  1. A CSG PresentationJanuary 5, 2005 Tom Ball Manager Voice Network Engineering tdb26@cornell.edu

  2. Agenda • VoIP and Cornell, Our Situation • Campus Life Concerns • Student Survey • Cellular Activity • Summary

  3. Legacy PBX Environment • What’s our plan? • When are we going…? • Why….why not?

  4. Current PBX • PBX environment since 1985 • AVAYA DEFINITY PBX • Avaya Communication Manager 1.3 • IP capable PBX supporting soft / hard phones and voice gateways • RFP replaced old G2.2 with G3r in 2001 • “Who Knew?” … seamless transition … • The plan was to be fully capitalized by June of 2005 • In 2000, knew VoIP was coming…

  5. VoIP Technical Considerations • Common Building Infrastructure • Not all Cat 5/6 • Long term upgrade plan…. “EzraNet” • Data Network • Feel good about existing bandwidth & capacity • Not PoE capable switches • Edge network not on UPS • Emergency Power • Large investment to do so • 911 Location Assurance • Data Network jack locations are not as accurate in databases

  6. VoIP Social Considerations • Managing expectations of reliability • Voice Vs. Data availability • Re-tooling and re-training of personnel • Not just the technical staff… • Concept of change & users • You’re thinking of taking out my old phone?!

  7. VoIP Financial Considerations • Justify the full, or partial replacement of a fully capitalized, up to date PBX. • Are there really significant costs savings? • IE: Proprietary Digital set Vs. IP HardPhone • PoE switches • Additional UPS systems • PSTN savings? • Potential Savings for moves, adds & changes?

  8. Graduate Student Thesis, 2003 “Internet Protocol Telephony and The Future of Cornell University’s Telephone System” By: Kevin Byrnes, Graig Diamond, Jonathan Wang Master of Engineering Project Report, sponsored by the Office of Information Technologies at Cornell University. ‘

  9. Scope • The existing voice and data networks at Cornell were analyzed • Voice PBX • Data network, core, edge, I1/2 connectivity • Infrastructure (copper and fiber) • Local / LD costs • Historical traffic trends • Financial considerations • Power systems • 911

  10. VoIP Report Conclusions • Did not recommend an aggressive conversion to VoIP due to: • Full ownership of campus area network • PBX status (capabilities and ownership) • 911 solutions for VoIP are currently weak • Emergency Power / UPS considerations • No recognizable voice WAN cost savings • 80% of Wiring Infrastructure not CAT 5e/6 • Recommended developing a plan to move common infrastructure towards supporting VoIP services. • Stay in tune with developments…

  11. Voice Network Vision • Leverage existing PBX investment • Deploy IP enabled endpoints off the PBX where feasible and economically justified • Develop a long term migration plan for the current PBX • Evaluate how to best provide for future VoIP / SIP capability

  12. Tough Questions - Campus Life • Students: about 4800 phones. • CIT faced questions like: • “We want to lower our costs” • “Can we rip phones out?” • “Has CIT thought about alternatives for students like cellular?”

  13. Approach • Formed a committee of stakeholders • CIT • Campus Life • Cornell Police • Environmental Health and Safety • Purchasing Office

  14. Committee Discussion • CIT offering wireless voice services? • Removing phones from the Residence Halls? • Cellular Services? • Do VoIP technologies fit here? • What about 911 assurance?

  15. Committee Q’s • We had good discussions, candid thoughts, but no answers…. • Is there risk in providing wireless IP devices and NOT providing specific 911 detail? • Cellular in lieu of wired? • We knew others are doing this…so why not?

  16. To Counsel and Risk Management • “Is there a requirement to continue providing wired voice service to students?” • Cellular? • “What if we cannot provide exact location information to the police for 911 purposes?” • Softphones / Cellular

  17. Outcomes • Providing wired phones is essentially a business decision, however: • Need a business plan for further review • More emergency phones / blue lights • Cellular network reliability and availability concerns • Clearly define and communicate expectations for these devices relative to 911. • “This is not your primary means of communications for 911 purposes…use a wired phone or a blue light if threatened” • Must address how wireless devices will fit into 911 and emergency services scheme. (?)

  18. Now What? • Need to better understand student perspectives • Fall student survey… • Annual incoming Freshman • Q’s: Scale of 1 to 5 • About 1,100 respondents

  19. Student Survey QuestionsResNet Phone vs. Cellular • I depend on my ResNet phone in my room • I currently have a cell phone I brought with me • If Cornell offered a cellular service I would use it • I would like a service that rings my cell phone when my ResNet phone rings • My cell phone works well in my residence hall.

  20. I depend on my ResNet Phone • 27% agreed • 18% neutral • 55% said NO

  21. I currently have a cell phone • 85% agreed • 14% don’t • 1% not sure…?

  22. If Cornell offered a cell service, I would use it • 22% agreed • 40% weren’t sure • 38% said no…

  23. I would like a service that rings my cell phone when my ResNet phone rings • 46% agreed • 27% neutral • 28% said NO

  24. My Cell Works well within my Residence Hall • 36% agreed • 17% were neutral • 47% said NO

  25. Cellular Activities • Working with primary cellular providers to: • Improve existing macro coverage • In-Building coverage • Discover developments with next generation networks: CDMA / GSM • Meeting with carriers for network updates and technology “chalk talks” • Site more companies to help offset the loss in traditional voice revenues….

  26. Pending Pilot • Extension to Cellular (EC-500) • Cell phone bridging feature with AVAYA PBX • Additional product? • Staff….clear interest • Students….not sure • Determine impacts on trunk utilization

  27. Closing • Continue to evaluate next steps to support VoIP and SIP • Further define requirements with respect to emergency services • Better understand financial impacts of legacy vs. IP model for our PBX.
