User's Manual 1. Overview
1 Overview
The Mediant 3000 (hereafter referred to as device ) is a SIP-based Voice-over-IP (VoIP)
media gateway, offering an integrated voice media gateway functionality for voice, data,
and fax streaming over IP networks. The device addresses mid-density applications
deployed in IP networks, by delivering up to 2,016 simultaneous voice channels.
The device is also a fully featured Enterprise class Session Border Controller (SBC),
providing a secured voice network (VoIP) deployment based on a Back-to-Back User
Agent (B2BUA) implementation. The device's SBC application provides control over SIP
signaling and usually also the media streams involved in setting up, conducting, and
tearing down calls.
The device supports various PSTN physical interfaces, depending on implemented blade:

TP-6310 Blade: provides 1+1 protected STM-1/OC-3 interfaces or up to three
scalable T3 PSTN interfaces, which can be connected directly to the PSTN or to the
enterprise's PBX

TP-8410 Blade: provides up to 63 E1 or 84 T1 (DS1) PSTN interfaces, and allows
different and dedicated physical Ethernet ports for each network type (Media, OAMP
and Control)
The device also provides SIP trunking (IP-to-IP and/or Trunk-to-IP) capabilities for
Enterprises operating with multiple Internet Telephony Service Providers (ITSP) for VoIP
services. The device provides full system redundancy, offering an ideal solution for
deploying high-density, high-availability Voice-over-Packet systems.
The device can be offered as a standalone IP-to-IP media gateway, PSTN-IP media
gateway, or a combined PSTN-IP/IP-to-IP media gateway. The supported offering depends
on the installed Software License Key.
The device supports a wide variety of VoIP and cellular vocoders, standards-compliant
signaling and call control, and is based on AudioCodes' VoIPerfect™ architecture core
technology. The device supports a broad selection of voice processing related algorithms
such as G.711, G.723.1, G.729A Vocoders, G.168-2000 compliant echo cancellation, T.38
real-time Fax over IP, a wide selection of in-band and out-of-band tone detection and
generation, as well as signaling protocol support including ISDN PRI.
