A CSG Presentation January 5, 2005 Tom Ball Manager Voice Network Engineering

Agenda ► VoIP and Cornell, Our Situation ► Campus Life Concerns ► Student Survey ► Cellular Activity ► Summary

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

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…

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

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?!

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?

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. ‘

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

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…

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

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?”

Approach ► Formed a committee of stakeholders  CIT  Campus Life  Cornell Police  Environmental Health and Safety  Purchasing Office

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

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?

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

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. (?)

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

Student Survey Questions ResNet 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.

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

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

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

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

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

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….

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

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.
