Telecommunication deregulation state 1995 l.jpg
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.


Telecommunication deregulation federal 1996 l.jpg
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.


Telecommunication deregulation federal 19964 l.jpg
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).


Sorting out the environment l.jpg
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?

Internet and texas state government l.jpg
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.


Internet electronic commerce l.jpg
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


Law enforcement networking issues l.jpg
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.


Video considerations l.jpg
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


Video considerations27 l.jpg
Video Considerations

  • Quantity of time in use

    • Scheduling

    • Usage sensitive

  • Locations

    • How many

    • Same or different

    • Point-to-Point or Multipoint
