Version 6.6 19 Mediant 3000
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.
Figure 1-1: Mediant 3000 Typical Application
The device's chassis provides a compact, rugged 19-inch rack mount unit, 2U high (3.5" or
89 mm), designed to meet NEBS level-3 requirements. The device is a four-slot chassis

User's Manual 20 Document #: LTRT-89729
Mediant 3000
(four front and rear slots) that houses VoIP communication blades, synchronization and
alarm blades, and rear transition modules (RTM). The front and rear blades interface
through a backplane located in the middle of the chassis. The device's chassis' modular
design allows easy add and replacement of modules. All modules are hot-swappable,
allowing component replacement while the system is fully operational with no disruption to
service. The device contains the following main components:

Up to two VoP communication blades

RTM's (amount and type depend on the implemented VoP blade)

Up to two SA/M3K Synchronization and Alarm blades

Up to two Power Entry modules

Up to two Power Supply module
These components function in either an Active/Standby redundant or load-sharing
configuration to provide full continuous performance coverage and are ideal building blocks
for deploying high-density, high availability, Voice-over-Packet systems.
The device can operate in one of the following modes:

Simplex Mode: This mode provides only one VoP communication blade and one
Synchronization and Alarm blade (SA/M3K). In this mode, the device can also support
an optional, integrated CPU (iCPU) for third-party applications.

High Availability 1+1 (HA) Mode: This mode provides system redundancy. The
device houses two VoP communication blades (one active and one standby), two
RTMs, and two Synchronization and Alarm blades. The device's hardware design
contains redundant modules for every part of the system, including redundant network
connectivity, comprehensive switchover processing and backup data storage and
access, as well as applicable load-sharing schemes. In addition, components are hot-
swappable so that they can be replaced while the system is fully operational with no
disruption to service.
To achieve HA, the software resides on redundant components and performs the
following:
•Monitors system components to detect any hardware failures
•Handles switchover procedures to overcome possible failures
For more details on the HA system, see HA Overview' on page 20.
