IP Communications Services Trial by Teresa Hastings

1. IP Communications Services Trialby Teresa Hastings Objectives and StrategiesSeptember 29, 1999

2. Evolution Overview Voice over Data Networks IP Desktop Services Integrated Communications Services

3. Purpose • 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

4. StrategiesCustomers • 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

5. Lab Trial High Level Objectives • 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

6. Trial Network Firewall Firewall IP Network Router Router Firewall IPOP Sites Enterprise Sites OSS Systems INCP MWCOM Switch Firewall IP Phones Router Network Gateways Location and Network Servers Announcement Servers Enterprise Gateway AAA Servers PBX ApplicationServers Data Collection Servers

7. 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

8. Desktop Service Features • Priority I Features Local DOD /DID Off-Premise DOD / DID On-Net DOD / DID Single Line Extension Class-of-Service Profile Management (Web interface) Find Me Call Routing Call Forwarding Caller ID Call Screening Dynamic Registration 2nd Directory Number Call Data Records Destination Route Selection Do-Not-Disturb Call Hold Consultation Hold Conference Services Hunt Groups (Circular) Call Transfer End-to-End signaling from Keypad QoS and SLA Monitoring and Reporting • Priority II Features Caller Name Call Pickup 911 Hunt Groups (Busy Order List, Distribution by Usage) Uniform Call Distribution Call Parking CTI (TAPI) Auto-attendant Voice Mail Interface Voice / Unified Messaging Speech Recognition Text-To-Speech Speed Calling Call Queuing Bridging

9. Security Current 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

10. Network Quality Validate Media Path Performance Latency Jitter Packet Loss % Utilization(Bandwidth) Voice Band Data Fax Echo Cancellation Media Negotiation Effects on Performance Feature Quality Validate Signaling Performance Post Dial Delay, Disconnects, Hangings OSS Customer Portal Response Times On-Time Billing/Invoicing Real-Time Billing Billing Accuracy (part of the auditing process) Network Data Collection Product/Rating Definition Timelines Performance Aspects

11. Web Portal Simple web portal for all user interaction with NGOSS for IPTel trial IPTel product and pricing plan creation via Portal Infranet GUI Account Management IPTel customer account management Product Management IPTel product definition, pricing plan management Order Entry Web OE for ordering IPTel services Orderable products and features in Portal Infranet Billing Cycle based billing for flat rate billing Session, feature based rating and billing Bill presentation via web server, printed invoice Generation of flat files for feeding into legacy systems Process Mgmt/Middleware Vitria Businessware based process management for IPTel processes and application middleware. Order Management Support of IPTel order management processes using process management and simple web based workflow capabilities Workflow Management Simple web and e-mail based workflow capability using web server and process management Network Data Collection Vendor (TBD) based support for data collection of billable sessions and events information from IPTel equipment and servers to support IPTel billing. Directory Services Use simple web based repository as directory of users, their profiles, and other user level information Security Simple web server based user_id, password based authentication and authorization Application-application security among NGOSS applications Trial OSS Features

14. 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
