Version 6.4 17 November 2011
SIP 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 Upgrade 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.

SIP User's Manual 18 Document #: LTRT-89712
Mediant 3000
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
(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 'Mediant 3000 High Availability System' on
page 18.
1.1 Mediant 3000 High Availability System
The High Availability architecture of the Mediant 3000 provides the following main
functionality:
Redundant Active/Standby configuration
Support for both TP-6310 and TP-8410 blades
One or many global device IP addresses
Private IP address for each blades for maintenance and fallback.
Upgrading software without disrupting current calls (Hitless Software Upgrade)

Version 6.4 19 November 2011
SIP User's Manual 1. Overview
The device supports a 1+1 redundancy scheme termed High Availability (HA). In HA mode,
the device includes two VoP blades (TP-8410 or TP-6310) and two SA/M3K blades in the
front panel, where one of each blade pair is either in active or redundant mode). The
general architecture of the HA system with TP-8410 and TP-6310 are shown respectively
in the figures below:
Figure 1-2: High Availability System 1+1 of Mediant 3000 with TP-8410
Figure 1-3: High Availability System 1+1 of Mediant 3000 with TP-6310
On the front panel, the active blade occupies Slot 1 while the redundant blade occupies
Slot 3. The SA/M3K blades occupy the front panel's slots 2 (active blade) and 4 (redundant
blade).
The RTMs on the rear of the chassis is according to implemented blade:
TP-8410: the RTM-8410 is located in Slot 2. The RTM-8410 connects to Trunks 1
through 42 (or 1 through 16). Its PSTN and Gigabit Ethernet (GbE) interfaces are
connected to the active VoP blade in Slot 1 of the front panel. The second RTM-8410
is located in Slot 4 and connects to Trunks 43 through 84. Trunks connected to this
RTM are connected to the active VoP blade. Ethernet interfaces are connected to the
VoP blade in Slot 3 of the front panel.
TP-6310: the RTM-6310 occupies Slot 2. Its PSTN and GbE interfaces are always
connected to the active VoP blade in Slot 1 of the front panel. The redundant RTM
(RTM-6310 Redundant) is located in Slot 3 of the rear panel and provides the GbE

SIP User's Manual 20 Document #: LTRT-89712
Mediant 3000
interfaces to the redundant 6310 blade in the front panel's Slot 3. The redundant blade
is not connected to the external network. It only has an internal link with the active
blade. In other words, the user doesn't interact directly with the redundant blade. This
link controls the HA feature and is automatically and internally configured.
Two GbE links can be connected to each VoP blade through their corresponding RTMs
(i.e., for TP-6310: RTM-6310 for the active TP-6310; RTM-6310 Redundant for the
redundant TP-6310). At least one link per VoP blade must be connected, but two links are
recommended for LAN redundancy. After system initialization is complete, network access
is available only to the active blade. The redundant GbE links have no network access.
Each blade (Active and Redundant) has its own private, local IP address (acquired from
BootP/DHCP), which is used only for maintenance. This private address is also used as a
fallback in case of major system problem which prevents the system from working in HA
mode. Typically, this IP address is configured only once (on first time installation of the
system). Afterwards, it can be changed only through BootP/DHCP.
For normal operation, the HA device uses "global" IP address(es). These are the IP
addresses that are used by the Active blade for Media, OAMP and Control interfaces.
These IP addresses are configured in the Multiple Interface table.
1.1.1 Initialization Process
If both VoP blades are already installed when the device powers up, the VoP blade in Slot
1 always initially serves as the active blade, while the VoP blade in Slot 3 serves as the
redundant blade. The active blade is identified by its ACT LED being lit green. If only one
blade is installed, (no matter which slot it occupies), it always assumes the active blade. If
at a later time, a second VoP blade is added, this second blade serves as the redundant
blade.
Synchronization between active and redundant VoP blades may take several minutes in
which the active blade forwards to the redundant blade all its current configuration data.
This data includes files such as voice prompt, call progress tone, and even its software
(cmp file). If necessary, a second boot of the redundant blade is issued to apply the new
configuration.
After the synchronization is complete, the redundant blade is identified by a blinking yellow
light in the ACT LED.
Note: When the active blade synchronizes with the redundant blade, all configuration
changes (e.g., parameter modifications and uploading of files) are blocked
until this process completes and the system is in High Availability mode.
1.1.2 Configuration Stages
For the device to be configured for HA, the following installation stages must be performed:
Hardware configuration setup (refer to Mediant 3000 and IPmedia 3000 Installation
Manual). The system can be set up initially with only one VoP blade and one SA/M3K
blade. However, HA mode is only functional when a second VoP blade and a second
SA/M3K blade are added.
Software Upgrade Key includes the HA feature and is installed on both VoP blades
(see 'Loading Software Upgrade Key' on page 493). (If the HA feature is specified at
the time the system was purchased, then it's already included on both blades).
The device's global IP addresses (i.e., Control, Media, and OAMP) are defined (using
the Multiple Interface table) for the active blade to a valid IP address that is different to
that of the local IP addresses of the blades. In the HA system, when the blades are
initially configured using BootP, the BootP communicates with the two blades using
two different local IP addresses: one for the active and one for the redundant blade.
