Overview

The AudioCodes Mediant 1000 is a best-of-breed Voice-over-IP (VoIP) H.323 media
gateway, using field-proven, market-leading technology, implementing analog and digital
cutting-edge technology. The Mediant 1000 is designed to seamlessly interface between
TDM and IP networks, providing superior voice quality and optimized packet voice
streaming (voice, fax, and data traffic) over IP networks.
The Mediant 1000 is best suited for small-to-medium size (SME) enterprises, branch
offices, or for residential media gateway solutions. The Mediant 1000 is a highly scalable
and modular system that matches the density requirements for smaller environments, while
meeting service providers' demands for growth.
The Mediant 1000 is ideal for connecting an enterprise's legacy telephones, fax machines
and PBX systems to IP-based telephony networks, as well as for seamless connection of
IP-based PBX architecture to the PSTN. In addition to operating as a pure media gateway,
the Mediant 1000 open platform extends its flexibility with additional deployment options to
host partner applications, known as the Open Solutions Network (OSN) Server for
supporting third-party VoIP applications such as IP-PBX, Pre-Paid, and IP-PBX
redundancy.
The Mediant 1000 is fully interoperable with multiple vendor gateways, softswitches,
gatekeepers, proxy servers, IP phones, session border controllers, and firewalls. The
Mediant 1000 is designed to meet NEBS Level 3 (Bellcore), and regulatory approval
(including Safety, EMC, and Telecom for USA, EU and other countries).
Intelligently packaged in a stackable 1U chassis, the Mediant 1000 gateways are very
compact devices that can be mounted as desk-top units, on the wall, or in standard 19-inch
racks. The Mediant 1000 provides two integral mounting brackets for facilitating the rack
installation.
The Mediant 1000 units are equipped with two 10/100 Base-TX Ethernet ports for
connection to the IP network. The second Ethernet port is used for 1+1 Ethernet
redundancy.
The Mediant 1000 supports mixed digital and analog interface configurations, providing up
to four E1/T1/J1 spans and up to 24 analog interfaces in various FXO/FXS configurations.
The Mediant 1000 digital interface supports multiples of 1, 2, or 4 E1/T1/J1 spans used for
connecting the PSTN or PBX to the IP network. The digital modules provide RJ-48 ports.
The digital module can be configured as regular E1/T1/J1 interfaces, and with up to 1 or 2
paired spans acting as lifeline telephone interfaces for switching to the PSTN in case of
power failure or network problems.
The Mediant 1000 analog interface supports up to 24 analog ports (four ports per module)
in various Foreign Exchange Office (FXO) or Foreign Exchange Station (FXS)
configurations, supporting up to 24 simultaneous VoIP calls. Each analog module
comprises four analog RJ-11 ports. The FXO module can be used to connect analog lines
of an enterprise's PBX or of 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 Mediant 1000 can be used as a PBX for Small
Office Home Office (SOHO) users, and businesses not equipped with a PBX.
The Mediant 1000 has enhanced hardware and software capabilities to ease its installation
and to help maintain voice quality. If the measured voice quality falls beneath a pre-
configured value, or the path to the destination is disconnected, the Mediant 1000 can
assure 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 optional dual AC
power supply.
The Mediant 1000 gateways support H.323 ITU protocol, enabling the deployment of VoIP
solutions in environments where each enterprise or residential location is provided with a
simple media gateway.
