Evolution Overview

Slide 3

Determine customer acceptability of IP-based communications services– Paradigms, features, functionality of Network (IP network), Services and OSS – Targeted at small-to-large businesses– Services included:

• IP Telephony: BI-direction dialing (on/off net) with public/private dialing• Desktop Services features, including IP Phones• Voice messaging

Technology learning– Implement solutions directionally consistent with NGN goals– Not intended to be long-term service platform– Ask questions, try technology and apply learning to long term architecture for

network, services and OSS

Purpose

Slide 4

Customer Selection

– 10 to 15 locations, 30% to 40% of customer site traffic on

the trial

– Will allow some reduction of features

– Willing to turn off the service at end of trial

Internal users first, then external customer(s)

Focus on learning about customer experience and

acceptability

StrategiesCustomers

Slide 5

Testing of customer acceptability of IP Communications Services for business customers

Handle customer communications services on a common IP infrastructure– Core telephony, Desktop services, voice messaging (MWCOM trial)– Intranet services, internet connections (company)

Demonstrate connectivity with customer ATM, FR, PL or IP/VPN Validate OSS concepts and initial implementations Measure performance characteristics Demonstrate initial security solution Reduce infrastructure, development and operations costs Demonstrate Operations Create small number of ‘new’ communications services for inclusion

Trial Core Telephony Services

Enable basic routing services– Basic capability to process DDD/IDDD calls

• Connect existing PBXs to IP network with enterprise gateways• Allow existing end stations to be used

– Access to private dialing plans• Support for VNET based dialing plans

Operator service support via tandem through PSTN network.– No support for 411/911 for Trial– Directory assistance passed to PSTN

Support for basic announcements– Number change, congestion,…

Internet and Intranet services continue with current product offerings

Slide 9

SecurityCurrent Strategy: Use IPSEC AH (authentication header) with IKE (Internet Key

Exchange) between our “known” systems, including SIP servers and gateways

Use SIP sender authentication and message integrity for mobile clients

Long Term Strategy: The long-term model will require development of an effective public key

infrastructure and the use of X.509v3 (or newer) certificates

Issues: IPSEC is relatively new and does not address mobility

No public key infrastructure in place today

Summary It’s not about recreating the switched network Build communications services on the

“disruptive technologies” of the Internet Test alternative service paradigms

– Mixed services– Billing and self-service– Personal policies – E-commerce

Trial the open and interoperable service architecture

Gain invaluable customer insights
