1 Overview
1.1 Introduction
This document provides you with the information on installation, configuration and
operation of the Mediant 2000 SIP gateway, TP-1610 SIP cPCI board and TP-260 SIP PCI
board. As these products have similar functionality (with the exception of their physical
layout and the number of trunks), they are collectively referred to throughout this manual
(except for in hardware-related sections) as the gateway.
1.2 Mediant 2000 Overview
The Mediant 2000 SIP Voice over IP (VoIP) gateway enables voice, fax, and data traffic to
be sent over the same IP network. The Mediant 2000 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
TM
series products.
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
™
DMS100 and
others. In addition, it 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 SIP Proxy(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 also route calls over the network using SIP signaling protocol,
enabling the deployment of Voice over Packet solutions in environments where access is
enabled to PSTN subscribers by using a trunking media gateway. This provides the ability
to transmit voice and telephony signals between a packet network and a TDM network.
Routing of the calls from the PSTN to a SIP service node (e.g., Call Center) is performed
by the Mediant 2000 internal routing feature or by a SIP Proxy.
Note: The Mediant 2000 is offered as a 1-module (up to 240 channels or 8 trunk
spans) or 2-module (for 480 channels or 16 trunk 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.
