The State of Arizona!
What covers half the northern border?What accounts for 2/3 of the topography?Where do interstate highways:– Originate? (States…)– Converge? (Cities…)
Where do most people live?What is the average temperature in SW corner for almost half the year?Who is the ILEC & where are the LATAs?

Phoenix: One of 7 U.S. “City-States”

The Telephony Situation
ILEC is US WestLATAs– Independent– Phoenix– Los Angeles– Tucson
US West has most rural COs up for sale

Arizona Network HistoryState of Arizona “cost reduction”
proposals’87 Dept. of Public Safety - fails’89 Dept. of Admin. - fails’96 DOA recruits Educ. into Project Eagle – fails’99 DOA’s ATS - ???– Phoenix To Tucson ATM
backbone established– V/V/D traffic, US West cell relay
and frame relay to county seats, & dialup all planned
Education’84 NSF “WESTnet”– ’87 56Kb to U. of Utah– ’89, ’91 T1(s), T3 backbone
’90 Az Educ. Telecom Coop. - failed– NAU as “outreacher”, T3 Phx.-Flag.-
Tuc. never used
’93 WESTnet replaced by commercial Internet’97 “Az. Learning Sys.” - failed– Get 1 classroom video codec– All 10 Comm. College Dist.
’99 DoEd admin. Network - ???

Attitudes & Lessons
Health and Human Services – “Our data is too private to go on a shared network.”Public Safety – “Crisis control is mandatory – we are in charge!”Administration – “Telcos should charge one fee for rural and metro! Hmmm, no successful bids…”Transportation – “Require in-kind compensation for rights-of-way for an AZ network? Hmmm…”A Cost Reduction Mission Will Never Establish a New Infrastructure!

What Has Worked?
Quietly connecting up CC/K-12 districts, government IT shops, libraries, and community centers via NSF Connections and DoC TIIAP grants or E-Rate servicesExtension offices and
preceptor support in every county (land grant mission!)

The UofA’s Data NetworksConnected to external networksCampuswide “inter-building” networkWorkgroup or Departmental Computer Connections
– Inter-networked to NSI (3Mb), the commercial Internet (45Mb), and the Internet2 (155Mb)
– Remote sites & State support
– “UAnet backbone network” (1 Gigabit/sec)
– Building infrastructure upgrades (redundant to UAnet, switched)
– Ethernet “walljacks” or ports (10 or 100Mb)

The Arizona Telecommunications System
Arizona’s Department of Administrationhttp://www.ats.state.az.us/
– 1999 mandate - provide common Voice/Video/Data transport– Learned from failure of Project Eagle RFP– Build infrastructure where control exists today, lease services
elsewhere– Costs:
• Development & Implementation: $ 6.4M• Operations (5yr): $79M• Estimated Savings: $98M
