Mediant Series and TP-1610 H.323 User’s Manual 1. Overview
Version 4.6 17 July 2005
1 Overview
1.1 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.
1.2 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 TrunkPackTM 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 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: 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.

Mediant Series and TP-1610 H.323 18 Document #: LTRT-69903
1.3 TP-1610 Overview
The TP-1610 cPCI VoIP media gateway board, based on dual TPM-1100 PMC Modules, is a
complete H.323-compliant ‘two media gateways on a board’, delivering cost-effective solution in a
convenient cPCI form-factor.
The TP-1610 is an ideal solution for H.323 trunking gateways and integrated media gateways for
IP-PBXs and all-in-one communication servers. The board is designed for enterprise or carrier
applications. The TP-1610 provides up to 480 simultaneous ports for voice, fax or data for VoIP
media gateway applications providing excellent voice quality and optimized packet voice
streaming over IP networks. Employing H.323 as a control protocol, the TP-1610 enables
vendors and System Integrators (SIs) short time-to-market and reliable cost-effective deployment
of next-generation networks.
The TP-1610 matches the density requirements for small to medium locations, while meeting
Network Service Providers' (NSP) demands for scalability. The TP-1610, scales from no trunk
spans to 16 E1/T1/J1 spans in a single cPCI slot and provides an excellent gateway solution for
enterprise applications as well as carrier locations.
One or two packet processors (depending on the board's capacity) handle packet-streaming
functions through two, redundant integral 10/100 Base-TX interfaces. Each processor implements
the industry-standard RTP/RTCP packet-streaming protocol, advanced adaptive jitter buffer
management, and T.38 fax relay over IP.
The TP-1610 supports various ISDN PRI protocols such as EuroISDN, North American NI2,
Lucent™ 4/5ESS, Nortel™ DMS100 and others. In addition, it supports different variants of 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 TP-1610 enables 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 H.323 service node (e.g., Call Center) is performed by
the TP-1610 internal routing feature or by a Gatekeeper.
Enabling accelerated design cycles with higher density and reduced costs, the TP-1610 is an
ideal building block for scalable, reliable VoIP solutions. With the TP-1610’s comprehensive
feature set, customers can quickly design a wide range of solutions for PSTN and VoIP networks.
Note: The TP-1610 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 TP-1610 as
a 1-module platform and must be repeated for the second module as well.

1.4 Mediant 1000 Overview
The Mediant 1000 is a cost-effective, converged wireline VoIP media gateway utilizing cutting
edge technology. Intelligently packaged in a stackable 1U chassis, it is designed to interface
between TDM & IP networks as a Customer Premise(s) Equipment (CPE) device. Incorporating
innovative Voice over Packet technology, the Mediant 1000 enables rapid time-to-market and
reliable cost-effective deployment of next-generation networks.
The Mediant 1000 provides superior voice technology for connecting legacy telephone and PBX
systems to IP networks, as well as seamless connection of the IP-PBX to the PSTN. In addition to
operating as a pure media gateway, the Mediant 1000 can also host partner applications and
serve as an IP-PBX platform. The Mediant 1000 is fully interoperable with multiple vendor
gateways, softswitches, gatekeepers, proxy servers, IP phones, session border controllers and
firewalls.
The Mediant 1000 matches the density requirements for smaller locations while meeting service
providers' demands for scalability. The compact Mediant 1000 modular gateway is extremely
scalable and supports multiples of 1, 2, or 4 E1/T1/J1 spans.
The Mediant 1000 can support a variety of telephony interfaces. It contains up to 4 digital
interface modules each with an RJ-48 port. The digital module can be configured as regular
E1/T1/J1 interfaces, and with up to 1 or 2 paired spans acting as life-line telephone interfaces for
switching to the PSTN in case of power failure or network problems.
The Mediant 1000 has enhanced hardware and software capabilities to ease its installation and to
help maintain voice quality. If the measured voice quality falls beneath a pre-configured value, or
the path to the destination is disconnected, the Mediant 1000 can assure voice connectivity by
falling back to the PSTN. In the event of network problems or power failures, calls can be routed
back to the PSTN without requiring routing modifications in the PBX. Further reliability is provided
by dual Ethernet ports and optional dual AC power supply.
The Mediant 1000 extends its flexibility with additional deployment options. The open platform on
the Mediant 1000 offers partners the option to host their own applications (e.g., IP-PBX or call
center application) using a powerful, low-power consumption processor and hard disks to provide
a complete solution within the Mediant 1000 chassis.
The Mediant 1000 supports various ISDN PRI protocols such as EuroISDN, North American NI2,
Lucent™ 4/5ESS, Nortel™ DMS100 and others. In addition, it supports different variants of CAS
protocols for E1 and T1 spans, including MFC R2, E&M immediate start, E&M delay dial / start,
loop start and ground start.
