OPPORTUNITIES PRESENTED BY USING VoIP




   SHIFTING VOICE USE TO DATA NETWORKS

     VoIP HOLDS OUT THE OFFER OF SAVINGS BY USING ONE
      NETWORK TO CARRY VOICE, DATA, FAX AND MULTIMEDIA



     COULD REDUCE MANAGEMENT OVERHEAD OF NETWORKS



     BETTER UTILIZATION OF IDLE CAPACITY OF DATA NETWORKS.




                                                              5
POSSIBLE IMPACTS TO THE TRADITIONAL VOICE
REVENUE STREAMS


   A KEY ELEMENT IS REGULATION -- WILL A VoIP CALL
    RESULT IN FEDERAL OR LOCAL REGULATION?


   STUDENT CALLING ISSUES
     VOICE MANAGERS KNOW MARGINS (AND REVENUE) CONTINUE
      TO DECREASE

     IMPACT ON CAMPUS PROJECTS AND SERVICES SUPPORT


   FACULTY/STAFF CALLING
     USING PHONES CONNECTED TO DEDICATED PATHWAYS




                                                           6
INTERNAL FINANCIAL MODELS AND BILLING ISSUES



   WHAT SERVICE MODELS DO WE FOLLOW?
     MOST INSTITUTIONS HAVE PROVIDED VOICE SERVICES AS A CENTRALLY
      BUDGETED SERVICE

     LAN SERVICES HAVE BEEN “OPTIONAL” - WE DESIGN AND MAINTAIN TO A
      CENTRALLY FUNDED LEVEL, OR A DEPARTMENT MAY TAKE THE SERVICE
      TO A HIGHER PERFROMANCE LEVEL ON THEIR DIME

     ARE WE HEADING TO A SEPARATION OF QUALITY OF SERVICE DEFINED
      BY THE NETWORKING STANDARDS IN EACH AREA?

     HOW DO WE RECOVER THE COST OF USING THE SERVICE?

     OVERHEAD CONSIDERATIONS -- HOW ARE TOLL CALLING AND
      COMPUTING CHARGES FACTORED INTO OVERHEAD RATES?
         HOW WILL GRANTING AGENCIES CLASSIFY THE CALL, AND WILL IT BE
          CONSIDERED DIRECT OR INDIRECT OVERHEAD?

                                                                         7
            QUALITY OF SERVICE

   INTERNAL AND EXTERNAL SERVICE STANDARDS
    •   SERVICES HAVE TO WORK WITH ALL TELECOMMUNICATIONS SYSTEMS



   RELIABILITY AND SCALABILITY OF THE NETWORKS USED TO
    DELIVER TELEPHONY OVER THE INTERNET
    •   HOW DO WE KEEP THE SYSTEMS WORKING?
    •   WHO MAKES OTHERS KEEP ADEQUATE SERVICES LEVELS?
    •   WHO MANAGES THE NETWORKS THAT NEED TO INTEROPERATE FOR VoIP
        TO WORK?


   ARE WE READY TO SUPPORT INTERNET TELEPHONY USERS?
    •   HELP DESK SUPPORT
    •   EQUIPMENT SUPPORT
    •   TELECOMMUNICATIONS MODEL FOR SERVICE RESTORATION,
        ESPECAILLY TO PROTECT REVENUE STREAMS

                                                                    8
      BASIC SUPPORT BENCHMARKS

   911 services

   Conferencing services

   Directory services for choice of terminating routes in VoIP
    services

   Local Number Portability

   How will competition from ISP’s be handled?




                                                                  9
       POSSIBLE SYNERGY (AND SAVINGS)
         FROM JOINED WORKFORCES


   VoIP COULD BE ANOTHER COMMON DENOMINATOR
    THAT BRINGS TELECOM AND COMPUTING SERVICES
    CLOSER TOGETHER

   POSSIBLE SAVINGS IN OPERATIONS (COMBINED
    FUNCTIONS FOR INFRASTRUCTURE, NETWORK
    ADMINISTRATION AND MAINTENANCE)

   TRAINING ISSUES REGARDING TECHNICAL SUPPORT,
    AND COSTS ASSOCIATED WITH TRAINING



                                                   10
             Next Steps

   CONTINUE TO MONITOR OPPORTUNITIES FOR USING VoIP,
    ESPECIALLY FOR INTRANET USE

   EXPLORE THE SYNERGY OF TRADITIONAL VOICE CALLING
    WITH VoIP CALLING

   FOLLOW THE REGULATORY SCENE VERY CLOSELY

   LOOK FOR THE SERVICE TO MATURE INTO A STANDARD
    THAT WILL PROVIDE BENEFITS TO ALL
