  1. TELECOMMUNICATIONS TECHNOLOGY AND APPLICATIONS Presented By: Eddie Esquivel Department of Information Resources

  2. Telecommunication Deregulation (State -1995) • History: H.B.2128 (74th Legislature) deregulates companies based on criteria: - Allowed for ILECs to “elect” to be deregulated; - Incumbent local exchange companies (ILEC) have Certificate of Need and Necessity (CNN); - Companies can apply for Certificate of Operating Authority (COA); or - Service Provider Certificate of Operating Authority (SPCOA) (reseller of ILEC services); and - Created the Telecommunications Infrastructure Fund Board • Issues : - Applicants for SPCOA must not have more than 6% of the inter-state long distance traffic. Excludes large telephone companies. Must apply for COA. - COA requires building an infrastructure serving 60% of the calling area (investment in new hardware and lines). - SPCOA are given a maximum of 5% discount. - SPCOA are not held accountable.

  3. Telecommunication Deregulation (Federal -1996) • History: FTA96 passed by Congress in 1996. - Restricts states from keeping new companies from entering the local exchange market. - Requires ILECs to provide discounts between 25-35% to resellers (FCC Order). - Allows the Bell companies to enter long distance service based on 14 criteria (state allowed to interpret) and defacto state laws not covered by FTA96. - Universal Service: supported by mark-ups to business lines, local long distance, and long distance access fees. Enhanced service providers are exempt. - Access charge reductions. - ERATE funding.

  4. Telecommunication Deregulation (Federal -1996) • Issues: - Pre-emption of state laws (6% provision and discounts for resellers). - Universal Service issues (deregulated Bells will not charge themselves access charges). - Court Challenges (UNE, resell pricing). - Information services: who pays for the national infrastructure and exemption of Internet service providers (enhanced service providers).

  5. Sorting out the Environment • FCC dealing with Internet access issues (Joint Board); PUC is not (TIFB). • Federal Legislation on Internet Taxes • Long distance carriers lobby the Federal laws; Bells lobby state legislatures. • Current State Legislation: Senate Bill 560. - Reduction in access rates to 6 cents (over time). - PUC authority to deal with cramming, slamming, other provisions. - HB 1701 is companion bill. • When will the Bells get into long distance (UNE issue and OSS)? • Cable companies, Internet access, wireless technology and mergers. • What is an Information Service- video, Internet access, content, multi-apps?

  13. TEX-AN NETWORK Current TEX-AN III Environment • In Existence and Operated by GSC Since 1974 • 2nd Largest Government-Operated Network in the Nation - 26,000 Circuits • Sub-Rate to DS3 Data Services • 27 Million Minutes Per Month of Voice Services • Serves Every Area of the State • 650 Customers - 2/3 Use by Choice • 25% Growth Rate in Services, 15% in Revenues


  15. Technology in State Telecommunications • Greater Austin Area Telecommunication Network (GAATN) - Includes LCRA, AISD, City of Austin, U.T., GSC, Travis County and ACC - Fiber rings around the city (two super loops and eight nodal loops) - Independent development • VidNet: Statewide Video Network. • CAPNet: State complex FDDI ring for interagency communications. • Statewide Data Network. • Statewide Frame Relay Network. • Direct Internet Access. • Internet II: Originally, research network for 31 universities. Since, number has grown and U.T. and A&M have joined. • TEX-AN 2000 will include an ATM switching network.

  21. TEX-AN NETWORK Over 16,000 Locations! Total Eligible Service Locations Data as of September 18, 1998

  22. INTERNET NAPs High speed Internet access points

  23. Internet and Texas State Government • Current Environment: Texas is viewed as a single “Intra-net” by the Internet community. The state is served by the General Services Commission in conjunction with the University of Texas and Texas A&M University. • TXBB: The inter-linked router hub system linking the state Internet Service Providers to the state network “TEX-AN.” • ISPs:AT&T, GTE/BBN, and Sprint have a total of four DS3 circuits. • Issues with Internet addresses: Limited number of addresses split among state entities. Who owns the addresses? • Issues with Common Internet Domain Routing (CIDR) blocks. • Other Internet issues including domain name services (DNS). • Of approximately 210 agencies and universities, 31 agencies do not have web sites. This is not a legislative requirement. • Texas State Library and Archives will provide space on server (TRAIL). • Agencies are required to have an e-mail address.

  24. Internet: Electronic Commerce • Proposed Legislation: • Task Force to make a state portal for business. • Task Force to review what information should be online. • Task Force to review public testimony over the Internet • Rules for broadcasting over the Internet. • Acceptance of Payments over the Internet including use of credit/debit. • Requirement for agencies to include a strategy in their I/R Strategic Plan on using the Internet for accepting forms/registration. • Network Security - Digital Signatures • Network Resource Load • Costs

  25. Law Enforcement Networking Issues • Department of Public Safety (DPS) operates the Texas Law Enforcement Telecommunication System (TLETS) - DPS is designated by the FBI as the central agency for the National Crime Information Center (NCIC) access - TLETS allows all state law enforcement agencies to access NCIC and DPS data, as well as other agency info (TxDOT motor vehicle files, TDCJ crime history files, etc.) • Upgrade of TLETS to meet NCIC 2000 requirements • Issues: Use of TLETS for other functions: - Local law enforcement needs to share data - Local law enforcement sees TLETS as “the state law enforcement network” • Satellite award to Hughes Network Systems.

  26. Video Considerations • Quality video needed for application • Lots of motion • Acoustics • Video Network Speeds • 128 Kbps - PC video, low quality • 384 Kbps (1/4 T1) - Groups • Fractional to T1 - Higher quality • 37 Mbps - Full motion video

  27. Video Considerations • Quantity of time in use • Scheduling • Usage sensitive • Locations • How many • Same or different • Point-to-Point or Multipoint
