V6100 and V7122 User Guide 19

CHAPTER 1: OVERVIEW

This document provides you with the information on installation, configuration and operation

of the V7122 SIP gateway, digital V6100 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 in the guide

(except for in hardware-related sections) as the V7122.

V7122 Overview

The V7122 SIP Voice over IP (VoIP) gateway enables voice, fax, and data traffic to be sent

over the same IP network. The V7122 provides excellent voice quality and optimized packet

voice streaming over IP networks.

The V7122 uses the award-winning, field-proven Digital Signal Processing (DSP) voice

compression technology used in other TrunkPack

TM

series products.

The V7122 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 V7122 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 V7122 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 V7122 gateways in branch or departmental

offices, connected to local PBXs. Call routing is performed by the gateways themselves or by

SIP Proxy(s).

The V7122 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.

20 V6100 and V7122 User Guide

The V7122 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 V7122

internal routing feature or by a SIP Proxy.

The V7122 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 V7122 as a 1-module

platform and must be repeated for the second module as well.

TP-1610 Overview

The TP-1610 cPCI VoIP media gateway board, based on dual TPM-1100 PMC Modules, is a

complete SIP-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 SIP 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 SIP 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.

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 SIP service node (e.g., Call Center) is

performed by the TP-1610 internal routing feature or by a SIP Proxy.

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.
