Transforming CommunicationsThrough End-to-End

Voice over IP Solutions

A breakthroughtechnology

has reached critical mass.

Yesterday’s Voice over IP (VoIP) hype hasbecome today’s market reality. Major carriershave rolled out services that are attractingsubscribers with rich and affordable newfeatures, such as number portability, callredirection, conferencing, e-mail integration,Web-based communications managementand more. Residential gateways and clientdevices for VoIP are proliferating in theconsumer marketplace, and according toIDC, 37% of large and medium-sized U.S.firms with PBXs have already deployed VoIP-based equipment.1 Additionally, Infonetics has projected that global revenue from carrierVoIP equipment will reach $4.7B in 2007, up from $1.3B in 2003.2

The reasons for this growth are many. VoIPtechnology (the transmission of voice aspackets over IP networks) has matured andinteroperability issues are being resolved;broadband connectivity is growing andincreasingly affordable; and today’s high-bandwidth wireless LAN solutions candramatically extend access to VoIP services.These factors have created an environment that is primed for VoIP rollout and adoption.Everyone—from carriers to end-users—ismotivated to make the transition, and for thesame reasons: VoIP enables richer, morepersonalized and better integrated services at reduced cost.

VoIP opens the door to smart communication devices that

will be instrumental in transforming the communications

experience. Users will be able to access diverse media,

including voice, e-mail, instant messaging, Web sites,

video, applications and data, not only from their desktops

and notebooks, but also from cell phones, desk phones,

PDAs and entertainment devices such as set top boxes.

As functionality increases, smart devices will support more

intuitive interfaces, cross-network access, and seamless

device-to-device communications to enable a simpler and

more unified end-user experience. Information will flow

more freely, and people will spend more time communi-

cating and less time managing their communications.

Powerful clients are key to customer value.User expectations are already high, and will only increase

over time. There are several user segments to consider. In

each case, powerful and versatile client devices are key to

the value and success of VoIP services for end-users in

both home and office settings.

• Individual users want high-quality multimedia, fast

processing, ubiquitous connectivity and long battery life

in innovative designs that are easy to carry and use.

• Businesses need powerful, affordable and reliable

clients that keep employees productive and can be

managed securely and remotely.

• Service providers need all the above and more. Their

success depends not only on satisfied subscribers, but

on the ability to quickly deploy, manage, provision and

upgrade services across thousands or millions of

client devices, while keeping their support costs to

a minimum.

For end users:A simpler and richer VoIP experience.

Intel is driving innovation and value across all these requirements.Substantial computing resources are required to deliver a

secure, high-quality voice experience. Connections must

be made, signals must be encoded and encrypted,

and firewalls and virus scans must run smoothly in the

background. Multitasking adds to the load, as users

simultaneously search the Web, check e-mail and use

productivity applications. To support these demands

across diverse user segments, Intel is:

• Integrating Intel® High Definition Audio, which enables

mainstream computing and communications devices to

deliver CD-quality sound.

• Integrating multiple network connectivity options (e.g.,

Ethernet, Wi-Fi, 2.5G/3G, Bluetooth, etc.) for better

connectivity and mobility.

• Focusing on interoperable standards, such as Session

Initiation Protocol (SIP), that simplify integration and

reduce costs.

• Optimizing performance and power consumption to

enable small mobile platforms that deliver high-quality

voice and multimedia, while helping to extend

battery life.

By working with a broad community of vendors, Intel is

driving these capabilities into a wide variety of next-

generation client designs that deliver market-leading

capabilities for virtually all segments, at price points that

will help drive broad adoption:

• Smart phones and PDAs—Intel® Personal Internet

Client Architecture (Intel® PCA) with Intel XScale®

technology delivers powerful multimedia and commu-

nications capabilities, with exceptional performance

per watt.

• Notebooks—Intel® Centrino™ mobile technology

delivers outstanding mobile performance while enabling

great battery life, with integrated wireless LAN capabili-

ties+ in lightweight notebook designs to fit user needs.

• Desktops—Intel® Pentium® 4 processors supporting

Hyper-Threading Technology3 power high-performance

PCs that are easily transformed into versatile, high-

quality personal communications hubs.

Intel components also support other platforms for the

home, such as residential gateways and set top boxes,

which extend the value of client devices and enable cost-

effective integration of VoIP services. As these clients and

support devices proliferate in the marketplace, users,

businesses and service providers will all derive higher value

from their VoIP investments, through better voice quality,

enhanced price/performance, broad interoperability, and

rapid, ongoing innovation.

For businesses:Flexible, affordable and

comprehensive VoIP solutions.Businesses are shifting to VoIP so they can integrate voice,

data and applications more flexibly to improve communica-

tions and accelerate business processes. Key advantages

include:

• Enhanced productivity: From presence detection and

instant messaging, to ad-hoc multi-conferencing, VoIP

can enable a new level of instant teamwork, reducing the

time spent tracking down individuals and information,

and providing a single interface for users to manage their

communications.

• Better customer service: Businesses can improve the

integration of customer data, support applications, and

voice to deliver more efficient, unified and increasingly

automated services across multiple business sites,

functions and media.

• Flexible mobility: VoIP over wireless LAN can be used

to enable seamless communications virtually anywhere in

wireless-enabled enterprises, public hotspots, and home

offices, with better quality than cellular services.

• Lower cost: By moving all their communications onto

their IP network, businesses can realize direct savings

through lower service costs, especially for long distance

and audio conference calls. They can also reduce IT sup-

port costs, since they have only one network to manage

and VoIP uses bandwidth more efficiently than traditional

circuit-switched solutions.

Optimized solutions for businessenvironments.In addition to the full range of client devices described

earlier, Intel collaborates with leading vendors to deliver

high-quality VoIP infrastructure solutions for businesses of

all sizes, whether they are looking to replace their current

telephony solution, connect to external hosted services,

or complement and extend their existing Private Branch

Exchange (PBX). Based on high-performance Intel silicon,

boards and software building blocks—and key standards

such as Real Time Protocol (RTP) and Session Initiation

Protocol (SIP)—these platforms integrate well with legacy

systems. They can also be scaled and extended to support

business growth and new functionality.

• For small offices and home offices, Converged

Access Platforms (CAPs) based on Intel reference designs

combine multiple, tightly-integrated features, such as rout-

ing, firewall, wireless LAN and VPN support. This all-in-one

approach simplifies deployment and keeps costs low,

while enabling high-quality VoIP solutions with very little

management overhead.

• For larger businesses and enterprises, Intel pro-

vides components for IP PBX systems, as well as applica-

tion, call control and media servers that can be scaled and

adapted to match specific business requirements. Intel

building blocks enable converged solutions that support

both VoIP and traditional connections for easy integration

into virtually any business telephony environment. Pure IP

solutions are also supported, along with IP-PBX gateways

for connectivity to the Public Switched Telephone Network

and traditional phones. With these options, businesses

have substantial flexibility for deploying VoIP to selected

users and business sites, so they can optimize their return

on investment through a phased rollout.

A key enabler of these solutions is Intel® NetStructure™

Host Media Processing (HMP) software. This revolutionary

technology eliminates the need for specialized digital signal

processing chips (DSPs) by providing a more affordable

software-based alternative that delivers scalable, high-

quality voice and video on standards-based platforms.

Supporting and extending VoIP solutions. Products, standards and technologies for VoIP and

multimedia communications continue to advance, so

business value depends on solutions that can be scaled

and adapted without disruptive overhauls. Intel works

with leading standards bodies and a large community of

vendors to deliver high-quality solutions that support cost-

effective evolution toward next-generation standards and

features. A variety of business applications are available,

providing extensive support for advanced communications

capabilities such as presence detection, conferencing,

unified messaging, application sharing, interactive voice

response, text-to-speech translation, integrated contact

center functionality and more.

The availability of solutions based on Intel products and

technologies continues to grow rapidly, and the use of Intel

hardware and software building blocks helps to ensure

that these diverse solutions are widely interoperable. Intel

also supports multiple platform options, including Intel

architecture-based rack-mount servers and Compact PCI

(cPCI). This flexibility is helping vendors develop high-

quality solutions that address the full range of business

requirements. As a result, companies have the flexibility

they need to grow their voice and multimedia over IP

solutions using cost-effective, standards-based platforms

that keep their costs down and their options open.

For service providers: Accelerating time-to-market and reducing costs.

Revenue from traditional voice services continues to drop,

and many carriers and service providers are looking to VoIP

and related services, such as Push-to-Talk and Video-on-

Demand, to drive up average revenue per user (ARPU) and

improve subscriber loyalty. To deliver competitive value,

these new services must be deployed quickly, yet VoIP

and other IP-based technologies introduce new technical

challenges. They add complexity, by requiring extensive

data plane and control plane integration, and they must be

scaled and adapted frequently to keep pace with evolving

market expectations. Successful deployment requires:

• Customer Premises Equipment (CPE) that is affordable,

highly reliable and exceptionally simple to install, provision

and manage.

• Carrier-grade access and core network solutions that are

flexible, scalable and extensible, and can be layered on

existing network and Operations and Business Support

System (OSS/BSS) infrastructure.

Intel is driving innovation and market-leading solutions

for both requirements, and offers extensive development

support, as well as joint-marketing opportunities to

increase market visibility and accelerate payback.

Intelligent, integrated and affordable CPE solutions.• Converged Access Platforms (CAPs)—With carrier-

grade quality of service and integrated features such as

routing, firewall, wireless LAN, and VPN support, these

multi-function devices simplify installation and operation,

while providing over-the-wire manageability in a single,

affordable box. Intel’s CAP reference design for residential,

home office and small business is powered by Intel®

network processors. It has been adopted by multiple

vendors and their products are now available in retail

outlets in the U.S. and Japan.

• Set top boxes—Validated combinations of Intel®

Architecture Processors and chipsets deliver the perform-

ance and processing headroom required for IP digital set

top boxes and other consumer electronics devices. Intel

has developed reference designs and development

platforms that enable manufacturers to target the require-

ments of service providers and consumers, providing the

flexibility to support “triple-play” IP-based voice, video

and data services. Digital set top boxes based on these

designs can be remotely managed, upgraded and

provisioned, and have been adopted by multiple vendors.

Access and core network solutions—modular, scalable and easier to deployIn many areas of their network, carriers and service

providers are tied to legacy solutions based on proprietary

platforms. As a critical new technology, VoIP and multi-

media over IP offer key opportunities to move toward

modular, industry-standard solutions that can be integrated

and upgraded more easily. Two solutions are especially

significant with respect to VoIP.

• Broadband Remote Access Servers (B-RAS)—

Deployed at the network edge, these systems allow

service providers to converge multiple traffic sources

(DSL, cable, broadband wireless, Ethernet, etc.) onto a

single network, while consolidating security and call

tracking services and supporting differential billing.

• IP Multimedia Subsystems (IMS)—Based on a

3GPP4-defined architecture, IMS is specifically designed

to deliver flexible and extensible VoIP and multimedia

services that can evolve with market trends. Network

capabilities are deployed via dedicated IP Media Servers,

and services are layered on top via separate application

servers. By abstracting network and application function-

ality, this architecture allows functions to be scaled and

upgraded independently, largely eliminating the traditional

“rip and replace” approach to new service deployment.

Both B-RAS and IMS are ideally suited to modular commu-

nications platforms based on Intel building blocks (silicon,

software, boards and chassis) and the AdvancedTCA*

(ATCA) specification. ATCA was designed from the ground

up for delivering converged applications on modular,

carrier-grade platforms that are more scalable, flexible and

affordable than proprietary designs. It allows Telecommuni-

cations Equipment Manufacturers (TEMs) to combine best-

of-breed, third-party building blocks to reduce development

costs and accelerate time to market.

As part of this standards-based approach, Intel Architec-

ture Processors can be used to support control plane

functions and Intel network processors to support data

plane functions. This results in boards and platforms that

can be scaled and adapted through component and

software upgrades. For service providers, this means

enhanced agility for delivering and adapting new services.

AT&T and Intel are workingtogether to develop a number ofVoIP services and to help drivestandards. Products based on

Intel’s Converged AccessPlatform (CAP) reference designhave already been certified for

use with AT&T CallVantage*

Service and are availablenationwide. Over time, additionalhighly-integrated products with

enhanced security and callmanagement capabilities will

be targeted for small andmedium-sized businesses.

“We look forward to working inclose cooperation with Intel to

develop innovative VoIP servicesand technologies. There is no

doubt that the future ofcommunications resides ondelivering high-quality, cost-

effective VoIP solutions to bothbusiness and residential

customers.”Christopher Rice,

Director of Access Technologies Research, AT&T Labs

4 Established in 1998, the 3rd Generation Partnership Project (3GPP) brought together a number of telecommunications standards bodies to produce a global specification for mobile communications.

VoIP is the first step in a massive transformation that is

driving the communications industry toward business and

consumer solutions that:

• Are richer, more personal, better integrated and more

satisfying.
