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


User's Manual 1. Overview

supports up to six analog modules, each module providing four analog RJ-11 ports. The FXO module can be used to connect analog lines of an enterprise's PBX or the PSTN to the IP network. The FXS module can be used to connect legacy telephones, fax machines, and modems to the IP network. Optionally, the FXS module 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.

Media Processing Module (MPM): The MPM module provides IP media channels for conferencing and media server functionality. The device can house up to three MPM modules.

The device has enhanced hardware and software capabilities to ease its installation and to maintain voice quality. If the measured voice quality falls beneath a pre-configured value, or the path to the destination is disconnected, the device assures voice connectivity by 'falling' back to the PSTN. In the event of network problems or power failures, calls can be routed back to the PSTN without requiring routing modifications in the PBX. Further reliability is provided by dual Ethernet ports and an optional dual AC power su
