  • The Big Trend - Voice Centric to Data Centric
    • Data services are the dominant traffic type
      • Intranet, internet and email are the main drivers
    • CAGR data service 30-50%, voice 3-5%
      • Source: Adams, Harkness & Hill (2001)
    • Consequence: New network architecture required within the access, edge and core networks

  • Converged Network Architecture RAS Switch Router DSLAM Aggregation Equipment Backbone Equipment Speed Intelligence Converged Networks Deliver Savings CPE Access Edge Core
  • Edge is the Aggregation Point
    • Terminates many traffic types
    • Feeds into ATM and IP core networks
      • IP/MPLS and Ethernet are growing fast
      • No new ATM deployments
    • Supports legacy services
      • T1/E1 and DS3/E3 are included in this
    • High Level of QoS

  • However- Voice is Still the Problem
    • There is a lot of TDM equipment and lines
      • With the downturn, TDM will be around for a long time
      • Capital expenditure is down severely
    • However, suppliers need to address how to migrate voice from voice networks to data networks
    • Service Providers are focusing on operational efficiencies
      • Hence the requirement for converged networks
    • Voice in data networks is not easy
      • More bandwidth does not solve the problem
      • QoS is key, data networks must be engineered to support voice
      • Voice cannot be toll-quality on unmanaged data networks
  • Many Ways to Skin a Cat!
    • VoIP
      • If voice and data are converged at the CPE then VoIP makes the most sense
      • This is the end game of most companies
    • CESoP
      • Circuit Emulation Services
      • If the infrastructure is TDM, and point-to-point, then CESoP makes sense
      • Simpler than VoIP
      • Great at point-to-point links
    • VoWLAN
      • Similar to VoIP, added advantage is mobility
  • Technical Drivers for VoIP
    • Technical Driver 1: Standards and interoperability now largely resolved
      • Will take time to filter through
      • Over the next 24 months growth will be steady before more wide-scale adoption*
    • Technical Driver 2: Natural evolutionary process of migration to VoIP
      • Enterprises and carriers are moving to VoIP now
      • Evolution not revolution

  • Business Drivers for VoIP
    • Business Driver 1: VoIP delivers mission critical services
      • Although this was always true, this was not the perception
    • Business Driver 2: The economics of packet transmission are becoming increasingly transparent to carriers and enterprises
      • We believe VoIP will gain increasing acceptance driven by its relative network simplicity, lower cost structure and ability to carry both voice and data across a single, ubiquitous network*
      • Beyond that we expect momentum to continue to build as new applications/services emerge that homogeneously combine voice/video/data*

  • Market Forecasts (1)
    • We estimate the market for VoIP equipment will grow to approximately $10 billion by 2005 from close to $2 billion in 2001
      • Although slow at present, we think the adoption of VoIP will accelerate in 2004-2005 and continue through the remainder of the decade

  • What is CESoP?
    • CESoP “tunnels” T1/E1 traffic through packet networks whilst maintaining T1/E1 clock and data integrity.
      • Invisible to source and destination
      • Packet network “emulates” a circuit-switched network, re-creating the TDM circuit at the far end

  • Drivers for CESoP
    • Allows ILECs/CLECs to leverage their existing T1/E1 and DS3/E3 infrastructure
    • Whilst moving to packet based networks
    • Allows customers to still get the same service, QoS and peace of mind as they already have
      • Don’t have to invest in new equipment
    • Requires little new equipment

  • The Future VoWLAN (1)
    • Cost of WLAN equipment is falling fast, much in the way Ethernet did
    • WLAN is moving fast
      • This year will be the year of WLAN hotspots
        • Train stations, hotels, airports, coffee shops
      • Today this is only data
    • Additionally, wireless voice is happening in WLANs
      • Several companies have this equipment
      • This will move to WLAN hotspots
  • The Future VoWLAN (2)
    • VoWLAN is inevitable for WLAN
      • It will deliver freedom to VoIP
      • VoWLAN with 2G/2.5G could give 3G serious competition
    • Four major announcements:
      • Lucent UMTS 3G with WLAN.
      • Ericsson partners Agere for WLAN hotspots.
      • Nokia equipment for 2G/2.5G/3G and WLAN hotspots
      • Motorola, Proxim and Avaya partner for Phone/WLAN hand-over
  • The Consequence of Delayed 3G
    • US$107 billion on licenses and infrastructure in Europe
    • The European wireless market now doubts whether it will ever recoup its investment.
    • As a result:
      • Carriers scaling down their 3G roll outs
      • Remain unwilling to spend more until real signs of consumer interest demonstrate themselves
    • However, many European wireless companies are excited about the emergence of Wi-Fi , which many European carriers hope to integrate with their existing GSM/GPRS networks.
