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.
