Audio Conferencing Server
CallRecording
Legacy TDM Network

• Services delivered as stand-alone Service Nodes
• Each Service Nodes often has their own
• Proprietary architecture
• Management systems and service databases
• Often tied to a access network subset
• Resulting characteristics and operational
  limitations
• Multiple systems and databases to manage
• Voice only -gt complex interworking with IP-based
  data services
• New service introduction complex and slow

• Service Nodes decomposed into
• Application logic and
• Media processing.
• Application logic executes on off-the-shelf
  servers.
• Media processing is shared across many services.
• Interconnection through open standards-based
  interfaces.

AdvancedTCA (ATCA) Common Reusable Platform

• ATCA is a hardware platform specification for
  telecom equipment manufacturers.
• Enables manufacturers to design plug-compatible
  equipment and components that work together.

• Provisionable ATCA Cards for
• Network Processing,
• Digital Signal Processing (DSP),
• Data Processing,
• Switching,
• Storage
• etc.

Common ATCA Hardware Chassis
Reusable Platform Provisionable For
ManyTelecommunication Applications

• OS and
• System S/W
• High Availability
• Platform Management
• Security
• etc.

IMS Benefits for Enterprise Customers (and
their suppliers)

• One Architecture for Any Service
• Supports Multimedia and Multimodal services
• One Architecture for Any Access Technology
• Abstraction of access technologies allows a
  single service architecture to support any
  device.
• Rapid Service Introduction
• Reuse of common infrastructure accelerates adding
  new service capabilities and features
• Maximize Flexibility
• Mix and match best-of-breed equipment and
  applications using open standards-based interfaces

Real-World Example Enterprise with Decomposed
Services

• Fortune 500 Company
• 160 countries,
• 1500 locations,
• 900 PBXs in
• 700 facilities,
• 400,000 phones,
• 450 voicemail systems,
• 160 IVR systems,
• 156 call centers
• IP network implemented to consolidate, improve
  management and resiliency, and enable voice as
  an on demand application
• Infrastructure delivering over 1 Billion
  conferencing minutes per year (50 savings) and
  leveraging same infrastructure for IVR and
  Voicemail applications as well as fixed/mobile
  convergence.

Conclusions and Trends

• VoIP in Enterprise is growing
• However, Service Node architectures are still
  common
• The design driver is reuse
• Service decomposition allows many applications to
  share multimedia processing and control
  infrastructure
• IMS extends service decomposition to any access
  network
• ATCA delivers similar reuse qualities in hardware
  platforms
• Benefits include rapid service innovation with
  lower costs.
• Carriers are leading the way towards IMS
  architectures
• Expect IMS adoption in Enterprise to accelerate
  quickly.
