Introduction

This document provides you with the information on installation, configuration and operation of
the Mediant 2000 H.323 gateway, digital Mediant 1000 H.323 gateway and TP-1610 H.323 cPCI
board. As these products have similar functionality (with the exception of their physical layout and
the number of trunks), they are collectively referred to in the manual (except for in hardware-
related sections) as the Mediant 2000.

Mediant 2000 Overview

The Mediant 2000 H.323 gateway enables voice, fax, and data traffic to be sent over the same IP
network. The Mediant 2000 Voice over IP (VoIP) gateway provides excellent voice quality and
optimized packet voice streaming over IP networks.
The Mediant 2000 uses the award-winning, field-proven Digital Signal Processing (DSP) voice
compression technology used in other TrunkPack
The Mediant 2000 incorporates 1, 2, 4, 8 or 16 E1 or T1 spans for connection, directly to Public
Switched Telephone Network (PSTN) / Private Branch Exchange (PBX) telephony trunks, and
includes one or two 10/100 Base-TX Ethernet ports for connection to the network.
The Mediant 2000 supports up to 480 simultaneous VoIP or Fax over IP (FoIP) calls, supporting
various Integrated Services Digital Network (ISDN) Primary Rate Interface (PRI) protocols such
as EuroISDN, North American NI2, Lucent™ 4/5ESS, Nortel
supports different variants of Channel Associated Signaling (CAS) protocols for E1 and T1 spans,
including MFC R2, E&M immediate start, E&M delay dial/start, loop start and ground start.
The Mediant 2000 gateway, best suited for large and medium-sized VoIP applications, is a
compact device, comprising a 19-inch 1U chassis with optional dual AC or single DC power
supplies.
The deployment architecture can include several Mediant 2000 gateways in branch or
departmental offices, connected to local PBXs. Call routing is performed by the gateways
themselves or by Gatekeeper(s).
The Mediant 2000 gateway enables users to make low cost long distance or international
telephone/fax calls between distributed company offices, using their existing telephones/fax.
These calls are routed over the existing network ensuring that voice traffic uses minimum
bandwidth.
The Mediant 2000 can be controlled over the network using H.323 (ITU-T) VoIP signaling and
control protocol, which enables the deployment of Voice over Packet solutions in environments
where the enterprise PBX is connected to a VoIP network using the Mediant 2000 as a Trunking
media gateway. This provides the enterprise the ability to transmit voice and telephony signals
over a packet network. The Mediant 2000 can be set up to route calls independently, or
optionally, it can be controlled by an H.323 compliant Gatekeeper that performs the routing of the
calls as well as many other functions.
Note:
Version 4.6
The Mediant 2000 is offered as a 1-module (1-8 spans) or 2-module (for 16
spans only) platform. The latter configuration supports two TrunkPack
modules, each having its own IP address. Configuration instructions in this
document relate to the Mediant 2000 as a 1-module platform and must be
repeated for the second module as well.
