex application servers,
softswitches, gateways, proxy servers, IP phones, Session Border Controllers and
firewalls.
The device supports the following interfaces:

Up to two E1/T1/J1 spans (including fractional E1/T1)

Up to eight ISDN Basic Rate Interface (BRI) interfaces

Up to four FXO interfaces (RJ-11 ports) - for connecting analog lines of an enterprise's
PBX or the PSTN to the IP network

Up to four FXS interfaces (RJ-11 ports) - for connecting legacy telephones, fax
machines, and modems to the IP network. Optionally, the FXS interfaces can be
connected to the external trunk lines of a PBX.
When deployed with a combination of FXO and FXS modules, the device can be used as a
PBX for Small Office Home Office (SOHO) users, and businesses not equipped with a
PBX. These interfaces can be provided in one of the following configurations:

1 x E1/T1 port (can support also Fractional E1/T1)

2 x E1/T1 ports

4 x BRI ports (supporting up to 8 voice calls)

8 x BRI ports (supporting up to 16 voice calls)

4 x BRI ports and 1 x E1/T1 port

4 x BRI ports and 4 x FXS ports

4 x BRI ports and 4 x FXO ports

4 x FXS ports and 1 x E1/T1 port

4 x FXO ports and 1 x E1/T1 port
The device supports various ISDN PRI protocols such as EuroISDN, North American NI2,
Lucent™ 4/5ESS, Nortel™ DMS-100 and others, supporting different variants of CAS
protocols, including MFC R2, E&M immediate start, E&M delay dial / start, loop- and
ground-start signaling. The device also supports various ISDN BRI protocols such as ETSI
5ESS and QSIG over BRI. The device also provides dual Ethernet 10/100Base-TX ports
for IP redundancy.
Intelligently packaged in a stackable 1U chassis, the compact device can be mounted on a
desk or in a standard 19-inch rack.
The device provides a variety of management and provisioning tools, including an HTTP-
based embedded Web server, Telnet, Element Management System (EMS), and Simple

Network Management Protocol (SNMP). The user-friendly, Web interface provides remote
configuration using a Web browser (such as Microsoft™ Internet Explorer™).
1.2 Mediant 1000
The Mediant 1000 (hereafter referred to as device) is a best-of-breed Voice-over-IP (VoIP)
Session Initiation Protocol (SIP) Media Gateway, using field-proven, market-leading
technology, implementing analog and digital cutting-edge technology. The device is
designed to seamlessly interface between Time-Division Multiplexing (TDM) and Internet
Protocol (IP) networks, providing superior voice quality and optimized packet voice
streaming (voice, fax, and data traffic) over IP networks.
The device is best suited for small-to-medium sized (SME) enterprises, branch offices, and
residential media gateway solutions. The device is a highly scalable and modular system
that matches the density requirements for smaller environments, while meeting service
providers' demands for growth.
The device is ideal for connecting an enterprise's legacy telephones, fax machines, and
Private Branch Exchange (PBX) systems to IP-based telephony networks, as well as for
seamlessly connecting IP-based PBX architecture to the Public Switched Telephone
Network (PSTN). The device also provides SIP trunking capabilities (including IP-to-IP call
routing) for Enterprises operating with multiple Internet Telephony Service Providers (ITSP)
for VoIP services. In addition to operating as a pure media gateway, the device
incorporates an open platform, known as the Open Solutions Network (OSN) server,
allowing additional deployment options by hosting third-party partner VoIP applications
such as IP-PBX, Calling Card, and IP-PBX redundancy.
The device also provides conferencing services over VoIP networks. This is supported by
an optional Media Processing Module (MPM) that can be housed in the device's chassis.
The MPM module also provides IP Media channels for use on various Media Server
applications.
The device is fully interoperable with multiple vendor gateways, softswitches, SIP servers,
gatekeepers, proxy servers, IP phones, session border controllers (SBC), and firewalls.
The device is designed to meet regulatory approval (including Safety, EMC, and Telecom
for USA, EU and other countries).
Intelligently packaged in a stackable and compact 1U chassis, it can be mounted on a
desk, a wall, or in a standard 19-inch rack. The device is supplied with two integral
mounting brackets for facilitating rack installation.
The device is equipped with two 10/100Base-TX Ethernet ports for connection to the IP
network. The second Ethernet port is used for 1+1 Ethernet redundancy.
The device supports mixed digital and analog interface configurations:

Digital:
•The device supports multiples of 1, 2, or 4 E1/T1/J1 spans for connecting the
PSTN/PBX to the IP network. The digital modules provide RJ-48 ports. The digital
module can be configured with up to 1 or 2 paired spans for switching to the
PSTN in case of power or network failure (PSTN Fallback).
•The device also supports ISDN Basic Rate Interface (BRI) modules for
connecting BRI-based PSTN or PBX lines to the IP network. Each BRI module
supports four BRI ports (RJ-45). Up to five BRI modules can be housed in the
device, supporting up to 20 BRI digital ports. The BRI module can be configured
as 'Lifeline' telephone interfaces, switching to the PSTN in case of power failure
or network problems.
•Depending on configuration, the device can provide IP Media channels at the
expense of PSTN channels. These channels may be used for Media Server
applications.

Analog: The device's analog interface supports up to 24 analog ports (four ports per
analog module) in various Foreign Exchange Office (FXO) or Foreign Exchange
Station (FXS) configurations, supporting up to 24 simultaneous VoIP calls. The device
