SIP User's Manual 1. Overview
1 Overview
This manual provides you with step-by-step instructions on installing, configuring, and
operating the Mediant 3000 SIP media gateway.
AudioCodes Mediant 3000 (hereafter referred to as device) is aSIP-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 supports various PSTN physical interfaces
(depending on implemented blade):
1+1 STM-1/OC-3 or three T3 interfaces (with the TP-6310 blade)
Up to 63/84 E1/T1 DS1 interfaces (with the TP-8410 blade)
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 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 and multiple UMTS, GSM and CDMA 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.

Mediant 3000
The device's enclosure is a cPCI-based chassis providing 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 (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 such as Fan
Tray and Power Entry modules. All shelf modules (i.e. blades, power supplies, and fans)
are hot-swappable, allowing component replacement while the system is fully operational
with no disruption to service.
The Mediant 3000 can operate in one of the following system modes:
Simplex mode, whereby gateway redundancy is not provided - houses only one set of
blades (one VoP communication blade, one Synchronization and Alarm blade, and
one or two RTMs).
High Availability 1+1 (HA), whereby gateway redundancy is provided if one gateway
module fails. In this mode, the device houses two VoP communication blades (one
Active and one Redundant/Standby), two RTMs, and two Synchronization and Alarm
blades. The Mediant 3000 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. To achieve HA, the software also resides on redundant components and
performs the following:
•Monitors system components to detect any hardware failures
•Handles the switchover procedures to overcome possible failures
For more details on the HA system, refer to ''Mediant 3000 High Availability System''
on page 21.
